A composition for colloidal crystals including core-shell particles and a monomer having a particular structure. The core-shell particles constitute 25% to 65% by weight of the composition, and the monomer constitutes 35% to 75% by weight of the composition. The core has an average particle size from 50 to 900 nm. Each particle includes a core and a shell. The shell is formed of a linear polymer composed of at least one of styrene and a monomer having a particular structure. One end of the linear polymer is covalently bonded to the core. The refractive index of the core (n(core)) satisfies the following formulae: wherein R1 denotes a hydrogen atom or a methyl group, and y is 0 or 1, n(shell)−n(core)≧0.07, n(shell) denoting the refractive index of the shell, and n(B)−n(core)≧0.07, n(B) denoting the refractive index of the monomer (B1) after curing.

Regardless of the type of biological tissue, a sufficient joining force can be quickly obtained; the problem of an adhesive bonding biological tissue other than the target biological tissue can be prevented; and the adhesive can be prevented from becoming impossible to apply due to curing. There is provided a biological-tissue joining apparatus including an energy supplying part that clamps, with pressure, biological tissue to be joined and melts protein in the clamped biological tissue by supplying energy to the biological tissue; and an adhesive supplying part that supplies an adhesive to the biological tissue, wherein the adhesive supplying part includes a discharge port that discharges the adhesive to a contact surface of the energy supplying part in contact with the biological tissue.

A developing device includes: a developing roller incorporating a fixed magnet body having a plurality of magnetic poles in a circumferential direction; a regulating member for regulating an amount of toner on the developing roller by means of a magnetic field formed by the regulating member and the fixed magnet body; and a magnetic-field generating member for scraping off, on an upstream of the regulating member in a rotational direction of the developing roller, toner which is not used for development on the developing roller. A relation Bm/Br>1 is satisfied, where Br represents a magnetic flux density of a distal end portion of the regulating member facing a surface of the developing roller and Bm represents a magnetic flux density of a distal end portion of the magnetic-field generating member facing the surface of the developing roller.

A hardcoat layer is a cured layer comprising a curable resin-precursor, a thermoplastic resin, and a fine particle having an average primary particle size of 1 to 100 nm, and the hardcoat layer is formed on at least one side of a transparent film. The thermoplastic resin may be a thermoplastic resin (particularly, a cellulose derivative) nonreactive to the curable resin-precursor. The ratio of the metal oxide fine particle is about 0.5 to 4 parts by weight relative to 100 parts by weight of the curable resin-precursor. The metal oxide fine particle may comprise at least one fine particle selected from the group consisting of antimony tin oxide, tin oxide, and zinc oxide. The curable resin-precursor may comprise a tetra- or more-functional precursor. The optical film of the present invention has excellent anti-glareness or anti-Newton-ring property and also has excellent abrasion resistance and mechanical properties.

An anti-Newton-ring film for effectively preventing generation of Newton rings in a resistive touch panel is provided.The anti-Newton-ring film is obtained, with the use of a liquid phase containing one or more polymers, one or more curable resin-precursors, and a solvent, through a step for forming a phase-separation structure by spinodal decomposition of (i) a plurality of polymers, (ii) a combination of a polymer and a curable resin-precursor, or (iii) a plurality of curable resin-precursors, from the liquid phase concurrent with evaporation of the solvent, and a step for curing the resin-precursor to form an anti-Newton-ring layer. In the film, the anti-Newton-ring layer has an uneven surface structure, isotropically transmits and scatters an incident light, shows a maximum value of a scattered light intensity at a scattering angle of 0.1 to 10°, and has a total light transmittance of 70 to 100%.

An anti-glare film which can prevent reflected glare in a display and a whitening in a displayed black image and provide a contrasty image display in which black color appears more sharply is provided.The anti-glare film is produced by applying a liquid composition containing a nonreactive (meth)acrylic resin having a weight-average molecular weight of 30,000 to 1,000,000, a (meth)acrylic resin having a weight-average molecular weight of 1,000 to 100,000 and a polymerizable group, a polyfunctional (meth)acrylate, and a solvent having a boiling point of not lower than 100° C., and producing convection along with volatilization of the solvent, wherein the anti-glare film has a ridge formed dispersively and in a random direction on a surface thereof, and the total area of the ridges is not more than 50% of a whole surface area of the anti-glare film. The ridge may have an average height of 0.05 to 10 μm and an average width of 0.1 to 30 μm. The ridge may have a depression extending along a longitudinal direction thereof.

A light emitting device, which can be efficiently manufactured and maintain a stable light emitting property for a long period, is provided. The light emitting device comprises a first resin forming body including a periphery that forms a recess to house a light emitting element and a bottom that forms a bottom portion of the recess, and a second resin forming body which covers the light emitting element. The first resin forming body is composed of a thermosetting epoxy resin composite whose essential component is an epoxy resin. The bottom covers surfaces of lead frames excluding mounting regions of the light emitting element and wires. A thickness of the bottom is formed thinner than a thickness from the surface of the lead frames to a leading end of the light emitting element.

It is an object of the present invention to provide a liquid crystal display panel having a high contrast ratio in a front direction.A liquid crystal panel according to an embodiment of the present invention includes: a liquid crystal cell; a first polarizing plate placed on one side of the liquid crystal cell; a second polarizing plate placed on the other side of the liquid crystal cell; and a retardation layer placed between the liquid crystal cell and the second polarizing plate. A refractive index ellipsoid of the retardation layer exhibits a relationship of n≧ny>nz; and a light transmittance (T2) of the second polarizing plate is larger than a light transmittance (T1) of the first polarizing plate. Such a liquid crystal panel has a remarkably higher contrast ratio in a front direction than that of a conventional liquid crystal panel (for example, a liquid crystal panel in which the light transmittances of two polarizing plates placed on both sides of a liquid crystal cell are the same), and shows excellent display properties.

Disclosed is a core-shell microparticle (10) which is produced by heating a mixture of a crosslinked microparticle (11) having an alkoxyamine group (12) and a monomer to 100 to 180° C. to cause graft polymerization. The crosslinked microparticle (11) is produced by allowing a seed particle to absorb a monomer mixture comprising 15 to 99% by mass of a crosslinkable monomer and 1 to 85% by weight of a monomer having an alkoxyamine group, and then adding a polymerization initiator to the resulting product to cause the polymerization of the monomer mixture.
