摘要:
A process for producing resin particles includes a step in which a polymerizable mixture including a polymerizable monomer including at least one of a styrene-based monomer and a (meth)acrylic-based monomer, and a polymerization initiator is absorbed into seed particles in an aqueous medium, without using a dispersant, in the presence of an anionic surfactant not having a polyoxyethylene chain but having an alkyl group; and a step in which the polymerizable monomer is polymerized in an aqueous medium, without using a dispersant, in the presence of an anionic surfactant having a polyoxyethylene chain to thereby obtain resin particles. The resin particles include a resin derived from a polymerizable monomer including at least one of a styrene-based monomer and a (meth)acrylic-based monomer. The proportion by number of particles having a particle diameter in the range of from 80 to 120% of the volume-average particle diameter is 85% or more.

The invention provides non-spherical resin particles with a novel shape capable of improving light diffusion, adhesion, oil absorption, and other properties, as well as a manufacturing method and use of the particles. Each non-spherical resin particle includes a concave portion and a convex portion formed in the concave portion, wherein the convex portion has a quasi-spherical surface. The method of manufacturing non-spherical resin particles involves a step of polymerizing 100 parts by weight of a first monomer mixture containing 77 to 99.99 parts by weight of a branched alkyl methacrylate, 0.01 to 3 parts by weight of a polyfunctional monomer, and 0 to 20 parts by weight of a monofunctional (meth)acrylate which is not a branched alkyl methacrylate, in the presence of 0.1 to 0.9 parts by weight of a chain transfer agent and 0 to 100 parts by weight of a (meth)acrylate polymer, to obtain resin particles.

The present invention is to provide a retardation film having excellent durability against temperature change or the like and a production method of the retardation film. Particularly, the present invention is to provide a retardation film which realizes both reverse wavelength dispersion and durability and a production method of the retardation film. This is achieved by a retardation film including: a component (A) which is specific cellulose acylate; and a component (B) which is cellulose acylate or cellulose ether having a molecular weight different from a molecular weight of the component (A) and whose residual degree of hydroxyl group is 0.30 or more.

An adhesive composition of the present invention comprises (A) a conjugated diene polymer having a weight-average molecular weight of 500 to 100,000 and (B) an electron pair-donating basic compound; or comprises (A) a conjugated diene polymer having a weight-average molecular weight of 500 to 100,000, (C) a compound having in its molecule three or more functional groups selected from the group consisting of acryloyloxy group, methacryloyloxy group and groups represented by the following formula I: wherein R1, R2 and m are the same as defined in the specification, and (D) a compound having in its molecule one or two functional groups selected from the group consisting of acryloyloxy group and methacryloyloxy group. At least a part of the surface of an adherend is coated with the adhesive composition to form an adhesive layer. After optionally irradiating the adhesive layer with ultraviolet light or radiation, the vulcanization is preformed while bringing an unvulcanized rubber into press-contact with the adhesive layer, thereby attaining a strong adhesion between the rubber and the adherend. The rubber/adherend composite thus produced is suitably used for the production of rubber-reinforcing materials and rubber articles.

An ink jet recording apparatus has means for heating a recording medium guide member disposed near the ink recording area by a recording head for discharging ink, and means for changing the rate of heat imparted to the unit length of the recording medium with respect to the direction of conveyance thereof by the heating means in conformity with a parameter changing the environmental condition of the ink recording area.
摘要:
A infrared/visible integrated imaging apparatus having a video signal mixing device for superimposing a visible video signal upon an infrared video signal. The mixing device has a discriminating circuit setting electrical discrimination between an infrared video signal having a level higher than a predetermined black level and having a lower than the predetermined black level. The visible video signal simultaneously output with the infrared video signal having the level higher than a predetermined black level is practically cut off with a visible video signal selecting circuit. The partially cut off video signal is then superimposed on the thermal video signal for display. The level of each of the two video signals is independently controllable.
