摘要:
A water-based ink for ink-jet printing, comprising colored particles containing: (a) a core particle having a colorant; and (b) a shell having a resin and encapsulating the core particle, wherein the resin comprises a monomer unit having a hydroxyl group in an amount of 0.1 to 50 weight % based on the total weight of the shell.
摘要:
A water-based ink comprising water and at least one kind of colored particles selected from the group consisting of: (a) colored particles comprising a polymer containing a colorant; (b) colored particles comprising a core forming colorant and a shell forming polymer which encapsulates the core forming colorant; and (c) particles comprising a core forming polymer containing a colorant and a shell forming polymer which encapsulates the core forming polymer, wherein the initial elution value of the colorant of the colored particles being measured in a colorant dissolving solvent is at most 10% of the maximum elution value.
摘要:
A water-based ink containing colored microparticles containing a dye and a polymer dispersed in water, wherein a total amount of a monomer remaining in the colored microparticles is less than or equal to 5000 ppm based on the total weight of the water-based ink.
摘要:
A dispersion of colored particles is disclosed. The dispersion is prepared by emulsifying a mixture comprising a colorant and polymer, employing a reactive emulsifier, and subsequently copolymerizing the resulting mixture, employing polymerizable monomer. An ink employing the dispersion is also disclosed.

摘要:
A wave length conversion device of fibre type having a nonlinear optical material as a core which is consist of a single crystal of 2-methoxy-5-nitrophenol is disclosed. When the principal absorption axis of the single crystal is perpendicular to a center axis of the fibre (the material for cladding the core), the efficiency of the conversion the wave length is the highest.
摘要:
A surface plasmon-field enhanced fluorescence spectroscopy [SPFS] sensor chip may include a transparent support, a metal thin film formed on one surface of the transparent support, a self-assembled monolayer [SAM] formed on a surface of the metal thin film, said surface not being in contact with the transparent support, a solid phase layer formed on a surface of the SAM and having a three-dimensional structure, said surface not being in contact with the metal thin film, and a ligand immobilized in the solid phase layer. A fluctuation ratio represented by the following formula is not less than 0% but not more than 30%: {half-width (α)−half-width (β)}/half-width (β)×100.
