摘要： A process is provided for producing a colored fine particulate composition by dissolving or dispersing a coloring matter or a coloring matter and charge control agent in a condensation-polymerized resin component and forming the resultant resin composition into fine particles. The coloring matter or the coloring matter and charge control agent are added to a raw material component for the production of the resin component, or to the resin component in a period from initiation to completion of polymerization of the resin component or while the resin component is in a molten state subsequent to the completion of the polymerization, whereby the coloring matter or the coloring matter and charge control agent are dissolved or dispersed in the resulting resin component. A colored composition obtained subsequent to the dissolution or the dispersion is cooled. The colored composition so cooled is then formed into fine particles.

摘要： A graft copolymer is formed by copolymerization of (A) a macromonomer and (B) a monomer. The macromonomer (A) is a polymer of (a) an ester monomer between an addition-polymerizable, unsaturated carboxylic acid and an aliphatic alcohol and (b) an addition-polymerizable monomer having an acidic group. The polymer contains an addition-polymerizable group at an end thereof, and has an acid value of from 100 to 300. The monomer (B) is an addition-polymerizable monomer. Units of the macromonomer (A) amount to from 20 to 50 wt.% of the whole graft copolymer, and units of the monomer (B) amount to from 50 to 80 wt.% of the whole graft copolymer.
