[1] an air containing a structural unit derived from a vinyl monomer (c1a) containing a pigment (A), a non-aqueous solvent (B), and a reactive functional group, and a vinyl monomer (c1b) containing a nitrogen atom A polymer obtained by reacting a copolymer ((c1) component) with a poly (meth) acrylate having a functional group capable of reacting with a reactive functional group of the component (c1) and / or polystyrene (component (c2)) at one end ( Process (I) obtained by making non-aqueous pigment dispersion composition containing C), and [2] vinyl monomer (c1b) and (c1a) react, and manufacturing the copolymer containing the structural unit derived from the said vinyl monomer. It is a manufacturing method of the polymer for non-aqueous pigment dispersion which has the process (II) which makes a copolymer and (c2) component react, and produces the graft copolymer which said (c2) component graft-bonded to the said copolymer. |
