Zusammenfassung:PROBLEM TO BE SOLVED: To provide a coloring matter excellent in light resistance, migration resistance and solvent resistance, and useful as e.g. a coloring matter for an inkjet printer ink or for a color toner. SOLUTION: This polymerizable coloring matter monomer contains a quaternary ammonium cation having a terminal double bond, represented by general formula (1) (wherein X is -CH2-, -COO-, or -CONH-; R1is a hydrogen atom or a methyl group; R2, R3and R4are each independently a 1-10C alkyl group or a benzyl group; and n is 0 to 8), and it has an absorption peak at 400 to 450 nm. This polymer is obtained from the monomer. COPYRIGHT: (C)2005,JPO&NCIPI
