A pigment composition for polymerized toner synthesized from a diazo component yielded by diazotizing a 2-methoxy-4-nitroaniline and/or 4-methoxy-2-nitroaniline, and a coupler component comprising 60 to 98.5% by mole of acetoacetoorthoanisidide, 0.5 to 20% by mole of a compound represented by CH3COCH2CONH-X (1) and 1.0 to 20% by mole of a compound represented by CH3COCH2CONH-Y (2) wherein X represents a phenyl group having a substituent as a polar group selected from the group consisting of carboxylic acid groups, sulfonic acid groups and metal salts thereof, the number of polar group is 1 to 4, when the plural polar groups are selected, the groups may be the same or different, Y represents a phenyl group having an alkoxy group other than orthomethoxy, the alkoxy group having 1 to 4 carbon atoms.
