Abstract:
An ink for ink-jet recording which comprises a color composition prepared by dispersing, in a water-based medium, coloring particulates that contain an oil-soluble dye and a vinyl polymer which is obtained through copolymerization of a vinyl monomer A and a vinyl monomer B that differs from the vinyl monomer A, wherein the vinyl monomer A is represented by general formula (I) as follows: in which in general formula (I): R11 represents a hydrogen atom, an alkyl group having from 1 to 4 carbon atoms, or a chlorine atom; L1 represents â€”Oâ€”, â€”COOâ€”, â€”OCOâ€”, â€”CONR12â€”, or a substituted or unsubstituted phenylene group; X1 represents â€”CH2â€”, â€”CHR13â€”, â€”CR13R14â€”, â€”CH2CH2Oâ€”, â€”CH2CHR13Oâ€”, â€”CHR13CH2Oâ€”, a substituted or unsubstituted arylene group, or a substituted or unsubstituted cycloalkylene group; q is 2 or more if L1 is â€”COOâ€”, and q is 1 or more in other cases; L2 represents â€”Oâ€”, â€”COâ€”, â€”COOâ€”, â€”OCOâ€”, â€”CONR12â€”, â€”NR12COâ€”, â€”NR2COOâ€”, or â€”NR12CONR15â€”; r is 0 or 1; X2 represents â€”CH2â€”, â€”CH2CHR13â€”, â€”CHR13CH2â€”, a substituted or unsubstituted arylene group, or a substituted or unsubstituted cycloalkylene group; s is from 0 to 18; R12 and R15 each independently represents a hydrogen atom, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aryl group; and R13 and R14 each independently represents a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group.
