Method for providing a color image by ink-jet printing

Claim 1

A method for providing a color image by ink-jet printing using an aqueous ink composition containing a yellow dye, an aqueous ink composition containing a magenta dye and an aqueous ink composition containing a cyan dye, said yellow dye being selected from among the compounds of the formula (I), said magenta dye being selected from among the compounds of the formula (II), and said cyan dye being selected from among the compounds of the formula (III): ##STR13## wherein R 1 is an amino group; R 2 is a phenyl group, a substituted phenyl group, a (C 1 -C 4 ) alkyl group or a substituted (C 1 -C 4 ) alkyl group; R 3 is a (C 1 -C 4 ) alkyl group, a phenyl group, a substituted phenyl group, a cyano group, a hydroxyl group, an alkoxy group, an amino group, an acylamino group, an anilino group, a ureido group, an alkoxycarbonyl group or a carbamoyl group; X is a chlorine atom; n is 1, 2 or 3; and m is 1, 2 or 3, the number of sulfo groups in the formula (I) is 1 to 3, provided that sulfo groups in the formula (I) may be an alkali metal salt or an organic amine salt; ##STR14## wherein R 4 is a cyano group, an alkylsulfonyl group, an arylsulfonyl group, a trichloromethyl group or a trifluoromethyl group; R 5 is a hydrogen atom, an alkyl group, an acyl group, an alkylcarbamoyl group or an arylcarbamoyl group; and p is 1 or 2, provided that sulfo groups in the formula (II) may be an alkali metal salt or an organic amine salt; and ##STR15## wherein q is 1 to 4, provided that sulfo groups in the formula (III) may be an alkali metal salt or an organic amine salt.

Claim 2

A method for providing a color image by ink-jet printing using an aqueous ink composition containing a yellow dye, an aqueous ink composition containing a magenta dye and an aqueous ink composition containing a cyan dye, said yellow dye being selected from among the compounds of the formula (I), said magenta dye being selected from among the compounds of the formula (II), and said cyan dye being selected from among the compounds of the formula (III): ##STR13## wherein R 1 is an amino group; R 2 is a phenyl group, a substituted phenyl group, a (C 1 -C 4 ) alkyl group or a substituted (C 1 -C 4 ) alkyl group; R 3 is a (C 1 -C 4 ) alkyl group, a phenyl group, a substituted phenyl group, a cyano group, a hydroxyl group, an alkoxy group, an amino group, an acylamino group, an anilino group, a ureido group, an alkoxycarbonyl group or a carbamoyl group; X is a chlorine atom; n is 1, 2 or 3; and m is 1, 2 or 3, the number of sulfo groups in the formula (I) is 1 to 3, provided that sulfo groups in the formula (I) may be an alkali metal salt or an organic amine salt; ##STR14## wherein R 4 is a cyano group, an alkylsulfonyl group, an arylsulfonyl group, a trichloromethyl group or a trifluoromethyl group; R 5 is a hydrogen atom, an alkyl group, an acyl group, an alkylcarbamoyl group or an arylcarbamoyl group; and p is 1 or 2, provided that sulfo groups in the formula (II) may be an alkali metal salt or an organic amine salt; and ##STR15## wherein q is 1 to 4, provided that sulfo groups in the formula (III) may be an alkali metal salt or an organic amine salt.
