PHTHALOCYANINES AND THEIR USE IN INK-JET PRINTING

A mixture of dyes of Formula (1) and salts thereof: wherein: M is 2H, Si, a metal, an oxymetal group, a hydroxymetal group or a halometal group; Pc represents a phthalocyanine nucleus of formula R1 and R2 independently are H or optionally substituted C1-4

NOVEL PORPHYRAZINE DYE, INK, INK SET, AND COLORED MATERIAL

The present invention relates to a porphyrazine coloring matter represented by the following formula (1): (wherein, A, B, C and D independently represent a 6-membered ring having aromaticity, at least one or more of them are benzene rings and at least one or more of them contain nitrogen-containing heteroaromatic rings; E represents alkylene, X is a substituted anilino group and have at least one or more of sulfo group, carboxy group and phosphono group as a substituent, Y represents a hydroxy group or an amino group, b is respectively 0 to 2.9, c is 0.1 to 3, and the sum of b and c is 1 to 3) in free acid form, which is suitable for inkjet recording because it has good hue as a cyan ink, is excellent in light fastness, ozone fastness and moisture fastness, and does not cause bronzing phenomenon.

PHTHALOCYANINE DYE AND USE THEREOF FOR INK-JET PRINTING

The present invention relates to a phthalocyanine colorant characterized in that it has, as substituents, at least one unsubstituted sulfamoyl group and at least one substituted sulfamoyl group, the total number of these groups being 2 to 4, the substituent on the substituted sulfamoyl group has a substituted triazinyl group bonded thereto through a crosslinking group, and the unsubstituted sulfamoyl group and the substituted sulfamoyl group are bonded to the phthalocyanine ring at the β-position. Said phthalocyanine colorant is suitable for use in an ink, especially a cyan ink, for an ink-jet printer. A printed matter obtained by printing with said ink is excellent in light fastness, ozone fastness and moisture fastness.
