Abstract

Abstract A phthalocyanine pigment composition comprising a phthalocyanine pigment and a sulphonated phthalocyanine derivative formed from sulphonated phthalocyanine dyestuffs having the formula: ##STR1## AND A SUFFICIENT QUANTITY OF DEHYDROABIETYLAMINE HAVING THE FORMULA ##STR2## to substantially neutralize the free sulphonic acid groups, wherein R represents a C 1 -C 22 cyclic or acyclic alkyl group, aryl, aralkyl group or a dehydroabietylamine residue; and R 1 represents hydrogen or a C 1 -C 22 cyclic or acyclic alkyl group, an aryl or an aralkyl group; the alkyl, cycloalkyl, aryl or aralkyl groups, R and R 1 may be optionally substituted with one or more hydroxyl groups; x is from 1 to 4, y is 0 or from 1 to 3 and the sum of x + y is from 1 to 4 gives printing inks and paint media having improved tinctorial strength, gloss and especially improved rheological properties.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 147 words
A phthalocyanine pigment composition comprising a phthalocyanine pigment and a sulphonated phthalocyanine derivative formed from sulphonated phthalocyanine dyestuffs having the formula: ##STR9##and a sufficient quantity of dehydroabietylamine having the formula ##STR10##to substantially neutralise the free sulphonic acid groups, wherein R represents a C 1 - C 22 cyclic or acyclic alkyl group, aryl, aralkyl group or a dehydroabietylamine residue; and R 1 represents hydrogen or a C 1 - C 22 cyclic or acyclic alkyl group, an aryl or an aralkyl group; the alkyl, cycloalkyl, aryl or aralkyl groups, R and R 1 may be optionally substituted with one or more hydroxyl groups; x is from 1 to 4, y is 0 or from 1 to 3 and the sum of x + y is from 1 to 4, and wherein the ratio of phthalocyanine pigment to sulphonated phthalocyanine dyestuff is from 80:20 to 99:1 by weight.
Claim 2
Dependent Claim 147 words
A phthalocyanine pigment composition comprising a phthalocyanine pigment and a sulphonated phthalocyanine derivative formed from sulphonated phthalocyanine dyestuffs having the formula: ##STR9##and a sufficient quantity of dehydroabietylamine having the formula ##STR10##to substantially neutralise the free sulphonic acid groups, wherein R represents a C 1 - C 22 cyclic or acyclic alkyl group, aryl, aralkyl group or a dehydroabietylamine residue; and R 1 represents hydrogen or a C 1 - C 22 cyclic or acyclic alkyl group, an aryl or an aralkyl group; the alkyl, cycloalkyl, aryl or aralkyl groups, R and R 1 may be optionally substituted with one or more hydroxyl groups; x is from 1 to 4, y is 0 or from 1 to 3 and the sum of x + y is from 1 to 4, and wherein the ratio of phthalocyanine pigment to sulphonated phthalocyanine dyestuff is from 80:20 to 99:1 by weight.
Claim 3
Dependent Claim 17 words
A pigment composition as claimed in claim 1, in which the sulphonated phthalocyanine is a copper phthalocyanine.
Claim 4
Dependent Claim 16 words
A pigment composition as claimed in claim 1 in which the pigment is a copper phthalocyanine.
Claim 5
Dependent Claim 17 words
A pigment composition as claimed in claim 1, in which the ratio is from 90:10 to 96:4.
Claim 6
Dependent Claim 21 words
A pigment composition as claimed in claim 1, in which x is 1 - 2.5 and y is 0 - 3.
Claim 7
Dependent Claim 29 words
A pigment composition as claimed in claim 1, which also contains a urethane compound having two or more urethane groups and contains no significant proportion of basic amino groups.
