Abstract
A pigment composition comprising pigment and an amido phthalocyanine compound having the general formula I: MPc—(CONR1R2)n I wherein which Pc is a phthalocyanine ring which is optionally further substituted by up to an average of one chlorine or bromine atom or of a sulphonic acid; M is hydrogen or a metal such as Mg, Al, Ni, Fe, Zn, Pb, Sn or Cu: n is a number ranging from 0.1 to 4.0; R1 and R2 are independently selected from hydrogen, C1-C20 alkyl, C5-C12 cycloalkyl, C7-C12 aralkyl, C6-C10 aryl, C4-C6 alkyl amino alkyl, C2-C20 aliphatic amine, C2-C20 aliphatic amine acid salt, C2-C20 alcohol, polyoxyalkylene, polyoxyalkylene amine.
Claims17
A pigment composition comprising a tinctorially effective amount of a phthalocyanine pigment and an effective flow control or heat stabilizing amount of a compound of formula (I)
- MPc—(CONR1R2)n I
- wherein
- Pc is a phthalocyanine ring which is optionally further substituted by up to an average of one chlorine or bromine atom or of a sulphonic acid;
- M is hydrogen or a metal;
- n is a number ranging from 0.1 to 4.0;
- R1 and R2 are independently from one another hydrogen, C1-C20 alkyl, C5-C12 cycloalkyl, C7-C12 aralkyl, C6-C10 aryl, aliphatic amino-C2-C20alkyl, or an acid salt thereof, hydroxy-C2-C20alkyl or a polyoxyalkylenyl or aminopolyoxyalkenyl group, with the proviso that when R1 is hydrogen, R2 is not hydrogen or C1-C12alkyl.
