Abstract
Dispersants for pigments as well as dispersions of pigments containing them, and compositions such as inks and coatings containing them are described. The dispersants are the reaction product of a dialkylsuccinyl succinate and an amine.
Claims32
A pigment dispersant which is the reaction product of a dialkylsuccinyl succinate and one or more amines of which at least one is a polymeric amine having a number average molecular weight of at least about 200.
A composition comprising the combination of a pigment with a pigment dispersant which is the reaction product of a dialkylsuccinyl succinate and one or more amines of which at least one is a polymeric amine having a number average molecular weight of at least about 200.
A composition comprising a pigment, an ink or coating carrier and a pigment dispersant which is the reaction product of a dialkylsuccinyl succinate and one or more amines of which at least one is a polymeric amine having a number average molecular weight of at least about 200.
A substrate having on at least a portion of it's surface, a composition comprising the combination of a pigment with a pigment dispersant which is the reaction product of a di(lower alkyl)succinyl succinate and one or more amines of which at least one is a polymeric amine having a number average molecular weight of at least about 200 and is an amine-terminated poly(alkylene oxide).
