Abstract
Abstract Copper phthalocyanine derivatives of the formula ##STR1## or mixtures thereof wherein CuPc is optionally substituted copper phthalocyanine, n is a value from 1 to 4, X is hydrogen, 1-4 C alkyl, 1-4 C alkoxy or halogen, and R is linear or branched alkyl of 1 to 22 C-atoms which may be substituted with one or more alkoxy, dialkylamino or alkylthio, the alkyls having 1 to 22 C-atoms, or arylalkyl, the alkyl having 1 to 4 C-atoms and the aryl being optionally substituted by one or more non-water solubilizing groups, which incorporated into a phthalocyanine pigment, provide excellent flocculation resistance in paint and printing ink media.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
135 words
A copper phthalocyanine derivative having the formula ##STR4## or a mixture thereof, wherein CuPc represents the residue of a copper phthalocyanine molecule, n is 1-4, X is hydrogen, C 1-4 alkyl, C 1-4 alkoxy or halo, and R is straight or branched chain alkyl of 1-22 carbon atoms, which is unsubstituted or substituted by one or more alkoxy, dialkylamino or alkylthio, the alkyl groups of which are straight or branched chain alkyl of 1-22 carbon atoms, and the alkyl groups in dialkylamino moiety are the same or different; or R is arylalkyl having 1-4 carbon atoms in the alkyl moiety thereof and the aryl moiety thereof being unsubstituted or substituted by one or more alkyl, alkoxy, carboxyalkyl or alkylcarbamoyl each having from 1-4 carbon atoms in the alkyl moiety thereof, arylcarboxyarylamido, arylcarbamoyl, nitro or halo.
Claim 2
Dependent Claim
