Abstract

Abstract 1. IN A PROCESS FOR PREPARING A COLORED POLYURETHANE LEATER BY REACTING A POLYISOCYANATE WITH A POLYOL OR A POLYURETHANE, THE IMPROVEMENT WHICH COMPRISES REACTING SAID POLYISOCYANATE WITH A COPPER PHTHALOCYANINE DYE HAVIN THE FORMULA (CU-PC(-SO2-N(-R)-R1)X-(SO3(-)-NH(+)(-R2)-R3)Y) (N<(-(4,7-DI(Y-)-ISOINDOL-1,3-YLENE)=N-(4,7-DI(Y-)- ISOINDOL-1,3-YLENE)-N=(4,7-DI(Y-)-ISOINDOL-1,3-YLENE)- N=(4,7-DI(Y-)-ISOINDOL-1,3-YLENE)=) CU)(-SO2-N(-R)-R1)X (-SO3(-)-NH(+)(-R2)-R3)Y WHEREIN Y IS HYDROGEN OR CHLORINE; R REPRESENTS HYDROGEN, ALKYL OR HYDROXYALKYL, R1 REPRESENTS -A-X1 -(PHENYLENE)-B-X2 -(PHENYLENE)-D-B-X2 -(PHENYLENE)-D-N(-X3)-B-X2 -(PHENYLENE)-N(-X3)-D-B-X2 OR -(PHENYLENE)-X4 WHEREIN A REPRESENTS ALKYLENE CONNECTED TO X1, X1 REPRESENTS HYDROXYL, AMINO OR ALKYLAMINO, B REPRESENTS AN ALKYLENE GROUP CONNECTED TO X2, X2 REPRESENTS HYDROXYL; D REPRESENTS -SO2- OR -CO-, X3 REPRESENTS HYDROGEN, ALKYL OR HYDROXYALKYL, X4 REPRESENTS AMINO, ALKYLAMINO OR HYDROXYL SUBSTITUTED ALKYL AMINO, R2 REPRESENTS HYDROGEN OR ALKYL, R3 REPRESENTS ALKYL OR ALKYLAMINO; X REPRESENTS AN INTEGE R FROM 1-4; Y REPRESENTS 0 OR AN INTEGER FROM 1-3 AND X+Y IS 1,2,3, OR 4.
