Abstract 1. AN ACRYLIC ORGANOSOL COATING COMPOSITION CONSISTING ESSENTIALLY OF: ABOUT 10-60% BY WEIGHT OF FILM-FORMING CONSTITUENTS DISPERSED IN ORGANIC LIQUID WHEREIN THE FILM-FORMING CONSTITUENTS CONSIST ESSENTIALLY OF A GRAFT COPOLYMER COMPRISING A BACKBONE (A) AND ONE OR MORE SIDE CHAINS (B), THE BACKBONE (A) BEING A POLYMERIC SEGMENT OF UNITS (A) AND UP TO 15% BY WEIGHT OF UNITS (B), SAID (B) UNITS PROVIDING AVAILABLE ACTIVE GRAFTING SITES FOR GRAFT POLYMERIZATION, AND EACH SIDE CHAIN (B) ABOVE BEING A POLYMERIC SEGMENT, (A) AND (B) BEING DIFFERENT FROM EACH OTHER, AND (A) AND 8B) EACH BEING COMPOSED OF AT LEAST 50% BY WEIGHT OF UNITS OF ESTERS OF ACRYLIC, METHACRYLIC ACID AND/OR ETHACRYLIC ACID, PROVIDED THAT SUCH THAT EITHER (A) OR (B) IF PREPARED AS A SEPARATE POLYMERIC ENTITY, IS SUBSTANTIALLY SOLUBLE IN SAID ORGANIC LIQUID, WHEREAS, THE OTHER OF (A) OR (B), IF PREPARED AS A SEPARATE POLYMERIC ENTITY, IS SUBSTANTIALLY INSOLUBLE IN THE SAME ORGANIC LIQUID; WHEREIN THE (A) MONOMER UNITS OF THE (A) SEGMENT CONSISTS OF METHYL METHACRYLATE AND THE (B) MONOMER UNITS OF THE (A) SEGMENT CONSIST OF ALLYL METHACRYLATE AND THE MONOMER UNITS OF THE (B) SEGMENT ARE SELECTED FROM THE GROUP CONSISTING OF 2-ETHYLHEXYL ACRYLATE OR ACRYLONITRILE; AND 1-28% BY WEIGHT BASED ON THE TOTAL WEIGHT OF THE COATING COMPOSITION, OF A PLASTICIZER CONSISTING OF THE ESTERIFICATION PRODUCT OF ABOUT 30 TO 35 MOLE PERCENT ADIPIC ACID, ABOUT 43 TO 48 MOLE PERCENT OF NEOPENTYL GLYCOL AND ABOUT 20 TO 25 MOLE PERCENT OF BENZOIC ACID, WHEREIN THE PLASTICIZER HAS A HYDROXYL NUMBER OF NOT GREATER THAN 40.
AN ACRYLIC ORGANOSOL COATING COMPOSITION CONSISTING ESSENTIALLY OF: ABOUT 10-60% BY WEIGHT OF FILM-FORMING CONSTITUENTS DISPERSED IN ORGANIC LIQUID WHEREIN THE FILM-FORMING CONSTITUENTS CONSIST ESSENTIALLY OF A GRAFT COPOLYMER COMPRISING A BACKBONE (A) AND ONE OR MORE SIDE CHAINS (B), THE BACKBONE (A) BEING A POLYMERIC SEGMENT OF UNITS (A) AND UP TO 15% BY WEIGHT OF UNITS (B), SAID (B) UNITS PROVIDING AVAILABLE ACTIVE GRAFTING SITES FOR GRAFT POLYMERIZATION, AND EACH SIDE CHAIN (B) ABOVE BEING A POLYMERIC SEGMENT, (A) AND (B) BEING DIFFERENT FROM EACH OTHER, AND (A) AND 8B) EACH BEING COMPOSED OF AT LEAST 50% BY WEIGHT OF UNITS OF ESTERS OF ACRYLIC, METHACRYLIC ACID AND/OR ETHACRYLIC ACID, PROVIDED THAT SUCH THAT EITHER (A) OR (B) IF PREPARED AS A SEPARATE POLYMERIC ENTITY, IS SUBSTANTIALLY SOLUBLE IN SAID ORGANIC LIQUID, WHEREAS, THE OTHER OF (A) OR (B), IF PREPARED AS A SEPARATE POLYMERIC ENTITY, IS SUBSTANTIALLY INSOLUBLE IN THE SAME ORGANIC LIQUID; WHEREIN THE (A) MONOMER UNITS OF THE (A) SEGMENT CONSISTS OF METHYL METHACRYLATE AND THE (B) MONOMER UNITS OF THE (A) SEGMENT CONSIST OF ALLYL METHACRYLATE AND THE MONOMER UNITS OF THE (B) SEGMENT ARE SELECTED FROM THE GROUP CONSISTING OF 2-ETHYLHEXYL ACRYLATE OR ACRYLONITRILE; AND 1-28% BY WEIGHT BASED ON THE TOTAL WEIGHT OF THE COATING COMPOSITION, OF A PLASTICIZER CONSISTING OF THE ESTERIFICATION PRODUCT OF ABOUT 30 TO 35 MOLE PERCENT ADIPIC ACID, ABOUT 43 TO 48 MOLE PERCENT OF NEOPENTYL GLYCOL AND ABOUT 20 TO 25 MOLE PERCENT OF BENZOIC ACID, WHEREIN THE PLASTICIZER HAS A HYDROXYL NUMBER OF NOT GREATER THAN 40.
