Abstract:
A method for imparting flow-and-leveling properties to inks and paints, comprising the step of:adding a copolymer having a number-average molecular weight of from 1,000 to 60,000 which is obtained by copolymerizing 2-50% by weight of monomer (A) silicone oil having acryloyloxy group or methacryloyloxy group, represented by a general formula (I) â€ƒin which R1 stands for hydrogen or methyl, R2 stands for C1-C10 alkylene, R3 stand for C1-C4 alkyl, and n stands for an integer of 5-100 with 50-98% by weight of monomer (B) an acrylic acid ester or methacrylic acid ester represented by a general formula (II) â€ƒin which R4 stands for hydrogen or methyl, and R5 stands for C1-C12 alkyl and/or monomer (C) an acrylic acid ester or methacrylic acid ester represented by a general formula (III) â€ƒin which R6 stands for hydrogen or methyl, R7 stands for hydrogen or C1-C18 alkyl, n stands for an integer of 2-4 and m stands for an integer of 1-50 to inks and paints.
