ABSTRACT:
An acrylic resin composition for use in high solids paints which consists essentially of an acrylic copolymer having a number average molecular weight of 500 to 5000 and being prepared by subjecting a mixture of 30 to 88 weight % of an alkyl (meth)acrylate, 2 to 60 weight % of 2,4-diphenyl-4-methyl-1-pentene, 10 to 40 weight % of a hydroxy bearing ethylenically unsaturated monomer, 0 to 10 weight % of an ethylenic unsaturated acid and 0 to 30 weight % of other copolymerizable monomer(s) to a polymerization with one or more radical initiators. Such high solids paint containing such copolymers can produce coatings with excellent weather resistance, water resistance, scratch resistance and good appearance.
