PURPOSE: To provide a coating composition for base coating, containing a specific acrylic graft copolymer and a crosslinking agent, having excellent compatibility, storage stability and the appearance of the coating film, and useful as the top-coating of automobile, etc. n CONSTITUTION: The objective composition can be produced by compounding (A) an acrylic graft copolymer obtained by the copolymerization of (i) a cellulose derivative having a copolymerizable double bond and obtained by the reaction of a cellulose derivative (e.g. cellulose acetate butyrate, etc.) with a mono or diester of maleic acid or fumaric acid and (ii) a polymerizable monomer (e.g. hydroxyethyl acrylate, acrylic acid, styrene, etc.) and (B) a crosslinking agent (e.g. alkoxylated melamine formaldehyde condensate). The ratio of the copolymer A to the amino resin is 60/40W90/10. n COPYRIGHT: (C)1985,JPO&Japio |
