  • High-solids coating composition
    Patent number: 5753756
    Abstract: A coating composition useful for a finish for automobiles and trucks in which the film-forming binder comprises a hydroxy-functional (meth)acrylate copolymer derived from comonomers comprising a alkyl-substituted cycloaliphatic (meth)acrylic comonomer and/or alkyl-substituted aromatic vinyl comonomer is disclosed. The composition further comprises a structured multi-hydroxyl oligoester and a crosslinking agent. The composition is characterized by an improved balance of viscosity and dry time.
