  • Process for forming a coating on a substrate
    Patent number: 5462770
    Abstract: The present invention provides a low viscosity curable resin composition and coating composition containing the same which has a decreased solvent content. The coating composition provides a cured film having not only excellent acid resistance but also good weather resistance and mar resistance without an adverse effect to the environment. The curable resin composition comprises (a) a hydroxyl and carboxyl group containing silicone polymer, (b) a carboxyl and carboxylate group containing polymer, and (c) a hydroxyl and epoxy group containing polymer.
