  • Patent number: 5000809
    Abstract: A process for forming a composite that is useful as an exterior vehicle part in which a layer of a coating composition is applied to a flexible smooth glossy polymeric carrier sheet and dried and laminated under heat and pressure to a flexible polymeric substrate to form a laminate, the carrier sheet is removed and the laminate is thermoformed into a three dimensional structure and a rigid thermoformable plastic is adhered to the thermoformed laminate to form the composite; the coating compsition used in the process that forms the exterior finish on the composite has a film forming binder which is in an organic liquid carrier is of a polyesterurethane and a multifunctional crosslinking agent of an epoxy compound or an organic polyisocyanate; whereinthe polyesterurethane is formed by reacting a hydroxy functional polyester with a hydroxy containing carboxylic acid and an organic polyisocyanate.
