ABSTRACT:
An in-mold lacquer coating, and a process for utilizing the same, for producing a polyurethane-based molded article. The lacquer coating is mold-releasable without the aid of an external mold release agent, is re-coatable after de-molding without additional surface preparation, and comprising a mixture of a pre-reacted aliphatic polyurethane resin, a technically simple silicon resin mold-release agent, and an aromatic, acetate and alcoholic solvent system that is incompatible with the silicon resin and that has constituents with specific gravities less than the silicon resin and with varying rates of evaporation such that the ratio of aromatic to alcoholic solvents decreases as the solvent system evaporates.
