Abstract
Abstract This invention is concerned with autoxidizable coating compositions which contain (1) a member of the group consisting of an organic polyisocyanate, an isocyanate-modified drying oil, and a uralkyd; (2) at least one non-volatile reactive liquid monomer selected from the group consisting of dicyclopentenyloxyalkyl acrylate and dicyclopentenyloxyalkyl methacrylate; and (3) an effective amount of a polyvalent metal-containing complex or salt that catalyzes the curing of (1) and (2). Use of the non-volatile reactive liquid component enables the production of coating compositions having high application solids content and yet having suitable viscosity for efficient handling. The reduced volatile component improves the environmental aspects of preparing and using the coating compositions while the combining of these materials in the film results in enhancement of the film properties without detriment to the qualities normally desired and attained with the polyurethane type of coating composition.
