Abstract: Microporous sheets coated with substantially solvent-free, water-based coating compositions are disclosed. The coating compositions may comprise film-forming resins such as polyurethanes, acrylics and polyesters, and may further comprise pigments, crosslinkers, standard additives and the like. The coated microporous sheets exhibit favorable visual and mechanical properties, including high levels of elongation. The coated microporous sheets of the present invention may be applied to substrates by techniques such as injection molding and compression molding. The ability of the coated microporous sheets to withstand substantial elongation permits their use in high draw, in-mold applications.
