Abstract
A flexible paint-coated film which has a basecoat-clearcoat appearance and good mar-resistance is prepared by coating a polyurethane paint layer on a flexible polymeric carrier film. Over the paint layer is coated a clear polyurethane layer. Over the latter is coated a relatively thin layer of a clear polyurethane composition obtained by the reaction of a polyisocyanate with a reactive poly(dialkylsiloxane). Preferably, the latter has at least two active-hydrogen-containing groups, which are hydroxyl, mercapto, primary amino or secondary amino groups. To manufacture the film the compositions are coated on the carrier film by a laminar flow process using an extrusion coating hopper. The resulting film has outstanding gloss and beauty and improved mar resistance. Certain embodiments of the new film can be thermoformed, stretched and bonded adhesively to automobile body parts, boats, or household appliances and other substrates as protective and decorative coverings having a basecoat-clearcoat appearance. Others can be applied to such substrates without substantial stretching as toning and styling stripes.
