Abstract: A composite film structure which is useful as a non-brittle, impact-resistant, exceptionally durable, window pane in greenhouses and similar structures, or as storm windows, solar collector covers, etc., comprises an oriented polycarbonate support film laminated to a weather-resistant oriented film of polymethylmethacrylate.

Abstract: A paint composition for application at elevated temperatures to form markings on roadways that bear traffic rapidly. The composition includes a paint vehicle and a modifying material dispersed in subdivided form in the paint vehicle. The modifying material is solid and substantially insoluble in the paint vehicle at normal ambient temperatures, and forms an at least substantially dissolved sprayable liquid blend with the paint vehicle at elevated temperatures. As an example, a substantially neutral polyamide reaction product of a polymerized fatty acid and polyamine is dispersed in subdivided form in a paint vehicle that comprises resin-modified drying oils dissolved in a volatile liquid.
