摘要： A protective and decorative polymeric sheet material for bonding to substrates by thermoforming comprises a flexible carrier film, a paint layer on one surface of the carrier film containing a colorant or light reflective flakes or both; and a transparent topcoat overlying the paint layer. At least a portion of the transparent topcoat is a rubbery cushioning layer formed of a non-crosslinked, or lightly crosslinked polymeric composition of low Tg.The sheet material has an unextended state and is heat softenable to a plastic state in which it is extendable to an extended state at least 50% greater in area than the unextended state. The paint and topcoat layers have substantially uniform quality and appearance in both the unextended and extended states. In a preferred embodiment, the thickness of the transparent topcoat is at least 0.1 millimeter. The thick topcoat provides improved retention of gloss and distinctness of image when the sheet material is stretched. As compared with sheet material of which the topcoat layer consists entirely of crosslinked polymer of relatively high Tg, the sheet material of the invention shows a reduced tendency to peel back from the substrate when cut and subjected to high temperature.

摘要： An adhesive-coated thermoplastic film is stretched and bonded to a three-dimensional substrate by vacuum thermoforming at a lower than normal temperature, at which the film has an elastic modulus of at least 10.sup.9 dynes/cm.sup.2, followed by moderate heat treatment of the resulting laminated article. The procedure is especially useful in avoiding air entrapment and peel-back in the thermoforming of a paint-coated film on exterior body panels for automobiles.

摘要： A protective and decorative sheet material for covering substrates comprisesa flexible carrier film,a paint layer adhered to one surface of the carrier film containing light reflective flakes;a transparent polymeric topcoat overlying and adhered to the paint layer having a thickness of at least about 0.1 millimeter.The sheet material has a substantially unstressed relaxed state and a relaxed area and is heat softenable to a substantially plastic state in which it is extendable to an extended state having an extended area up to at least 50% greater than the relaxed area. The paint and topcoat layers have substantially uniform quality and appearance in both the relaxed and extended states. The thick transparent topcoat provides improved retention of gloss and distinctness of image when the sheet material is stretched. A method of preparing the sheet material comprises the step of extruding in laminar flow a layer of a crosslinkable transparent topcoat composition over the paint layer.
