Abstract

Abstract A process for making plastic siding panels, such as outdoor weatherable vinyl panels with an embossed wood grain pattern, comprises extruding a vinyl sheet, and overlaying on the extruded sheet a flexible carrier sheet having coated thereon (a) matte release layer bonded to the carrier sheet, and (b) decorative coating on the matte release layer facing toward the extruded plastic sheet. An embossing roll applies pressure at elevated temperatures to transfer the decorative coating from the matte release layer and bond it to the extruded sheet, while the embossing roll embosses a three-dimensional impression pattern in the laminate transferred to the extruded sheet. The carrier sheet and its matte release layer are then released from the laminate transferred to the vinyl sheet. The matte release layer transfers a low 75 DEG gloss level, preferably in the range of 8 to 12 gloss units, while enabling free release of the carrier from the embossed low gloss surface at elevated temperatures. In one embodiment, a multi-layer wood grain printed acrylic/polyvinylidene fluoride blended decorative coating is simultaneously transferred to a vinyl extrusion and embossed with a three dimensional wood grain texture. A color coat behind wood grain print coats contains pigment at a level that protects the vinyl substrate from UV deterioration. The matte release layer contains a suspended wax which enhances forming the low gloss surface while improving release of the matte release layer from the transferred laminate.
