TEXTURED SCREEN-PRINTED LAMINATES

摘要

A multi-layer laminate having a textured surface comprises a thin, flexible, thermoformable polymeric base layer, and a layer of spaced part segments of an ink material screen printed in a pattern on a surface of the polymeric base material. The ink material comprises a UV curable screen printing ink which contains a resinous binder, a hardener, and a fine particulate filler. The ink is pressed through a screen having an emulsion with a thickness from about 40 to 50 microns. The ink segments are dried on the base layer by UV curing to a height and a hardness sufficient to form a heat stable textured surface adhered to the base layer. In one embodiment, the printed ink layer has a print height from about 25 to about 50 microns and resists deformation from subsequent thermoforming and/or injection molding. The ink segments meet automotive hardness and abrasion specification requirements.
