    • 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.
    • 具有纹理表面的多层层压板包括薄的,柔性的,可热成形的聚合物基底层,以及在聚合物基材的表面上以图案印刷的油墨材料丝网的间隔部分段的层。 油墨材料包括含有树脂粘合剂,硬化剂和细颗粒填料的UV可固化丝网印刷油墨。 将油墨通过具有约40至50微米厚度的乳液的筛网压制。 油墨段通过紫外线固化在基底层上干燥至足以形成粘附于基底层的热稳定纹理表面的高度和硬度。 在一个实施方案中,印刷油墨层具有约25至约50微米的印刷高度,并抵抗随后的热成型和/或注射成型的变形。 油墨段符合汽车硬度和磨损规格要求。
