9 Claims

1. A textured press plate for use in manufacture of decorative laminate, the textured press plate being manufactured by the method comprising:

applying a UV curable acrylate mixture directly to a surface of a press plate substrate, the UV curable acrylate mixture comprising an aliphatic urethane triacrylate oligomer, an aliphatic urethane acrylate oligomer, and a reactive diluent;

irradiating the UV curable acrylate mixture that has been applied to the press plate substrate with an excimer emitter such that the UV curable acrylate mixture is only crosslinked on a surface thereof to create a UV-irradiated layer having a surface exhibiting micro-folding; and

fully curing the UV-irradiated layer to form a textured coating layer on the surface of the press plate.
