ABSTRACT:
In the manufacture of a decorative sheet material to be bonded to a substrate to provide a surface having a brushed metal appearance, a light-reflective, glossy metal layer is formed on a thermoformable carrier film. A pattern of straight and parallel microscopic cracks is created in the metal layer at a temperature below Tg of the carrier film by bi-directionally bending and drawing the resulting sheet material around a straight cracking member. Thereafter, the sheet material is stretched at a temperature above Tg of the carrier film. This creates an attractive brushed metal appearance of reduced gloss.
