ABSTRACT:
A polyolefin coated photographic base paper having a silk-like textured surface is prepared by extrusion coating the polyethylene on the photographic paper and, while the polyolefin is still plastic, forming the surface of the polyolefin on an engraved chill roll. Pattern depths of 0.4 to 0.7 mils can be produced on the polyolefin surface by this process using polyolefin films as thin as one mil.
