摘要：
An embossed photographic support material is produced by extrusion coating a polyolefin resin over a pattern embossed on a base paper material and pressing the polyolefin resin onto the embossed paper with a cooling roll. The cooling roll has a surface finish to impart the desired amount of gloss to the embossed surface.
