  • Patent number: 5677262
    Abstract: A process for obtaining a low gloss, dye-receiving element for thermal dye transfer comprising extrusion laminating a support with 1) a polyolefin resin and 2) a composite film comprising a microvoided thermoplastic core layer and a substantially void-free thermoplastic surface layer, the extrusion laminating process being performed with an embossed chill roll having a surface roughness average (Ra) of at least 1.5 .mu.m and a pressure roll, and then coating the composite film with a polymeric dye image-receiving layer, thereby producing the low gloss, dye-receiving element.
