Abstract
A process for producing a laminate that exhibits an orange peel effect having a wavescan DOI value of 5 to 80 as determined by BYK Gardner apparatus is disclosed. The process comprise a) obtaining a carrier layer a first surface of which exhibits specifically measured roughness value and b) applying a sealing layer to the first surface, the protective layer positioned on the side remote from the carrier film. The inventive laminate is particularly suitable in automotive applications.

A process for producing a laminate a surface of which having a wavescan DOI value of 5 to 60 as determined by BYK Gardner apparatus comprising
- a) obtaining a carrier layer having a temperature of 50° to 150° C. a first surface of which exhibits roughness value, Rz, of 1 μm to 6 μm determined according to DIN EN ISO 4288,
- b) applying a sealing layer having a temperature of 80° to 180° C. to said first surface, the protective layer positioned on the side remote from the to carrier film,
- c) carrying the product of b) through two counter rotating rolls whereby at least one of the rolls having a temperature of 80° to 180° C. and thereby pressing the product and, achieving the laminate,
- said carrier layer containing at least one film of at least one member selected from the group consisting of polycarbonate, acrylonitrile/butadiene/styrene, polymethyl methacrylate, styrene/acrylonitrile, polybutylene terephthalate, polyethylene terephthalate, polyamide, polyester, acrylic/styrene/acrylonitrile, said sealing layer including a protective and optionally at least one colored layer.
