Abstract
The invention relates to a process for producing versatile plastic products, preferably single-sidedly self-adhesive products bearing an abrasion-resistant and flexible protective layer which is distinguished by particularly high surface quality especially in terms of its optical properties.
Claims41
Process for producing versatile plastic products, comprising the steps of:
- a) providing a base material coated with a protective layer in the form of a curable liquid varnish formulation,
- b) covering the base material with a cover layer exhibiting a surface roughness at least to the varnish side, with an Rz value of not more than 0.3 μm, and/or a turbidity with a haze value of not more than 5%,
- c) curing the varnish layer through the cover layer, and
- d) detaching the cover layer.
Process according to claim 251 wherein the cover layer has no transparency when curing with electron beams at an irradiated wavelength of 400 nm and in the visible region.
