The present invention relates to a process for producing transparent polymeric films or plastics moldings of particularly high chemical resistance, having more particularly a very good resistance towards oil-in-water and water-in-oil emulsions, and of high optical quality.

Chemical-resistant films in high optical quality

The present invention describes a process for the surface finishing of materials via application of specific polymethacrylate layers. The polymethacrylate layers are composed of blends of at least two (co)polymers of polymethacrylates, and specific 'reactive monomers' are present here in a polymerized mixture which forms the polymethacrylate layer. At the application temperature established, these form a chemical and, where appropriate, also a physical bond to the substrate, and therefore have adhesion-promoting action.

Method for surface hardening substances by application of particularly transparent polymethacrylate layers

The invention relates to a novel UV-protective and weather-resistant package for surface protecting films for polyvinyl chloride window profiles made of poly(meth)acrylate. Matrix plastics having great molecular weights are used in order to obtain great weather resistance of the surface protecting films.

PMMA film featuring particularly great weather resistance and great UV protection

The present invention relates to a foil encompassing at least one PMMA layer coloured with a yellow anthraquinone dye, where the chromaticity coordinates (x;y) in the CIE 1931 Standard Colorimetric System of the PMMA layer are within the range of 0.4&#x2266;x&#x2266;0.54 and 0.44&#x2266;y&#x2266;0.54, where the concentration of the yellow dye of the PMMA layer is at least 3% by weight, based on the total weight of the PMMA layer.
