An acrylic multilayer foil includes a layer A in which silica particles are uniformly distributed in an acrylic polymer matrix and a coating layer D. Due to adhesive promoting properties of the layer A containing silica particles, the coating layer D can be advantageously applied onto the layer A. The foil has a high weathering resistance and excellent mechanical properties. Therefore, the foil is highly suitable for surface-protection of materials such as polyvinyl chloride (PVC) and for use in high-pressure laminates (HPLs).

Acrylic multilayer foil with improved mechanical properties and a high weathering resistance

The present invention relates to novel films for application on materials as protective film in respect of weathering effects. In particular, the present invention relates to a novel film composite which has at least three layers and which features particularly good adhesion on the substrate and particularly good optical properties. The outermost layer here is a layer comprising a fluoropolymer, the middle layer is a PMMA layer comprising at least one UV absorber and/or UV stabilizer, and the innermost layer is a PMMA layer comprising at least one adhesion promoter which improves adhesion on the substrate.

Three-layer UV protective film for decorative laminated sheets (HPL)

The present invention relates to novel matt PMMA foils for application on materials as foil providing protection from weathering effects and as decorative foil. In particular, the present invention relates to a novel, at least two-layer PMMA foil which features particularly good adhesion on the substrate. The outer layer here exhibits the mattness, and the inner layer here comprises a low-molecular-weight component which improves adhesion on the substrate.

Co-extruded impact-modified PMMA film

The present invention relates to a method for producing light guide bodies and to their use in lighting units, for example for liquid crystal displays or for monitors. In particular, the present invention relates to a method for producing light guide bodies which have a thickness of at most 1 mm and contain at least 80 wt % of polymethyl methacrylate and no light-scattering constituents.

Method for producing light guide bodies and use thereof in lighting unit

The invention describes a transparent plastics composite composed of PMMA and TPU with excellent mechanical properties.

Transparent plastic composite

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.
