An embodiment of the present invention relates to a composition comprising a) at least one transparent thermoplastic material; b) at least one inorganic IR absorber comprising at least one boride compound present in an amount of from 0.0015 wt. % to 0.015 wt. %, calculated as solids content of boride in the total polymer composition; and c) at least one inorganic, nano-scale pigment present in an amount of from 0.0008 wt. % to 0.0035 wt. %, based on the total composition; and d) optionally further additives.

Polymer composition having heat-absorbing properties and improved colour properties

The present invention relates to a multilayer system comprising a base layer consisting of a thermoplastic, a primer layer, and a scratch resistant layer consisting of a scratch resistant top coat, the multilayer system being characterized in that the primer layer contains a certain UV absorber and a certain amount of acid, preferably acetic acid, is added to the scratch resistant top coat.

Scratch resistant top coats having good adhesion

The invention relates to triazine-based special organic UV absorbers modified in such a way as to be soluble in polar coating compositions. The invention further relates to coatings, e.g. sol-gel based ones, containing said novel UV absorbers as well as to the use of said coatings for permanently protecting materials, especially plastics, from photochemical degradation.

UV absorbers soluble in polar media

The invention relates to a multilayer product comprising a first layer (A), a second layer (B), a third layer (C), and a fourth layer (D). The first layer (A) is a scratch-resistant protective layer having a minimum extinction of 0.3 at 340 nm, the second layer (B) is an alkyl acrylate layer having a minimum extinction of 2 at 340 nm, and the third layer (C) and the fourth layer (D) contain a UV-stabilized polycarbonate. The invention also relates to a method for manufacturing the multilayer product.

Weather-resistant multilayer systems

The invention relates to multilayer products comprising a layer (A) and a layer (B), wherein layer (A) contains polyalkyl(alkyl)acrylate and has a layer thickness &#x3c;25 [mu]m, and layer (B) contains polycarbonate. The total thickness of layers (A) and (B) is 20 to 500 mm.
