Abstract:
1. A multi-layer product comprising a first layer (S1) and a second layer (S2), the first layer being prepared from A) 20 to 95 wt. % of one or more aliphatic polymer precursors selected from the group consisting of B) 5 to 80 wt. % of one or more fine-particle inorganic compounds, C) 0.8 to 5 wt. % of at least one organic UV absorber which is a compound according to the following formula (IV) wherein X═OCH(R R R D) 0 to 10 wt. % of one or more radical scavengers of the hindered amine light stabilizer (HALS) class E) 0 to 5 wt. % of one or more flow control agents F) one or more solvents in an amount such that a solids content of 20 to 50 wt. % for the mixture of components A, B and F results of, and G) 1 to 5 wt. %, based on the amount of components A and B of one or more compounds selected from the group consisting of bis(2,4,6-trimethylbenzoyl)-phenyl phosphine oxide, 2,4,6-trimethylbenzoylethoxyphenyl phosphine oxide, 2-methyl-1-[4-(methylthio)phenyl]-2-morpholino-1-propanone, and a mixture of bis(2,6-dimethoxy-benzoyl)(2,4,4-dimethylpentyl)phosphine oxide and (1-hydroxy-cyclohexyl)phenylmethanone wherein the amounts of components C, D and E are based on the weight of solids in the mixture of components A, B and F, the amount of components A and B total 100 wt, % and wherein the second layer comprises a thermoplastic polymer.
