Patent ID: 8221657

Claim:
A transparent or translucent composition comprising a) a compound of formula (I) wherein R is hydrogen, C 1 -C 18 alkyl, C 3 -C 18 alkyl interrupted by one or more O atoms, benzyl or cyclohexyl; R′ is hydrogen or C 1 -C 18 alkyl; or R and R′ together with the nitrogen atom to which they are bonded form a morpholine group; and M is Mn, Zn, V(O), Ti(O), Si, Al, Sn, Cu or Co; which is dispersed in b) a thermoplastic or crosslinkable polymer; wherein the composition is in the form of a sheet or film of a thickness of less than 10 mm and at least 80% translucent in each part of visible range of 400-800 nm; wherein the sheet or film exhibits a full solar radiation of 340-1800 nm transmittance of less than 60%, a full visible light of 400-800 nm transmittance of more than 75% and a haze of less than 1% as measured according to ASTM D-1003, wherein the compound of formula (I) is present in an amount from 0.01 to 10% by weight, based on the weight of the thermoplastic or crosslinkable polymer.
