Patent ID: 7074351

Claim:
A composition comprising (a) at least one transparent thermoplastic polymer; (b) oxide particles selected from one or more of (i) indium oxide in which from 2 to 30% of indium atoms are replaced by tin atoms; (ii) indium oxide in which from 10 to 70% of oxygen atoms are replaced by fluorine atoms; (iii) tin oxide in which from 2 to 60% of tin atoms are replaced by antimony atoms; (iv) tin oxide in which from 10 to 70% of oxygen atoms are replaced by fluorine atoms; (v) zinc oxide in which from 1 to 30% of zinc atoms are replaced by aluminum atoms; (vi) zinc oxide in which from 2 to 30 percent of zinc atoms are replaced by indium atoms; (vii) zinc oxide in which from 2 to 30 percent of zinc atoms are replaced by gallium atoms; (viii) perovskites; and (ix) compounds of formula A x BO 3âˆ’y wherein: 0.01<x<3; 0.001<y<1.5; A=Ca, Sr, Ba, Al, In, Sn, Pb, Cu, Ag, Cd, Li, Na, K, Rb, Cs, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, H or NH 4 ; B=W, Mo or Re; wherein an average particle size of the oxide particles is less than 200 nm and a surface of the oxide particles is modified with a surface modifier selected from a polyvinylacetal and a compound of formula (I) SiR 1 R 2 R 3 R 4 (I) wherein R 1 is selected from alkyl groups having from 6 to 30 C atoms; R 2 is selected from alkyl groups having from 1 to 30 C atoms, alkoxy groups having from 1 to 30 C atoms, Cl, Br and I; R 3 is selected from alkyl groups having from 1 to 30 C atoms, alkoxy groups having from 1 to 30 C atoms, Cl, Br and I; R 4 is selected from alkoxy groups having from 1 to 30 C atoms, Cl, Br and I; (c) one or more organic NIR absorbers; and (d) at least one UV absorber which comprises a hydroxy benzotriazole compound.
