Patent ID: 7252785

Claim:
A composition comprising i) at least one radiation-absorbing tert-alkylphenoxy-substituted polycyclic compound A of formula I where P is a conjugated polycyclic radical that is stable to bases and nucleophiles, optionally bears aryl substituents and contains no group from the group consisting of —CO—NH—CO—, —COOH and —CO—O—CO—; R is C 1 -C 8 -alkyl, wherein the carbon chain of said C 1 -C 8 -alkyl may be interrupted by one or more groups selected from the group consisting of —O—, —S—, —NR 1− , —CO— and —SO 2 — and which may be monosubstituted or polysubstituted by identical or different radicals selected from the group consisting of C 1 -C 6 -alkoxy and a 5- to 7-membered heterocyclic radical that is attached via a nitrogen atom and may contain further heteroatoms and/or may be aromatic; or R is C 5 -C 8 -cycloalkyl, wherein the carbon framework of said C 5 -C 8 -cycloalkyl may be interrupted by one or more groups selected from the group consisting of —O—, —S—, —NR 1− , —CO— and —SO 2 — and which may be monosubstituted or polysubstituted by C 1 -C 6 -alkyl; R 1 is hydrogen or C 1 -C 6 -alkyl; Hal is chlorine or bromine or mixtures thereof; m is from 0 to 15; and n is from 1 to 16, wherein the sum m+n is ≦16 and ii) at least one curable IR-reflecting component B which comprises a) at least one achiral nematic polymerizable monomer and at least one chiral polymerizable monomer; b) at least one cholesteric polymerizable monomer; c) at least one cholesteric crosslinkable polymer; or d) at least one cholesteric polymer in a polymerizable diluent.
