Patent ID: 7179308

Claim:
A coating composition comprising (i) one or more polymerizable vinyl compounds, (ii) one or more colorant compounds according to Formula I: wherein L represents a covalent carbon—carbon bond or a linking group selected from the group consisting of —O—, —S—, —SO 2 —, —CON(R 2 )—, —N(COR 3 )—, —N(R 2 )CO—, and —N(SO 2 R 3 )—; R is a divalent organic radical selected from the group consisting of C 1 –C 6 -alkylene; C 1 –C 6 -alkylene-Y—CH 2 CH 2 —; and —(CH 2 CH 2 )— m —Y—CH 2 CH 2 —; R 1 is hydrogen or represents one or two groups selected from the group consisting of C 1 –C 6 -alkyl, C 1 –C 6 -alkoxy and halogen; R 2 is hydrogen, C 1 –C 6 -alkyl, C 3 –C 8 -cycloalkyl or aryl; R 3 is C 1 –C 6 -alkyl, C 3 –C 8 -cycloalkyl or aryl; X is —O— or —N(R 2 )—; Y is —O— —S—, —SO 2 —, —N(SO 2 R 3 )—, or —N(COR 3 )—; n is 1 or 2; m is 2 or 3; and Q is an ethylenically-unsaturated photopolymerizable or free radical polymerizable group, and (iii) at least one photoinitiator.
