Claim 8:
9. The composition of claim 1, further comprising at least one UV/HEV absorbing compound in the reactive monomer mixture wherein the UV/HEV absorbing compound is selected from 2-(2′-hydroxy-5-methacrylyloxyethylphenyl)-2H-benzotriazole, 2-(2-cyano-2-(9H-thioxanthen-9-ylidene)acetamido)ethyl methacrylate, 2-(2-cyano-2-(9H-xanthen-9-ylidene)acetamido)ethyl methacrylate, 2-(2-cyano-2-(10-methylacridin-9(10H)-ylidene)acetamido)ethyl methacrylate, 3-(3-(tert-butyl)-5-(5-chloro-2H-benzo[d][1,2,3]triazol-2-yl)-4-hydroxyphenyl)propyl methacrylate, a compound of formula II:, wherein:
m and n are independently 0, 1, 2, 3, or 4;
T is a bond, O, or NR;
X is O, S, NR, SO, or SO2;
Y is a linking group;
Pg is a polymerizable group;
R at each occurrence is independently H, C1-C6 alkyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, or Y—Pg;
R1 and R2, when present, are independently at each occurrence C1-C6 alkyl, C1-C6 alkoxy, C1-C6 thioalkyl, C3-C7 cycloalkyl, aryl, halo, hydroxy, amino, NR3R4, or benzyl, wherein R3 and R4 are independently H or C1-C6 alkyl, or two adjacent R1 or R2 groups, together with the carbon atoms to which they are attached, combine to form a cycloalkyl or aryl ring; and
EWG is an electron withdrawing group;
and any combination thereof.
