Patent ID: 8420281

Claim:
A phototool comprising an optically clear substrate having a designed pattern, and a protective layer on at least a portion of the substrate; wherein the protective layer comprises an at least partially cured hardcoat composition; wherein the hardcoat composition comprises: (a) one or more epoxy silane compounds; (b) one or more epoxy-functionalized perfluoropolyether polyurethane compounds; and (c) photo-acid generator; wherein the epoxy-functionalized perfluoropolyether polyurethane compound has the following general structure: (R f QX 1 C(O)NH) m R i —(NHC(O)X 2 Q(E) o ) n wherein: R f is a monovalent perfluoropolyether moiety; Q is independently a connecting group of valence at least 2, which may contain heteroatoms; X 1 is O, S or NR, wherein R is H or a lower alkyl of 1 to 4 carbon atoms; R i is a residue of a multi-isocyanate; X 2 is O, S, or NR, wherein R is a lower alkyl of 1 to 4 carbon atoms; E is an organic group having at least one oxirane ring; m is at least 1; n is at least 1; o is 1, 2 or 3; and m+n is from 2 to 10.
