Abstract:
A process for producing an optical device which comprises the steps of:(a) applying a layer of a photocurable composition onto a substrate; (b) imagewise exposing the photocurable composition to actinic radiation to form exposed and non-exposed areas on the substrate; and (c) removing the imagewise non-exposed areas while leaving the imagewise exposed areas on the substrate; wherein said photocurable composition comprises: a curable component comprising at least one compound having the formula: Râ€”Oâ€”Xâ€”Oâ€”CH&boxH;CH2 â€ƒwherein R is a radical having the formula R1â€”CFHâ€”CF2â€” or R1â€”CF&boxH;CFâ€”, wherein R1 is selected from the group consisting of unsubstituted and substituted aliphatic radicals, unsubstituted and substituted cyclic aliphatic radicals, unsubstituted and substituted aromatic radicals, unsubstituted and substituted araliphatic radicals and unsubstituted and substituted heterocyclic radicals; and X is selected from the group consisting of unsubstituted and substituted aliphatic radicals, unsubstituted and substituted cyclic aliphatic radicals, unsubstituted and substituted aromatic radicals, unsubstituted and substituted araliphatic radicals and unsubstituted and substituted heterocyclic radicals; and a photoinitiator compound so that said composition is photocurable.
