Abstract
Processes for producing optical devices by 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 the photocurable composition includes:a curable component having at least one compound of the formula:R—O—X—O—CH═CH2 wherein R is R1—CFH—CF2— or R1—CF═CF—, in which R1 is selected from 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 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; anda photoinitiator compou…
