Method of manufacturing holographic photopolymers on polymer films |
摘要 |
<p>Producing photopolymer films comprises coating a carrier film with a photopolymer formulation comprising e.g. a polyisocyanate component comprising at least one isocyanate-terminated polyurethane prepolymer; isocyanate-reactive polyether polyol; urethane acrylate and/or urethane methacrylate with at least one aromatic structural unit and a refractive index of greater than 1.50-405 nm; radical stabilizers; photoinitiators based on combinations of borate salts and one or more dyes with absorption bands; and optionally catalysts, according to the roll-to-roll principle. Producing photopolymer films comprises coating a carrier film with a photopolymer formulation comprising a polyisocyanate component, comprising at least one isocyanate-terminated polyurethane prepolymer whose isocyanate groups are bound to primary aliphatic group and which is based on hydroxy-functional compounds with a hydroxyl functionality of 1.6-2.05; isocyanate-reactive polyether polyol; urethane acrylate and/or urethane methacrylate with at least one aromatic structural unit and a refractive index of greater than 1.50-405 nm, which is free itself of isocyanate-groups and hydroxy groups; radical stabilizers; photoinitiators based on combinations of borate salts and one or more dyes with absorption bands, which cover at least in part to the spectral range of 400-800 nm; optionally catalysts; and optionally auxiliary materials and additives, according to the roll-to-roll principle.</p> |
