PHOTOPOLYMER FORMULATION FOR PRODUCING HOLOGRAPHIC MEDIA |
摘要 |
<p>Photopolymer formulation comprises at least one polyol component, a polyisocyanate component, a writing monomer, a photoinitiator and a catalyst, where the photopolymer formulation exhibits an activation temperature >= 8300 K. Independent claims are also included for: (1) producing a holographic medium, comprising (a) producing the photopolymer formulation by mixing all the components, (b) bringing the photopolymer formulation to a desired shape for the holographic medium at a processing temperature, and (c) curing into the desired form with the formation of urethane at a crosslinking temperature above the processing temperature; and (2) a holographic medium, which is obtained by the above mentioned method.</p> |
