Abstract
The photopolymer comprising the matrix polymer, polyfunctionalmonomer, radical initiator, and sensitizing dye are sensitive to visible light to give the holographic recording material for an argon ion laser exposure. The radical exposure involves 3, 3', 4, 4'- tetrakis(t-butyloxycarbonyl)benzophenone(BTTB, I) and iron-arene complex (II), and the sensitizing dye is ketocoumarin(III). The photopolymer gave the sensitivity from 0.1-4 mJ/cm2, depending on the holographic recording angle, for 488 nm argon ion laser light. Large-size rainbow holograms, 50 cm X 40 cm, were successfully recorded with this photopolymer with 10 sec exposure.
