Abstract
Novel photosensitive polymer films are provided that include (1) a polymer carrier having .dbd.N--C(.dbd.O)-- groups; (2) an initiation system for photo polymerization; (3) polymerizable compounds; and (4) other chemicals as appropriate. The photosensitive polymer films demonstrate short pump times, short DRAW times, short fix times, and reduced noise levels equal to one-third to one-fifth the noise level of prior photosensitive polymer films.
Claims20
A solution comprising a photosensitive polymer composition for storing holographic images, wherein said photosensitive polymer composition comprises:
- a polymer carrier comprising at least one .dbd.N--C(.dbd.O)-- group;
- a polymerizable compound;
- and
- an initiation system for photo-polymerizing said polymerizable compound, said initiation system comprising:
- a dye;
- and
- a photosensitive initiator comprising an initiator and a photosensitive co-initiator consisting essentially of an amino acid.
