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.
