Appeal No. 1997-0085
Application 08/335,892
The subject matter on appeal relates to a photosensitive
plate which has a thermal distortion which is limited to
specified values. This appealed subject matter is adequately
illustrated by independent claims 1 and 3 which read as
follows:
1. A photosensitive plate suitable for use as a
flexographic printing plate comprising a dimensionally stable,
flexible, polymeric substrate and a photosensitive elastomer
layer, wherein the plate has a thermal distortion in both the
machine and the transverse directions which is less than 0.03%
when the plate is exposed to actinic radiation and, after
exposure, is developed at temperatures between 100 and 180EC.
3. A photosensitive plate suitable for use as a
flexographic printing plate comprising a dimensionally stable,
flexible, polymeric substrate and a photosensitive elastomer
layer, wherein said polymeric substrate experiences less than
0.07% distortion in any planar direction when heated to
temperatures from 110 to 180EC.
