Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
108 words
In a photosensitive element wound in a roll comprising a flexible support bearing at least one layer of a photopolymer composition and a removable cover sheet, said support having greater adhesion than the cover sheet to the photosensitive element and furthermore the support is strippable from the photopolymer composition or transmits actinic radiation, whereby the improvement comprises the cover sheet having a roughened finish on its surface which faces toward the photosensitive composition and whereby the photosensitive composition follows contours of the cover sheet whereby the surface roughness of the photosensitive composition is in an average range of from 2 microns to 11 microns, peak to valley distance.
Claim 2
Dependent Claim
108 words
In a photosensitive element wound in a roll comprising a flexible support bearing at least one layer of a photopolymer composition and a removable cover sheet, said support having greater adhesion than the cover sheet to the photosensitive element and furthermore the support is strippable from the photopolymer composition or transmits actinic radiation, whereby the improvement comprises the cover sheet having a roughened finish on its surface which faces toward the photosensitive composition and whereby the photosensitive composition follows contours of the cover sheet whereby the surface roughness of the photosensitive composition is in an average range of from 2 microns to 11 microns, peak to valley distance.
Claim 3
Dependent Claim
36 words
