Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
114 words
AN IMAGE-FORMING ELEMENT WHICH COMPRISES, IN ORDER, (1) A SHEET SUPPORT, (2) A SOLID PHOTOPOLYMERIZABLE STRATUM COMPRISING (A) AN ADDITION POLYMERIZABLE, NON-GASEOUS ETHYLENICALLY UNSATURATED COMPOUND CONTAINING AT LEAST ONE TERMINAL ETHYLENIC GROUP (CH2=C<), HAVING A BOILING POINT ABOVE 100*C. AT NORMAL ATMOSPHERIC PRESSURE AND BEING CAPABLE OF FORMING A HIGH POLYMER BY FREE-RADICAL INITIATED CHAIN PROPAGATING ADDITION POLYMERIZATION, AND (B) A PREFORMED, COMPATIBLE COHERENT FILM-FORMING, MACROMOLECULAR ORGANIC POLYMER HAVING A MOLECULAR WEIGHT GREATER THAN 10,000 AND BEING SOLID AT 50*C., COMPONENTS (A) AND (B) BEING PRESENT IN AMOUNTS OF 10 TO 60 AND 40 TO 90 PARTS BY WEIGHT, RESPECTIVELY, (3) A HYDROPHOBIC COPOLYMER LAYER, AND (4) A RADIATION-SENSITIVE, WATER-PERMEABLE COLLOIDSILVER HALIDE EMULSION LAYER.

Claim 3
Dependent Claim
63 words
A PROCESS WHICH COMPRISES EXPOSING, IMAGEWISE, TO LIGHT AN ELEMENT AS DEFINED IN CLAIM 1, DEVELOPING AND FIXING THE EXPOSED SILVER SALT, EXPOSING THE RESULTING ELEMENT TO ACTINIC RADIATION UNTIL THE EXPOSED AREAS OF THE PHOTOPOLYMERIZIBLE STRATUM ARE POLYMERIZED WITHOUT POYLMERIZATION IN UNEXPOSED AREAS AND REMOVING THE HYDROPHOBIC COPOLYMER LAYER, EMUSION LAYER AND UNEXPOSED PORTIONS OF SAID STRATUM TO FORM A PRINTING RELIEF.
