Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
135 words
A PHOTOPOLYMERIZABLE COMPOSITION COMPRISING (1) 10 TO 60 PARTS BY WEIGHT OF A NORMALLY NON-GASEOUS, ETHYLENICLAY UNSATURATED COMPOUND, CONTAINING 1 TO 4 TERMINAL ETHYLENIC GROUPS, HAVING A MOLECULAR WEIGHT LESS THAN 1500 AND A BOILING POINT ABOVE 100* C. AT NORMAL ATMOSPHERIC PRESSURE, AND BEING CAPABLE OF FORMING A HIGH POLYMER BY PHOTOINITIATED ADDITION POLYMERIZATION. (2) 0.001 TO 10 PARTS BY WEIGHT OF AN ADDITION POLYMERIZATION INITIATOR ACTIVATABLE BY ACTINIC LIGHT AND INACTIVE THERMALLY BELOW 85*C. THAT IS SELECTED FROM THE GROUP CONSISTING OF BENZOIN, PIVALOIN; BENZOIN METHYL AND ETHYL ETHER, ALPHA-HYDROCARBON-SUBSTITUTED BENZOINS; BENZAPHENONE; URANYL NITRATE AND ANTHRAQUINONES; (3) 40 TO 90 PARTS BY WEIGHT OF A COMPATIBLE, COHERENT FILM-FORMING MACROMOLECULAR ORGANIC POLYMER HAVING A MOLECULAR WEIGHT GREATER THAN 10,000 AND (4) 0.3 TO 3.0 PARTS BY WEIGHT OF A STANNOUS SALT OF AN ACID.
