Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
142 words
An ultra-violet ray curing type resin composition, which consists essentially of: (A) at least one kind of cationically polymerizable compound containing, as the principal constituent thereof, an epoxy resin having two or more oxirane rings is one molecule thereof; (B) 0.5 to 20% by weight, with respect to said cationically polymerizable compound, of phenoxy resin having a molecular weight in a range of from 10,000 to 60,000; (C) 0.5 to 20% by weight, with respect to said cationically polymerizable compound, of polyhydric aliphatic alcohol other than (B) containing two or more hydroxyl groups in its molecule; and (D) an effective amount of from 0.5 to 10% by weight, with respect to said cationically polymerizable compound, of a photo-initiator capable of isolating a Lewis acid catalyst which is able to initiate polymerization of said cationically polymerizable compound by irradiation of the ultra-violet rays.
Claim 2
Dependent Claim
142 words
An ultra-violet ray curing type resin composition, which consists essentially of: (A) at least one kind of cationically polymerizable compound containing, as the principal constituent thereof, an epoxy resin having two or more oxirane rings is one molecule thereof; (B) 0.5 to 20% by weight, with respect to said cationically polymerizable compound, of phenoxy resin having a molecular weight in a range of from 10,000 to 60,000; (C) 0.5 to 20% by weight, with respect to said cationically polymerizable compound, of polyhydric aliphatic alcohol other than (B) containing two or more hydroxyl groups in its molecule; and (D) an effective amount of from 0.5 to 10% by weight, with respect to said cationically polymerizable compound, of a photo-initiator capable of isolating a Lewis acid catalyst which is able to initiate polymerization of said cationically polymerizable compound by irradiation of the ultra-violet rays.
Claim 3
Dependent Claim
51 words
An ultra-violet ray curing type resin composition according to claim 1, wherein said photo-initiator is one selected from the group consisting of aromatic halonium salts, and photosensitive aromatic onium salts of the group VIa elements and the group Va elements, and a mixture of two or more kinds of said salts.
