Abstract

A radiation curable resin composition comprises a glycidyloxy groups-containing polybutadiene or hydrogenated polybutadiene, a mono-oxetane compound or monofunctional epoxy compound, and a cationic photopolymerization initiator.

Claims

1. A radiation curable resin composition comprising:

a polyfunctional epoxy polymer (Component A) having a polybutadiene skeleton or a hydrogenated polybutadiene skeleton and two glycidyloxy groups at both terminals in the molecule;

an oxetane compound (Component B) represented by Formula (1) below and/or a compound in which an optionally branched alkyl group having 8 to 30 carbons has one epoxy group (Component C) having 8 to 30 carbons; and

a cationic photopolymerization initiator (Component X),

wherein a number of parts of Component A added is 25 to 45 parts by weight relative to 100 parts by weight of the total resin components

2. The radiation curable resin composition according to claim 1 wherein the composition further comprises an antioxidant.

3. The radiation curable resin composition according to claim 1, wherein the composition further comprises an inorganic ion-exchanger.

4. The radiation curable resin composition according claim 1 wherein the composition further comprises an antioxidant and an inorganic ion-exchanger.

5. A cured material formed by curing the radiation curable resin composition according to claim 1 by irradiation with actinic radiation.

6. A cured material formed by curing the radiation curable resin composition according to claim 2 by irradiation with actinic radiation.

7. A cured material formed by curing the radiation curable resin composition according to claim 3 by irradiation with actinic radiation.

8. A cured material formed by curing the radiation curable resin composition according to claim 4 by irradiation with actinic radiation.
