Claim 18:
19. The radiation-curable resin composition according to claim 18, wherein
the urethane oligomer with an ethylenic unsaturated group contains an alkoxysilyl group-containing urethane oligomer having one (meth)acryloyl group at one end and one alkoxysilyl group at the other end, and a free-radically polymerizable alkoxysilane, and
the free-radically polymerizable non-urethane monomer contains a free-radically polymerizable alkoxysilane, and
the ratio of the total number of moles of the alkoxysilyl group-containing urethane oligomer and the free-radically polymerizable alkoxysilane with respect to the number of moles of the non-free-radically polymerizable alkoxysilane is from 0.05/1 to 4/1.
