Abstract:
The present invention relates to an ultraviolet curable resin composition for optical substrate bonding, which is characterized by comprising a sulfur-containing compound (A) having at least two intramolecular groups represented by formula (1), a photopolymerizable compound (B), and a photopolymerization initiator (C), and an optical member (such as a touch panel or display device with a touch panel) that uses the same. The resin composition is characterized in that the cure shrinkage rate is low, curability and flexibility are excellent, and there is little discoloration of the cured film, even under a high-temperature environment; the composition is extremely useful as an optically transparent adhesive agent; and the composition is appropriate for adhering the protective substrate of a touch panel, adhering a touch panel and a display body, and the like. -CH2SR1 (1) (In the formula, R1 is an alkyl group having 1 to 20 carbon atoms.)
