PROBLEM TO BE SOLVED: To provide an ultraviolet-curable resin composition for adhesive, which has excellent adhesive power at a level not causing delamination with time to backing materials made of various materials and excellent step difference followability.SOLUTION: An ultraviolet-curable resin composition for adhesive contains an urethane (meth)acrylate resin (A) obtained by reacting a polyol (a), a polyisocyanate (b) and (meth)acrylate compound having a hydroxyl group (c), (meta)acrylic monomer (B), and a photoinitiator (C). The equivalent of the (meth)acryloyl group in the urethane (meth)acrylate resin (A) is in a range of 8,000-17,000. |
