Kind Code:
A1
Abstract:
A radical-curable hot-melt urethane resin composition which comprises a (meth)acryloyl-containing hot-melt urethane (X) and a radical polymerization initiator (Y), wherein the urethane (X) is an isocyanate-terminated hot-melt urethane prepolymer (C) which is obtained by reacting a polyol (A) that comprises an aliphatic polycarbonate polyol (a1), an alicyclic polycarbonate polyol (a2), or an aliphatic polyether polyol (a3) with an alicyclic polyisocyanate (B) and in which more than 50 to 100 mol% of the total isocyanate groups are modified by the introduction of (meth)acryloyl groups with an active-hydrogen-containing (meth)acrylate compound (D). The radical polymerization initiator (Y) is contained in an amount of 0.5 to 5.0 parts by mass relative to 100 parts by mass of the urethane (X).
