Abstract: An adhesive includes: a urethane prepolymer (A) obtained by reacting a polyol (a) with a polyisocyanate (b) under such conditions that the molar ratio of NCO/OH is 0.5-0.9 and having a molecular-weight dispersion degree [(weight-average molecular weight (Mw))/(number-average molecular weight (Mn)); hereinafter referred to also as Mw/Mn] of 4-12; a polyfunctional polyol (B), and an isocyanate curing agent (C).

Abstract: This adhesive includes a copolymer that includes monomer units represented by (a-1), (a-2), (a-3), and (a-4) described below, and the following content is contained among all of the monomers which constitute the copolymer: (a-1) 5 to 45 wt % of an alkyl(meth)acrylate; (a-2) 0.01 to 10 wt % of a (meth)acrylate having a hydroxyl group or an allyl ether having a hydroxyl group; (a-3) 50 to 78 wt % of an alkoxyalkyl (meth)acrylate; (a-4) 1 to 25 wt % of an alkoxypolyalkylene glycol mono(meth)acrylate or an alkoxypolyalkylene glycol allyl ether.
