The present invention provides an adhesive composition for optical disks comprising n (A) a radiation-curable oligomer, for instance a urethane (meth)acrylate obtainable by reacting a polyol compound, a polyisocyanate compound, and a (meth)acrylate compound containing a hydroxyl group, and n (B) dialkylaminobenzoate. n The invention also provides a composition comprising radiation-curable oligomer (A) with n (C) a hydroxyalkyl (meth)acrylate, and n (D) at least one compound selected from the group consisting of 2,2-dimethoxy-1,2-diphenylethan-1-one, 2-hydroxy-2-methyl-1-phenylpropan-1-one, and 1-hydroxycyclohexyl phenyl ketone. n The compositions of the present invention may be used as adhesives for optical disks. |
