PURPOSE:To obtain a curable pressure-sensitive adhesive composition which is suitable as a self-adhesive by blending a specific curable polyester oligomer with a tacky rubbery polymer. CONSTITUTION:A curable pressure-sensitive adhesive composition comprising 100 pts.wt. tacky rubbery polymer and 5-200 pts.wt. curable polyester oligomer obtained by react a hydroxylic and/or amino compound, a cyclic acid anhydride and, as epoxides, both of an epoxide having a radical-polymer zable unsaturated group and an epoxide having no radical-polymerizable unsaturated group. The composition has a tackiness upon joining, can bond tentatively to objects, and cures by heating or exposure to light or only by laminating to exhibit a strong adhesive force. Hence, it is a curable pressure-sensitive adhesive composition suitable as so-called self-adhesive. |
