PURPOSE:To provide the titled composition having excellent adhesivity, cohesivity and weather-resistance, by adding a specific amount of an ultraviolet absorber having unsaturated double bond to a liquid oligomer having unsaturated double bond in the molecule. CONSTITUTION:The objective composition is composed of (A) 100pts.(wt.) of a liquid oligomer having unsaturated double bond in the molecule (preferably imparted with acrylic double bond having high reactivity), (B) 0.1-30pts. of an ultraviolet absorber imparted with an unsaturated double bond, preferably containing phenyl salicylate, hydroxybenzophenone, or hydroxyphenyl benzotriazole in the molecular skeleton, (C) a chain transfer agent (e.g. butyl mercaptan) and (D) a reactive monomer having polar group (preferably imparted with phosphoric acid radical).
