COMPOSITION AND MOLDED ARTICLE OF AMORPHOUS POLYOLEFIN

PROBLEM TO BE SOLVED: To provide a composition suitable for a coating forming a cured film which is excellent in adhesion to a plastic substrate, especially to an amorphous polyolefin substrate, having the hardness imparting scratch resistance, wear resistance, etc., and excellent in surface protecting performance. SOLUTION: The composition comprises 5-50 pts.mass of an urethane (meth)acrylate (component A), prepared by reacting a polydienepolyol (component a1) having at least two hydroxy groups in a molecule, an organic polyisocyanate (component a2), a compound (component a3) represented by formula (1), and a compound (component a4) having a hydroxy group and at least one of polymerizable unsaturated double bond in the molecule, and 5-50 pts.mass of inorganic particles (component B) treated with an organic compound, and 20-90 pts.mass of a compound (component C) having at least two polymerizable unsaturated double bonds in the molecule excluding the component A, and a photopolymerization initiator (component D), wherein the sum of the components A, B and C is 100 pts.mass.
