PROBLEM TO BE SOLVED: To provide an addition type curable silicone coating composition which is provided by uniformly dispersed with zinc oxide ultra fine particles of≤20 nm number average particle diameter and is excellent in transparency, and to provide plastic moldings covered with a coating film. SOLUTION: The addition type curable silicone coating composition contains zinc oxide ultra fine particles surface-treated with a silane compound having a hydrolyzable group and a siloxane group, a hydrosilyl group-containing siloxane compound and an alkenyl group-containing siloxane compound. Optionally, a platinum catalyst and a cure retarder may be contained. And a silicone coating film-covered plastic molding is provided by coating the silicone coating composition and curing. A coating film uniformly dispersed with zinc oxide ultra fine particles at a high content without coagulating each other is provided and is excellent in transparency and UV absorption.
