<p>PROBLEM TO BE SOLVED: To provide a release coating composition containing an additive useful for fixing uniformly on a substrate, especially on a plastic film. SOLUTION: The curable coating composition comprises (a) a cationically curable functionalized polyorganosiloxane; (b) a photopolymerization initiator; and (c) an anchorage additive having the following formula (1): [wherein, R1 to R3 R7 to R9 are independently alkyl, alkoxy, aryl, aryloxy or alkenyl hydrocarbon or halohydrocarbon groups having 1 to 20 carbon atoms; R4 and R6 are independently alkyl, aryl or alkenyl hydrocarbon or halohydrocarbon group having 1 to 20 carbon atoms; and R5 is an alkyl, aryl or alkenyl hydrocarbon or halohydrocarbon groups having 1 to 20 carbon atoms]. The composition gives a releasably coated, cure film, especially on a plastic substrate, showing a friction rubbed-off amount less than other coated films.</p> |
