Patent ID: 7439279

Claim:
An active energy ray curable coating composition comprising 100 parts by mass of an active energy ray curable polymerizable monomer (A), from 0.01 to 10 parts by mass of a water and oil repellency-imparting agent (B) and from 0.1 to 10 parts by mass of an active energy ray polymerization initiator (C), wherein the polymerizable monomer (A) contains at least 20 mass% of a polyfunctional polymerizable monomer (a-1) having at least two polymerizable functional groups selected from the group consisting of an acryloy group and a methacryloyl group in one molecule, in the total mass of the polerizable monomer (A) contained in the coating composition, and the water and oil repellency-imparting agent (B) contains a water and oil repellency-imparting agent (B-T) having a moiety (b-1) exerting water and oil repellency and which contains at least one portion selected from the group consisting of portions represented by the following formulae (6) to (8): —(CF 2 CF 2 O) p — Formula (6) —(CF 2 CF(CF 3 )O) q — Formula (7) (CF 2 CF 2 CF 2 O) r — Formula (8) wherein each of p, q and r is an integer of from 1 to 100, an active energy ray curable functional group (b-2) and a moiety (b-3) made of at least one portion selected from the group consisting of portions represented by the following formulae (2) to (4): —(CH 2 CH 2 O) x — Formula (2) —(CH 2 CH(CH 3 )O) y — Formula (3) —(C(═O)C u H 2u O) t — Formula (4) wherein, each of x and y is an integer of from 5 to 100, u is an integer of from 3 to 5, and t is an integer of from 1 to 20, and in the water and oil repellency-imparting agent (B-T), the moiety (b-1), the moiety (b-3) and the functional group (b-2) are linearly connected.
