(57) [Summary] [PROBLEMS] To cure even if a substance inhibiting radical polymerization adheres to the surface of a base material, to achieve antistatic ability, hardness, adhesion, UV Provided is a resin composition for coating capable of providing a protective film having excellent transmittance and excellent water resistance. SOLUTION: The composition and a photomask coated with the composition include a polymerizable acidic phosphate of the formula (I), a silane compound of the formula (II) (such as 3-methacryloxypropyltrimethoxysilane), and a metal. It contains an oxide and a compound having two or more polymerizable unsaturated double bonds (such as pentaerythritol tetraacrylate).
