PROBLEM TO BE SOLVED: To provide a compsn. for color filter protective films which is good in flatness and tight adhesive property, facilitates the liquid management of the compsn. for the protective films and is easy to handle. SOLUTION: Water of 0.3 to 5 pts.wt. in outer percentage is added to 100 pts.wt. compsn. which contains (A) a photopolymerizable (meth)acrylate monomer, oligomer, (B) a non-acrylic epoxy group-contg. resin, (C) a silane coupling agent and (D) water, is formulated to (A)/(B)=5O/50 to 95/5 by weight and from which a solvent and water is removed. Further preferably, an epoxy hardener is added at 3 to 90 to 100 non-acrylic epoxy group-contg. resin by weight.
