The present invention provides a resin composition for forming protective film. The protective film has high surface smoothness on the substrate and various excellent properties, such as transparent, heat-resistant and so on based on the non-smooth the surface, even though the coating method is a slit coating method. The solution of the present invention is to provide a resin composition for forming protective film comprising: (A) a polymer having a repeating unit from epoxy group-comprising polymerized unsaturated compound (B) at least one of compound selected from the group consisting polyvalence carboxylic anhydride polyvalence carboxylic acid, (C) a specific polymer having a polysiloxane chain, (D) a compound having more than two cations polymeric group, and (E) a alkoxysilane compound having a epoxy group. |
