(57) [Summary] [Problem] To provide a resin composition for forming an ultraviolet shielding layer having both curability and pot life. SOLUTION: A monomer mixture essentially containing a monomer (A1) having a polysiloxane bond and a reactive silyl group, a monomer (B) having an ultraviolet absorbing group, and a monomer (C1) having an alkyl group having 6 or more carbon atoms. (D1) Or a monomer mixture (D2) using a monomer (A2) having only one Si atom in the molecule and having a reactive silyl group directly bonded to a carbon atom instead of (A1) This is a resin composition for forming an ultraviolet shielding layer containing a modified polymer obtained by reacting an organic silane compound with a polymer synthesized from the above (1). |
