[PROBLEMS] To provide a method for producing a hard coat resin composition capable of satisfying various performance conditions such as mechanical properties such as friction resistance and surface hardness, weather resistance and storage stability, and a hard coat resin composition obtained by using the method. [Method] In the method for producing a resin composition for hard coat, a thiol group, an acryloyl group and / or a methacryloyl group using a thiol group-modifying agent and a trifunctional or higher functional (meth) acrylate monomer using an addition reaction It has a 1st step which covalently bonds and obtains a polyfunctional (meth) acrylate monomer modification modifier, and the 2nd step which modifies the polyfunctional (meth) acrylate monomer modification modifier obtained by the 1st step to metal oxide fine particles. |
