Abstract
A method of preparing a resin composition for hard coat, comprises: a first step of obtaining a polyfunctional (meth)acrylate monomer modifying agent by addition reaction between a modifying agent having a thiol group and a three- or more functional (meth)acrylate monomer to form a covalent bond between the thiol group and acryloyl group and/or methacryloyl group, and a second step of modifying metal oxide microparticles with the polyfunctional (meth)acrylate monomer modifying agent that is obtained from the first step.
