<p><P>PROBLEM TO BE SOLVED: To provide a polyfunctional (meth)acrylate resin that has a high crosslinking density after cured by an active energy ray to give a coating film excellent in hardness and scratch resistance, has a small volume shrinkage factor when cured by an active energy ray, and exhibits reduced tackiness before cured by an active energy ray, and a manufacturing method of the same. <P>SOLUTION: The polyfunctional (meth)acrylate resin is obtained by living radical polymerization of a part of (meth)acryloyl groups in a compound (A) bearing at least three (meth)acryloyl groups in the molecule. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
