URETHANE RESIN CONTAINING (METH)ACRYLOYL GROUP, ACTIVE ENERGY RAY CURABLE ADHESIVE CONTAINING THE URETHANE RESIN, AND BACK SURFACE PROTECTIVE SHEET FOR SOLAR CELL |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide an active energy ray curable composition that produces a back surface protective sheet for a solar cell having excellent adhesion force between sheet-like members and wet heat resistance, not causing poor appearance by occurrence of foams in an adhesive layer and delamination in a high yield at a low cost and in excellent productivity (aging is not needed). <P>SOLUTION: The urethane resin (C) containing a (meth)acryloyl group is obtained by reacting a diol component (A) that essentially comprises a diol component having a carbonate structure but not contains a (meth)acryloyl group with a polyisocyanate component (B) that has a (meth)acryloyl group and two or more isocyanate groups. The active energy ray curable adhesive comprises the urethane resin (C). <P>COPYRIGHT: (C)2012,JPO&INPIT |
