Title:
ACTIVE-ENERGY-RAY-CURABLE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2016/006497
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an active-energy-ray-curable composition capable of improving surface curing properties and imparting flexibility without compromising the good adhesion to a substrate and surface hardness of a polyester (meth)acrylate. The present invention is an active-energy-ray-curable composition including components (A), (B), and (C) in a specific ratio. Component (A): a compound (A1) having two or more (meth)acryloyl groups obtained from a polyol in which 3-18 moles of ethylene oxide are added to dipentaerythritol, and/or a compound (A2) having two or more (meth)acryloyl groups obtained from a polyol in which 2-6 moles of ethylene oxide are added to pentaerythritol. Component (B): a reaction product of a polyhydric alcohol, a divalent carboxylic acid or an acid anhydride thereof, and (meth)acrylic acid. Component (C): a compound having one ethylenically unsaturated group and/or a compound other than component (A) and component (B) and having two or more ethylenically unsaturated groups.
