Abstract
The present invention relates to a curable resin composition, etc., having an excellent transparency, applicability, and workability. Specifically, the present invention relates to a resin composition, etc., including: (A) a polymer having two or more (meth)acryloyl groups in one molecule thereof; (B) a silica powder surface-treated with an alkyl silane; and (C) boric acid or a borate ester.
