<p>PROBLEM TO BE SOLVED: To obtain the subject composition excellent in preservation stability, and showing less process soiling in its use and a good working efficiency by containing a compound containing glycidyl group and a compound containing an acid anhydride. SOLUTION: This resin composition is obtained by containing (A) a compound having preferably 5,000-1,000,000 weight-average molecular weight (based on a polystyrene, using a gel permeation chromatography method) and 150-2,000 g/eq epoxy equivalent (JIS K-7236), (e.g.; a high molecular weight epoxy resin) with (B) a compound having preferably 500-500,000 weight-average molecular weight (based on a polystyrene) and containing an acid anhydride in a ratio of (the epoxy equivalent of the component A)/(the acid anhydride equivalent of the component B)=0.2-5. As the component B, a (co)polymer having a compound such as maleic anhydride, itaconic acid anhydride, himic acid anhydride, succinic acid anhydride, etc., as a constituting unit is cited.</p> |
