PURPOSE:To obtain the subject resin composition freed from sagging or resin during curing and improved in application and drying property, by mixing an epoxy compound with a resol phenol/formaldehyde resin and a specified mixture. CONSTITUTION:100pts.wt. thermosetting resin (A) comprising 5-30pts.wt. epoxy compound of the formula (wherein l, m and n are each 0-2) and 95-70pts.wt. resol/formaldehyde resin is mixed with 100-175pts.wt. mixture (B) of a normally solid acrylic copolymer cationic quat. ammonium salt (a) with a normally solid tert. amine (b) having two 2-hydroxyethyl groups in the molecule in an (a) to (b) ratio of 0.3-0.6. |
