There is provided a resin composition for aqueous paintnwhich has well-balanced non-stain-adhering property and weathernresistance and can provide a coating film having a high gloss. The resinncomposition for aqueous paint comprises 100 parts by weight of ansynthetic resin emulsion (A) (parts by weight of a solid content of thenemulsion), from 0.1 to 30 parts by weight of a silane coupling agent (B)nrepresented by the formula (I): (R 1 O) 3 SiR 2 , wherein R 1 is the same orndifferent and each is an organic group having 1 to 20 carbon atoms, R 2 isnan epoxy-containing organic group having a ring structure and as casendemands, 1 to 50 parts by weight of a silane compound and/or a partlynhydrolyzed condensate thereof (C), in which the silane compound isnrepresented by the formula (II): (R 3 O) 4-a SiR 4 a , wherein R 3 is the same orndifferent and each is an organic group having 1 to 20 carbon atoms, R 4 isnthe same or different and each is an organic group having 1 to 20 carbonnatoms, a is 0 or 1, and further a curing catalyst (D) . |
