(57) [Abstract] [Problem] A good balance of non-staining adhesion and weather resistance. Moreover, the present invention provides a water-based coating resin composition capable of forming a high-gloss coating film. SOLUTION: 100 parts by weight of a synthetic resin emulsion (A) (parts by weight of solid content of the emulsion) and a compound represented by the formula (I): A silane cup represented by (R 1 O) 3 SiR 2 (wherein R 1 is the same or different and is an organic group having 1 to 20 carbon atoms, and R 2 is an organic group having a cyclic structure and having an epoxy group) 0.1 to 30 parts by weight of the ring agent (B) and, if necessary, the formula (II): (R 3 O) 4-a SiR in 4 a (wherein, R 3 are the same or different organic group having 1 to 20 carbon atoms, R 4 are the same or different organic group having 1 to 20 carbon atoms, a is 0 Or an integer of 1) and / or 1 to 50 parts by weight of a partially hydrolyzed condensate (C) thereof, and a curing catalyst (D). |
