[57] [Summary] [Problem] It has unprecedented quick-drying property, maintains strong initial tack for a long time, and enables full-scale bonding with water-based adhesive workability such as strong contact adhesiveness. A water-based silanolized urethane-based resin composition is provided. SOLUTION: A polyisocyanate compound (a), a MW500 to 3,000 polyol compound (b) having no anionic group, a polyol compound (c) having no anionic group less than MW500, a polyol compound having an anionic group (b) d) and an alkoxysilyl compound (e) having a secondary amino group, by converting the NCO group of a / all OH groups of b to d = 1.02 to 1.2, The compound (A) obtained by reacting with OH group of c / OH group of b = 0.1 to 4.0, water and a basic substance are blended. |
