(57) [Problem] To form a film or coat a substrate, after drying or heat-treating at a relatively low temperature of 70 ° C or less, especially around room temperature to 50 ° C, and even around room temperature, only cold water is required. Provided is a water-resistant composition which is remarkably excellent in water resistance to hot water and hot water, has no problems such as viscosity stability, and has no problem in terms of safety. SOLUTION: An α-olefin unit having 4 or less carbon atoms has one unit. A vinyl alcohol-based polymer having 1 to 20 mol% of α-olefin units having 4 or less carbon atoms and 0.01 to 1 mol% of a silyl group (A) and a chelate type Consisting of a homogeneous mixture of an organotitanium compound (B) having a ligand of (A) The weight ratio (A) / (B) of the component and the component (B) is 9 A water-resistant composition having a ratio of 9.99 / 0.01 to 60/40. |
