(57) [Summary] [Structure] [A] As a functional group, a compound represented by the general formula: [In the formula, R represents a hydrogen atom or a methyl group, and R 1 is A hydrogen atom or a hydroxyl group, an alkoxyl group, an ester group, or a halogen element having 1 to 1 carbon atoms which may be substituted. The hydrocarbon group of 8 is shown below. Indicates. Here, Z represents a nitrogen atom or a phosphorus atom, and Y Represents a sulfur atom. R 2 , R 3 and R 4 are the same or different and each represents an organic group having 1 to 14 carbon atoms. In addition, R 2 and R 3 or R 2 , R 3 and R 4 are Together, they may form a heterocyclic group with the nitrogen atom, phosphorus atom or sulfur atom to which they are bonded. ] A resin component having an aprotic onium salt-containing group, a hydroxyl group, an epoxy group, and a hydrolyzable group directly bonded to a silicon atom or a hydroxysilyl group, and an element selected from [B] aluminum, zirconium and titanium An aqueous curable resin composition comprising the metal chelate compound as described above. [Effect] The composition of the present invention is an aqueous composition having excellent storage stability and good curability, and the resulting cured product has excellent water resistance. |
