ABSTRACT:
A method for stabilizing a water-soluble resin composition which comprises adding, as a stabilizing agent, a carbonate and/or an organic carboxylate of a basic nitrogenous compound to the water-soluble composition in an amount of from about 0.01 to about 10 parts by weight based on 100 parts by weight of the resin content in the water-soluble composition, the water-soluble composition being prepared by condensation reacting an acid component consisting of 1,2,3,4-butane tetracarboxylic acid alone or a polycarboxylic acid component containing at least about 50 mol% of 1,2,3,4-butane tetracarboxylic acid and a diamine in the presence of a water-soluble solvent or, optionally, in the presence of the water-soluble solvent and water to obtain a condensation product having a residual acid value ratio of about 3 to about 50% of the acid value before condensation followed by formation of a salt of the condensation product with a basic nitrogenous compound.
