WATER-BASE COMPOSITION AND CROSSLINKING AGENT FOR WATER-SOLUBLE POLYMERS

摘要

The invention provides a stable crosslinking agent for water−soluble polymers which can impart excellent water resistance and characteristics to water−soluble polymers, and a water−base composition useful as a surface treatment capable of improving characteristics of a substrate surface. The water−base composition consists of a mixed aqueous solution containing a chelating agent whose aqueous solution has a pH of 1 to 7 and a zirconium compound and is useful as a surface treatment, a crosslinking agent for water−soluble polymers, or the like. The chelating agent includes aminocarboxylic acids (such as monoaminomonocarboxylic acids and monoaminodi− carboxylic acids) and derivatives thereof.
