Abstract
Abstract Disclosed are new zirconic acid esters which contain glycol ether moieties as the ester grouping, and which are chelated with one and up to a maximum of two moles of acetylacetone. The new compounds can also contain up to a maximum of two moles of ester groupings of low alkanols. The new partially chelated zirconic acid esters are characterized by good solubility in water, in which they do not decompose at room temperature. Accordingly, they can also be used in aqueous systems as crosslinking agents or reaction accelerators.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
64 words
