A composition comprising water and the following components:

Compositions

A compound of Formula (1): ##STR1## wherein: X is E--(L.sup.4 O).sub.m --CO--(T).sub.p ;

Epoxy compounds for use as components of aqueous coating compositions

Process for making a polymer with desired groups Y comprising reacting a precursor polymer having carbon- or nitrogen-bound --NH.sub.2 and/or --NH-- groups with at least one compound having a single enolic carbonyl group and at least one group Y. Also the polymer itself and a composition containing it.

Incorporation of desired groups into polymers, the polymers so produced,

A nonionic dispersing agent suitable for use in the production of aqueous polyurethane dispersions, said agent having the formula: ##STR1## wherein R.sup.1 represents a monovalent hydrocarbon radical containing 1-12 carbon atoms;

Aqueous dispersions

A non-ionic dispersing agent

A water dispersible polyester polymer is described having one or more polyester chains and one or more non-ionic polyoxyalkylene chains in which at least 40% of the repeating oxyalkylene units are oxyethylene units. The polyester polymer has a structure in which one or more of the polyoxyalkylene chains are pendent to at least one of the polyester chains. The poloxyalkylene chains provide the polyester with non-ionic stabilization enabling the polyester to form aqueous dispersions which possess good colloid stability.
