Abstract
An aqueous dispersion coating composition comprising at least one kind of resin, wherein any one of said resin or resins has at least one functional group selected from an active hydrogen-containing group, a substituted acylamide group and a water dispersible or water-soluble group, and wherein the resin composition as a whole contains each of the above described kinds of functional groups.
Claims8
An aqueous coating composition comprising at least one kind of resin, wherein each of said resin(s) has at least one (1) hydroxyl group as an active hydrogen containing group, (2) substituted acylamide group represented by the formula ##STR3## wherein X represents an alkoxy group, an amino group, an amide group, an iminooxy group, a sulfide group, or a mixture thereof, or (3) water-dispersible or water-soluble group selected from the group consisting of a carboxyl anion group, a sulfonic anion group, and a phosphoric anion group,
- wherein said coating composition contains all of the three functional groups in the resin(s) present therein,
- wherein said active hydrogen of said hydroxyl group is present in the resin composition in an equivalence of 1.times.10.sup.-5 or more based on 1 g of all resin components, and
- wherein said water-dispersible or water-soluble group is present in the resin composition in an equivalence of 1.times.10.sup.-4 to 40.times.10.sup.-4 based on 1 g of all resin components.
