Abstract
An alkali-soluble coating formulation is disclosed. Such a coating formulation comprises a volatile, aqueous carrier; an alkali-soluble hydrophilic polymer, in the aqueous carrier; an alkali-soluble multivalent metal ion-containing bond-forming agent, also in the aqueous carrier; and an effective amount of a volatile alkali ingredient, in the aqueous carrier, for dissolving both the hydrophilic polymer as well as the multivalent metal ion-containing bond-forming agent. The relative amounts of hydrophilic polymer and multivalent metal ion-containing bond-forming agent, in the aqueous carrier, are effective for forming an alkali-soluble polymeric coating on a substrate, upon evaporation of the volatile, aqueous carrier therefrom.
