Abstract
Disclosed are aqueous coating compositions containing a latex having pendant amine-functional groups, wherein such latex has a Tg greater than about 0 .degree. C. and is capable of film formation at application temperatures, and an amount of base sufficient to raise the pH of the composition to a point where essentially all of the amine functional groups are in a non-ionic state. Also disclosed are methods for producing fast drying coatings on suitable substrates by application of such coatings, where such coatings develop early water-resistance.
