    • There is described a water-based paint composition comprising least one pigment; at least one alkali soluble polymer in an amount effective to increase the open time of the composition; at least one substituted amine in an amount effective to adjust the pH to about 7 to about 11: a binding effective amount of at least one water dispersible acrylic polymer; and an effective amount of at least one alkali soluble or alkali swellable thickener. A method of extending the open time of a water-based acrylic paint composition and a method of controlling the open time of a water-based acrylic paint composition are also described.
