Abstract
The present invention relates to a latex paint and more particularly to a paint containing a color change additive. The present invention in one or more embodiments provides for a latex paint including a pH sensitive color change additive, which changes the color of the paint in a certain period of time after application to allow painters to see where they have painted. One or more embodiments of these paint formulations of the present invention are formulated at pH values which allow for greater stability of the color change additive, improved shelf stability of the formulation, longer color change times after application, lower volatile content and odor, and use with existing packaging. The present invention is further directed to a method of applying a paint and painting a substrate white.
