Abstract: A multicolor paint composition includes a continuous phase having a first rheology modifier and an optional second rheology modifier, a first discontinuous phase dispersed in the continuous phase, and a second discontinuous phase immiscibly dispersed in the continuous phase. The first discontinuous phase includes a first colorant having a first colorant strength, and an emulsion of a non-thixotropic polymer. The second discontinuous phase includes a second colorant having a second colorant strength, a third rheology modifier, and an emulsion of a first thixotropic polymer.

Abstract: A multilayer coating that provides a switchable color includes a substrate, an electrically conductive heating paint layer disposed over the substrate, a non-electrically conductive paint layer disposed over the electrically conductive heating paint layer, and a thermochromic paint layer disposed over the non-electrically conductive paint layer. The non-electrically conductive paint layer has a base color at 25° C. The thermochromic paint layer has a first preset color at 25° C. and a second preset color at a switching temperature that is higher than 25° C. Characteristically, the first preset color is matched to the base color. A controllable voltage source is in communication with the electrically conductive heating paint layer to switch between a first preset color and a second preset color.
