TECHNICAL FIELD

In least one aspect, the present rejection is related multicolor paint compositions that can be applied by a roller.

BACKGROUND

Multicolor paint is a type of paint product that forms a paint coating that possesses multiple colors, typically, multiple color spots upon a light background color. Even though multicolor paint can be applied using various types of spraying, do-it-yourself (DIY) roller application is a big challenge. Currently available products in the market are very poor in DIY roller application properties such as good roll ability, uniform good coverage, spattering, color particle smearing, and the like.

Accordingly, there is a need for improved multicolor paint compositions that can be applied by a roller or other standard application techniques.

SUMMARY

The present invention solves one or more problems of the prior art by providing in at least one embodiment, a multicolor paint composition. The multicolor paint composition includes a continuous phase that includes water and a first rheology modifier that encapsulates discontinuous phases, a first discontinuous phase dispersed in the continuous phase, and a second discontinuous phase immiscibly dispersed in the continuous phase. The continuous phase can include an optional second rheology modifier that is different than the first rheology modifier. The first discontinuous phase includes a first colorant having a first colorant strength, and an emulsion of a non-thixotropic polymer or non-thixotropic copolymer. The second discontinuous phase includes a second colorant having a second colorant strength, an optional third rheology modifier, and an emulsion of a first thixotropic polymer.

In another embodiment, a multicolor paint composition is provided. The multicolor paint composition includes a continuous phase that includes water and a first rheology modifier that stabilizes and/or encapsulates discontinuous phases, a first discontinuous phase dispersed in the continuous phase, and a second discontinuous phase immiscibly dispersed in the continuous phase. The continuous phase can include an optional second rheology modifier that is different than the first rheology modifier. 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, an optional third rheology modifier, and an emulsion of a first thixotropic polymer. The first colorant can be the same or different than the second colorant. Advantageously, the multicolor paint compositions set forth herein allow easy roller application, good coverage with acceptable roller loading frequency, improved resistance to particle smearing, improved particle orientation, and reduced roller spattering. Various embodiments of the multicolor paint composition improve the roller application by using thixotropic resins blended with an optional chelating agent in continuous base to improve finished multicolor paint pattern uniformity. The use of thixotropic resins build up thixotropic behavior and even out the spread of color droplets from roller covers.
