Abstract
The present invention includes a paint or coating composition comprising an organic pigment or dye complexed to the surface of a layered or fibrous inorganic clay. A wide variety of paint colors can be obtained by varying the pH during the preparation as well as by varying the synthesis conditions and changing particle size of the clay. The paint has unprecedented stability.
