Abstract: A pigment composition for use as a substrate to produce ink, paints, and pigment compounds, the composition being made from an aqueous slurry containing about 17 to 40% calcium carbonate, based on the weight of said aqueous slurry, and an inorganic pigment from group comprising titanium dioxide, in which the amount of calcium carbonate is higher than that found in standard pigment compositions and the amount of amount of pigment is lower than that found in standard pigment compositions, yet there is not an appreciable degradation of the color, coating, and other qualities of the pigment composition.

Abstract: A light-modifying composition comprising a color pigment component and a pigment spacer component characterized by being a transducing material having the ability to absorb light and reflect at least part of the light absorbed, thereby modifying the light in the coating resulting from the application of the composition. Such pigment spacing component includes any material having the ability to partially absorb light. Preferred are neutral grey pigments in the form of grey powders having a minimal color producing effect. The pigments can be in the form of ground grey powders such as powders taken from granite, feldspar, quartz or limestone or in the form of spherical metallic particles such as metallic zinc.
