Abstract
Abstract This invention provides an absorbent composition comprising a reactant product of (1) amines or amides; (2) carbon disulfide, or carbonyl sulfide; (3) polyvalent metal ions; and, (4) a water-dispersable reactive polymeric material. A water-soluble silicate may be present as an optional material during the reaction. The reaction is carried out in an alkaline water solution or dispersion, and the above noted absorbent composition then precipitates. The resulting absorbent composition may be used as an ion exchange medium; to form lakes by absorption of dyes soluble or dispersable in water or water-immiscible solvents; to absorb from water solutions or dispersions of toxic or otherwise objectionable materials such as chromates, lead or mercury salts, etc.; to absorb dye intermediates, which when absorbed may be further reacted to form dyes which remain on the composition of this invention; to coat paper and facilitating ink absorption on paper; to manufacture pigments which blend readily in oleophylic vehicles, as well as in hydrophylic vehicles.
