Patent number: 4607096Abstract: Azo pigments are obtained by diazotizing a diazotizable aromatic amine without solubilizing groups in anhydrous dipolar aprotic water-miscible solvents with the stoichiometric amount or a small excess of nitrosylsulfuric acid or nitrosyl chloride, coupling the diazonium compound so obtained with a coupling component and isolating the pigment obtained in usual manner. This process is carried out in homogeneous solution and yields azo pigments the advantageous properties of which cannot be achieved by other methods, for example, the excellent purity, grain softness, narrow range of particle size distribution, excellent dispersibility in plastic materials and color lacquers, high gloss and excellent opacity in color lacquers.Type: GrantFiled: November 4, 1982Date of Patent: August 19, 1986Assignee: Hoechst AktiengesellschaftInventors: Josef Landler, Klaus Hunger, Erhard Worfel

Patent number: 4552951Abstract: This invention relates to azo dyes which may be unsubstituted or substituted with a variety of groups known to the dye art, and containing a diazonium moieties from an aniline type compound and certain coupler moieties from aniline, tetrahydroquinoline, or benzomorpholine compounds, wherein the diazonium moiety has one or two cinnamoyl substituents, and wherein one or more water-solubilizing groups such as a sulfonic acid group or its metal or amine salt may be present as a substituent in the dye molecule for acid dyeing. These dyes are particularly useful in dyeing one or more of polyamide cellulose acetate polyester, wool and other fibers.Type: GrantFiled: January 23, 1984Date of Patent: November 12, 1985Assignee: Eastman Kodak CompanyInventor: Robert N.
