Patent number: 4548613Abstract: C.I. Disperse Yellow 54 and 64 are important yellow dyestuffs of the quinophthalone type used in coloring synthetic fibers, particularly polyamide, polyester, acrylic and acetate fibers at boiling temperature conditions. Yellow azo dyestuffs of the hydroxypyridone type, e.g., C.I. Disperse Yellow 114, 180 227 and 230 have found widespread application in the high-temperature dyeing of such synthetic fibers. It has now been found that improved tinctorial results on these synthetic fiber materials can be obtained by applying a dyeing composition derived from these yellow coloring means and comprising a mixture of 70-90 parts by weight of one or more dyestuffs of the C.I. 54 and 64 type with 5 to 30 parts by weight of an azo dyestuff of the hydroxypyridone type. These improved dyestuff compositions exhibit superior leveling, high tinctorial strength or color build-up, high dyebath exhaustion and deep shade dyeing over the individual components.Type: GrantFiled: May 18, 1984Date of Patent: October 22, 1985Assignee: American Hoechst CorporationInventors: Albert Bode, Thomas V.

Patent number: 4504272Abstract: Color gaps in a product range of reactive dyestuffs are thought of in industry as disadvantageous. The reasons for the existence of gaps can be due to problems of synthesis and reproducibility and also to inadequate wear properties.In accordance with the invention, it has now been found that such missing shades can be dyed by means of mixtures of reactive dyestuffs containing at least two reactive groups and water-soluble, non-reactive dyestuffs containing at least one reactive hydrogen atom. When dyestuff combinations of this type are applied to fibers containing hydroxyl and/or carboxamide groups, the reactive dyestuff fulfills the function of a linking member between the fiber and the non-reactive shading dyestuff, as a result of which a homopolar bond is formed, and this results in very fast dyeings and prints, while at the same time building up the desired shade.Type: GrantFiled: December 21, 1983Date of Patent: March 12, 1985Assignee: Hoechst AktiengesellschaftInventor: Sienling Ong

Patent number: 4502867Abstract: The electrolyte sensitivity of carboxyl-containing synthetic thickeners causes problems on application together with disperse dyestuffs, the commercial finish (dispersants) of which is of anionic nature.These known disadvantages can be eliminated by adding natural thickenings which are based on polysaccharides to the synthetically based products the properties of which are considered unsatisfactory, and setting a certain, acidic pH value in the thickening mixtures. Illustratively, proceeding in this manner it was found on pad-dyeing and printing, for example, polyester fibers with conventionally finished disperse dyestuffs that the use of the auxiliary combinations according to the invention not only stabilized the thickening but also brought about an increase in depth of shade. The systematic pH adjustment of the thickening mixtures results in considerable color yield gains.Type: GrantFiled: December 29, 1983Date of Patent: March 5, 1985Assignee: Hoechst AktiengesellschaftInventor: Friedrich Reinhardt

Patent number: 4474577Abstract: The present disclosure is concerned with new modifications of the dyestuff Color Index Acid Blue 324 which have significant advantages over the known form of this dyestuff. In particular, the preferred modification is much easier to isolate from an aqueous medium by filtration and the isolated product has a higher purity. The filtration proceeds much more rapidly and gives a filter residue of a much higher solids content. Furthermore, this new form of the dyestuff imparts a dramatically lower viscosity to aqueous dispersions or slurries prepared from it than are obtained using the old form of this dyestuff. These modifications are obtained by heating an aqueous dispersion or slurry of the known form of Color Index Acid Blue 324 to temperatures in excess of about 97.degree. C. and for the preferred form in the presence of a substance which reduces the surface tension between the dispersed organic dyestuff phase and the aqueous dispersing medium.Type: GrantFiled: October 26, 1983Date of Patent: October 2, 1984Assignee: Mobay Chemical CorporationInventors: Charles W.
