标题:Process for the preparation of dyestuff compositions

摘要:A process for the preparation of new dyestuff compositions which contain one or more basic dyestuffs in the form of dyestuff bases from the series of the triarylmethane, indoldiarylmethane, azine, oxazine, thiazine or xanthene dyestuffs or one or more basic dyestuffs of the series of the azo, anthraquinone, phthalocyanine, styryl, quinophthalone, benzoxanthene, naphthoylene-benzimidazole, naphthalimide or nitro series, carrying a primary, secondary or tertiary amino group or a guanidino or hydrazino group, as well as one or more non-ionic or slightly cationic surface-active agents and, optionally, water and/or an organic solvent miscible with water, which process comprises synthesizing the dyestuff in the surface-active agent optionally containing water and/or an organic solvent miscible with water, and then adding, if necessary, water and/or a solvent miscible with water and a further surface-active agent, this process of the invention having the advantage that an intermediate isolation, drying or grinding of the dyestuffs contained in the dyestuff compositions defined above is not necessary, so that the dyestuffs need not be introduced as substance into the surface-active agent and the solvent in a process wherein compositions of this type are prepared by a usual mixing, kneading or melting process; moreover, higher dyestuff yields are obtained in the dyestuff synthesis, and it allows to prepare dyestuff compositions from dyestuffs which are difficult to be isolated in substance after synthesis and often precipitate as oily or smeary products. The dyestuff compositions obtained according to the process of the invention, which are pastes or liquids, have a high stability upon storage. After being diluted with an aqueous solution of an amount at least equivalent to the dyestuff of an inorganic or organic acid, as well as, optionally, after the addition of dyeing and/or printing auxiliaries, the novel dyestuff compositions are suitable for dyeing or printing textile material containing acid groups.

摘要:Provided is an improved process for the synthesis of 1-cyano-3H-dibenz[f,ij] isoquinoline-2,7-dione compounds, and process exhibiting improvements in quality of products, safety, fewer environmental concerns and economics when compared to presently known processes. The compounds are useful as colorants for polyesters, and selected compounds and when combined with small quantities of certain red colorants are particularly efficacious as blue toners for polyesters.
