Disperse azo dyes

The present invention relates to azo dyes of formula wherein

Disperse azo dyes, a process for the preparation thereof and the use thereof

The present invention relates to disperse azo dyes based on diazo components having at least one fluorine-containing substituent and an 2,6-diaminosubstituted pyridine coupling component, to a process for the preparation of such dyes and to their use in the dyeing or printing of semi-synthetic and, especially, synthetic hydrophobic fiber materials, more especially textile materials.

The present invention relates to azo dyes of formula (1), wherein Rdenotes C-Calkyl which is unsubstituted or substituted by one or more C-Calkoxy groups, hydroxyl groups, amino groups, cyano groups or halogen atoms and which may be interrupted one or more times by the radical &#x2014;O&#x2014;, &#x2014;S&#x2014;, &#x2014;COO&#x2014; or &#x2014;OOC&#x2014;: Ris hydrogen or C-Calkyl; either Ris cyano and Ris halogen or Ris halogen and Ris cyano; and Ar represents a carbocyclic or heterocyclic aromatic radical, to the process for the preparation thereof, to mixtures containing said dyes and to the use thereof in dyeing or printing semi-synthetic and especially synthetic hydrophobic fiber materials, more especially textile materials. 

The present invention relates to disperse azo dyes based on a phthalimido-substituted aniline coupling component and an aromatic-carbocyclic or an aromatic-heterocyclic diazo component, to a process for the preparation of such dyes and to their use in the dyeing or printing of semi-synthetic and, especially, synthetic hydrophobic fiber materials, more especially textile materials.

Azo dyes

The present invention relates to a compound of formula (I) wherein Ris a radical of formula (II) Ris &#x2014;NHor a radical of formula (II), Rand Rare each independently of the other hydrogen, hydroxy, &#x2014;NHor a radical of formula (II), Ris hydrogen, halogen or &#x2014;X&#x2014;(CH)&#x2014;Y, wherein X is a direct bond, &#x2014;O&#x2014; or &#x2014;S&#x2014;, Y is &#x2014;OH or &#x2014;OSOH and n is a number from 0 to 6, with the proviso that at least one of the radicals R, Rand Ris not hydrogen, to a process for the preparation thereof and to the use thereof in a method of producing mass-coloured plastics or polymeric colour particles. 

Anthraquinone dyes

The present invention relates to a compound of formula I wherein Rand Rare each independently of the other &#x2014;NHR, NHSOR, &#x2014;NHCOR, &#x2014;ORor &#x2014;SR, Rand Rare each independently of the other &#x2014;ORor &#x2014;SR, with the proviso that not all of the substituents Rto Rare &#x2014;SR, Ris hydrogen, alkyl, aryl, aralkyl or a group of formula &#x2014;(CHX)&#x2014;H wherein X is &#x2014;O&#x2014;, &#x2014;S&#x2014;, &#x2014;SO&#x2014;, &#x2014;NH&#x2014;, &#x2014;NR&#x2014;, &#x2014;CONH&#x2014; or &#x2014;CONR&#x2014; and Ris alkyl or aryl, n is a number from 2 to 6 and m is a number from 1 to 10, Ris aryl or heteroaryl and Ris alkyl, aryl, heteroaryl or a group of formula &#x2014;(CHX)&#x2014;H wherein X is &#x2014;O&#x2014;, &#x2014;S&#x2014;, &#x2014;SO&#x2014;, &#x2014;NH&#x2014;, &#x2014;NR&#x2014;, CONH&#x2014; or &#x2014;CONR&#x2014; and Ris alkyl or aryl, to a process for the preparation thereof and to the use thereof in a method of producing mass-coloured plastics or polymeric colour particles.

Dyes of the formula ##STR1## in which A.sub.1 and A.sub.2 independently of one another are the radical of a monoazo, polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, thioxanthone, nitroaryl, naphthoquinone, pyrenequinone or perylenetetracarbimide dye,

Dyes, processes for their preparation and their use

Azo dyes of the formula (1) ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 independently of one another are each hydrogen or substituted or unsubstituted C.sub.1 -C.sub.4 alkyl,
