- Water-soluble fiber reactive dyes
-
Water-soluble fiber-reactive azo, metal complex azo, anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, stilbene, triphenylemthane, xanthene, thioxanthone, nitroaryl, naphthoquinone, pyrenequinone or perylenetetracarbimide dyes which contain once or twice the group of the general formula STR1 in which: Rx and Rz are, independently of one another, hydrogen or lower alkyl, which can be substituted by halogen, hydroxyl, cyano, lower alkoxy, lower alkoxycarbonyl, carboxyl, sulfamoyl, sulfo or sulfato; W is fluorine, chlorine, bromine, sulfo, phenylsulfonyl or alkylsulfonyl of 1 to 4 carbon atoms; Y is vinyl, β-substituted, β-thiosulfatoethyl, β-phosphatoethyl, β-alkanoyloxyethyl of 2 to 5 carbon atoms in the alkanoyl radical, β-benozoyloxyethyl, β-(sulfobenzoyloxy)ethyl, β-(p-toluenesulfonyloxy)ethyl or β-halogenoethyl. The fiber-reactive dyes are highly suitable for the dyeing of carboxamido-containing and/or hydroxyl-containing materials, such as, for example, synthetic polyamide fiber materials, wool and in particular cellulose fiber materials with a high degree of fixation in hues which have a high color strength and good fastness properties.

- Esters of 3-tert-butyl- and 3-tert-butyl-5-alkyl-4-hydroxyphenyl (alkane) carboxylic acids with oxyethylates of polythiols
-
Esters of 3-tert-butyl- and 3-tert-butyl-5-alkyl-4-hydroxyphenyl (alkane) carboxylic acids with oxyethylates of polythiols are useful as stabilizers for polymers, especially for polyethylene and polypropylene.
