Abstract: PROCESS FOR THE DYEING AND PRINTING OF SYNTHETIC POLYAMIDES It had been found that dyestuffs of the formula (1), in which p stands for an integer of from 1 to 6, and W represents, as a water-solubilizing group, the sulfo group, the sulfato group (-OSO3H), the thiosulfato group (-S-SO3H), the carboxyl group, the phosphato group (-OPO3H2), the phosphonic acid group (-PO(OH)2) or the phosphonic acid-semi-ester group of the formula -PO(OR)OH, wherein R represents an alkyl radical of from 1 to 5 carbon atoms, preferably the methyl or ethyl radical, are very suitable in dyeing and printing processes of synthetic polyamide fiber materials and yield brilliant and very fast dyeings and prints on these materials, especially even dyeings of textured polyamide f which have differences in stretching.

Abstract: Dyestuffs consisting of the mixture of isomers of the formulae and wherein R1 is hydrogen, alkyl with 1 to 20 carbon atoms, alkoxyalkyl or alkoxycarbonyl alkyl each with 1 to 4 carbon atoms per alkyl moiety, benzyl, alkoxycarbonyl with 1 to 20 carbon atoms per alkyl moiety or phenyl, R2 is alkoxycarbonyl with 1 to 20 carbon atoms per alkyl moiety, cyano, alkanoyl or alkoxyalkoxycarbonyl each with 1 to 4 carbon atoms per alkyl moiety, carbonamido, phenylcarbonamido, mono- or dialkylcarbonamido with 1 to 8 carbon atoms per alkyl moiety or cyclohexylcarbonamido, R3 and R4 are identical and are hydrogen or alkoxy with 1 to 4 carbon atoms or R3 is alkoxy with 1 to 4 carbon atoms and R4 is hydrogen and R is phenylthio which may be substituted by one or two chlorine or bromine atoms or alkyl, alkoxy, carbalkoxy or alkylsulfonyl groups each having 1 to 4 carbon atoms per alkyl moiety or a cyano, trifluoromethyl or nitro group; naphthylthio, pyridinethio, benzimidazolyl-2-thio, benzoxazolyl-2-thio, benzthiazolyl-2-thio or an amino group of the formula wherein R5 and R6 represent hydrogen, alkyl or hydroxyalkyl each with 1 to 4 carbon atoms or phenyl, or together are piperidine, morpholine or piperazine. The new dyestuffs are very suitable for the dyeing of synthetic materials such as polyethylene-glycol torephthalate, acetyl cellulose or polyamides. They yield brilliant greenish yellow to orange red shades which have a good fastness to light and to thermofixation. They are also very suitable for the dyeing of fibre-forming polymers such as for example polyethylene-glycol terephthalate in the mass. Furthermore, a big part of the dyestuffs can be used for dyeing synthetic fibre materials sucll as polyester fibres from organic solvents, for example perchloroethylene.

Abstract: of the disclosure: New benzoxanthene- and benzothioxanthene-dicarboxylic acid imide compounds containing in the aliphatic or aromatic imide radical one or two water-soluble groups but no sulfo group in the benzene nuclei of the xanthene skeleton, had been found which are suitable as dyestuffs for dyeing or printing natural or synthetic polyamide and have very good dyeing and fastness properties, especially a good fastness to alkali and a good dyeing behavior to texturized polyamide fibres containing differently drawn fibre moieties which were dyed in even shades.

Abstract: 1439994 Preparation of 4-chloronaphthalic acid, its anhydride, salts and derivatives HOECHST AG 30 Aug 1973 [30 Aug 1972] 40793/73 Heading C2C The invention comprises a process for the preparation of 4-chloronaphthalic acid, its anhydride, salts and derivatives which comprises chlorinating naphthalic acid or an anhydride, salt or derivative thereof in a solution containing alkali metal, hydroxide or carbonate and having a pH of 6.8-9.0 and then, if necessary, converting the obtained 4-chloroproduct to the required acid, salt, anhydride or derivative by a method known per se. The chlorination may be carried out using Cl 2 or hypochlorite and the exemplified product is 4-chloronaphthalic anhydride.

Abstract: Dyestuffs consisting of the mixture of isomers of the formula I wherein X is oxygen or sulfur, R1 is hydrogen, alkyl having 1 to 20 carbon atoms, methoxycarbonylmethyl, ethoxycarbonylmethyl, lower alkoxycarbonyl or phenyl, R2 is alkoxycarbonyl having 1 to 20 carbon atoms, lower acyl or benzoyl, cyano, carbonamido or phenylcarbonamido, R3 and R4 represent simultaneously hydrogen or lower alkoxy or R3 is lower alkoxy and R4 is hydrogen, R5 and R6 are hydrogen or halogen atoms, lower alkyl, alkoxy or alkoxycarbonyl. These dyestuffs yield brilliant yellow to red dyeings in synthetic polymers especially in polyethylene terephthalate with an intense yellow green to orange fluorescence. Due to their high fluorescence they can also be used for preparing daylight fluorescent pigments.

Abstract: A process for the preparation of 4-bromo-naphthalic acid anhydride by bromination of an alkali metal salt of naphthalic acid in an aqueous medium at a pH of 6.8 to 9 by dropwise adding 0.55 to 0.65 mol of bromine per mol of naphthalic acid and oxidizing the bromine at the same pH-value with chlorine. By this process 4-bromo-naphthalic acid anhydride can be obtained in a quantitative yield whereby the formation of 4-chloro-naphthalic acid is avoided.

Abstract: 1345176 Luminescent materials FARBWERKE HOECHST AG 19 April 1971 [14 April 1970] 26913/71 Heading C4S A daylight fluorescent pigment comprises a condesnate resin and a fluorescent dye having a formula in which X is oxygen or the group >N-R, R is hydrogen or an optionally substituted alkyl, cycloalkyl or aryl radical, a heterocyclic radical, a hydroxy group or the group -NH-Z in which Z is hydrogen, an optionally substituted alkyl or aryl radical, a heterocyclic radical or an acyl, alkyl-sulphonyl or aryl-sulphonyl radical; R 1 and R 2 , which may be the same or different, represent hydrogen, a halogen atom, e.g. Br or Cl or an alkyl alkoxy, aryl, carbalkoxy or cyano group; R 3 is hydrogen or an optionally substituted alkoxy group; and R 4 is hydrogen or R 3 and R 4 both represent optionally substituted alkoxy groups. Y is oxygen or sulphur and n is zero, 1, 2, or 3. Resins include cross linked polyesters, amideformaldehydes and amino-triazine formaldehydes. Preferred dyes are benzoxanthenes and benzothioxanthenes prepared by heating diazonium salts in the presence of Cu or Cu salts. Pigment is prepared by adding benzoxanthene- 3,4-dicarboxylic acid anhydride-di-sulphonic acid and resin, then paraformaldehyde to p-toluene sulphonamide at 130‹ C. The temperature is increased to 160-170‹ C. and on cooling a brittle material forms which is ground to a particle size of 0À1-30 Á. The pigment is used for paint, laquer, printing ink or to colour plastics material.
