摘要:
Bright greenish yellow dyes of excellent color value prepared by coupling a lower alkyl anthranilate into 1-phenyl-3-carbalkoxy-5-pyrazolone and having the formula: ##STR1## WHERE R and R.sub.1 are independently lower alkyl; X is hydrogen, halogen, nitro, hydroxy, lower alkyl or lower alkoxy; Y is hydrogen, halogen, lower alkyl or nitro and a and b are integers of 1-2. This class of azo dyes, when appropriately dispersed, produces dyeings on aromatic polyester fabrics with excellent substantivity, outstanding sublimation fastness and good fastness to light. The dyes are applied to polyester, such as polyethyleneterephthalate, by carrier dyeing, pressure dyeing and thermofixation methods.
摘要:
Polyamide fibres are colored with dyestuffs of the formula: ##STR1## wherein A represents the residue of a carbocyclic diazotisable amine, R represents an alkyl group, U represents a linear or branched alkylene group of 1 to 5 carbon atoms, V represents an arylene group, and A, B, R and V are unsubstituted or substituted with non-water-solubilizing substituents, and a process for their preparation which comprises diazotising an amine of the formula:A -- NH.sub.2and coupling the diazo derivative thus obtained with a coupling component of the formula: ##STR2## wherein A, B, R, U and V have the same significance as above. The polyamide fibres exhibit excellent tinctorial yield, very remarkable brilliance, good fastness to washing and to light and good covering of bars.

The azo dye of the formula ##STR1## is a brilliantly red pigment which imparts lightfast and migration resistant color to printing inks, plastics, and the like.
摘要:
A process for the continuous dyeing of synthetic fibrous materials from organic solvents, which comprises impregnating the said fibrous materials with organic dyebaths containing at least one dyestuff of the formula (1) ##SPC1##In which R represents a secondary or tertiary amino group of the formula (2) ##EQU1## in which R.sub.4, R.sub.5 each represents, straight chain or branched alkyl, hydroxyalkyl, lower alkyl --COO-- lower alkylene, and R.sub.4 additionally represents hydrogen lower alkyl --o-- lower alkylene, or R.sub.4 and R.sub.5 represent together with the nitrogen atom the heterocyclic ring ##EQU2## R.sub.1 and R.sub.1 ' each represents hydrogen, chlorine, bromine, lower alkyl, lower alkoxy, nitro or --SO.sub.2 -- lower alkyl, R.sub.2 and R.sub.3 each represents hydrogen, lower alkyl, cyano-lower alkylene, hydroxy- lower alkylene, lower alkylene ##EQU3## lower alkyl, lower alkylene LOWER ALKYL, ##EQU4## lower alkylene-phenyl or phenyl, X represents hydrogen, chlorine, bromine, lower alkyl or lower alkoxy, Y represents hydrogen, chlorine, bromine, lower alkyl, lower alkoxy or acylamino, and subsequently fixing the applied dyestuffs by a heat treatment.
wherein X and Y represent hydrogen or halogen atoms, preferably chlorine atoms, alkyl groups, preferably methyl groups, alkoxy groups, preferably methoxy and ethoxy groups, or nitro groups, R represents benzoyl, hexahydrobenzoyl, alkanoyl, alkylsulfonyl, phenylacetyl, arylsulfonyl, aralkylsulfonyl, alkylcarbamoyl, arylcarbamoyl, alkylthiocarbamoyl or arylthiocarbamoyl groups and R1 represents a hydrogen atom or a phenyl ring which may be substituted by 1 - 3 alkyl, alkoxy, halogen or nitro groups and a process for preparing them which comprises bisdiazotizing diamines of the general formula
AND COUPLING THEM WITH 2 MOLES OF A PYRAZOLONE DERIVATIVE OF THE FORMULA
The new pigment pigments are suitable for the coloring of printing pastes, color lakes and dispersion paints, for the dyeing of plastics and natural resins or artificial resins, such as polymerization or condensation resins. They are furthermore suitable for the pigment printing on a substrate, especially on textile fibers. They may be used for the dyeing of artificial silk made from viscose or cellulose ethers or esters, polyamides, polyurethanes, polyglycol terephthalates or polyacrylonitrile in the spinning mass or for the dyeing of paper. The new pigments have extremely high tinctorial strengths with mostly very pure shades.
