摘要:
There are described novel dye mixtures of the dyes I and II or Ia and II ##STR1## wherein the symbols have the meanings defined in claim 1. These mixtures can be used in particular for dyeing and printing polyacrylonitrile materials, or mixed fabrics of polyacrylonitrile and wool, the dyeings obtained having a clear, deeply colored blue shade and especially a very good evening shade.
摘要:
The subject of the invention are dyestuffs of the formula ##STR1## wherein R is hydrogen or a hydrocarbon radicalQ is arylX is .dbd.C(W)-- or .dbd.N--,W is a nitrile ester or amide groups andA represents the remaining members of a heterocyclic radical.The dyestuff are preferably suitable for dyeing polyester fibres which are dyed in orange, red, violet or bluish shades with good fastness to light.
摘要:
The invention relates to compounds of the formula ##STR1## WHEREIN Z denotes OH or NR.sup.1 R.sup.2,R.sup.1 denotes hydrogen, alkyl, aralkyl, cycloalkyl or aryl,R.sup.2 denotes hydrogen or alkyl or, conjointly with R.sup.1, forms an alkylene chain.The dyestuffs are outstanding suitable for the dyeing of polyester fibres. The yellow and reddish dyeings are distinguished by good fastness to light.
摘要:
Cationic dyestuffs and processes for their manufacture and their use for dyeing, printing and bulk dyeing of natural and synthetic materials, particularly of polyacrylonitrile and copolymers of acrylonitrile with other vinyl compounds, acid modified aromatic polyesters and acid modified polyamides.
摘要:
Compounds of the formula ##STR1## where A is a heterocyclic group containing a pyridone moiety and R to R.sup.5 are each hydrogen or substituents conventionally encountered in dyes. The compounds are eminently suitable for coloring resins and for dyeing textile materials, particularly polyester textile materials.
摘要:
Printing inks for the production of auxiliary carriers for transfer printing on acid-modified textile fiber materials, characterized in that they contain at leastA. as a dyestuff intermediate, a carbinol base of cationic dyestuffs, which can be sublimed at 160-240.degree. C, of the formula ##EQU1## wherein A, B and D represent an aryl or heteryl radical,B can also denote hydrogen or can, conjointly with A, form the remaining members of a heterocyclic ring system,E represents a direct bond or a >N-alkyl group,L represents a methine group which is optionally substituted by alkyl, nitrile or alkoxycarbonyl or represents a N atom andn denotes the numbers 0 or 1,B. a practically anhydrous neutral organic solvent andC. a neutral resin which is soluble in this solvent.

摘要:
Naphtholactam derivatives bearing one or two arylmercapto groups. The compounds are intermediates for the production of for example disperse dyes and basic dyes.
摘要:
Condensed difluoro or diacetoxy 1,3,2-oxazaborinides are prepared by treating (a) a condensation product of a naphthostyril with an active ketomethylene compound, such as barbituric acid or its N,N-dialkyl derivatives, an indandione, an oxindole or a pyrazolone, (b) a condensation product of an ohydroxybenzaldehyde with an aromatic amine, or (c) an ortho(benz-azol-2yl)-naphthol or phenol, the azole being oxazole, thiazole or imidazole, with either (1) boron trifluoride dissolved in ether, or (2) orthoboric acid, benzeneboronic acid or esters thereof, in acetic acid in the presence of acetic anhydride, at reflux. The difluoro and diacetoxy-1,3,2oxazaborinides are characterized by affinity for polyesters when applied by disperse dyeing methods and fluoresce on the fiber. Similar effects are obtained on nylon and acetate and to some extent on modified polyacrylonitrile.
