摘要:
A process for producing monoazo or disazo pigments, which process comprises:(a) adding to a solution of a diazonium and/or tetrazonium salt of an aromatic or heterocyclic amine a solution or suspension containing 0.1-50% by weight of the theoretically required total weight of one or more coupling components, and(b) using the product from step (a) as an additive in the production of a monoazo pigment, a disazo pigment or a mixture of monoazo and disazo pigments.Compared with products produced by conventional methods, the pigments produced in the manner described above have a greater coloring strength, improved transparency, improved flow properties, and a higher degree of dispersibility.
摘要:
The invention is directed to transfer sheets for heat transfer printing polyester textiles in yellow hues, to inks that are useful in making such transfer sheets, to an improved process for heat transfer printing polyester textiles and to the printed or dyed fabrics thereby produced; the yellow hue being imparted by the use of at least one compound having the structure: ##STR1## wherein R.sub.1 is lower alkyl.
摘要:
Disclosed are azo dyes of the formula ##STR1## wherein R.sub.1 is an aliphatic or aryl group,R.sub.2 is cyano, alkoxycarbonyl or substituted alkoxycarbonyl,R.sub.3 is an aliphatic or aryl group, andK is a coupling component radical,The synthesis thereof and the use thereof for the dyeing and printing of textile and non-textile substrates. The disclosed disperse dyes are useful for dyeing and printing synthetic and semi-synthetic, hydrophobic, high molecular weight materials such as linear aromatic polyesters, polyamides, cellulose 21/2 acetate and cellulose triacetate. The obtained dyeings have satisfactory fastness properties, particularly fastness to light, thermofixation, sublimation and pleating.
