摘要:
Disperse dyes of the general formula (I) where D is a diazo component derived from a substituted or unsubstituted aromatic amine, K is an aromatic radical of the formula and the substituents are each as defined in the first claim. Further described are the preparation and the use of the dyes according to the invention.
摘要:
Compounds of the formula ##STR1## wherein R, R.sub.1 and R.sub.2 are as defined in the specification and R.sub.3 is amino or --N.dbd.N--K, wherein K is a coupling component radical. The compounds wherein R.sub.3 is --N.dbd.N--K are useful as disperse dyes, and those wherein it is amino are useful as intermediates in the synthesis of those wherein it is --N.dbd.N--K.
摘要:
The present invention relates to compounds obtained by condensing a compound of formula I, ##STR1## or a salt thereof, in which R is a primary, secondary or tertiary amino group,with a Vilsmeier reagent,and derivatives of such aldehydes.

摘要:
A compound of the formula I ##STR1## in which D is a diazo component,K is an aromatic group of formula a, b or c, ##STR2## Y is C.sub.2-3 alkylene and the remaining symbols are as defined in the specification. These compounds are useful for dyeing or printing textile substrates based on synthetic or semisynthetic, hydrophobic, high molecular weight organic materials. Preferably, the textile substrate is made from a linear aromatic polyester, cellulose 21/2 acetate or cellulose tri-acetate. The dyeings and prints obtained show good all round fastness properties such as good thermomigration properties, lightfastness, thermofixation, blistering properties as well as good wet fastness properties, especially after thermal fixation.
