Document Type and Number:
Japanese Patent JPS5155321
Kind Code:
A
Abstract:
Disclosed are azo dyes of the formula wherein R1 is an aliphatic or aryl group, R2 is cyano, alkoxycarbonyl or substituted alkoxycarbonyl, R3 is an aliphatic or aryl group, and K 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.
