Abstract
1305754 Fibre-reactive monoazo dyestuffs CIBA-GEIGY AG 14 April 1970 [15 April 1969] 17781/70 Heading C4P The invention comprises fibre - reactive monoazo dyes of formula wherein the benzene nucleas A can be further substituted; Y represents COOH or SO 3 H, X is CH 3 , COOH, COO-alkyl or CONH 2 ; Z is OH or NH 2 ; n is 1 or 2; and Py is a pyrimidyl radical containing at least one replaceable halogen atom. Preferably, Py is the 2,4-difluoro-5- chloro-pyrimidyl-6- radical. The dyes are produced by reacting an aminomonoazo dyestuff of formula with a compound introducing the radical -(CO) n-1 -Py, for example acid halides of pyrimidine carboxylic acids where n = 2 and pyrimidines containing more than one replaceable halogen atom when n = 1. The dyes give yellow shades on textile material of natural and regenerated cellulose fibres, and natural and synthetic polyamide fibres.
