Abstract
The invention comprises water-insoluble monoazo dyes free from sulphonic and carboxylic acid groups and having the general formula <FORM:1119326/C4-C5/1> wherein R1 is H, halogen, alkyl, alkoxy, CN, CF3, or carboalkoxy; R2 and R3 are H, halogen, alkyl, alkoxy or carboalkoxy; X and Y are H, halogen, alkyl or alkoxy; R4 is an optionally substituted alkyl group or an R5 radical which is <FORM:1119326/C4-C5/2> wherein R6-R9 are H or C1-C2 alkyl groups, and R is H or COR10 wherein R10 is an optionally substituted C1-C5 alkyl group. The optionally substituted alkyl groups may contain halogen atoms or CN or carboalkoxy groups. They are prepared by the usual diazotization and coupling methods, preferably at neutral pH values. They give yellow-brown, orange, red, scarlet and violet shades on hydrophobic fibre material, e.g. aromatic polyesters, cellulose esters, synthetic polyamides and polyacrylonitrile.ALSO:The compound <FORM:1119326/C2/1> is prepared by reacting b -chloro-b -1-acetoxy-diethyl ether with 1-N-ethyl amino-3- methyl benzene at 120 DEG to 140 DEG C. in presence of sodium acetate. The product may be isolated by means of water or methanol/water mixture.
