| abstract | Monoazo dyes are made by coupling diazo compounds of aromatic amines free from SO3H, COOH and CN groups with aralkylarylamines free from SO3H and COOH groups of the general formula <FORM:0470398/IV/1> in which R is an alkyl group containing at least one hydroxyl group and X and Y are radicles of the benzene series which may be substituted by halogen, alkyl, hydroxyalkyl, amino or nitro groups. They dye cellulose esters and ethers and colour paraffin wax and stearine and spirit and cellulose ester lacquers. They are also suitable for use as double-tone and intaglio printing inks. In examples, dyes from the following components are described: p-nitroaniline, o-chlor-p-nitroaniline, 2 : 6- or 2 : 5-dichlor-4-nitroaniline; N-hydroxyethyl- N-benzylaniline, N-hydroxyethyl-N-(4-nitrobenzyl)-aniline, N-hydroxyethyl N-benzyl-o-toluidine. Red and brown shades are obtained. R in the above formula may also be hydroxypropyl or dihydroxypropyl. The hydroxyethyl and hydroxypropyl compounds may be made by addition of ethylene or propylene oxide to N-benzylanilines under p pressure and the dihydroxypropyl compounds from chlorpropanediol (1 mol.) and benzylaniline (2 mols.) |
