Abstract
Materials made of or containing cellulose esters and ethers are coloured by applying thereto and retaining in the materials a compound containing two aryl radicles or aromatic residues united directly by a single linkage which compound contains a single amino group and a single nitro group in ortho relationship to each other. The amino group and also the nuclei may be further substituted. The dyestuffs may be applied in the form of dispersions (cf. Specifications 219,349, 224,925, 242,393, 242,711, 269,960, 273,819, 273,820, 322,737, and 323,788, [all in Class 15 (ii), Dyeing, Processes &c. for]). Preparations containing the dyestuffs and dispersing agents are also referred to. In examples, cellulose acetate alone or mixed with cotton or viscose (which may be dyed with a direct cotton dye) is coloured with (1) 3-nitro-4-aminodiphenyl, (2) 3-nitro-4-amino-4<1>-chlorodiphenyl, (3) 3-nitro-4-amino-2 : 2<1>-ditolyl. Yellow shades fast to light and volatilization are obtained. Specification 283,253, [Class 15 (ii), Dyeing, Processes &c. for], also is referred to.
