Abstract (en)
A process for dyeing condensation prods. (I) comprises treating (I), in the form of fibre, yarn, thread, mesh or web goods or non-wovens, with azo, anthraquinone, coumarin, methine, azamethine, quinophthalone and/or nitro dye(s) in an aq. dyebath at pH 1-12 and 20-250 degrees C. (I) are obtd. by condensing a mixt. of: (A) 90-99.9 mole-% mixt. (a) 30-99 mole-% melamine and (b) 1-70 mole-% substd. melamine(s) of formula (II); and (B) 0.1-10 mole-% phenol (opt. substd. by 1-9C alkyl or OH, 1-4C alkanes substd. by hydroxyphenyl and/or bis(hydroxyphenyl)sulphone; with (C) HCHO (precursor) in a ratio of melamines to HCHO of 1:(1.15-4.5). Y = hydroxy-(2-10C)-alkyl, hydroxy-(2-4C)-alkyl-(oxa-(2-4C)-alkyl)n (n=1-5) or amino(2-12C)-alkyl and some but not all Y may = H.
