Abstract
Compositions comprising PA0 (a) 30-70% by weight of one or more compounds of the formula ##STR1## wherein each R.sub.1 is independently C.sub.2-4 alkyl, and R.sub.3 is methyl or ethyl; and PA0 (b) 30-70% by weight of one or more compounds of the formula ##STR2## wherein R.sub.4 is chloro, bromo or iodo each R.sub.5 is independently C.sub.2-4 alkyl, and R.sub.6 is methyl or ethyl are useful for dyeing substrates comprising a synthetic or semi-synthetic hydrophobic organic material, e.g., polyester, by, for example, the rapid dyeing process.
