Abstract
Abstract The invention relates to the transfer printing hydrophobic fibre materials using paper supports which are printed with azo dyestuffs of the formula ##STR1## wherein X 1 and X 2 represent hydrogen or alkyl or cycloalkyl radicals and n represents 1-3, and wherein the benzene ring A can contain non-ionic substituents and the benzene ring B can contain customary non-polar substituents.
