Abstract
Disperse dyestuffs which are sufficiently capable of subliming for serving in the transfer print process but which yield printing inks of a too high viscosity can be finished to fit the requirements for printing inks for transfer printing by treating said dyestuffs in a liquid medium at a temperature between 50.degree. and 180.degree. C. Thus printing inks of sufficiently low and constant viscosity can be obtained.
