Abstract
The heat-transfer coloring process using sublimable disperse dyestuffs can be applied on cellulosic materials if these are treated with an aqueous preparation containing a thickening agent and an addition compound of a lower alkylene oxide onto a compound having active hydrogen atoms. If the thickener is a synthetic polymer containing carboxy group the alkylene oxide addition compound can be omitted.
