Abstract
A process for the pretreatment of textile material consisting entirely or partially of cellulose fibers and which is to be printed according to the thermotransfer process, which comprises impregnating the textile material with a solution or dispersion containing PA1 (a) a compound of the formula I EQU NH.sub.2 --CO--Y--R (I) PA1 wherein R stands for a group of the formulae R.sub.a, R.sub.b or R.sub.c ##STR1## in said formulae R.sub.1 is hydrogen or C.sub.1-4 alkyl, R.sub.2 is C.sub.1-4 alkyl, R.sub.3 is hydrogen or methyl, n is an integer of from 1 to 6, m is an integer of from 1 to 10, X is CH.sub.2 or O and Y, in case that R stands for R.sub.a or R.sub.b is an oxygen atom and in case that R stands for R.sub.c is an oxygen atom or an imino group (NH), PA1 (b) a glyoxal or melamine formaldehyde resin and PA1 (c) an acid catalyst for the condensation of these resins, and subsequently drying the textile material and subjecting it to the action of heat.
