Abstract
The present invention relates to a process for printing hydrophobic fibre materials with disperse dyes, which comprises a procedure in which the fibre materials A) are dyed over the entire area or printed over the entire area with a disperse dye and PA1 B) are printed in areas with a printing paste comprising PA2 at least one disperse dye, PA2 at least one cationic dyeing assistant and PA2 at least one nonionic detergent it being possible for steps A) and B) to be carried out in any sequence and for step B) to be repeated several times with different dyes, the fibre material treated in this way is dried and the dye is then fixed on the fibre material by a heat treatment. Multicolored prints with sharp contours and very good fastnesses to hot light are obtained by the process according to the invention.
