Bleed-fast cationic dye stuffs

The reaction product of a dialdehyde selected from the group consisting of glyoxal and glutaraldehyde and a cationic, water-soluble dyestuff of the formulae:

• ##STR4## wherein R.sup.0 is hydrogen, lower-alkyl or hydroxy-lower-alkyl;
• R.sup.1 is lower-alkyl, lower-alkenyl or hydroxy-lower-alkyl;
• R.sup.2 is lower-alkyl, lower-alkenyl, hydroxy-lower-alkyl or (lower-alkylene)-NR.sup.0 Y or R.sup.1 and R.sup.2 together with the nitrogen atom, are pyrrolidino, piperidino or 4-lower-alkanoyl piperazino;
• Y is hydrogen or ##STR5## wherein R is hydrogen, lower-alkyl, lower-alkenyl, phenyl or phenyl-lower-alkyl;
• A is a dyestuff residue attached to the quaternary ammonium nitrogen atom through a lower-alkylene bridge;
• k is a small integer whose value is dependent on the nature of A such that it has a range from one to two;
