Ink jet printing of textiles

An ink jet ink/textile combination comprising:

• a) an ink jet ink containing an aqueous carrier medium, a pigment and a polymer, wherein the polymer has functional moieties selected from the group consisting of acid, base, epoxy and hydroxy moieties;
• and
• b) a textile containing moieties selected from the group consisting of hydroxyl, amine, amido, carboxyl moieties and mixtures thereof, said textile having been treated with a solution consisting of a cross-linking compound selected from the group consisting of:
• i) an organometallic compound represented by the general formula:
• ##STR5## wherein X is a functional group containing oxygen or nitrogen, e.g., ketone, ester, acid salt, etc.;
• Y is alkyl of 1 to 6 carbon atoms or arylalkyl wherein aryl is 6 to 10 carbon atoms and alkyl is 1 to 6 carbon atoms;
• M is Ti, Al, Zn or Zr;
• and
• R is hydrogen, alkyl of 1 to 6 carbon atoms, or hydroxy substituted alkyl of 1 to 6 carbon atoms;
• ii) an organometallic compound represented by the general formula:
• ##STR6## wherein R.sub.1, R.sub.2 or R.sub.3 can be the same or different, and are alkyl of 1 to 4 carbon atoms;
• R.sub.4 is alkyl of 1 to 6 carbon atoms;
• M is Ti, Al, Zn or Zr;
• and
• iii) an isocyanate having the general formula:
• R--(CNO).sub.a
• wherein
• R is a hydrocarbon, aromatic hydrocarbon, aliphatic aromatic hydrocarbon, etc.
• a is 1 or 2;
• wherein upon exposure to an external energy source, the crosslinking compound reacts with the textile and the polymer in the ink.
