ABSTRACT:
The viscosity of aqueous printing inks for gravure printing is adjusted by means of partially organophilic gels which contain plastics mixtures of at least one polymer swelling in water and at least one polymer not swelling in water or to an insignificant extent only, in a solvent mixture of at least two hydrophilic organic hydroxy compounds and one hydrophobic organic hydroxy compound. The printing inks prepared with the aid of the thickener mixtures of the invention contain up to 90% of water, and can be handled as textile printing pastes.
Gravure printing inks on the basis of such plastics gels containing disperse dyestuffs are suitable for the manufacture of transfer printing paper sheets. Since the thickening system adjusting the viscosity contains aqueous alcohols, if any, and no solvents as usual in transfer printing inks, no special measures have to be taken with respect to flammability and explosion risks.
