STABILIZED BRONZE (COPPER/ZINC) PRINTING INK POWDER

摘要

The present invention provides a stabilized aqueous bronze printing ink formulation comprising (a) a bronze printing ink powder; (b) an aqueous additive formulation. The aqueous additive formulation comprises: i) an emulsifiable wax; ii) a surfactant in the range of from 0.025 to 60 parts by weight of per part of the emulsifiable wax; iii) a base having a pH in the range of 7 to about 12, present in the range of from 0.0005 to 2 parts by weight of the emulsifiable wax; iv) at least one additive in the range of from 0.05 to 160 parts by weight of the emulsifiable wax; and v) at least enough water to render the resulting combination fluid.
