Dry powder for the preparation of aqueous printing inks.

摘要

The dry, powdered ink is designed for the preparation of aqueous printing inks simply by dissolving it in water. It contains at least one water insoluble acidic binder resin and at least one neutralizing agent which, when dissolved, renders the said resin water soluble. Under the conditions of printing, the neutralizing agents is split from the soluble neutral resin which is thus retransformed into its acid, insoluble state. The powder is free from any apparently liquid component.
