COMPOSITION AND METHOD OF USE FOR BLEACHABLE, TRANSFER RESISTANT PIGMENTED INK

摘要

A pigment based ink composition comprised of a bleachable pigment, and a vehicle containing a polyamide amine resin binder. The pigment based ink composition is bleachable, bleed-fast, and is resistant to transfer and upon drying either when exposed to household chemicals or mechanical processes. A method of using the pigment based ink to print on cellulose substrate is provided together with a method of subsequently decolorizing the ink using a bleaching agent.
