ABSTRACT:
Printing fluid for printing cellulosic materials comprising (a) water; (b) a cationic polyaminoamide/epichlorohydrin resin; (c) a water soluble cationic dye; and (d) 0 up to about 3 wt. %, based on the weight of the printing fluid, of a bleachable pigment. The fluid preferably also contains up to about 50 wt. %, based on the weight of the fluid, of urea to enhance color strength. The printing fluid has excellent bleed resistance to common household products but is nevertheless bleachable so that printed materials such as paper toweling may be repulped and recycled.
