  • Patent number: 6355770
    Abstract: Compositions comprising: (a) from about 51% to about 99.9% by weight of a polyamide resin component; and (b) from about 0. 1% to about 49% by weight of a wax component, wherein the polyamide resin component comprises a reaction product obtained by reaction of a dimerized fatty acid reactant, a carboxylic acid reactant and a diamine reactant, are disclosed for use in thermographic printing. The polyamide resin/wax component compositions disclosed herein exhibit decreased bloom and enhanced scratch/scuff resistance.

  • Patent number: 5221699
    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.
