Abstract:
A solid substrate having a surface suitable for printing on, prepared by the process comprising:providing a solid substrate having an exposed surface; and directly applying a single image-enhancing composition to the exposed surface, wherein the image-enhancing composition comprises: (a) an image-enhancing agent selected from the group consisting of (i) an acidic salt of a guanidine polymer comprised of monomer units having the structural formula (IV) â€ƒwherein n is an integer in the range of 1 to 10 inclusive, R3 is hydrogen or lower alkyl, and R4 is hydrogen, alkyl, alkoxy, or hydroxyl-substituted alkoxy; (ii) a mixture of an azetidinium polymer and an acidic salt of a guanidine polymer comprised of monomer units having the structural formula (IV); and (iii) a copolymer comprised of an azetidinium monomer unit and a guanidine monomer unit; wherein the image-enhancing agent represents approximately 5 wt. % to 95 wt. % of the image-enhancing composition, based upon total solids weight of the composition after drying; and (b) approximately 1 wt. % to 40 wt. % of a film-forming binder composition based upon total solids weight of the composition after drying, in (c) a liquid vehicle.
