Patent ID: 7947760

Claim:
A composition comprising: a continuous phase comprising water and a carboxylic acid-functional support polymer; a multivalent metal crosslinker selected from the group consisting of Zr, Ti, Hf, Cr, Zn, and Al ions or a combination thereof; a stabilizing agent; and a dispersed phase comprising crosslinked, dispersed polymer particles; wherein: the composition is an emulsion composition; the emulsion composition does not gel after storage for 8 days at 40° C.; the polymer particles comprise polymers polymerized from self-crosslinkable monomers and crosslinked via a crosslinking agent; the emulsion composition is suitable for use as a printing ink; and the emulsion composition provides a printability of less than or equal to 100 prints; wherein: the printability is the number of prints required to regain at least 95% print image quality after a print-stop of at least five minutes on a Moser-type gravure printing press running at 20 m per min in a climate controlled room maintained at 50% relative humidity and 22° C., the Moser-type gravure printing press comprising: a gravure cylinder with 120 lines per cm; an impression roll having a hardness of 75°, a shore printing pressure of 1 bar and a measured contact area of 9 mm; and an in-line Corona treatment of 500 W; and each print is a printed image that is repeated from the same portion of the gravure cylinder.
