Abstract
Ink compositions and methods of use for reliably printing on alkaline and readily oxidizing surfaces comprise one or more water-soluble polymeric dyes, one or more solvents for adjusting viscosity, surface tension, and/or heat tolerance, and water, the dyes being 'loaded' in the ink sufficiently to meet the relevant color and optical density requirements for the ink while such ink composition still also meets the duty cycle requirements of the application.
