Ink, ink set, and recording device

The invention provides ink, an ink set, and a recording device. The ink comprises a colorant, a polymer particle, water, and a water-soluble organic solvent, wherein the ink has a static surface tension of 30 mN/m or less and, when examined for dynamic surface tension by the maximum bubble pressure...

More Information
Summary:The invention provides ink, an ink set, and a recording device. The ink comprises a colorant, a polymer particle, water, and a water-soluble organic solvent, wherein the ink has a static surface tension of 30 mN/m or less and, when examined for dynamic surface tension by the maximum bubble pressure method, has a width of variations in dynamic surface tension, for a period from 1 msec after to 1 sec after, of 0.2 mN/m to 3.0 mN/m. The image formed by the ink of the invention is improved in the aspects of strike through, image blurring, image peeling, and image graininess.
