    Abstract: Pigment dispersed aqueous ink jet ink compositions suitable for printing on plain paper. The ink comprises water as the principal solvent, a pigment and a pigment dispersant. The pigment dispersant is a derivative of a polyuronic acid in which a hydrophobic polymer is covalently attached to the reducing terminus of the polyuronic acid. The polyuronic acid is composed primarily of 1,4-linked polygalacturonic acid, polyguluronic acid, polyiduronic acid, or mixed polymers thereof.

    Abstract: An ink jet recording method which can simply realize a plurality of resolutions in a single printer without varying the amount of ink per droplet is disclosed. An ink jet recording method comprises the steps of: selecting a recording medium; changing an image resolution depending on the selected recording medium; and ejecting ink droplets onto the recording medium to form ink dots thereon, wherein the amount of ink of the droplet is constant when the resolution is changed, and wherein the image resolution is changed so that ink penetrability or ink repellency of the recording medium makes the diameters of the ink dots on the recording medium fall in the range of from 100 to 160% of diagonal dot pitch of the resolution.

    Abstract: An object is to provide a recorded article or sticker whereby counterfeited articles and genuine articles can be visually distinguished in simple fashion in the market and wherein it is not possible to identify in the market the location and type of the anti-counterfeiting measures that have been taken. Both an overt region 3 (which can be recognized visually in the market) are printing using a color-change ink or liquid-crystal ink, for example, and a covert region 5 formed by for example optical retro-reflective printing (which cannot be recognized without using a special tool) are provided on the surface of the same recording medium. The overt region 3 and the covert region 4 may be arranged at different locations or may overlap, or may be positionally aligned. The overt letter/design pattern and the covert letter/design pattern may be the same or different. An overt recording that is printed using liquid-crystal ink may also function as a covert recording by employing a genuineness inspection method using a circularly polarized plate. A sticker may be provided with one or a plurality of cuts such that the sticker is broken when peeled off, so that it cannot be re-used.
