  • Patent number: 7442725
    Abstract: An improved color changing correction fluid is provided which includes either a volatile base or a volatile acid in combination with a color changing pH indicator, all in a water based fluid or system. As the fluid dries, the volatile base or acid evaporates along with the water and the pH color changing indicator changes from a colored state to a clear state. For white paper, a white pigment is utilized and therefore the fluid changes from a colored state to a white finished state as the solvent water and acid or base evaporates. Different color pigments can be utilized to match the color of the particular paper or substrate.

  • Patent number: 7427641
    Abstract: There is provided an ink composition which can yield records possessing excellent rubbing/abrasion resistance and scratch resistance. Specifically, records possessing excellent rubbing/abrasion resistance and scratch resistance can be produced by using an ink composition comprising: an alkali-soluble copolymer; water; a colorant; and at least one member selected from the group consisting of wax, a viscosity modifier, and a wetting agent. The alkali-soluble copolymer is a copolymer, with an acid value of not more than 40, which is produced by polymerizing an ethylenically unsaturated carboxylic acid monomer and other monomer copolymerizable with the ethylenically unsaturated carboxylic acid monomer in the presence of an alcoholic hydroxyl-containing water-soluble polymer compound or a copolymerizable surfactant and has been adjusted to a pH value, at which the copolymer is soluble in water, by the addition of an inorganic base.
