    Abstract: A wipe-erasable ink composition for a writing board has good erasability and long-period stability. This ink composition comprises a coloured polymer formed by dyeing an organic solvent-soluble resin having a sulphonic acid group or a salt thereof with a basic dye, a volatile organic solvent and, as additives, (A) a nonionic surface active agent having an HLB value of 8 to 14 and/or a cationic organic compound, and (B) a slightly volatile or nonvolatile organic compound.

    Abstract: COLORING MATERIAL AND PROCESS FOR PREPARATION THEREOF A coloring material comprising a solution of an alcohol-soluble resin having a sulfonic acid group or a salt thereof, which is dyed with a basic dye, in a solvent comprising an alcohol as a main component. The coloring material is prepared either by (a) polymerizing an ethylenically unsaturated sulfonic acid or a salt thereof in water and adding a basic dye to the obtained aqueous liquid of the formed polymer or (b) carrying out said polymerization in the presence of a basic dye, and dissolving (i) the obtained aqueous liquid of the formed colored polymer or (ii) a colored polymer obtained by removing water from the obtained aqueous liquid of the formed colored polymer in a solvent comprising an alcohol as a main component; or, (a') carrying out said polymerization in a solvent comprising an alcohol as a main component and then adding a basic dye to the obtained polymer solution, or (b') carrying out said polymerization in the presence of a basic dye.

    Abstract: AQUEOUS COLORED POLYMER, PROCESS FOR PREPARING SAME AND INK COMPRISING SAME An aqueous colored polymer is provided, which comprises (a) a homopolymer of an ethylenically unsaturated sulfonic acid or its salt or (b) a copolymer of an ethylenically unsaturated sulfonic acid or its salt with other ethylenically unsaturated monomer, said homopolymer or copolymer being dyed with a basic dye and having a lowest film-forming temperature of not higher than 35.degree.C. The aqueous colored polymer is prepared by polymerizing an ethylenically unsaturated sulfonic acid or its salt, or its mixture with other ethylenically unsaturated monomer by an aqueous solution or emulsion polymerization procedure at a temperature of not higher than 100.degree.C in a specified amount of water and then adding a basic dye to the resulting polymer solution or emulsion, or : carrying out this solution or emulsion polymerization in the presence of a basic dye. The aqueous polymer is useful as an aqueous ink such as an ink for the ink jet recording.
