  • Patent number: 6582501
    Abstract: An ink composition for ink-jet printers is provided which includes a chromophore, a solvent, a co-solvent, a humectant, a surfactant, a viscosity adjuster and an additive. The additive is a nitrogen-containing heterocyclic compound. This nitrogen-containing heterocyclic compound has the hydroxy groups which improve miscibility with water, thereby preventing clogging of nozzles during use. The present invention increases the affinity for dye used as a chromophore and for the hydroxy groups of paper after discharging of ink, which allows the chromophore to easily fix on the paper, thus enhancing smearfastness of the ink composition after printing.

  • Patent number: 6454842
    Abstract: A method of preparing a scented ink composition comprising the steps of first preparing a mixture which includes a polymer component consisting of a water soluble polymer selected form the group consisting of acrylic, styrene-maleic anhydride, sulfonated polyester, polyamide, and polyurethene. A color component which is selected from the group consisting of a pigment and a dye, and a solvent component comprising water are also provided. The mixture is then agitated. An oil-based fragrance is then blended into this mixture to produce a scented mixture and is then agitated. A microemulsion of the oil-based fragrance in water is created, wherein the resin stabilizes the microdroplets of the oil-based fragrance by coating the microdroplets. Preferably, the microdroplets of the oil-based fragrance have a diameter of from about 0.1 to about 1.0 micrometers.

  • Patent number: 6352584
    Abstract: This invention relates to washable coloring compositions comprising specific low-molecular weight styrene-maleic anhydride copolymers. Such copolymers provide excellent washability enhancing performance in association with colorants and inks. Also, these specific compounds exhibit low viscosities which allow for greater amounts of washability enhancing copolymers to be added within colorant and ink formulations while simultaneously permitting the retention of sufficiently low overall viscosities of the target compositions. Such copolymers provide highly effective prevention of permanent colorations to certain substrates, such as skin, clothing, and the like, by the inks, dyes, and the like, within the target compositions. Marker styluses, writing implements, and other colorant transfer devices, containing these inventive compositions, are also encompassed within this invention.
