Abstract: Colorants having pigment and dye components having improved chroma and good water and lightfastness are disclosed and described. A polymeric colorant can include a pigment having a polymer covalently attached thereto and a dye covalently attached to the polymer. A dispersant can be covalently attached to at least one of the pigment, the polymer, and the dye. By including both a pigment and a dye component in the polymeric colorant, improved chroma, waterfastness, and lightfastness can be realized. The dye and pigment components can be substantially the same color, or can have different colors, depending on the desired appearance. The polymeric colorants of the present invention are well suited to inclusion in ink-jet compositions, although many other applications are considered suitable for the instant polymeric colorants.

Abstract: A composite color includes a first colored ink and a second colored ink. The first colored ink exhibits a color that is different from that exhibited by the second colored ink. The first colored ink includes pigment particles either formulated at a basic pH so that a surface of the pigment particles carries a net negative charge or formulated at an acidic pH so that a surface of the pigment particles carries a net positive charge; and the second colored ink includes pigment particles either formulated at an acidic pH so that a surface of each of the pigment particles carries a net positive charge or formulated at a basic pH so that a surface of the pigment particles carries a net negative charge. The first colored ink and the second colored ink have opposite charges. The composite color exhibits enhanced color richness when printed on a substrate.

Abstract: Compositions and methods for forming color images on a substrate capable of development at desired wavelengths or energy levels are disclosed and described. The color forming composition can include a carrier system and a latent pigment with a pendent group, wherein the latent pigment is colorless or pale in color while the pendent group is attached, and wherein the latent pigment is convertible to a colored pigment upon removal of the pendent group. Alternatively, the latent pigment can have multiple states of conjugation where the latent pigment is colorless or pale in a first conjugation state, and colored in a second conjugation state. The color forming compositions are useful in forming images on a wide variety of substrates, such as optical disks.
