    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 formulated at a basic pH so that a surface of each of the pigment particles carries a net negative charge; and the second colored ink includes pigment particles formulated at an acidic pH so that a surface of each of the pigment particles carries a net positive charge. The composite color exhibits enhanced color richness when printed on a substrate.

    Abstract translation: 复合颜色包括第一着色墨水和第二彩色墨水。 第一种有色油墨表现出与第二种有色油墨不同的颜色。 第一着色油墨包括在碱性pH下配制的颜料颗粒，使得每种颜料颗粒的表面带有净负电荷; 并且第二着色油墨包括在酸性pH下配制的颜料颗粒，使得每种颜料颗粒的表面带有净正电荷。 复合颜色在印刷在基材上时表现出增强的色彩丰富度。

    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.
