    Abstract: An ink-jet ink is disclosed which comprises polymer-dispersed pigment particles in a liquid vehicle, wherein the polymer has an acid number of at least about 175 and comprises polymer molecules having anionic groups and hydrogen bond-forming groups. The anionic groups and the hydrogen bond-forming groups are configured on each of the polymer molecules to permit association of the anionic groups with cationic groups on a print medium, and to also permit the hydrogen bond-forming groups on neighboring polymer molecules to interact pair wise with each other, as the liquid vehicle dries and/or is absorbed into the medium.

    Abstract translation: 公开了一种在液体载体中包含聚合物分散的颜料颗粒的喷墨油墨，其中聚合物的酸值至少为约175，并且包含具有阴离子基团和形成氢键的基团的聚合物分子。 在每个聚合物分子上配置阴离子基团和氢键形成基团以允许阴离子基团与印刷介质上的阳离子基团缔合，并且还允许相邻聚合物分子上的形成氢键的基团相互作用 当液体车辆干燥和/或被吸收到介质中时，彼此之间是明智的。

    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.
