    • Systems and methods for producing permanent ink-jet images are provided. In one embodiment, a system comprises a media substrate coated with a porous media coating, wherein the porous media coating comprises inorganic porous particulates, and wherein at least a portion of the inorganic porous particulates have a first reactive group covalently attached thereto. The system further includes an ink-jet ink containing a dye, wherein the dye comprises a second reactive group, and wherein the first reactive group and the second reactive group are configured to react with one another upon contact to form a covalent bond. In an alternative embodiment, a method of producing permanent ink-jet images can comprise the steps of covalently bonding a first reactive group to an inorganic porous particulate; coating the inorganic porous particulate onto a media substrate to form a coated media substrate; ink-jetting a dye-containing ink-jet ink composition onto the coated media substrate, wherein the dye includes a second reactive group. The first reactive group and the second reactive group, upon contact, can interact to form a covalent bond.
    • 提供了用于生产永久性喷墨图像的系统和方法。 在一个实施方案中,系统包括涂覆有多孔介质涂层的介质基材,其中多孔介质涂层包含无机多孔颗粒,并且其中至少一部分无机多孔颗粒具有共价连接到其上的第一反应性基团。 该系统还包括含有染料的喷墨油墨,其中所述染料包含第二反应性基团,并且其中所述第一反应性基团和所述第二反应性基团在接触时被配置为彼此反应以形成共价键。 在替代实施方案中,制备永久性喷墨图像的方法可以包括将第一反应性基团共价键合到无机多孔颗粒的步骤; 将无机多孔颗粒涂覆到介质基底上以形成涂覆的介质基底; 将含染料的喷墨油墨组合物喷墨到所述涂覆的介质基材上,其中所述染料包括第二反应性基团。 第一反应性基团和第二反应性基团在接触时可以相互作用以形成共价键。
