    摘要： A capsulated colorant including a colorant and a polymer resin which is coated on the colorant and has a cross-linked structure, a method of preparing the capsulated colorant, and an ink composition including the capsulated colorant. By adjusting the extent of cross-linking of the colorant on which the polymer having a cross-linked structure is coated, a capsulated colorant having a cross-linking of larger extent and a capsulated colorant having a cross-linking of smaller extent are obtained. By using an ink composition including the capsulated colorant having a larger cross-linked extent, characteristics of excellent waterfastness, lighffastness, rubfastness and optical density can be realized. In addition, by using the ink composition including the capsulated colorant having a smaller cross-linked extent, images with excellent durability and printed gloss can be realized.

    摘要： The present invention provides both crosslinked polymer compositions capable of forming hydrogels upon exposure to an aqueous environment and thiosulfonate hydrogel-forming components. The thiosulfonate hydrogel-forming components of the invention are preferably multi-arm thiosulfonate polymer derivatives that form a crosslinked polymer composition when exposed to a base without requiring the presence of a second cross-linking reagent, redox catalyst, or radiation. Methods for forming hydrogel compositions, as well as methods for using the hydrogels, are also provided.
