  • Patent number: 8859639
    Abstract: 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.
