Abstract

The pigmented ink jet inks became popular recently. But they are used knowing some limitation of color quality compared with dye-based inks. To elevate the pigment dispersion for ultimate ink jet colorant, the research for more sophisticated pigment dispersion and the cooperation of colorant, ink formulation and printing technology are essential.To improve the color reproducibility of pigmented ink for ink jet colorants, we did investigation for desired encapsulated pigment with water-insoluble polymer (encapsulated colorant). We found that the encapsulated colorant was improved color sifting in comparison with conventional colorants, water-soluble polymer dispersed colorant (conventional A) and dispersion dispersed colorant (conventional B), using the goniospectrophotometer. By reducing the ratio of pigment in colorant, color sifting could be improved, too. It seemed that the interfacial mechanism was thought suitable for color reproducibility in this study.
