    摘要: A process for making a leuco dye coating composition, comprising the steps of:

    A. blending a mixture of (a) a leuco Dye, (b) an antioxidant, (c) a [polypoly(ethyleneoxide)block-poly(propyleneoxide)] nonionic block copolymer surfactant, (d) an alkylarlyoxypoly(alkylene oxide) nonionic surfactant and (e) water;
    B. milling the blend prepared in step A to prepare a coating composition of the leuco dye in milling media;
    C. separating the dye coating composition from the milling media.
