PURPOSE:To increase the ink gloss of a multicolor printing section, and improve the colorfulness of a printing rule line section by mainly comprising kaolin clay and a water-soluble high molecule in a white pigment layer in a color former sheet, in which the white pigment layer is formed onto the surface of a support such as paper and an electron donative pigment is incorporated into a rear and which is coated with microcapsules. CONSTITUTION:In a color former sheet, in which a white pigment layer is formed onto the surface of a support such as paper and electron donative dyes are incorporated into a rear and which is coated with microcapsules, the white pigment layer uses kaolin clay and water-soluble high molecules (such as starch) as main components. Kaolin clay is employed in 50-95wt.% of the pigment layer and titanium dioxide in 5-30wt.%. Accordingly, the ink gloss of a multicolor printing section is increased extremely, and the colorfulness and visibility of a printing rule line section are improved largely. |
