DRY TYPE ELECTROSTATIC RECORDING COLOR TONER

PURPOSE:To obtain a dry type electrostatic recording functional color toner capable of forming an image having a sharp color unaffected by an underlayer color by adding a substance high in refractive index to raise a toner layer in hiding power. CONSTITUTION:This purpose is achieved by using a color toner composed essentially of a synthetic resin and a colorant, and contg. further, fine powder of a substance having >=1.6 refractive index and incompatible with this resin. White pigments having such indices and not impairing the color of the colorant are generally desirable, and it may be a colored inorg. pigment having a color resembling the used colorant. As the white pigment, e.g., rutile or anatase type titanium oxide, zinc oxide, antimony oxide, tin dioxide, zirconium oxide, zinc sulfide, lithopone, etc. are desirable, and they may be used alone or in combination. The use of titanium oxide high in refractive index is especially desirable. A preferable amt. of said substance contained in the color toner is 0.1-10wt. of the colorant.
