    摘要: The object of the present invention is to provide red synthetic mica, which develops light-resistant red color closer to color of human skin and ultraviolet ray, and also to provide a method for manufacturing the same and an ultraviolet ray screening agent containing said synthetic mica.
    The synthetic mica of the present invention is characterized in that, it is expressed by the following formula (I):



            X 1/3∼1 Y 2∼3 (Z₄ O₁₀) F 2×0.75∼2×0.99    (I)



    (where X represents one or more types of ions selected from a group of Na, K, Li, Ca, Rb and Sr, Y represents one or more types of ions selected from a group of Mg, Fe, Ni, Mn, Al, Li, Co, Ti and Zn, Z represents one or more types of ions selected from a group of Al, Si, Ge, Fe, B, Co and Ti, and at least one of Y and Z represents an iron ion), molar number of iron contained in said synthetic mica is 0.01 to 3 mols, and, when said synthetic mica is measured by powder cell method, its color is given by L* = 55 to 75, a* = 5 to 20, and b* = 5 to 20 by the CIE 1976 (L*a*b*) space.
