To obtain an ultraviolet-screening material capable of inhibiting the photocatalyst function which the conventional ultraviolet-screening materials additionally possess and exhibiting ultraviolet-screening function alone without light-aging the organic base material having been added and dispersed in the ultraviolet-screening material, and to provide a method for preparing the same.

Ultraviolet-screening materials are obtained by coating an ultraviolet-screening functional substance with a clay mineral. A method for preparing the ultraviolet-screening material comprises the steps of (a) dispersing a clay mineral in a dispersion medium to prepare a clay mineral dispersion; (b) mixing an ultraviolet-screening functional substance into the clay mineral dispersion; (c) subjecting the resulting mixture to solid-liquid separation; and (d) heating the solids content obtained in step (c).
