PROBLEM TO BE SOLVED: To provide a powder of polyamide porous particles carrying inorganic compounds that has high light scattering characteristic and is safe for the human body.SOLUTION: A powder comprising polyamide porous particles carrying inorganic compounds is prepared by carrying a large number of inorganic compound fine particles on a surface of each polyamide porous particle having pores in its surface and carrying them in the pores. The polyamide porous particles have an average primary particle diameter of in a range of from 1 to 30 μm. The inorganic compound fine particles have an average primary particle diameter of in a range of from 0.01 to 0.5 μm, and 80% or more of the inorganic compound fine particles contains no strongly acidic component.COPYRIGHT: (C)2015,JPO&INPIT【課題】光散乱性が高く、また人体に対して安全な無機化合物担持ポリマー粒子の粉末を提供する。【解決手段】表面に細孔を有するポリアミド多孔質粒子の表面及び細孔内に、多数の無機化合物微粒子が担持されてなる無機化合物担持ポリアミド多孔質粒子からなる粉末であって、ポリアミド多孔質粒子の平均一次粒子径が1~30μmの範囲にあって、無機化合物微粒子の平均一次粒子径が0.01~0.5μmの範囲にあり、その80個%以上の無機化合物微粒子が強酸性成分を含むことがない粉末。【選択図】なし
