PROBLEM TO BE SOLVED: To provide an ultraviolet shielding composite particle that has a high UV-A shielding property though the content of a dibenzoylmethane derivative that is an ultraviolet shielding agent is low, and that can efficiently shield especially the ultraviolet in a long-wavelength side, and especially the ultraviolet on the wavelength band region of 380-400 nm, and to provide a dispersion and a cosmetic containing the ultraviolet shielding composite particle.SOLUTION: The ultraviolet shielding composite particle is characterized in that a resin composition that contains a dibenzoylmethane derivative in a second resin is made to adhere to the whole surface or one part of the surface of a core part consisting of a first resin to make a coating film or at least one island-like object, and the content of the dibenzoylmethane derivative is at least 20 mass% and at most 60 mass%.COPYRIGHT: (C)2013,JPO&INPIT【課題】紫外線遮蔽剤であるジベンゾイルメタン誘導体の含有率が低いにもかかわらず、高いUV-A遮蔽性を有し、特に長波長側の紫外線、特に380-400nmの波長帯域の紫外線を効率的に遮蔽することのできる紫外線遮蔽複合粒子及び紫外線遮蔽複合粒子含有分散液並びに化粧料を提供する。【解決手段】本発明の紫外線遮蔽複合粒子は、第1の樹脂からなる芯材部の表面全体または表面の1箇所以上に、第2の樹脂中にジベンゾイルメタン誘導体を含有してなる樹脂組成物を付着させて被覆膜または1個以上の島状物とし、この樹脂組成物中のジベンゾイルメタン誘導体の含有率を20質量%以上かつ60質量%以下とした。【選択図】なし
