WIPO Patent Application WO/2022/070889
Kind Code:
A1
Abstract:
This resin composition contains: coated particles each composed of a core part containing a metal oxide and a coating layer that is disposed on the surface of the core part and that contains an aluminum hydrated oxide; and a resin. The metal oxide is represented by MxOy (M is at least one element selected from the group consisting of Ba, Ti, Sr, Pb, Zr, La, Ta, Ca and Bi. x and y are each a number determined on the basis of the stoichiometric proportion, in accordance with the valence of the metal element M.). When the particles contained in the resin composition are analyzed by XPS, the atomic ratio Al/(M+Al) is found to be 0.05-0.7.
