PROBLEM TO BE SOLVED: To provide a dispersion of core-shell composite oxide fine particles having high dispersion stability, a method for producing the dispersion, a coating composition containing the core-shell composite oxide fine particles, a curable coating film, and a curable coating film It is related with a base material with attachment. A core shell in which oxide fine particles or composite oxide fine particles not containing silicon and / or aluminum as a main component are used as core particles, and the surface thereof is coated with a shell made of a composite oxide containing silicon and aluminum as main components. When the content of silicon and aluminum contained in the shell of the fine composite oxide fine particles is in the range of SiO 2 / Al 2 O 3 = 2.0 to 30.0 in terms of the weight ratio of the oxide conversion standard, A highly stable dispersion of core-shell type complex oxide fine particles having a high charge amount and a covering ratio of the shell to the core can be obtained.
