PROBLEM TO BE SOLVED: To provide an aqueous dispersion suitable for priming a glasslike substrate, a mineral substrate in particular. SOLUTION: This priming method of mineral substrate comprises a process of applying an aqueous dispersion of composite particles to the mineral substrate. The dispersion is obtained by free-radical emulsion polymerization of a mixture of ethylenically unsaturated alkoxy silane monomer comprising addition polymer and finely particulate inorganic solid, and containing at least one kind of ethylenically unsaturated alcoxy silane monomer, in the presence of the finely particulate inorganic solid dispersely distributed in an aqueous medium and at least one kind of dispersion.
