PROBLEM TO BE SOLVED: To make more of a silane compound adhere on the pigment powder surface than by conventional methods. SOLUTION: A silane compound represented by formula (1): (RC<SB>n</SB>H<SB>2n</SB>)<SB>a</SB>Si(OC<SB>m</SB>H<SB>2m+1</SB>)<SB>b</SB>, a metal salt and a pigment powder are mixed and dispersed in a mixed solvent of a 1-4C alcohol and water to surface treat the pigment powder with the silane compound, wherein R is a 3-21C hydrocarbon, a polyether group or a perfluoroalkyl group; the groups may have a functional group such as an amino group or a hydroxyl group in the chain length, have a straight chain or branched chain, and may have a single chain length or a multiple chain length; n is an integer of 1 to 12, and m is an integer of 1 to 3; and a and b are each an integer of 1 to 3, and a+b=4.
