摘要：PROBLEM TO BE SOLVED: To obtain the subject fine particles excellent in hue stability by including a trialkoxysilyl group-containing pigment and an silicon alkoxide. SOLUTION: The particles having preferably <=10μm particle diameter are obtained by adding (A) 1 mol silicon alkoxide (e.g. at least one kind of silane compound selected from monoalkyltrialkoxysilanes and alkylsilicate dimers) and (B) <=0.4 mol trialkoxysilyl group-containing pigment to (D) an organic solvent containing water exceeding hydrolysis amount of 2-1,000 times based on total molar amount of the components A and B in the presence of (C) ammonium ion catalyst in a molar amount of 1-100 times based on total molar amount of the components A and B and subjecting the components A and B to cohydrolysis under stirring of the organic solvent.
