Summary:PROBLEM TO BE SOLVED: To provide an aqueous dispersion of polyorganosiloxane particles which shows an excellent crack resistance at a dried state when used as a coating and also exhibits an excellent weather resistance, water resistance, stain resistance and adhesion, and its preparation process. SOLUTION: The aqueous dispersion of polyorganosiloxane particles is obtained by allowing a seed polymer particle (A) having a weight average molecular weight of from 500 to 30,000 to absorb a silane component (B) comprising at least one chosen from an organosilane, its hydrolysate and its condensate in an aqueous medium and subsequently subjecting it to a condition under which the silane component (B) is hydrolyzed and condensed.
