PROBLEM TO BE SOLVED: To provide an aqueous composition capable of forming a coating film which can maintain appearance or stain resistance at a high level.SOLUTION: There is provided an aqueous composition which comprises: polymer particles (A) containing a structural unit derived from dimethyl dimethoxysilane (a) in a ratio of 32 to 70 mass%; a polymer particle dispersant (AD) containing an octamethyl cyclotetrasiloxane (m) and/or a decamethylcyclopentasiloxane (n); and inorganic oxide particles (B), where the total amount of the octamethyl cyclotetrasiloxane (m) and the decamethylcyclopentasiloxane (n) is 0.01 to 0.9 pts.mass based on 100 pts.mass of the (A) component. |
