To provide a coating film-forming composition capable of forming a coating film having excellent water repellency and also excellent wear resistance, a coating film, and a chemical solution.SOLUTION: The coating film-forming composition contains inorganic fine particles, a polymerizable component, and a water-repellent component. The inorganic fine particles include first inorganic fine particles having an average particle diameter of 1 nm or more and 100 nm or less, and second inorganic fine particles having an average particle diameter of 500 nm or more and 5 μm or less. The content of the first inorganic fine particles is 3-25 pts.mass per 100 pts.mass of the total mass of the first inorganic fine particles, the second inorganic fine particles, the polymerizable component and the water-repellent component. The content of the second inorganic fine particles is 12-27 pts.mass per 100 pts.mass of the total mass of the first inorganic fine particles, the second inorganic fine particles, the polymerizable component and the water-repellent component. The water-repellent component is a polymer having at least a structural unit based on a specific compound.SELECTED DRAWING: None 【課題】本開示は、優れた撥水性を有し、耐摩耗性にも優れる被膜を形成することができる被膜形成用組成物及び被膜並びに薬液を提供する。【解決手段】無機微粒子と、重合性成分と、撥水性成分とを含み、前記無機微粒子は、平均粒子径が１ｎｍ以上１００ｎｍ以下である第１の無機微粒子、及び、平均粒子径が５００ｎｍ以上５μｍ以下である第２の無機微粒子を含み、前記第１の無機微粒子の含有量は、前記第１の無機微粒子、前記第２の無機微粒子、前記重合性成分及び前記撥水性成分の総質量１００質量部あたり、３～２５質量部であり、前記第２の無機微粒子の含有量は、前記第１の無機微粒子、前記第２の無機微粒子、前記重合性成分及び前記撥水性成分の総質量１００質量部あたり、１２～２７質量部であり、前記撥水性成分は、特定の化合物に基づく構造単位を少なくとも有する重合体である。【選択図】なし
