Abstract

There are provided a solvent composition containing tDCE, which does not exert an adverse effect on the global environment, has high solubility and incombustibility, and can maintain initial incombustibility even in use accompanied by a phase change, a cleaning method using the solvent composition, a coating film-forming composition including the solvent composition, and a method of forming a homogeneous coating film using the coating film-forming composition. A solvent composition includes: tDCE; at least one HFE (A) selected from HFE-347pc-f, HFE-365mf-c, and HFE-467sc-f; and at least one HFC (X) selected from cHFC-447, and HFC-76-13sf, in which a ratio of tDCE with respect to a total amount of tDCE, HFE (A), and HFC (X) is 65 to 80 mass %, a ratio of HFE (A) with respect to the total amount is 5 to 25 mass %, and a ratio of HFC (X) with respect to the total amount is 5 to 25 mass %.
