Abstract
It is an object of the present invention to provide a novel imidazole alcohol compound that adheres strongly to metal surfaces in metal products, especially copper, aluminum and steel products, and that has a superior rust-preventive effect even in a thin film, and a surface-treating agent using the same. The novel imidazole alcohol compound is expressed by the following general formula (1) show a rust-preventive effect.(In general formula (1), R1, R2 and R3 are each hydrogen, a vinyl group or an alkyl group with 1 to 20 carbon atoms, an aromatic ring may be formed by R2 and R3, X indicates hydrogen, an alkyl group with 1 to 6 carbon atoms, or a substituent group which may contain N or O, m indicates an integer from 0 to 20, and n and l indicate integers from 1 to 3.) The above-mentioned imidazole alcohol compound can be produced by reacting an imidazole compound and an epoxy alcohol compound.
