摘要：
To provide a back coating composition capable of forming a back coating film which is scarcely susceptible to acid erosion, has good appearance and is excellent in water resistance, and a mirror excellent in acid resistance, outer appearance of the back side and water resistance. A back coating composition for forming a back coating film 14 on the back side of a mirror 10, which comprises a thermosetting resin, a pigment, a dispersant and a reactive silicone oil, wherein as the thermosetting resin, an epoxy resin (excluding a reactive silicone oil having epoxy groups) and an amine-type curing agent are contained, as the dispersant, an amino group-containing polymer having an amine value of at least 20 mgKOH/g and having no acid group, is contained, and as the reactive silicone oil, an epoxy-modified silicone oil having epoxy groups and having no polyoxyalkylene chain, is contained. A mirror having a back coating film formed by using the back coating composition.
