  • these improved mirrors have poor chemical resistance, particularly acid resistance, as compared to conventional mirrors having a backing coating layer using a lead-containing coating composition. This is probably because the water permeability increased and the chemical resistance deteriorated as a result of suppressing the amount of the epoxy resin component in the coating film in order to obtain corrosion resistance, workability and durability.
  • the back surface protective film contains a pigment (P ) And binder (B) consisting of 40 to 85 parts by weight of epoxy resin and hardener and 15 to 60 parts by weight of ketone formaldehyde resin and its derivatives (PZB) is 1.2 to 4.
