Abstract
A multilayer film is produced by forming a first and a second layers consecutively on at least one surface of a biaxially stretched polyester base. The first layer contains particles and a binder both composed mainly of either tin oxide, indium oxide, zirconium oxide, or titanium oxide. When the refractive indexes of the base, the first layer, and the second layer are represented by η, and ηrespectively, the first layer and the second layer are adjusted for the refractive index such that the differences |η| and |η| are both not greater than 0.03. Adhesive strength is therefore kept high between the base and the layers to eliminate light interference, and the multilayer film offers an excellent optical property with few color rainbow effect.
