摘要： The invention provides a transparent-film-forming composition containing at least one microparticle-form inorganic substance having a refractive index of 1.80 or higher and lower than 3.00 (ingredient A), at least one microparticle-form inorganic substance having a refractive index of 1.55 or higher and lower than 1.80 (ingredient B), and a binder having a refractive index lower than that of the ingredient B, and preferably, a dispersion stabilizer, and being capable of forming, on a surface of a transparent substrate, a transparent film having excellent transparency and free from interference-related disturbance. The invention also provides a transparent-film-layered product having a transparent substrate and, on a surface of the substrate, a transparent film formed from the composition, which layered product exhibits a difference in refractive index between the transparent substrate and the transparent film of 0.03 or smaller and excellent transparency, and providing minimized interference-related disturbance.
