Abstract
There are provided an inorganic film in which the light transmittance is not decreased also when the inorganic film is laminated on organic material such as a resin, and a laminate. An inorganic film 13 which comprises a refractive index gradient film 13a having a refractive index changing continuously from n1 to n2 (n1<n2) and being a functional film; and a refractive index gradient film 13b having a refractive index changing continuously from n3 to n4 (n4<n3) and being a functional film, and in which further, a difference between n2 and n3 is 0.1 or less.
Claims7
An inorganic film comprising a refractive index gradient film A being composed of an inorganic material, having a refractive index changing continuously from n1 to n2 from one surface toward the other surface, and wherein n1<n2 and being a functional film;
- and a refractive index gradient film B being composed of an inorganic material, having a refractive index changing continuously from n3 to n4 from one surface toward the other surface, and wherein n4<n3 and being a functional film;
- the refractive index gradient film B being laminated on a surface of the refractive index gradient film A on a side where the refractive index is n2 with a surface side where the refractive index is n3 being in direct or indirect contact with the surface of the refractive index gradient film A;
- a difference between n2 and n3 being 0.1 or less;
- the inorganic material being a complex oxide comprising Zn, Sn, and at least one of Si and Al.
