ABSTRACT:
A method of forming a refractive index pattern or an optical material stable regardless of use conditions, which provides a sufficiently large change in refractive index by a simple method. The refractive index pattern or optical material is formed by exposing a refractive index changing composition which comprises (A) a decomposable compound, (B) a non-decomposable compound containing inorganic oxide particles and (C) a radiation sensitive decomposer to radiation and then treating it with (D) a stabilizer.
