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.
Claims20
A radiation sensitive refractive index changing composition, comprising:
- (A) a decomposable compound, (B) a non-decomposable component containing inorganic oxide particles, and (C) a radiation sensitive decomposer,
- wherein the relationship between the refractive index nA of the component (A) and the refractive index nB of the component (B) satisfies either one of the following expressions (1) and (2):
- nB−nA≧0.05 (1)
- nA−nB≧0.05 (2).
