Abstract: PROBLEM TO BE SOLVED: To provide a radiation-sensitive variable refractive index composition for an optical material so that the refractive index of the material can be varied by an easy method, the difference in the varied refractive indices is sufficiently large, and a stable refractive index pattern and optical material can be obtained without depending on the succeeding use conditions. SOLUTION: The radiation-sensitive variable refractive index composition contains (A) a decomposable compound, (B) a non-decomposing compound having the refractive index lower than that of the decomposable compound (A), (C) a radiation-sensitive decomposing agent and (D) a stabilizer. By irradiating the composition with radiation through a pattern mask, the above component (C) and the component (A) in the irradiated part are decomposed to produce a difference in the refractive index between the irradiated part and the non- irradiated part to form a pattern having different refractive indices.

Abstract: PROBLEM TO BE SOLVED: To provide a radiation-sensitive composition undergoing a change in refractive index, which can realize a change in the refractive index of a material by a simple method, giving a sufficiently great difference in refractive index due to the change, and can give a refractive index pattern and an optical material that are stable independent of the service conditions thereafter. SOLUTION: The radiation-sensitive composition undergoing a change in refractive index contains (A) a decomposable compound, (B) a nondecomposable compound having a refractive index higher than that of the compound (A), (C) a radiation-sensitive decomposer and (D) a stabilizing agent. The irradiation of the composition with radiations through a pattern mask decomposes the components (C) and (A) at the irradiated part to produce a difference in refractive index between the irradiated part and the unirradiated part, thus forming a pattern different in refractive index.
