A radiation sensitive refractive index changing composition whose refractive index of a material is changed by a simple method, whose changed refractive index difference is sufficiently large, and which can provide a stable refractive index pattern and a stable optical material regardless of their use conditions.
The radiation sensitive refractive index changing composition comprises (A) a polymerizable compound, (B) a non-polymerizable compound having a lower refractive index than the polymer of the polymerizable compound (A), and (C) a radiation sensitive polymerization initiator.
