RADIATION SENSITIVE REFRACTIVE INDEX CHANGING COMPOSITION

摘要

A radiation-sensitive composition capable of having a refractive index distribution which comprises (A) a decomposable compound, (B) a non- decomposable component containing inorganic oxide particles and (C) a radiation-sensitive decomposing agent; and a method for forming a refractive index pattern or an optical material which comprises irradiating the above composition with a radiation and then treating the resulting product with (D ) a stabilizer. The method allows the preparation, with ease and simplicity, o f a refractive index pattern or an optical material having a refractive index distribution including satisfactorily great refractive index change and bein g stable independently of the conditions wherein it is used.
