FIELD: light-sensitive materials.
SUBSTANCE: invention relates to emission-sensitive composition with refractory index varied by emissions, which composition contains: (A) acid-decomposable compound; (B) acid-resistant compound having higher refractory index than acid-decomposable compound A; (C) emission-sensitive decomposing agent representing emission-sensitive acidifier; and (D) stabilizer. Amounts of each components A - C varies from 10 to 90, from 10 to 90, and from 0.01 to 30 wt parts, respectively. Amount of component D is 10 wt parts for 100 wt parts of component A. Invention also relates to ways for obtaining structure with refractory index distribution and to optical material.
EFFECT: enabled preparation of composition having above defined optical characteristics and of stable optical material.
