FIELD: optical materials.

SUBSTANCE: invention relates to radiation-sensitive compositions with variable refraction coefficients allowing novel model with refraction coefficient distribution to be obtained, in particular optical material used in optical electronics and information representation devices. Invention discloses emission-sensitive composition with variable dielectric permittivity containing decomposable compound (A), non-decomposable component (B) including inorganic oxide particles resistant to acid or base originated from acid or base source (C), and radiation-sensitive degradable substance (C), wherein refraction coefficient n_A of decomposable compound A and refraction coefficient n_B of non-decomposable compound B lie in one of following relationships: n_B-n_A ≥ 0.05 (1) and n_A-n_B ≥ 0.05 (2), amount of component B ranges from 10 to 90 wt parts based on 100 wt parts of summary amount of components A and B, and amount of component C ranges from 0.01 to 30 wt parts based on 100 wt parts of summary amount of components A and B. Model obtained from indicated composition allows one to vary in a simple way refraction coefficients thereby achieving sufficiently large difference between them and their stability irrespective of application conditions.

EFFECT: expanded possibilities in optical representation of information.
