FIELD: polymer materials. SUBSTANCE: composition contains: transparent non-hardened polymer resin; 20-40%; special-purpose additives, 40-60%; and filler, the balance; consisting of dendrite-shape particles and prepared from hardened polymer resin with special-purpose additives. When preparing filler, mixture of the second polymer resin with special-purpose additives is stepwise hardened: it is first hardened to rupture elongation 300- 350%, then ground on centrifugal mill at rotation speed 12-1400 rpm, and finally hardened to form dendrite-shape particles. EFFECT: improved esthetic perception of decorative material. 4 cl, 5 dwgt
