FIELD: optical holography. SUBSTANCE: phototermoplastic carrier consists of the backing and photosensitive layer containing polymeric photoconductor poly-N-epoxypropylcarbazole or copolymer of N-epoxypropylcarbazole with glycidyl ester of the general formula (image) with molecular mass 800-900 a.e.m. where x 0-0.14; n 3-5; R . Sensibilizing agent: 2,7-di-n-undecylhydroxycarbonyl-4,5-dinitro-9-dicyanomethylfluorene of the formula (image) at concentration 5-12% of polymeric photoconductor mass. Material shows holographic sensitivity Sn 1% 15-27 m2/J at λ 750 nm, diffraction effectiveness hmax 20-25% and a value of "parasitic memory" 0.8-1.5% EFFECT: enhanced quality of carrier. 1 dwg, 1 tbl
