Results of experiments on synthesis of a thick-layered light-sensitive material on the base of gel-like dichromated gelatin are presented. In these experiments, the coated layer of liquid dichromated was not subjected to drying but it was sealed between two glasses in order to be protected from drying. The recording was performed on moisture-saturated layers after the liquid was transformed into gel. The thickness of the layer varied from 1 to 3 mm. The maximum efficiency of transmission holograms recorded in the layer reached 17%. The sensitivity to the blue light ((lambda) equals 0.44 micrometers ) was about 10 J/cm 2 .
