A new recorder material with the ability to store information by pressure and temperature parameters, computer phase holograms were obtained whit this material, which it is used a coating of polyester resin mixing with nitrocellulose. The major improvements from our material are: high diffraction efficiency (91.9 %), reduced cost, easily to apply on any substrate and the hologram is making with out develop process, and this does not need carefully controlled environment conditions. In this approach the hologram is formed under pressure and temperature.
