Dichromate gelatins are well known as good holographic materials. Now by doping this material with synthetic vanilla, a change in the spectral amplitude response is obtained. Due that the maximum absorption spectra from the dichromate ammonium is localized in UV region at λ = 390. With vanilla, the maximum spectral response is similar, exception for its optical density, reducing the exposure factor the order of 2 times. An important property with this mixture is the high resistance to humidity of the ambient. We have recorded some diffraciotn gratings, using the argon laser λ = 488 nm, which show good diffraction (grooves). A characteristic of the developed process is its simply, only using solution composed of water and isopropyl alcohol, this process takes approximately one hour.
