Abstract
An artificial green colorant, composed by erioglaucine (Blue 1) and tartrazine (Yellow 5), was employed in a sugar matrix to improve the material sensibility and to make a comparative analysis of the diffraction efficiency parameter, for holograms replications, the holographic pattern was obtained by a computer and recorded in sugar films and in modified sugar (sugar-colorant). Conventional lithography and UV radiation were used. The results show that the behavior diffraction efficiency of the sugar-colorant films is slightly larger than in the sugar matrix under the same recording conditions.
