We report the properties of a new polymer-guest photosensitive mixture based on two monomers with different properties as basic components. The material has been characterized by recording holographic gratings using a low power blue laser (405 nm) and a spectro-photometric technique to get the optical properties of the grating during and after recording. The detected grating shows a very high sensitivity (of the order of 10^3 cm/J) and a surprising "antishrinkage" phenomenon (red-shift of the Bragg reflection grating wavelength).
