Our research group has developed a new photopolymer which may be used as a holographic recording material. It is easy to prepare in layers of the desired thickness and has a lower potential toxicity than conventional materials. It is characterized by being environmentally friendly, since it does not contain any petroleum-derived solvents or other components classified as toxic, biotoxic, explosive, radioactive, oxidising, corrosive, inflammable or environmentally hazardous, and no such substances are used to prepare it. The only solvent used is water, thus minimizing any risk of contamination and, at the end of its useful life, it is easy to recycle in aqueous phase. It is possible to automatize all the stages of its preparation, and it enables holograms to be obtained in a single stage without the need for subsequent processing. We are looking for companies interested in acquiring this technology for its commercial exploitation. Innovative aspects: • Due to its characteristics and the fact that during the preparation process, its useful life and subsequent elimination, water is the only solvent used, the negative impact of this material on the environment is minimized. • It does not contain any components classified as toxic, biotoxic, explosive, radioactive, oxidising, corrosive, inflammable or hazardous for the environment. • Although the fabrication process is totally safe for workers, it is possible to automatize all the stages, thereby reducing the production costs. • Layers of different thicknesses may be easily obtained and they may be used at different wavelengths.
