Light induced polymerization reaction “photopolymerization” is employed in quite different technical applications that have become beneficial to humans. These applications include microelectronics, information technologies, optical fibers, dental materials, printing inks, paints, varnishes, …1,2. Among these applications, photopolymer materials have revealed to be the best choice for holographic recording, promoting holography as a compelling choice for next-generation data storage needs.3 In holography and display devices, photopolymers were developed primarily for display of single images due to the refractive index variations or relief profiles generated by an optical interference pattern.4 Compared to inorganic photorefractive materials, photopolymers have much higher sensitivity due to chemical amplification effects, large dynamical range, high versatility of the formulations. Additionally, this is a relatively low cost one step process.
