Holographic recording materials based on photopolymerising systems have contributed significantly to the recent growth of holography. Of the available materials for holography, photopolymer is proved to be highly versatile due to its rapid dry processing, low cost, high optical quality and resolution, low diffusivity, easy preparation techniques, high diffraction efficiency, transparency in the visible spectral region etc. However, availability of commercial grade photopolymer material is very limited due to its strategic importance. On the other side, there are a set of research grade materials widely available. But, a major obstacle for the wider use of such materials is the short shelf life and storage life. The paper presents the shelf life and storage life studies of a laboratory made polymeric mixture which is sensitive to blue wave length. The material yielded stable quality and efficiency for over three months.
