A humidity-resistant highly sensitive holographic photopolymerizable dry film

A new humidity-resistant highly sensitive acrylamide-based photopolymeric holographic recording material has been developed. The photopolymer is resistant to the humidity of environment. Diffraction efficiencies near 50% are obtained with exposure energy of 60 mJ/cm(2) in materials of 150 mu m. thickness. Diphenyl iodonium chloride is added to the material and can increase the exposure sensitivity by a factor of more than 4 (to about 28 mJ/cm(2)). An image has been successfully stored in the material with a small distortion. (C) 2005 Elsevier B.V. All rights reserved.
