Materials which undergo void stabilization for information recording must have the following characteristics: (1) be coated and processed in such a manner as to produce voids by solvent evaporation; (2) undergo a melt flow phase after solvent evaporation; and (3) be photosensitive in order to crosslink upon exposure and stabilize voids through an increase in viscosity or resistance to flow. The exposed areas containing the voids can then be filled with a dye to increase the signal-to-noise ratio and contrast for image reproduction, if needed.
