Abstract
A photohardenable thermoplastic stratum containing a thermally activated blowing agent may be used to record images by imagewise exposing the stratum to actinic radiation adapted to polymerize and harden the stratum image-wise, and heating the exposed stratum to soften the unhardened areas and decompose the blowing agent, whereby a positive image of microscopic bubbles is formed in said stratum.
