Abstract
A method of improving the sensitometric response of a photosensitive imaging media under various humidity conditions including the steps of providing a photosensitive imaging media including an imaging layer comprising a developer material and a plurality of microcapsules encapsulating a photohardenable composition and a color former; image-wise exposing the imaging media to actinic radiation to form a latent image on the media; maintaining the imaging media containing the latent image at an elevated temperature; and developing the image.
