Abstract
The present invention provides a photosensitive material having a support, a layer containing opacifying agent, a layer containing microcapsules and a layer of developer material. The layer containing opacifying agent, the layer containing microcapsules and the layer of developer material are positioned such that upon rupturing the microcapsules, the color former diffuses to the developer material layer to form an image in the developer material layer. The final image is viewed against the opacifying agent.
