DEFINITION

Classification: 430/616

Composition for visible imaging by radiation only:

(under subclass 564) Subject matter containing a radiation sensitive material for use in processes wherein exposure to radiation of the product results in a visible image without the necessity of a separate chemical development step.

(1) Note. Included are compositions which provide visible images directly upon imagewise exposure as well as compositions wherein a latent image is developed by further exposure to radiation.
