DEFINITION

Classification: 430/202

Diffusion transfer process, element, or identified image receiving layers therefor:

(under subclass 199) Processes wherein the image is formed in and/or on the image receiving layer by permeation of a nongaseous material from a radiation-sensitive layer in conjunction with and during the processing, e.g., exposure, developing, fixing, etc., of the radiation-sensitive layer. Also included are the element and identified image receiving layers for the above process.
