DEFINITION

Classification: 430/332

DYE IMAGE FROM RADIATION SENSITIVE DYE OR DYE FORMER BY DRY PROCESSING, COMPOSITION, OR PRODUCT:

(under the class definition) Subject matter wherein a radiation sensitive dye or dye former in a medium is imaged with electromagnetic radiation to produce a print out dye image, bleach out dye image, or latent image which is developed to a visible image by dye processing, e.g., photochromic dyestuff, print out dyestuffs, photo bleachable dyestuff, leuco dyestuffs, etc., also radiation sensitive composition and product used in the process, and process of making the same.

(1) Note. A dye for the purpose of this and indented subclasses is any colored (including black) organic compound.
