DEFINITION

Classification: 430/269

IMAGING AFFECTING PHYSICAL PROPERTY OF RADIATION SENSITIVE MATERIAL, OR PRODUCING NONPLANAR OR PRINTING SURFACE - PROCESS, COMPOSITION, OR PRODUCT:

(under the class definition) Processes wherein an image (a) is produced in an imaged medium based upon physical property (e.g., hardness, tackiness, solubility, swellability,

vaporization, refractive index) difference in the medium caused by the amount of type or radiation received by the medium, and when the physical property difference in the medium is not caused by the amount or type of radiation received by the medium, the image is finished or perfected as by developing or fixing, (b) formed in a medium is a nonplanar image, i.e., image areas of the medium are elevated or lowered relative to the rest of the medium, or (c) formed in a medium and is used as or to form a printing surface; radiation-sensitive composition and product used in the process; process of making the radiation-sensitive composition and product; or finishing or perfecting composition or product used in the process.
