138MICROCAPSULE, PROCESS, COMPOSITION, OR PRODUCT


DEFINITION

Classification: 430/138

MICROCAPSULE, PROCESS, COMPOSITION, OR PRODUCT:

(under the class definition) Subject matter wherein a preformed microcapsule, which is made prior to the manufacture of the product useful in radiation chemistry imagery, is added to the product, process of making and using the product, composition, or product.

(1) Note. The definition of microcapsule for this subclass includes any gas liquid or solid material which is completely surrounded by a different solid material with its largest dimension size being less than a few microns.

(2) Note. The use of microporous containing composition useful in processes under the class definition such as spongelike microporous structures or molecular sieves (zeolite) with/without absorbed or adsorbed ingredient therein are not subject matter for the subclass.

SEE OR SEARCH THIS CLASS, SUBCLASS:

31, for use of microcapsules in electric or magnetic imagery.

32, and 41, especially, for electrophoretic and migration imagery.

70, for radiation-conductive compositions in microcapsule form. 105, for developer compositions in microcapsule form; and appropriate product, process, and composition subclasses wherein (a) use of microcapsules is disclosed, but is an unclaimed feature; and (b) microporous compositions, products, and uses (see Note 2 above).
