DEFINITION

Classification: 525/8

ETHYLENICALLY UNSATURATED REACTANT ADMIXED WITH A PREFORMED REACTION PRODUCT DERIVED FROM: (A) AT LEAST ONE POLYCARBOXYLIC ACID, ESTER, OR ANHYDRIDE; (B) AT LEAST ONE POLYHYDROXY COMPOUND AND; (C) AT LEAST ONE NATURAL RESIN, PROTEIN OR BIOLOGICALLY ACTIVE POLYPEPTIDE, OR CARBOHYDRATE OR DERIVATIVE:

(under subclass 1) Subject matter under Class 520, ... wherein an ethylenically unsaturated reactant is admixed with a preformed polyester formed from a polyol; polycarboxylic acid, ester, or anhydride; and a natural resin, protein, biologically active polypeptide, carbohydrate, or derivative.
