DEFINITION

Classification: 524/231

Two or more organo N-C=O compounds DNRM or with nonreactant organo nitrogen compound DNRM:

(under subclass 230) Subject matter wherein the N--R compound is in admixture with another designated nonreactant material which is organic and contains at least one nitrogen atom.

(1) Note. Included herein are mixtures of two or more N--R compounds or the admixture of one N--R compound and a diverse nonamide organo nitrogen compound.
