DEFINITION

Classification: 525/7

ETHYLENICALLY UNSATURATED REACTANT ADMIXED WITH A PREFORMED REACTION PRODUCT DERIVED FROM: (A) AT LEAST ONE POLYCARBOXYLIC ACID, ESTER, OR ANHYDRIDE; (B) AT LEAST ONE FATTY ACID GLYCEROL ESTER, A FATTY ACID OR SALT DERIVED FROM A NATURALLY OCCURRING GLYCERIDE, TALL OIL, OR A TALL OIL FATTY ACID:

(under subclass 1) Subject matter under Class 520, ... which are polyester-unsaturated reactant mixtures wherein (a) the polyester is prepared from a polycarboxylic acid, ester, or anhydride, and a polyol, and at least one fatty acid glycerol ester, a fatty acid or salt derived from a naturally occurring gylceride, tall oil, or a fatty acid derived from tall oil, and (b) there is at least one unsaturated reactant other than solely fatty glyceride, an unsaturated fatty acid or salt derived from a naturally occurring fatty glyceride, tall oil, or an unsaturated fatty acid derived from tall oil, or mixtures thereof.

(1) Note. Dehydrated castor oil or dehydrated castor oil fatty acids are treated as if they were unsaturated naturally occurring glyceride or unsaturated fatty acids derived from naturally occurring fatty glycerides.

(2) Note. A buffering agent to improve storage stability is regarded as a catalytic agent and therefore treated as specified material.
