DEFINITION

Classification: 525/501.5

Mixed with reactant which is a fatty acid glycerol ester, a fatty acid or salt derived from a naturally occurring glyceride, tall oil, or a fatty acid derived from tall oil; or the reaction product of any of the above with a polycarboxylic acid or ester forming derivative and a polyhydroxy compound:

(under subclass 480) Subject matter wherein there is at least one reactant which is a fatty acid glyceride, a fatty acid or salt thereof derived from a naturally occurring glyceride, tall oil, or a fatty acid derived from tall oil, or a reaction product of any of these materials with a polycarboxylic acid or ester and a polyol.

(1) Note. The so-called drying or semidrying oil modified phenolic resins are placed herein if an unsaturated fatty acid or oil is added to a solid polymer or preformed SICP.

(2) Note. Dehydrated castor oil fatty acids are included herein as fatty acids derived from a naturally occurring glyceride.

(3) Note. See Lines With Other Classes and Within This Class, section II, B(5) for a discussion of the lines between this subclass and other areas.
