DEFINITION

Classification: 524/270

Rosin or tall oil or modified forms thereof as DNRM, e.g., colophony, abietic acid, ester gum, etc.:

(under subclass 81) Subject matter wherein the organic designated nonreactant material is a compound containing an abietyl or modified abietyl moiety, e.g., rosin ester, metal salt of rosin, colophony, etc.; or is tall oil or a modified form thereof.

(1) Note. Rosin is the distilled or extracted residue from the exudation of certain species of pine, and its principal constituent is abietic acid.

(2) Note. This subclass includes tall oil which contains abietic acid and fatty acids.

(3) Note. All abietyl or substituted abietyl moieties are considered as being modified forms of rosin and as such are properly classified herein.

(4) Note. Abietyl as used herein includes the modified, e.g., hydrogenated, etc., as well as the nonmodified abietyl ring compounds.
