DEFINITION

Classification: 44/573

With resin or organic -C(=O)O- compound (e.g., rosin, tall oil, tallow, pine resin, carboxylic acid esters, etc.):

(under subclass 572) Subject matter wherein the consolidated solid fuel composition also contains a resin or an organic -C(=O)O- compound as a component.

(1) Note. The resin or organic-C(=O)O-compound normally, but not necessarily, serves a binding function.

(2) Note. The term "resin" is intended to include all material identified as unspecified resin, all natural resins, and synthetic resins not prepared by polymerization or copolymerization of a specified monomer or specified monomers.

(3) Note. An organic -C(=O)O- compound is one in which the carbon of the -C(=O)O- group is, or is attached directly or indirectly by nonionic bonding to, the carbon of an organic compound.

(4) Note. See Glossary in the class definition for the definition of "organic compound".
