DEFINITION

Classification: 162/157.2

Synthetic resin:

(under subclass 157.1) Processes and products in which the fibers consist of synthetic resin, that is, complex organic compounds produced from ingredients which are nonresinous in themselves and which compounds simulate natural resins in that they are usually adapted for forming films or fibers or for use as binders in plastic compositions.

(1) Note. Fibers which are primarily carbohydrates or derivatives thereof are excluded from this subclass or subclasses indented hereunder.
