DEFINITION

Classification: 524/77

Natural resin or modified forms thereof other than rosin or its modified forms DNRM, e.g., shellac, dammar, etc.:

(under subclass 1) Subject matter wherein a solid polymer or specified intermediate condensation product is admixed with a designated nonreactant material which is a natural resin and is other than a rosin or a modified form thereof, e.g., shellac, dammar, copal, etc.

(1) Note. The material "vinsol" is included herein as a natural resin since rosin has been separated from the resinous pinewood extract which is the raw material. Wood tar, wood pitch, or pine tar are excluded herefrom unless disclosure specifically denotes these materials as being resinous.

SEE OR SEARCH THIS CLASS, SUBCLASS:

78, for wood tar, wood pitch, or pine tar not disclosed as being resinous.

270+, for rosin or tall oil as a DNRM, e.g., colophony, abietic acid, etc.

485, for a DNRM which is turpentine, turpentine oil, oil of turpentine, or spirits of turpentine.
