(under subclass 60) Processes in which the adhesive employed is specifically named or identified by composition thereof or chemical structure.
(1) Note. Patents in this and indented subclasses provide for use of specifically identified adhesives in a laminating operation involving no manipulative step provided for above. Individual compounds and compositions, per se, which may be disclosed to possess adhesive utility are classified on the basis of chemical structure or ingredients therein in Class 106, Compositions: Coating or Plastic, Class 260, Chemistry of Carbon Compounds and Class 423, Chemistry of Inorganic Compounds. Patents from these and other composition classes may be cross-referenced into these subclasses where a
laminating process is claimed or where a specific example in the specification is limited to laminating. The mere reference in the specification to the effect that a composition is a good adhesive is not sufficient to place a cross-reference in these subclasses.
SEE OR SEARCH THIS CLASS, SUBCLASS:
283+, for adhesives which are applied in particulate form.
309, for preformed intermediate layers or laminae which may be disclosed to have utility as a bonding agent between other dissimilar laminae.
SEE OR SEARCH CLASS 424, Drug, Bio-Affecting and Body Treating Compositions,
77, for an adhesive trapping composition.
428, Stock Material or Miscellaneous Articles, appropriate subclasses for a stock material product in the form of composite web or sheet, including a particular adhesive, and especially
355+, where the adhesive is the outermost layer and subclasses 411.1+ which provide for nonstructural plural layer products categorized by the composition of the respective layers, the adhesive employed between layers being considered as one of the layers.
