(under subclass 85) Product in which the claim defines (1) the elements* or constituents* which form the filamentary material or (2) the ingredients which compose the adhesive associated with the web, sheet or layer.
(1) Note. Only a single ingredient or constituents* need be recited to qualify for this subclass, but must be specifically recited. Thus: a synthetic fiber* is not sufficient for placement in this subclass, but polyamide* or polyester* is sufficient; cement* or glue* does not qualify, but casein adhesive does.
