(under subclass 125) Processes in which at least two layers are associated with different amounts or types of a nonfibrous organic material, and the products thereof.
(1) Note. The difference may reside in the fact that one layer is mixed with an organic material, while the adjoining layer is free of organic material. The organic material need not be specifically identified. It is sufficient if a functional term such as "sizing", indicative of the organic nature of the additive, is employed.
SEE OR SEARCH THIS CLASS, SUBCLASS:
158, through 180, for processes of adding nonfibrous organic material to a fiber slurry, pulp or wet web, and the resulting products.
