Abstract
The present invention is directed to a water-resistant, aqueous base-dispersible article which comprises a pulp-filled binder, one of which is an ethylenically unsaturated carboxylated (e.g. acrylic) polymer soluble in base, the other of which is water-resistant. Accordingly, the pulp can be water-resistant while the binder is base-dispersible or the converse can be true. Cellulosic and polymeric pulp are ideally suited for filling an base-soluble acrylic polymer. Water-soluble resins can be incorporated into the article for controlling the properties for special purposes. The method for forming such an article comprises yet another aspect of the present invention.
