Abstract
A process is disclosed for coating paper with a novel water-soluble thermosetting resin, which has the property of providing paper with a nearly constant wet and dry strength over a wide pH range; the resin can be mixed, if desired, with other water-soluble polymers such as starch, its derivatives, cellulose derivatives, polyvinylalcohol and polyacrylamide, and various pigments such as clay, calcium carbonate and titanium dioxide.
