Abstract
598,361. Compound sheet materials. SARGENT, E. H. G. Jan. 19, 1945, No. 1585. [Class 140] In making compound sheet materials by hot-pressing superposed layers of cellulosic fibrous material impregnated or coated with a thermosetting synthetic resin such as phenol- or cresol-formaldehyde, the fibrous layers are made waterproof, before treatment with the resin, with the aid of a quaternary ammonium compound, sulphonium compound, or phosphonium compound.
