A method for modifying the surface of a synthetic fibrous sheet material comprises applying to its surface a watersoluble polymer that is photoinsolubilizable, has a molecular weight from about 10,000 to about 4,000,000, and is selected from the group consisting of polysaccharides and aliphatic derivatives of polysaccharides, polyvinyl alcohol, polyacrylic acid, pectin and polyethylene oxide, and optionally an abrasive material that is at least partially transparent to ultraviolet light, drying and curing by irradiation. The modified surface can be marked with ink pen and printing equipment. In a preferred embodiment silica is present in the applied composition.
