    摘要： A coated synthetic paper adapted for offset printing is produced from a base paper sheet comprising fibrous material, at least 5% by weight of which is formed of polyolefinic pulp fibrils which are formed from a polyolefinic polymer and a hydrophilic polymer, said polyolefinic pulp fibrils having a specific surface area of at least 0.7 square meter/g. A microporous and discontinuous coating layer is formed on at least one of the surfaces of the base paper sheet using a coating composition having an adhesive component and a pigment component, at least 5% by weight of said pigment component being an organic polymer pigment in the form of finely divided particles.

    摘要： A method of making a light-weight, wet-formed, print-bonded nonwoven fabric which comprises: (1) forming an aqueous slurry of fibrous materials; (2) transferring the aqueous slurry of fibrous materials to a fluid-permeable, moving, forming surface in the form of a wet, flat fibrous sheet having a fiber weight of from about 160 to about 800 grains per square yard; (3) removing water from the wet, flat fibrous sheet to bring the fiber weight into the range of from about 20% to about 35% by weight of the total weight of the wet, flat fibrous sheet; (4) transferring the wet, flat fibrous sheet to nonwoven fabric print-bonding rolls by passage through an open draw wherein the wet, flat fibrous sheet is conveyed unsupported through an open air gap; (5) applying an aqueous resin binder to the wet, flat fibrous sheet by printbonding rolls employing an etched or engraved printing surface, the aqueous resin binder being applied in an amount equal to from about 30% to about 160% of the weight of the fibers in the wet, flat fibrous sheet and having a resin solids content of from about 15% to about 60% by weight; (6) transferring the wet, flat fibrous sheet with the aqueous resin binder applied thereto to a carrier by passage through an open draw wherein the wet, flat fibrous sheet with resin binder applied thereto is conveyed unsupported through an open air gap; and (7) carrying the wet, flat fibrous sheet with resin binder applied thereto through a heated zone having an elevated temperature, whereby the resin binder is dried to bond the fibrous web into a self-sustaining, bonded nonwoven fabric wherein the resin binder content is in the range of from about 5% to about 45% of the weight of the bonded nonwoven fabric; and apparatus for carrying out such a method.
