Abstract
A paper, board or non-woven product containing a fiber layer containing cellulosic fibers, plant fibers or other material suitable for making a paper, board or non-woven product. One surface of the fiber layer is treated with pigment particles. The web is treated with microscopic particles whose average size is so small as to permit the particles to adhere to each other by van der Waals forces.
