Decorated sheets on the basis of cellulose non-woven fabrics, such as paper, for the production of decorated laminates are impregnated with synthetic resins. Consequently, their sizes are changed, they become brittle and are not water-resistant in the laminate. In the method according to the invention the printed or unprinted non-woven fabrics are impregnated with an aqueous dispersion of a polymer which is cross-linkable by UV radiation, dried and optionally printed and finally irradiated with UV radiation. The decorated sheets thus obtained are water-resistant in the laminate and can be coiled up and stored after each process step.

A sheet is treated with a treatment to make paper dissolve in water. The sheet is cut into various shapes to make confetti. The confetti are used near water. Once in water, the confetti dissolves according to the treatment. The dissolved confetti do not block sunlight or cause problems with the water.

Release base papers with improved surface properties and more efficient manufacturing potential are made using cellulose nanofibrils (CNF) along with high freeness, less refined pulp. Release papers serve as the backing for common adhesive labels, for industrial film coatings, and also for certain food processing uses. The CNF may be added to the furnish and processed to paper, or the CNF may be added as a coating onto a partially dried web of paper. The CNF may optionally be combined with a starch and a starch crosslinker.

The present invention provides tissue webs and products having improved z-directional properties. The improved z-directional properties may be achieved by providing the structure with a unique three-dimensional surface topography, which increases the structure's Exponential Compression Modulus (K) and Caliper Under Load (C.sub.0). By improving both K and C.sub.0, the present inventors have also been able to provide tissue structures with relatively high Compression Energy (E), which enables the structures to be calendered at high loads without significant loss of sheet bulk or degradation of strength.
