Prepreg obtained from a decor base paper impregnated with a formaldehyde-free impregnating resin solution, whereby a hydrophobic coating is applied onto at least one side of the prepreg, and decorative film or decorative coating material containing the prepreg according to the invention.

An aqueous prepolymer composition, which comprises a polyacrylamide base polymer comprising 10 - 40 mol-% of cationic monomers and having a weight average molecular weight Mw in the range of 120 000 - 350 000 g/mol, 0.1 - 1 weight-% of glyoxal, calculated from the total weight of the aqueous prepolymer composition, and a buffering acid for adjusting pH of the composition in the range of 2 - 4. A prepolymer composition is used in a method for producing on-site glyoxylated polyacrylamide useful in paper or board manufacturing.

Provided is a moisturized tissue excellent in strength and snot wiping property. In the moisturized tissue paper, a paper thickness is 220 to 330 μm, a basis weight is 15 to 18 g/m.sup.2 per ply, a proportion of NBKP in the pulp combination is more than 70 mass %, a chemical solution content is 26 to 32 mass %, an arithmetic mean curvature at a peak point of an outer surface in an unpressurized state (Spc (1)) is 4.0 to 4.8 (1/mm), and a developed area ratio at an interface on the outer surface (Sdr) is 0.020 to 0.030 (−).

The present invention relates to a method for producing a film comprising nanocellulose, which method comprises: providing a suspension comprising 50-100 weight-% of nanocellulose based on total dry weight; forming a fibrous web of said suspension on a non-porous support; providing a press fabric comprising a web-side first surface and an opposite second surface, wherein said press fabric comprises a woven first fabric layer arranged in the press fabric as a layer providing said web-side first surface such that said press fabric has a woven surface structure at said web-side first surface; applying said web-side surface of said press fabric into direct contact with said web; wet-pressing said web by conducting said web, arranged between said press fabric and said non-porous support, through a pressing equipment, and drying the dewatered web so as to form said film. The invention further relates to a film produced from said method.
