    摘要: A surface treatment composition for paper, board or other fibrous webs. The composition of the invention comprises particles which comprise an active material and a supporting material. The active material comprises a salt of a multivalent metal, such as a divalent or trivalent metal. In accordance with the invention, the supporting material is adapted to release the active material from the particles when subjected to heat and/or pressure and/or a change in pH. Consequently, the active material's adverse effects on the rheology of the composition are avoided while its desired effects on the surface characteristics are retained or enhanced.

    摘要: The invention comprises a method for producing identification marks (5) on layer-structured paper or board (7) to be manufactured in a continuous web and the marked papers and boards obtained with this method. With this method, the marks (5) are made with a laser beam on a moving web form fiber layer (1), on which a second layer of material (6) is subsequently overlaid in such a way that the marks remain inside the layer-structure of the moving web. The second material layer (6) may comprise a second fiber layer or, for example, a polymer coating. The laser marking could take place, for example, by burning the surface of the fiber layer (1) or by engraving it. Inside the layer structure, the marks (5) are protected, but detectable with a detector to ensure the authenticity of the material. The marked paper or board is suitable for product packages to be protected against product forgeries.
