    摘要: The object of the invention is coated base paper. According to the invention, it comprises cellulose fibres based pigment-coated paper having 1 to 5 barrier layers. The barrier layer comprises a barrier chemical selected from the group comprising polyvinyl alcohol, acrylate-based barrier latexes and their mixtures. The object of the invention is also a method for the manufacture of coated base paper. In the method, onto a pigment-coated paper based on cellulose fibres 1-5 barrier layers are applicated by using a method not contacting the web.

    摘要: The invention concerns a method and an improved paper machine for making a surface-sized paper web. Pulp is supplied from the headbox (100), wherein additives and/or fillers and/or fines are admixed into the pulp, to the wire section (200), where water is removed from the web (W). From the wire section (200) the web (W) is guided to the press section (300) to press water from the web (W). The web (W) is then dried in the front drying section (400), whereupon the web (W) is surface-coated in the coating section (500) and dried in the post-drying section (600). Finally, the web (W) is reeled by a reeler (800). According to the invention, in the headbox (100) starch and optionally hydrofobic size are admixed or layered into the pulp to be supplied to the wire section (200), so that on at least one side of the web (W) an essentially dense surface is formed, on which in surface-coating a coating paste is spread out, which has a high dry matter content, whereby a bond is achieved in direction z inside the web (W) in between the base paper and the surface-coating layer spread out on the surface. The invention also concerns a surface-sized paper, wherein according to the invention there is a bond in direction z between the surface-coating layer and the base paper.

    摘要: The invention provides an improved method of coating mediumweight and heavyweight papers in a size press by applying a paper coating composition comprising a binder wherein the binder comprises a stable aqueous dispersion comprising a water insoluble component and a water soluble component such that the water insoluble component comprises coalescable polymer particles which have a Tg less than 55 DEG C. and a majority of which have a particle size less than 1 micron; and the water soluble component comprises a water soluble polymer capable of inhibiting coalescence of said polymer particles, or a water soluble polymer and a component capable of inhibiting coalescence of said polymer particles; and wherein said water insoluble component comprises greater that 3% and less than 75% by weight of the binder solids and said water soluble component comprises greater than 25% and less than about 97% of said solids.
