20100015337 | METHOD FOR APPLYING INTERFERENCE PIGMENTS TO A SUBSTRATE - The present invention relates to a method for applying interference pigments to a substrate, comprising the steps: a) provision of a substrate and b) application of a preparation to at least one side of the substrate, where the preparation contains at least one surfactant and at least one interference pigment, the interference pigment having a carrier material and at least one coat applied to the carrier material, and a substrate obtainable by the abovementioned method. | 01-21-2010 |
20090301631 | COATED PAPERS HAVING IMPROVED LABELLING PROPERTIES - A process for producing a coated paper, comprising the steps of: a) providing a base paper, the fraction of long-fibre chemical pulp in the base paper being at least 25% by weight, the base paper leaving an absolute moisture content of ISO 287 of not less than 2.5%, the base paper having a water absorbency to ISO 535 for a test time of 10 s (Cobb | 12-10-2009 |
20090126891 | Method for Coating Cellulose Particles, Coated Cellulose Particles, and Use Thereof In Paper and Board production - The invention relates to a method for coating cellulose particles with a light scattering material, to coated cellulose particles, to the use thereof as a filler and as a coating pigment in paper and board, and further, to methods for producing and for coating paper and board. | 05-21-2009 |
20090114356 | Method of Producing a Fibrous Web - A method of manufacturing a fibrous web comprising a filler. According to the method, the filler is fed into the fibre slush and a fibrous web is formed of the filler-bearing fibre slush, and this web is dried at the paper or cardboard machine. The filler used is a composite material which comprises cellulose or lignocellulose fibrils, onto which light-scattering material particles have been precipitated. According to the present invention, the filler is brought into contact with the dispersant before it is mixed into the fibre slush. With this solution it is possible to significantly improve the light-scattering properties of papers and cardboards, without decreasing the retention of the filler. | 05-07-2009 |
20090057415 | Method for Making Objects which can be Read Electromagnetically - The invention relates to a marking electromagnetically readable from a substrate, a method for producing such a marking, and a memory medium. The marking comprises first areas on a substrate at a distance to each, which comprise at least one electrically conductive material and the electrical conductivity of which is greater than a defined threshold value, and second areas arranged between the first areas, the electrical conductivity of which second areas is less than or equal to the said threshold value. According to the invention, at least two first areas differ substantially from each other in electrical conductivity. With the aid of the invention it is possible to create a marking, the amount of information contained in which is many times that contained in previous electrical markings. | 03-05-2009 |
20090032207 | Process for Producing Mechanical Pulp Suitable for Paper or Cardboard Making - Method for the production of mechanical or chemi-mechanical pulp as raw material for paper or cardboard. According to this method, the pulp is fibrillated and the fibrillated pulp is bleached in alkaline conditions. According to the present invention, the pulp is screened to separate the reject from the accept, at maximum approximately 60% of the total amount of pulp is separated as the reject, the reject is bleached separate from the accept, and, after that, the bleached reject is remixed with the accept. When operating according to the present invention, the strength of the pulp increases and the energy used for refining is reduced, which is seen both in the refining of the reject and in the post-refining of the final mechanical pulp. | 02-05-2009 |
