摘要： Particles of a polysaccharide derivative, having at least one substituent with conjugated unsaturated bonds and exhibiting an index of refraction in excess of 1.50 and a method for the production thereof. In the method, the raw-material is suspended in an organic solvent to form a suspension, which is contacted with an organic reactant comprising a residue with conjugated unsaturated bonds; the raw-material and the organic reactant are reacted to form a derivative exhibiting ester or ether bond between the raw-material and the residue with conjugated unsaturated bonds; the polysaccharide derivative is dissolved in a solvent to form a solution; and the solution is contacted with a non-solvent to precipitate particles of the polysaccharide derivative. The invention provides lightweight, optically improved organic pigments and fillers based on renewable resources and which are recyclable by combustion or composting.

摘要： The invention relates to a method for dissolving cellulose e.g. for the production of regenerated cellulose products such as films, fibres, particles and the like. In said method, the cellulose material is dissolved using an enzymatic treatment, followed by a base treatment. The invention is also directed to a method for producing cellulose particles wherein cellulose dissolved as described above is sprayed or mixed into a regenerating solution for precipitating cellulose particles. Moreover, the invention relates to the use of said cellulose particles produced with this method as a filler and/or coating pigment of paper and board. The invention is also directed to methods for producing and coating paper and board.
