Abstract: A coating mix for the production of coated paper and board is described in form of an aqueous dispersion with a solids content of 50 to 80% consisting of pigments, binders, and additives. The coating mix exhibits thixotropic flow characteristics and is characterized by the usage of special amine-group or amide-group containing polymers, which act as protective colloids for the pigment particles. The coating mix contains preferably between 0.1 to 1 weight percent of a grafted gelatin.

Abstract: Ink-jet-printable material in which a base is coated with a polymer of(a) 50 to 99.5% by weight of at least one basic vinyl heterocycle having a pKa of at least 3.8,(b) 0 to 49.5% by weight of a further copolymerizable monomer, and(c) 0.5 to 10% by weight of a crosslinker.

Abstract: This invention relates generally to the extraction process and provides a novel process and reactor for the continuous extraction of vegetable-fibre material such as wood chips. The process comprises a two stage process, the first stage comprising an extraction process using a methanol:water mixture and the second stage using the same extraction liquid as the first with a greater proportion of water, with sodium hydroxide and anthraquinone. A part of the extraction liquid which is saturated by extraction substances is continually carried away at each stage and after extraction, the mixture is subjected to washing. This process has eliminated the heavy pollution produced by the prior art processes and also has reduced the cost and complexity of the prior art processes.
