Abstract:
The invention relates to a coloured coating composition which can be applied to substrates which are to be coated, for example, base paper or cardboard, for the application in the curtain coating method. The substrate, which can be cardboard or base paper, is coated with one or several free-falling liquid curtains. The binding agent is added to the coating fluid. The binding agent is selected from the group containing styrol-butadiene latex binders, styrol-acrylate-latex binders, styrol-butadiene-acrylnitrile latex binders, styrol-maleic acid anhydride binders and styrol-acrylate-maleic acid anhydride binders. The binding agent has a particle size of
Abstract:
A coating slip composition which can be applied by the curtain coating method to substrates to be coated, for example base paper or cardboard, is described. The substrate, which may be base paper or cardboard, is coated with one or more free-falling liquid curtains, a binder being added to the coating liquid. The binder is selected from the group comprising styrene/butadiene latex binders, styrene/acrylate latex binders, styrene/butadiene/acrylonitrile latex binders, styrene/maleic anhydride binders and styrene/acrylate/maleic anhydride binders, the binder having a particle size of
Abstract:
Tert.-dodecylmercaptan (I), obtained by the acid-catalysed addition of hydrogen sulfide to a mixture containing olefins derived from n-dodecane, 5-methyl-n-undecane, 4-ethyl-n-decane, 5,6-dimethyl-n-decane, 5-ethyl-6-methyl-n-nonane, 4,5-diethyl-n-octane and other hydrocarbons, in amounts of 10-18, 25-40, 25-40, 2-8, 5-12, 1-5 and up to 5 wt% respectively. Independent claims are also included for (1) a method (M1) as described above for the production of (I) (2) a method (M2) for the regulation of mol. wt. in the polymerisation of vinyl monomers by adding (I) as mol. wt. regulator.

Abstract:
Paper, board and cardboard are produced by adding (i) at least one retention aid and (ii) ionic, water-insoluble, uncrosslinked, organic microparticles which have an average particle size of less than 500 nm and a content of polymerized ionic monomers of less than 1% by weight or water-insoluble, uncrosslinked, organic microparticles having an average particle size of less than 500 nm and a content of polymerized ionic monomers of not more than 10% by weight, which are obtainable by polymerizing the monomers in the presence of silica, waterglass, bentonite and/or mixtures thereof, to a paper stock and draining the paper stock over a wire.
