  • Patent number: 8629207
    Abstract: An aqueous coating formulation for tannin-containing substrates can include a substituted C2-C4 polyalkyleneimine. Reacting a C2-C4 polyalkyleneimine having a weight-average molecular weight of from 500 to 10,000 g/mol with a carboxylic acid derivative can produce the substituted polyalkyleneimine. The carboxylic acid derivative includes at least one C1 to C30 alkyl group or C3 to C30 alkenyl group. Substrates that contain tannin and are coated with this aqueous coating formulation exhibit outstanding resistance with respect to color runs and color strikethrough.

    Abstract: A paper coating slip which comprises metal salt pigments in an amount of at least 40 parts by weight, based on the total amount of pigments, and an aqueous dispersion of water-soluble copolymers is described. The copolymers are obtainable by free radical polymerization of ethylenically unsaturated, anionic monomers with ethylenically unsaturated, nonionic monomers in the presence of polymeric stabilizers for water-in-water polymer dispersions. The paper coating slips have good rheological properties and good water retention behavior in the coating of paper or cardboard.

    Abstract: The invention relates to metal nanoparticles and a process for the preparation thereof, in which a metal salt solution is reduced with a reducing agent in the presence of the derivatized polyethyleneimines or polyvinylamines. Metal salt solutions of two or more different metals can be reduced simultaneously or in succession, metal nanoparticles comprising two or more different metals being obtained. Preferred metals are silver, palladium, and platinum. Suitable reducing agents are, for example, formic acid, formaldehyde, diethanolamine, 5-pentenoic acid and sodium borohydride. Silver can be used in the form of silver oxide and/or silver nitrate, palladium in the form of alkali metal tetrachloropalladate or palladium(II) nitrate and platinum in the form of alkali metal tetrachloroplatinate or tetraamineplatinum(II) nitrate.
