  • Aqueous dispersions of polymers which comprise a fluorescent dye, process for their production and their use for marking materials
    Patent number: 9006361
    Abstract: Aqueous dispersions of polymers which obtained by free radical suspension polymerization or free radical miniemulsion polymerization of ethylenically unsaturated monomers in an oil-in-water emulsion whose disperse phase comprises at least one fluorescent dye dissolved in at least one ethylenically unsaturated monomer and has an average particle diameter of at least 1 ?m, in the presence of at least one surface-active compound and at least 0.5% by weight, based on the monomers, of at least one hydrophobic, nonpolymerizable, organic compound, of a hydrophobic polymer of at least one C2- to C˜-olefin having a molar mass Mw of up to 10000, of a siloxane having a molar mass Mw of up to 5000 and/or polystyrene having a molar mass Mw of up to 10000, and of the powders obtainable from these polymer dispersions in each case by drying and comprising at least one fluorescent dye for marking of materials.

  • PIGMENT-FREE, AQUEOUS POLYMER DISPERSIONS MARKED WITH FLUORESCENT DYES, PROCESS FOR THEIR PREPARATION AND THEIR USE
    Publication number: 20100240772
    Abstract: Pigment-free, aqueous polymer dispersion marked with fluorescent dyes, having a viscosity of from 500 to 900 mPa·s, determined with the aid of the Brookfield method (spindle 3, 23° C.), and comprising, based in each case on the solids of the polymer dispersion, (A) from 1 to 99% by weight of at least one type of water-soluble and/or water-dispersible polymer, (B) from 1 to 20% by weight of at least one type of water-dispersible polymer particles which comprise at least one fluorescent dye and (C) from 0.001 to 3% by weight of at least one thickener; process for its preparation and its use.
