Disersu00f5e aqueous polymers, process for the preparation of provisions aqueous polymers, polymer particles, the use of aqueous dispersions of polymers, binding agent.Pulp for paper coating, and agent of the bilge of the paper.Aqueous dispersions of polymers that are obtainable by free radical polymerization in suspension of monomers etilicamnete unsaturated oil - in - water emulsion.The dispersed phase comprises at least one fluorescnte dye dissolved in at least one etienicamente unsaturated monomer and has an average particle diameter of at least 1 A,In the presence of at least one surface active compound and at least 0.5% by weight, based on the monomers, at least one organic compound non polymerisable hydrophobic.A hydrophobic polymer, a hydrophobic polymer formed from at least a C2 - C8 olefin, having a molar mass MW to 10.000, a siloxane having a molar mass MW up to 5000 and / or polystyrene having a molar mass MW to 10.000, processes for the preparation of such dispersions and the use of aqueous dispersions of polymers.Which are obtainable by free radical polymerization in suspension or by free radical polymerization in miniemulsu00e3o of monu00f4metro etilicamnete unsaturated oil - in - water emulsionThe dispersed phase comprises at least one fluorescent dye dissolved in a monomer by emnos etilicamente unsaturated and has a diameter of particle medium of at least 100 nm.In the presence of at least one surface active compound and at least 0.5% by weight, based on the monomers, at least one organic compound non polymerisable hydrophobic.A hydrophobic polymer formed from at least a C2 - C8 olefin having a molar mass MW to 10.000, a siloxane having a molar mass MW up to 5000 and / or polystyrene having a molar mass MW to 10.000, and dust, which comprises at least one fluorescent dye and is obtainable from these dispersions of polymer, through drying, in each case, for marking materials.
