  • Publication number: 20100047531
    Abstract: The present invention relates to a process for the printing or coloring of substrates, wherein substrates to be printed or colored are brought into contact with (A) at least one treated pigment in particulate form which is prepared by a process comprising the following steps: a) dispersion of at least one pigment in particulate form with at least one non-ionic surfactant, b) mixing of the resulting dispersion of pigment in particulate form and non-ionic surfactant with an aqueous medium, c) polymerization of at least one first monomer or copolymerization of a first mixture of comonomers in the presence of a mixture according to b), water-insoluble polymer or copolymer being formed on the surface of the pigment in particulate form, and d) addition of at least one second monomer or a second mixture of comonomers and polymerization or copolymerization, and also with (B) at least one compound which is capable of crosslinking under the action of thermal energy or after the addition of a catalyst.

  • Publication number: 20080217158
    Abstract: Process for recovering cyclododecatriene (CDT) from a solution comprising CDT and high boilers such as deactivated catalyst and polymers, which comprises feeding the solution into a preheater and heating it, subsequently depressurizing it through a downstream pressure maintenance device and feeding the resulting two-phase mixture into a helical tube evaporator and there reducing the CDT content of the liquid phase by partial evaporation and discharging a gaseous product stream having an increased concentration of CDT.

  • Publication number: 20050075453
    Abstract: The present invention relates to a process for preparing dye-comprising aqueous polymer dispersions by free-radical aqueous emulsion polymerization of ethylenically unsaturated monomers in the presence of free-radical initiators, in which at least some of the monomers are employed in the form of an oil-in-water emulsion E1 whose disperse phase comprises at least one oil-soluble dye, wherein the disperse phase of E1 is formed essentially of dye-comprising monomer droplets having a diameter<500 nm. The present invention also relates to perylene dyes of the formula III as set forth in claim 35. The present invention relates in addition to dye-comprising formulations which comprise the dye-comprising polymers of the invention and to pigmented formulations which comprise a polymer of the invention comprising optical brightener.
