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.
Присытствыющий вымысел относит к процессу для подготовлять красить-sosto4 из водяные рассеивания полимера свободно-radikal6no1 водяной полимерностью эмульсии этеново unsaturated мономеров in the presence of свободно-radikal6nye инициаторы, в которых по крайней мере некоторые из мономеров использованы in the form of oil-in-water эмульсия E1 которой участок disperse состоит из по крайней мере одной oil-soluble краски, при котором участок disperse E1 сформирован необходимо красить-sosto4 из капелек мономера имея диаметр
