Dye preparation |
| abstract |
A dye preparation consists of a water-soluble acid dye and a water-insoluble basic carrier for the acid dye. The carrier consists of crosslinked polymer particles with an average particle diameter of less than 1 μm and a quaternary ammonium or phosphonium group content of at least 2 meq / g. The dye is drawn onto the polymer particles in an ion exchange reaction. The polymer treated in this way can easily be isolated, stored and redispersed to form dye-polymer latices and is suitable for the production of colored layers, e.g. in photographic recording materials. |
