titleOfInvention | Heat stable monoazo magenta pigment compositions |
abstract | Disclosed are blue shade red to magenta monoazo pigments which are obtained by diazotization of 5-alkoxy-2-aminobenzenesulfonic acids, coupling of the diazonium compound with a hydoxynaphthalenesulfonic acid and subsequent laking of the coupling product with a divalent metal salt. The pigments are characterized by the formula:wherein R is a lower alkyl, e.g. a methyl or ethyl group, or a hydroxycarbyl group, R1 is hydrogen, chloro, a lower alkyl group such as methyl or ethyl, or a lower alkoxy group such as a methoxy or an ethoxy group, and M is Ca, Sr, Ba, Mn, Mg or Zn. The new pigments have a magenta color, excellent heat stability, bleed fastness and very high color strength. These pigments are suitable for the pigmenting of plastics, inks and coatings, among other materials. |
