  Verfahren zur Herstellung von gepresstem, festem Waschblau. 



   Vorliegende Erfindung betrifft eine Ausgestaltung des Verfahrens zur Herstellung von gepresstem, festem Waschblau, welches in bekannter Weise aus Indigokarmin, Ultramarin oder   einem   Anilinfarbstoff besteht, welchen man gegebenenfalls   Kohlensäure   entwickelnde Mittel beimengt, worauf die Masse in Formen gepresst wird. 



   Beim Pressen dieses an sich bekannten Waschblaus ergab sich der Übelstand, dass das fertige Stück schwer aus der Pressform entfernt werden konnte ; einzelne Teile des Waschblaus bröckelten ab und die Stücke erhielten ein unschönes Aussehen. 



   Vorliegende Erfindung besteht nun darin, dass dem obgenannten bekannten Gemenge von Farbstoffen und Kohlensäure entwickelnden Mitteln noch Talk beigemengt wird, wodurch das   Herausnehmen   des Pressgutes aus der Pressform erleichtert und ein   Abbröckeln   verhindert wird. 



   Das Waschblau erhält dadurch einen gewissen Glanz sowie ein gleichmässiges Aussehen, ohne dass die Färbigkeit irgendwie beeinträchtigt wäre. 



   Die besten Resultate erhält man, wenn dem bekannten Gemenge etwa   330/n Talk

  Process for the production of pressed, firm wash blue.



   The present invention relates to an embodiment of the method for the production of pressed, solid wash blue, which in a known manner consists of indigo carmine, ultramarine or an aniline dye, to which carbonic acid-evolving agents are added, whereupon the mass is pressed into molds.



   When pressing this wash blue, which is known per se, the disadvantage arose that the finished piece could hardly be removed from the mold; individual parts of the raccoon crumbled off and the pieces took on an unsightly appearance.



   The present invention now consists in adding talc to the above-mentioned known mixture of dyes and carbonic acid-developing agents, which makes it easier to remove the pressed material from the mold and prevents it from crumbling.



   This gives the wash blue a certain sheen and a uniform appearance without affecting the color in any way.



   The best results are obtained when the known mixture is about 330 / n talc
