Patent-Ansprüche: 45Patent Claims: 451. Verfahren zur Herstellung photographischer Abdrücke auf Pigmentpapier, gekennzeichnet
durch die Anwendung eines Pigmentpapieres, bei dem als Pigment ein die trockne Kolloidschicht rauh machendes
Pulver benutzt wird, welches nach dem in üblicher Weise erfolgten Sensibilisieren, Kopieren,
Entwickeln und Trocknen ein Bild liefert, in dem alle belichteten Stellen rauh und alle nicht belichteten Stellen glatt
sind, und das durch Überreiben mit einem trocknen Farbpulver fertiggestellt wird.1. Process for the production of photographic impressions on pigment paper, characterized
through the use of a pigment paper, in which the pigment is a roughening of the dry colloid layer
Powder is used, which after sensitizing, copying,
Developing and drying provides an image in which all exposed areas are rough and all unexposed areas are smooth
and that is finished by rubbing it over with a dry paint powder.2. Papier zur Ausführung des Verfahrens nach Anspruch 1, bei welchem die
das rauh machende Pulver enthaltende Schicht mit einem in Wasser unlöslichen
Farbkörper angefärbt ist, dessen Färbung durch eine das rauhe Bild nicht schädigende
Reaktion zu beseitigen ist.2. Paper for carrying out the method according to claim 1, wherein the
the layer containing the roughening powder with a water-insoluble one
Color body is colored, the coloring of which does not damage the rough image
Reaction is to be eliminated.
Production of multicolored paintings or drawings by painting or drawing each individual color on a separate transparent layer without the use of photographic aids and applying these layers, painted in individual colors, to the production of color printing plates
