Description

Verfahren zur Herstellung von photographischen Gelatinereliefbildern. In dem Patent 358167, Zusatz zum Patent 3o9193, wird ein Verfahren zur Herstellung von photographischen Kolloidreliefs aus Halogensilberkolloidschichten beansprucht, dadurch gekennzeichnet, daß man Pyrogallol mit einem Zusatz von einem Fünftel bis der Hälfte seines Gewichts an kristallisiertem Natriumsulfit oder von der entsprechenden Menge eines anderen Alkalisalzes der schwefligen Säure als Entwickler benutzt.Process for the production of gelatin photographic relief images. In patent 358167, addendum to patent 3o9193, a method of manufacturing claimed by photographic colloid reliefs made of halo-silver colloid layers, characterized in that one pyrogallol with an addition of one fifth to half its weight of crystallized sodium sulfite or the equivalent Amount of another alkali salt of sulphurous acid used as a developer.

Es wurde nun gefunden, daß man mit gleichem Erfolge dem Pyrogallol an Stelle eines Alkalisalzes der schwefligen Säure einen nicht gerbenden - Entwickler, wie z. B. Metol, zusetzen kann. Der Entwickler wird beispielsweise wie folgt zusammengesetzt ioo Teile Wasser, 2 Teile Pyrogalloi, o,2 Teile Metol, 15 Teile Kaliumkarbonat.It has now been found that pyrogallol can be used with equal success instead of an alkali salt of sulphurous acid a non-tanning developer, such as B. Metol, can add. The developer is composed, for example, as follows 100 parts of water, 2 parts of pyrogalloi, 0.2 parts of Metol, 15 parts of potassium carbonate.
