Disclosed is a process for developing a two-component diazocopying material, comprising the steps of providing a film of an ammonia-steam mixture or of an aqueous ammonia solution, respectively, flowing uniformly into the interior of an evaporation zone and being uniformly heated at the same time to release a developing gas in the evaporation zone; providing a liquid developing solution in a sump zone; evaporating a portion of the developing solution to produce a developing gas in the evaporation zone located above the sump zone, passing the diazocopying material through a developing zone; introducing the developing gas from the evaporation zone into the developing zone and contacting the diazocopying material with the developing gas in the developing zone; maintaining the temperature in the developing zone at a level higher than the temperature at which the developing gas enters from the evaporation zone; and maintaining the temperature in the sump zone at a level higher than the temperature in the evaporation zone but not exceeding the temperature in the developing zone. Also disclosed is an apparatus for carrying out this process.

A process for developing a two-component diazocopying material, comprising the steps of: providing a film of a mixture of ammonia and water flowing uniformly into the interior of an evaporation zone and being uniformly heated at the same time to release a developing gas in the evaporation zone; providing a liquid developing solution in a sump zone; evaporating a portion of said developing solution to produce a developing gas in said evaporation zone located above said sump zone; passing the diazocopying material through a developing zone; introducing said developing gas from said evaporation zone into said developing zone and contacting said diazocopying material with said developing gas in said developing zone; maintaining the temperature in said developing zone at a level higher than the temperature at which the developing gas enters from said evaporation zone; and maintaining the temperature in said sump zone at a constant value without influencing the temperatures in the developing zone and in the evaporation zone; said constant value being at a level higher than the temperature in the evaporation zone but not exceeding the temperature in said developing zone.
