ABSTRACT:
On an apparatus for developing latent images of diazotype prints with a developer liquid containing an organic amine or amines as the developing agent, the tendency of the diazotype paper to curl and wind round the applicator roller is effectively precluded by the addition of a very small amount of a fluorocarbon non-ionic surface active agent. The amount of the agent is preferably in the range from 0.01 to 1% of the total weight of the developer composition.
