Abstract

Procédé de développement à sec d'un matériau de diazotypie dans lequel le dos du matériau est maintenu à température constante pendant toute la durée du contact avec les vapeurs ammoniacales de développement L'invention concerne aussi un dispositif de mise en oeuvre de ce procédé. Un cylindre chauffé au contact duquel se trouve le matériau de diazotypie entraîne celui-ci à travers une chambre de développement, les vapeurs ammoniacales résiduelles étant absorbées par aspiration à la sortie de ladite chambre. Application : développement sec de matériaux diazotypes.Method for the dry development of a diazotype material in which the back of the material is maintained at constant temperature throughout the duration of contact with the ammoniacal development vapors. The invention also relates to a device for implementing this method. A heated cylinder in contact with which the diazotypic material is located drives the latter through a development chamber, the residual ammoniacal vapors being absorbed by suction at the outlet of said chamber. Application: dry development of diazotype materials.
