Abstract
A method of obtaining a material equipped with sensitive layers to make copies by diazotypy, which can be used as originals, essentially characterized by the fact that these layers are contained as photosensitive compounds, diazotized combinations that respond to the formula *** see Image 01 in which R1 and R2 represent alcohol groups with 1 to 4 carbon atoms and which also contain aqueous soluble alkyl phenols as coupling compound.
