Abstract
Improvements introduced in the preparation of perfected, single-component diazotyping materials, containing a p-aminobenzene diazo compound derived from a tertiary aromatic amine having only one aryl radical directly attached to the tertiary nitrogen atom, which radical carries the groups diazo in position for the tertiary amino group, and in one of the positions ortho to the tertiary amino group carries an etherified hydroxide group, while the benzene nucleus carrying the diazo group may contain, in addition to the diazo group, the group etherified hydroxyl, and the tertiary amino group, another substituent in position para to the etherified hydroxyl group, the hydroxyl group being etherified with a phenyl radical which may or may not be substituted, consistent improvements in that the materials for diazotypia contain a diazo compound according to the formula general: ** (See formula) ** where X is an anion, Y represents a halogen atom Ac an acyl radical, R an alkyl or radical (see formula) R 'a hydrogen atom or methyl group, Z a halogen atom, and n is 0,1,2 or 3.
