DEFINITION

Classification: 430/146

Diazo-type process, i.e., producing dye image by reacting the diazo or the imaged reaction product of the diazo:

(under subclass 141) Processes wherein a dye image is formed by the reaction of the diazo compound or the imaged reaction product of the diazo compound. Usually an azo or azomethioine dye image is formed.
