Light-sensitive mixture based on diazonium salt polycondensation products, and light-sensitive recording material produced therefrom

摘要

A light-sensitive mixture is described which contains a light- sensitive diazonium salt polycondensation product and, to enhance the light sensitivity, one of the compounds bis(2-hydroxynaphth-1-yl) sulphide, diresorcyl sulphide, diphenyl sulphone, phenothiazine, di-(benzothienyl) sulphone, mercaptobenzothiazole, 2-benzoxazolethiol, 2-hydroxy-3-naphthoic acid N-(3-hydroxyphenyl)-amide, 2-hydroxy-3-naphthoic acid ethanolamide, N,N'-bisacetoacetyl-ethylenediamine, 4-bromo-3,5-resorcylic acid amide, 3,5-resorcylic acid ethanolamide, 2,4-resorcylic acid ethanolamide or N-benzyl-acetoacetamide.
