Abstract

Sulfonic acid esters of 2,4-bistrichloromethyl-6-(mono- or dihydroxyphenyl)-1,3,5-triazine are disclosed. Also disclosed is a negative-working radiation-sensitive mixture containing such a compound in combination with a compound containing at least two acid-crosslinkable groups, and a water-insoluble polymeric binder which is soluble or at least swellable in aqueous alkaline solutions. The esters are esters of a sulfonic acid or sulfonic acids of the formula R--SO.sub.3 H or R'(--SO.sub.3 H).sub.2 with 2,4-bistrichloromethyl-6-(mono- or dihydroxyphenyl)-1,3,5-triazine of the formulae I and/or II ##STR1## where R is an optionally further substituted (C.sub.1 -C.sub.10)-alkyl, (C.sub.5 -C.sub.10)cycloalkyl, (C.sub.6 -C.sub.10)aryl, (C.sub.6 -C.sub.10)aryl-(C.sub.1 -C.sub.10)alkyl or (C.sub.3 -C.sub.9)heteroaryl radical, R' is an optionally substituted (C.sub.1 -C.sub.10)alkylene, (C.sub.6 -C.sub.10)arylene or (C.sub.3 -C.sub.9)heteroarylene radical, and n may be 1 or 2. The radiation-sensitive mixture according to the invention is remarkable for a high resolution and a high sensitivity over a wide spectral range and can be used to produce a radiation-sensitive recording material suit…
