Ultraviolet dosimeter film

Abstract

An ultraviolet-sensitive dosimeter material comprises at least one diazonium compound featuring absorption in the ultraviolet wavelength range, and a binder. The diazonium compound is preferably formed by a diazonium salt of the general formula ##STR1## in which R.sub.1, R.sub.2, R.sub.3 and X.sup.- are selected from the following groups: R.sub.1 : H, halogen, alkyl with C.sub.1 -C.sub.5, alkoxy with C.sub.1 -C.sub.5, aryloxy, R.sub.2 : H, halogen, alkyl with C.sub.1 -C.sub.5, alkoxy with C.sub.1 -C.sub.5, aryloxy, NR'R" (R', R" same or differing alkyl compounds or heterocyclic armines, or COOR.sub.4 (R.sub.4 alkyl with C.sub.1 -C.sub.5), and R.sub.3 : H, alkoxy with C.sub.1 -C.sub.5, and X.sup.- : diazo process anions, or perfluorinated aliphatic or aromatic anions.
