Abstract

Thin radiation sensitive coating films contain silicon naphthalocyanines of the formula ##STR1## where Nc is the radical of a naphthalocyanine system which may be substituted by C.sub.1 -C.sub.10 -alyl or C.sub.1 -C.sub.10 -alkoxy, and PA0 R.sup.1 and R.sup.2 are indentical or different and each is independently of the other a radical of the formula ##STR2## where R.sup.3 is branched C.sub.6 -C.sub.20 -alkyl of the formula ##STR3## where n is from 1 to 5 and R.sup.6 and R.sup.7 independently of each other are C.sub.1 -C.sub.16 -alkyl, and R.sup.4 and R.sup.5 are independently of each other C.sub.1 -C.sub.10 -alkyl or the radical OR.sup.3 where R.sup.3 is as defined above, or the radical R.sup.1 may also be C.sub.1 -C.sub.10 -alkyl.
