Abstract: Silicon naphthalocyanines of the formula … … in which… Nc denotes the radical of a naphthalocyanine system which is optionally substitued by C1-C10-alkyl or C1-C10-alkoxy, and… R and R independently of one another denote a radical of the formula … … in which R stands for branched C6-C20-alkyl of the formula … … in which n has the meaning 1 to 5 and R and R independently of one another have the meaning C1-C16-alkyl, and R and R independently of one another stand for C1-C10-alkyl or the radical OR , in which R has the abovementioned meaning, or the radical R also denotes C1-C10-alkyl, and thin radiation-sensitive coating films containing these silicon naphthalocyanines.
