The invention relates to cyclobutanedicarboxisoimides of the formula I ##STR1## wherein one of X and Y is oxygen and the other is ##STR2## each of R.sub.1 and R.sub.6 independently is methyl or ethyl, each of R.sub.2 and R.sub.3 independently is hydrogen, fluorine or methyl, or R.sub.2 is aceto hydrogen or methyl, while R.sub.3 and R.sub.4 together can also form an additional valency in the 4-membered cycloaliphatic ring. These compounds are suitable for controlling a variety of phytopathogenic fungi. They can be obtained by cyclizing the corresponding cyclobutanedicarboxylic acid monoamides in the temperature range from about -20.degree. to +100.degree. C., in the presence of dehydrating agents such as acetic anhydride or N,N'-dicyclohexylcarbodiimide.

Novel tricyclic imidyl derivatives, for example those of the formula ##STR1## [n=1 or 2, Y=a bridge member and X=a functional group] are described. The novel tricyclic imidyl derivatives are suitable for the preparation of photocrosslinkable polymers by incorporation into existing polymer chains or by building up the polymer chain from tricyclic imidyl derivatives, according to the definition, with suitable functional groups X by polymerization or polycondensation. The photocrosslinkable polymers obtained by this means can be used, for example, to produce printing plates for the offset printing process and especially as photoresists.
