The invention provides mixtures based on resins containing allyl groups and being solid at room temperature, useful for the preparation of thermally stable, photo-crosslinkable layers and foils. According to the invention, such mixtures comprise triallylcyanurate prepolymers and/or triallylcyanurate precopolymers with compounds containing allyloxy and/or allylester groups, and compounds with at least one N-maleimide group, wherein the C.dbd.C double bond of the N-maleimide groups are bonded to hydrogen, hydrogen and chlorine or hydrogen and methyl radicals. Preferably, the N-maleimide C.dbd.C bonds carry hydrogen.
