Abstract
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.
Claims19
A composition comprising a mixture of;
- a. a triallyl cyanurate prepolymer and/or a precopolymer of triallyl cyanurate with a compound containing a radical selected from the group consisting of allyloxy, allylester and mixtures thereof;
- and
- b. a compound containing at least one N-maleimide group wherein the C.dbd.C double bond of the N-maleimide group is bonded to two radicals selected from the group consisting of hydrogens, hydrogen and chlorine, and hydrogen and methyl.
