PHOTO-INDUCED CROSSLINKING OF DOUBLE BOND-CONTAINING POLYMERS BY MEANS OF A PERICYCLIC REACTION

摘要

The present invention relates to a novel method for photoinduced crosslinking of, for example, adhesives or coating compositions.;More particularly, the present invention relates to a novel, irreversible crosslinking mechanism in which it is possible to obtain, through irradiation with visible light, specific photoactive systems via photoenol reactions controlled high-reactivity diene intermediates which crosslink polymers containing double bonds by means of a Diels-Alder reaction.
