Abstract

A resin crosslinkable by electron or photon irradiation (gamma rays, X-rays or ultraviolet rays), which is (after crosslinking) very stable under the action of ambient light and heat. It contains a substance the chemical formula of which comprises a thietane ring: ##STR1## notably a compound of the methacrylic ester polymer type wherein the monomer has the general formula: ##STR2## wherein n may be zero or equal to an integer from 1 to 10. The process for using such a resin consists of dissolving it in a solvent, then applying a thin layer of the solution on the object to be coated and finally treating the coating by irradiation.
