Patent ID: 8008366

Claim:
A process for producing a cured coating, the process comprising: a step of forming on an organic polymer substrate a layer of a curable composition comprising at least one compound represented by Formula (I); and a step of curing the layer of the curable composition by irradiating with an electron beam, in Formula (I), Q 1 denotes a cyano group or a —COX 2 group, X 1 denotes a hydrogen atom, organic residue, or polymer chain bonded to carbon atom C A via a heteroatom, or a halogen atom, X 2 denotes a hydrogen atom, organic residue, or polymer chain bonded to the carbonyl group via a heteroatom, or a halogen atom, R a and R b independently denote a hydrogen atom, a halogen atom, a cyano group, or an organic residue, and X 1 and X 2 , R a and R b , and X 1 and R a or R b may be bonded to each other to form a cyclic structure, wherein the curable composition does not comprise a polymerization initiator, the acceleration voltage for irradiation with the electron beam is 5 to 150 kV, and the irradiance of the electron beam is 1 to 200 kGy.
