Method for processing a resin mold and the resin mold thus obtained.

A method of coating a mold containing a resinous surface which comprises the steps of: i) coating the mold with a release agent that is capable of reacting chemically with the resinous surface of the mold ii) reacting the mold resin coated under conditions sufficient to occur a chemical reaction between the resinous surface of the mold and the release agent iii) optionally removing agent unreacted release from the mold, wherein the mold is an article photofabricated obtained by repeating a step of forming a cured layer of photocurable resin composition by selectively irradiating the resin composition with light and wherein the coating layer consisting of reacted release agent has a thickness less than 1 micron.
