Abstract
A process for imparting releasing property to a mold which comprises applying to the mold a composition comprising: (A) (1) a fluorine-containing urethane compound represented by the formula ##STR1## and/or (2) a fluorine-containing urethane compound represented by the formula ##STR2## and/or (3) a fluorine-containing urethane compound represented by the formula ##STR3## and (B) at least one of members selected from the class consisting of silicone oil, silicone varnish, wax and a highly fluorinated organic compound and the mold release composition used for the process.
