    • A releasing agent containing:(A) a copolymer which is produced by copolymerization of:(a) a monomer mixture comprising 70 to 40 percent by weight (hereafter represented by "wt. %") stearyl acrylate and/or stearyl methacrylate and 30 to 60 wt. % acrylonitrile; and(b) an ethylenically unsaturated compound being copolymerizable with the monomer mixture and having functional groups reactive with metal alcoholate, the ethylenically unsaturated compound being used in an amount of 0.5 to 30 part by weight (hereafter represented by "wt.part") per 100 wt. part of the monomer mixture; and(B) a metal alcoholate being represented by the following general formula: ##STR1## wherein R is a hydrocarbon group having 1 to 20 carbon atoms or this hydrocarbon group further having oxygen atom, nitrogen atom, sulfur atom or halogen atom, including the case R being identical or not identical with each other in the general formula and R being combined with each other, n is an integer from 1 to 4, m is an integer from zero to 10, and M is a metal element belonging to III, IV and V groups of the periodic table. Another releasing agent containing a copolymer of the above monomer mixture, the above ethylenically unsaturated compound and further at least one monomer being selected from the group consisting of cyclohexyl group-containing ethylenically unsaturated compound in an amount of 2 to 30 wt.part per 100 wt.part of the monomer mixture, and imidazole compound with ethylenically unsaturated group in an amount of 0.5 to 15 wt.part per 100 wt. part of the monomer mixture, wherein the functional groups in the copolymerizable compound monomer are also at least partially cross-linked with the above metal alcoholate.
