PURPOSE: An absorptive release film is provided to minimize physical property change of a release layer by absorbing water into the opposite side of the release layer. CONSTITUTION: An absorptive release film comprises: a polyester substrate film(1); a silica gel coating layer(3) in which a metal compound is contained in one side of the substrate film; and a release layer(2) which is formed in the other side of the base film. The silica gel coating layer and release layer are coated in a line. The release layer is coated with silicon a water-dispersible release coating composition. The silicon water-dispersible release coating composition includes organopolysiloxane, organopolysiloxaneresin, organo hydrogen polysiloxane, and platinum chelate catalyst.
