PCT No. PCT/DE97/00165 Sec. 371 Date Jul. 21, 1998 Sec. 102(e) Date Jul. 21, 1998 PCT Filed Jan. 23, 1997 PCT Pub. No. WO97/27063 PCT Pub. Date Jul. 31, 1997The description relates to a process for producing a multi-layer correcting and/or marking material. In said process, a film is applied to a substrate which can be released therefrom and in particular contains a dye and/or pigment. A further layer containing an adhesive is then applied over the film thus obtained. The removable film is applied in the form of an aqueous suspension containing a brittle and a film-forming binder. The process makes it possible to dispense with organic solvents. A correcting or marking agent thus produced exhibits good tear-off properties.
