ABSTRACT:
A method for recycling an image-deposited recording material having a surface portion which swells in contact with a water-containing liquid composition and bears thereon deposited images containing a thermoplastic or thermofusible image-constituting material is disclosed, which method includes the steps of applying the water-containing liquid composition to the image-deposited surface portion of the recording material to cause the surface portion of the recording material to swell more than the image-constituting material, thereby weakening the adhesion between the deposited images and the recording material; and removing the deposited images from the recording material. The image removal promoting liquid contains a wetting agent which exhibits an equilibrium moisture content of 10% or more under the ambient conditions of 60% relative humidity and 25.degree. C.
