A method of decoloring an image formed on a paper sheet by using an image forming material containing a color former, a developer and a decolorizer, comprising the steps of bringing a solvent into contact with the image forming material for decoloring the image, and removing the residual solvent from the paper sheet.
An erasable image forming material includes a color former, a developer, a binder resin, and a polymer decolorizer having an electron donating group capable of physically or chemically adsorbing the developer. This polymer decolorizer is, e.g., a polymer compound having a sugar skeleton, representatively starch. This image forming material can form sharp images and erase images by heat or a solvent to achieve a good erased state.

The present invention relates to a method of temporarily and firmly fixing two solids to each other and to a composition used in the method, which is a method of temporarily fixing, comprising temporarily fixing the two solids to each other with a liquid crystal compound or a composition comprising the liquid crystal compound. This method is used for a method of temporarily fixing a pad for chemical mechanical polishing, for example, to polish a wafer for a semiconductor device fixed on a surface of a base plate, when one solid is a pad for chemical mechanical polishing of a wafer for a semiconductor device and the other is a base plate to fix the pad.
