Abstract

PURPOSE: To provide the titled device composed of a drawing part which contains a coloring composition composed of an oxidizing agent comprising a chlorite or a chlorate, and an erasing part containing an acidic substance for erasing the letter, etc. drawn with the drawing part.
CONSTITUTION: The objective device is prepared by combining (A) a coloring composition obtained by adding pref. 100W500pts.wt. of an oxidizing agent composed of a chlorite or a chlorate to 100pts.wt. of a dye (pref. of a color index No. of AB23, AB40, AY3, etc.) (pref. an aqueous solution containing 1W10wt% of the dye and 2W15wt% of the oxidizing agent), and (B) an erasing composition composed of an acidic substance (when used as an aqueous solution, its concentration is pref. 2W20%). When the oxidizing agent in the composition A is chlorite, the aqueous solution is pref. incorporated with 0.5W10% Na2CO3, etc. to improve the storage stability of the composition. The letters, etc. drawn by using the drawing part of the device containing the coloring composition, can be erased by treating with the erasing part containing the erasing composition.
