摘要:
A dye compound has the following general formula (1). In the general formula (1), A1 denotes N or CR2. When A1 denotes N, R1 denotes an amino group. When A1 denotes CR2, R1 and R2 form an aromatic ring that has an anionic group. R3 denotes an alkyl group, an aryl group, or an aralkyl group. Cy denotes a substituted or unsubstituted aromatic ring.
摘要:
A dye compound represented by the following formula has at least one anionic group: wherein R1 and R2 independently represent an amino or hydroxyl group, A1 represents nitrogen or CR4, R4 and R3 form a first aromatic ring, R3 represents a substituent with a negative Hammett's substituent constant when A1 represents nitrogen, and Cy represents a second aromatic ring.

摘要:
A method of erasing an image for erasing an image formed by applying ink containing a dye to a recording medium. The image is exposed to an oxidizing gas generated by dielectric barrier discharge. An apparatus for performing the method and a method of recycling the recording medium are also provided.
摘要:
The invention provides a method for easily and promptly erasing an image (including a character) formed on a printed article, and an apparatus employing such method. A printed article bearing an image formed on a surface including an inorganic pigment is exposed to a reactive gas, generated by creeping discharge or corona discharge induced by a voltage application between a pair of opposed electrodes, whereby the image is erased.

The invention provides a method for easily and promptly erasing an image (including a character) formed on a printed article with a low cost, and an apparatus employing such method. A printed article bearing an image formed on a surface including an inorganic pigment is exposed to a reactive gas generated by creeping discharge or corona discharge induced by a voltage applied between a pair of opposed electrodes, whereby the image is erased.
