Such derivatized carbon may be used in an electrode of an electrochemical sensor.

Abstract: To provide an information writable film that is chemical and abrasion resistance, and is suitable for high contrast white laser marking. The information writable film comprises a writable film layer 110 and a reading assistance layer 120. The writable film layer 110 is formed into a film shape by thinly stretching a material, which material is a mixture of a color former composition for coloring white when receiving the particular wavelength laser beam by changing its physical and chemical characteristic and a transparent plastic composition. The reading assistance layer 120 is provided enhancing the contrast ratio. The writable film layer 110 is provided with laser coloring properties and chemical and abrasion resistance. During writing, an identification code is written by laser by coloring the color former in the writable film layer 110. During reading, the contrast ratio is enhanced by superimposing the color of the reading assistance layer 120.
