PURPOSE:To enable the fluorescent surface of a color cathode-ray tube to be made through an extremely simple process by adding as a photosensitive component an aromatic diazonium compound represented by a given general formula. CONSTITUTION:The fluorescent surface of a color cathode-ray tube contains an aromatic diazonium compound represented by formula-I: R1 and R2 represent a straight chain alkyl group; R3 and R4 represent H, CH3 or OCH3; A represents C.l1/2ZnCl2, BF4 or HSO4. An N,N-dimethylamino compound is used in preparing the fluorescent surface, since an N,N-diethyl aminocompound or the like is hardly ?crystallized. For the purpose of making the photosensitive compound to be much more easily applied and of making a layer of the photosensitive compound thin, the ratios of the organic high molecular compound and a surfactant to the aromatic diazonium compound are preferred to be, for example, 0.5-500wt% and 0.01- 1wt%, respectively. Consequently, the fluorescent surface can be formed through an extremely simple process. |
