PURPOSE:To obtain a transferring paper for an electrophotography capable of obtaining a copy having good contrast without whitening, by incorporating or coating bis-aminostilbenesulfonic acid type fluorescent dye into a transferring paper. CONSTITUTION:A fluorescent dye expressed by formula (X denotes Cl, H and lower alkyl or CH3O, Y denotes H or lower alkyl, X and Y may be the same or different, M denotes cation H, alkali metal or alkaline earth metal) is mixed with pulp to prepare paper incorporated with said dye. Said paper or paper for which the dye is applied thereon is used for a transferring paper for electrophotography. By this way, a copy having high whiteness of the transferred paper and good contrast is obtained and moreover whitening at the time of high himidity is not generated. |
