溶液を作成した。To this solution, 0.5' of a 1% dimethylformamide solution of a spectral sensitizer having a maximum absorption wavelength of 73 m was added.
 Mixed thoroughly. This was coated on the same tracing paper as in Example 1 and dried to obtain an electrophotographic paper with a solid content coating amount of 5 g/mt. This sample was subjected to image exposure of 50 lux x 0.9 sha through a transparent positive original after being charged with a negative electrostatic charge, and then a liquid phenomenon was performed to obtain a fog-free positive copy image. In order to further copy this onto diazo photosensitive paper as a second original image, a positive copying device Copy Flex Model 110 (the light source is a high-pressure mercury lamp) manufactured and sold by Bruning Co., Ltd. of the United States was used by a wet method to copy it onto diazo photosensitive paper. When copying was performed on diazo photosensitive paper YP-B manufactured and sold by the company using the highest speed dial of the above-mentioned device, beautiful copies with very little fog were obtained. Example 6 Organic optical semiconductors (2 types) in the present invention shown in Table 3 below
 and 1 g each of organic optical semiconductors for comparison (2 types) were mixed with 0.0 g of polystyrene resin. The mixture and 0.5 g of polycarbonate resin were dissolved in monochlorobenzene to create a solution with a total volume of log of each.

載した。The coloring solution thus prepared was coated onto electrically conductive coated paper (base paper weight 8 female/minor) using a test coater and dried so that the coating amount after drying was about/min. The surfaces of these coated samples were charged with a negative electrostatic charge by corona discharge in a microwave oven, and then exposed to near-infrared light (sample surface illuminance: 5 lux), and the amount of exposure to half the potential of each sample was measured. Apart from this, we also created photosensitive liquids that would not be left exposed to sunlight.
 A photosensitive coloring solution containing exactly the same amount of the sensitizing dye and chemical sensitizer in this example was coated on coated paper and dried to serve as a reference sample, and the potential half-reduction exposure was measured in the same manner, and the results are shown in Table 4. Described.

光量が低下していることがわかる。From the results in Tables 3 and 4 above, the organic optical semiconductor of the present invention shows almost no change in the potential half-exposure amount even when irradiated with sunlight, whereas sample No. 2 and no. It can be seen that the comparative organic optical semiconductor of No. 4 has a considerably reduced potential half-exposure due to sunlight irradiation.
