PHOTOSENSITIVE SILVER HALIDE MATERIAL FOR OBTAINING HALF-TONE BLACK-AND-WHITE IMAGES AND METHOD FOR HALF- TONE HIGH-CONTRAST REPRODUCTION |
摘要 |
<p>Photosensitive Silver Halide Material For Obtaining Half-Tone Black-And-White Images And Method For Half-Tone High-Contrast Reproduction A photosensitive silver halide material for obtaining black and white half-tone dot or line images comprises a fine grain and high-chloride silver halide emulsion reactively associated with an aqueous latex of a hydrophobic vinyl addition polymer in combination with a stabilizer selected from the group consisting of 4-hydroxy-1,3,3a,7-tetrazaindenes, benzotriazoles and benzimidazoles. The silver halide emulsion has an average grain size lower than or equal to 0.20 micron with at least 60% of its molar halide content consisting of chloride ions. The material allows high-contrast and high resolving power images to be obtained. The material has a good developability in photographic processing and this reduces the development times and increases productivity.</p> |
