HIGH CONTRAST DEVELOPING METHOD FOR PHOTOGRAPHIC IMAGE |
摘要 |
PURPOSE:To obtain excellent dot image quality with a stable developing soln. by using a processing soln. from which an amino compd. harmful to the human body is removed by developing a silver halide photographic sensitive material applied with a latent image on the surface in the presence of the compd. expressed by the specific formula. CONSTITUTION:The ultra-high contrast image is formed by using the hydrazine compd. expressed by the formula in the stage of forming the photographic image using the silver halide photographic sensitive material. The silver halide photographic sensitive material applied with the latent image on the surface is developed in the presence of the compd. expressed by the formula. In the formula, R1 denotes an aryl group and R2 denotes an aryl group or alkyl group. The excellent dot image quality is expressed with the stable developing soln. by using the processing soln. from which the amino compd. harmful for the human body is removed. |
