摘要： PURPOSE:To provide photographic spectral sensitizing dye high in sensitivity and small in residual color due to dye stains and fogging. CONSTITUTION:The photographic spectral sensitizing dye is characterized by being represented by the formula in which each of Z and Z is an atomic group necessary to form a benzoxazole, bezothazole, benzoselenazole, or benzimidazole ring; each of R -R and R is, independently, an optionally substituted alkyl or alkenyl; each of R , R , R , andR is, independently, H, an optionally substituted alkyl or alkenyl or aryl; each of L1-L7 is, independently, an optionally substituted methine; each of m and n is, independently, 0 or 1, but not 0 at the same time; and X is a counter ion.

摘要： PURPOSE:To obtain superior antihalation effect by incorporating a specified dye. CONSTITUTION:The photographic dye to be added is represented by formula I in which R1 is alkyl, alkoxy, or the like; R2 is sulfoakyl, sulfoaryl, or the like; R3 is alkyl, aryl, or the like; M is H, an alkali metal or ammonium salt, or the like; and each of m and n is 1 or 2. The silver halide photographic sensitive material colored by this dye has a wide absorption band in the objective wavelength region, but almost no needless side absorption in the other wavelength region, and superior irradiation prevention and antihalation effects and filter effect can be fully exhibited by using a small amount of the dye.

摘要： PROBLEM TO BE SOLVED: To restrain occurrence of black spots and increase of a min. density at the time of development processing of a silver halide photographic sensitive material without affecting photographic characteristics by developing it in the presence of a specified compound. SOLUTION: This photosensitive material is developed in the presence of the compound represented by the formula in which each of R1 and R2 is an H atom or an alkyl group or the like but each does not become and H atom at the same time and each may combine with each other to form a ring and at least one of them has a hydroxy or carboxy group or the like; M is an H or alkali metal atom or an ammonium group; R3 is an H atom or an alkenyl group or the like; and R4 is an alkenyl or alkynyl group or the like. The compound of the formula is added into the photosensitive material or a developing solution, but it is preferred to add it into the developing solution in order to reduce effects to be exerted to the photographic characteristics and not to deteriorate dot quality and to restrain occurrence of black spots.
