摘要： PURPOSE:To ensure that excellent heat resistance and moisture resistance are obtained by forming a specific condensed bond using a pyrazolothiadiazine derivative. CONSTITUTION:Pyrazolothiadiazine coloring matter has a condensed ring as expressed by the formula. In the formula, R1, R2 are hydrogen atom and an alkyl group respectively and can form a 5-member or 6-member ring. R3 to R6 are hydrogen atom, halogen atom, an alkyl group, a substitution alkyl group, an alkoxy group or a substitution group, and R1 and R4, R2 and R6 can form a 5-member or 6-member ring by bonding each other. R7 is hydrogen atom or a substitution group; Z is a non-metal atom group required for the formation of a heterocyclic 5 to 7-member ring and a non-metal atom group required for the formation of a benzene ring or a naphthalene ring; n is 1 or 2. Thus it is ensured to obtain excellent heat resistance and moisture resistance.

摘要： PURPOSE:To improve the fastness of magenta dye images to light, heat and humidity and to improve the generation of Y-stains in uncolored parts by incorporating specific magenta couplers and specific dye image stabilizers into the above photosensitive material. CONSTITUTION:At least one of the magenta couplers expressed by formula I and at least one of the compds. expressed by formula II are incorporated into this photosensitive material. In the formula I, Z denotes the nonmetal atom group necessary for forming a nitrogenous heterocycle; X denotes a hydrogen atom or the substituent which can be eliminated by reaction with the oxidant of a color developing agent; R denotes a hydrogen atom or substituent. In the formula II, R and R respectively denote a hydrogen atom, alkyl group, cycloalkyl group, etc.; R denotes an alkyl group, cycloalkyl group, etc.; R denotes a substituent; l denotes 0 or 1 to 4 integer; J denotes -C(=O)-O-, -S(=O)2-, -C(=O)-S-, etc.; R denotes an alkyl group or aryl group. The color photographic sensitive material which has excellent color reproducibility and is greatly improved in the fastness of the magenta dye image to light is obtd. in this way.

摘要： PURPOSE:To form a cyan dye image not causing a change of the hue under heat, moisture and light by using a specified compd. as a coupler. CONSTITUTION:A compd. represented by formula I is used as a photographic coupler. In the formula I, each of R1, R2 and Y is H or a substituent, X is a group which is released by a reaction with the oxidized body of a color developing agent, n is an integer of 0-4 and in the case of n >= 2, plural R2's may be different from each other. The coupler represented by the formula I is a triazolopyridazine deriv. and a typical compd. is shown by tape I. A cyan dye image having fastness to heat, moisture and light and not causing a change of the hue under heat, moisture and light can be formed.

摘要： PURPOSE:To stabilize a formed cyan or magenta dyestuff image to heat, moisture and light by using a specified coupler. CONSTITUTION:A photographic coupler represented by one of formulae I-IV is used. In the formulae I-IV, Z is a group of nonmetallic atoms required to form a 5- to 7-membered hetero ring, a benzene or naphthalene ring, Z' is a group of nonmetallic atoms required to form a 5- to 7-membered hetero ring, X is H or a group which can be released by a reaction with the oxidized product of a color developing agent and each of R and Y is H or a substituent. A magenta or cyan dyestuff image not causing a hue change under heat, moisture and light is formed.
