Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a silver halide photographic material and a developing method.

[0002]

2. Description of the Related Art Conventionally, cellulose triacetate (TAC) has been mainly used as a 135 light-sensitive material support. However, TAC has extremely low tear strength, and if a film has a slight defect,
There has been a problem that a failure such as disconnection during development processing from the starting point is likely to occur. To solve this,
A silver halide photographic light-sensitive material using a polyester support (hereinafter sometimes abbreviated as a light-sensitive material) is disclosed in JP-A-6-0351.
No. 18 has proposed this. However, when a brownie 135 system light-sensitive material was prepared using this light-sensitive material and subjected to a development process at a developing laboratory (lab), a problem of easy meandering occurred. This meandering remarkably occurred in the light-sensitive material using the slit at the end when forming the polyester support. Further, as compared with the new photographic system (APS) light-sensitive material, it was significantly generated in a wide light-sensitive material such as 135 light-sensitive material or brownie light-sensitive material.

[0003] One of the causes of such meandering is presumed to be due to the bowing phenomenon at the time of film formation. As a technique for improving this, Japanese Patent No. 2917443 discloses a
A method of cooling to a temperature equal to or lower than the glass transition temperature (Tg) after the transverse stretching zone and before the heat setting zone (cooling method before heat setting) has been proposed. Although the support formed by this method has improved bowing, there is a problem that the mechanical strength is likely to be increased. Due to this increase in mechanical strength, the flexural modulus
(The waist of the support) becomes stronger, and conversely, it tends to meander.
That is, it is easy to meander overcoming the transport tension. Therefore,
In order to suppress the meandering generated in the development processing, it is necessary to reduce the bowing during the polyester film formation and at the same time not to increase the flexural modulus of the polyester support. Further, polyester is characterized in that it has a higher mechanical strength than TAC and is hard to be cut during the development process. However, when the mechanical strength is further increased, it becomes more difficult to cut with a cutter blade of laboratory equipment, and improvement has been desired. Such a problem was particularly remarkable in the 135 photosensitive material having many cutting steps.

[0004]

Another object of the present invention is to provide a method for developing a silver halide photographic light-sensitive material which is excellent in transport stability of a developing machine and cutting performance of laboratory equipment.

A support made of a polyester having an intrinsic viscosity [η] of 0.25 to 0.5 dl / g measured at 20 ° C. in a phenol / 1,1,2,2-tetrachloroethane mixed solvent (weight ratio: 60/40).

[0006]

Embodiments of the present invention will be described below in detail. In the silver halide photographic light-sensitive material of the present invention, the intrinsic viscosity measured at 20 ° C. in a phenol / 1,1,2,2-tetrachloroethane mixed solvent (weight ratio: 60/40) is 0.25 to 0.5. 5 dl / g, more preferably 0.30 to 0.48 dl / g, further preferably 0.3
Used for a support consisting of 5 to 0.46 dl / g polyester. Heretofore, polyesters having an intrinsic viscosity in the above range have not been used as a support for silver halide photographic materials. Further, the polyester has a molecular weight distribution (Mw).
/ Mn) is preferably from 2.0 to 2.6, more preferably from 2.1 to 2.5, and still more preferably from 2.1 to 2.4. Further, the polyester preferably has a content of diethylene glycol (DEG) present as an impurity of 0.5 to 5%, more preferably 0.1 to 5%.
It is 5-4%, more preferably 1-3%.

[0007] By using a polyester having an intrinsic viscosity in the above range as a support, bowing is unlikely to occur without using a cooling method before heat setting during film formation, and a slit at an end of the formed polyester film is supported. A silver halide photographic light-sensitive material which does not easily meander during development processing even when used for a body can be obtained. Boeing is caused by uneven stretching speeds at both ends and the center and shrinkage speed during heat setting.However, the intrinsic viscosity is reduced and the molecular weight is reduced to increase the fluidity of the molecules, and the unevenness developed during heat setting subsequent to stretching. It is presumed that the properties are immediately made uniform by molecular flow. Such effects can be made more remarkable by setting the molecular weight distribution and the DEG content in the above ranges. Further, the support obtained by this method has a moderately low mechanical strength, and a polyester support which does not cut during the development processing but is easily cut by a cutter of a laboratory apparatus can be produced.

In order to achieve the above intrinsic viscosity, molecular weight distribution and DEG content, the starting dicarboxylic acid diester (usually a dimethyl ester) and a diol are heated at 150 ° C. to 250 ° C. under atmospheric pressure in the presence of a transesterification catalyst. The reaction was carried out for 0.5 to 5 hours while distilling off the methanol by-produced, and the temperature was gradually increased from atmospheric pressure to 0.3 torr at a temperature of 250 ° C to 290 ° C, and the weight was increased while stirring. By conducting the condensation reaction and shortening the polycondensation time at this time, the above-mentioned polyester having a low intrinsic viscosity can be obtained. The preferred polymerization time is 0.3 to 3 hours, more preferably 0.4 to 2.5 hours, even more preferably 0.5 to 2 hours.
Time. Furthermore, as the degree of polymerization of the polymer during the polycondensation increases and the viscosity increases, the amount of current of the torque motor for stirring increases, so that the viscosity can be measured from a previously prepared calibration curve. However, this alone tends to increase the molecular weight distribution and increase the DEG content,

By these methods, the oligomer component can be removed out of the system, and the molecular weight distribution can be narrowed. At the same time, the generation of DEG can be suppressed by applying a high vacuum to shorten the reaction time, which can fall within the scope of the present invention. Thus, in the present invention, since a polyester having a narrow molecular weight distribution is used as a support, it is preferable to use a single polymer, and it is not preferable to mix two or more polymers because the molecular weight distribution is widened. The intrinsic viscosity, molecular weight distribution, and DEG content of the polyester of the present invention are all values measured after forming the support.

In the light-sensitive material of the present invention, the total thickness of all the hydrophilic colloid layers on the side having the emulsion layer is preferably 28 μm, more preferably 23 μm, further preferably 18 μm, and particularly preferably 16 μm. The film swelling speed T
1/2 is preferably 30 seconds, and more preferably 20 seconds. T
When the saturated film thickness is 90% of the maximum swelled film thickness reached when the color developing solution is processed at 30 ° C. for 3 minutes and 15 seconds, the time required for the film thickness to reach １ ／ is と. Define. The film thickness means a film thickness measured under humidity control at 25 ° C. and a relative humidity of 55% (2 days), and T1 / 2 is A Green (A.
Green) et al. Photographic Science and
Engineering (Photogr.Sci.Eng.), Volume 19, 2,124
The measurement can be performed by using a serometer (swelling meter) of the type described on pages 129 to 129. T1 / 2 can be adjusted by adding a hardener to gelatin as a binder or by changing the aging conditions after coating.
The swelling ratio is preferably from 150 to 400%. The swelling ratio is calculated from the maximum swelling film thickness under the conditions described above by the following formula:
It can be calculated by (maximum swollen film thickness-film thickness) / film thickness. Further, on the support of the present invention, the color negative photosensitive material described in Sample 201 of Example 2 of JP-A-9-146237,

The light-sensitive material thus prepared is developed. The development process includes a large lab system for processing long films formed by joining photosensitive materials, and a mini-lab system for processing one photosensitive material at a time. Meandering occurs in both, but the meandering is particularly likely to occur in the minilab system. This is because, in the minilab system, the front end is fixed to the guide plate and conveyed, but the rear end is not fixed and the electrophoresis is easy. Although the use of the silver halide photographic light-sensitive material of the present invention alone has a sufficient effect of preventing meandering, in order to further enhance the effect, 40 to 100%, more preferably 50 to 100% of the total transport rolls of these developing machines are used. 95
%, More preferably 60 to 90%, the surface roughness of the roll is preferably 1 to 500 µm, more preferably 3 to 300 µm, more preferably 5 to 100 µm. In general, a smooth roll is used on the surface of a transport roll of a developing processor in order to prevent the photosensitive layer from being damaged. In the present invention, a roll having such surface irregularities is used. This unevenness suppresses the meandering of the photosensitive material, but rather prevents the occurrence of scratches. Further, at least half or more of the transport rolls in the developing machine are used so that the diameter of the end portion is 1.01 times to 2 times the diameter of the central portion.
It is preferable to perform development processing using a drum-shaped roll having a magnification of 1.0 times, more preferably 1.05 times to 1.8 times, and still more preferably 1.1 times to 1.6 times. Thereby, the conveyance is corrected by the surface of the roll in which the end of the photosensitive material has an inclination, and the conveyance property is further improved. The diameter of the central portion of such a transport roll is preferably 2 to 30 cm, more preferably 3 to 25 cm, even more preferably 4 to 20 cm. Roll width is 3.
6 to 20 cm is preferable, 3.8 to 17 cm is more preferable, and 4 to 15 cm is further preferable. In order to further improve the transportability, the coefficient of dynamic friction between the back surface of the photosensitive material and the transport roll is set to 0.05 to 0.5, more preferably 0.1 to 0.5.
