Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic light-sensitive material which is less prone to curl and has no trouble in development processing.

[0002]

2. Description of the Related Art Generally, as photographic light-sensitive materials, sheet-like materials such as X-ray film, plate-making film and cut film, and 35 m / m width or less are stored in a cartridge. , And a roll-shaped form represented by a color or black-and-white negative film, which is used for photographing by loading the camera.

In recent years, the use of photographic light-sensitive materials has been diversified, and the speed of film transport at the time of photographing, the high magnification of photographing, and the downsizing of photographing apparatus have been remarkably advanced. In that case, the support of the photographic light-sensitive material is required to have properties such as strength, dimensional stability and thinning. Further, with the downsizing of the photographing device, there is an increasing demand for downsizing of the cartridge. In order to reduce the size of such a cartridge, there are two problems. The first problem is a decrease in mechanical strength as the film becomes thinner. The second problem is a strong winding tendency that occurs during storage over time due to miniaturization of the spool.

PET film has been considered as a substitute for TAC because of its excellent mechanical strength and dimensional stability. However, in the roll form widely used as a photographic light-sensitive material, curling curl remains strongly. Therefore, the handling property after development processing is poor, and the range of use has been limited despite the excellent properties described above. As a means for improving this, for polyester-based polymers represented by PET, heat treatment at a temperature not higher than Tg (below

[0005]

SUMMARY OF THE INVENTION It is, therefore, an object of the present invention to provide a photographic light-sensitive material comprising a support having excellent mechanical properties and having less curl curl.

[0006]

These objects of the present invention have a glass transition temperature (hereinafter referred to as Tg) of 90 ° C. or higher.
A photographic light-sensitive material having at least one light-sensitive layer on a polyester film support having a temperature of 00 ° C. or lower,
The polyester film, in the presence of water, after the film formation and before the coating of the photosensitive layer has a Tg of 40 ° C. or higher and a Tg of 40 ° C. or higher.
The polyester film is kept at about 0.1 to
This has been solved by a silver halide photographic light-sensitive material characterized by being heat-treated by holding for 1000 hours.

[0007] First, the curl habit measuring method and the terms related thereto used hereinafter will be described. (1) Core set To wrap the film around the spool and add a curl. (2) Core set curl A curl in the length direction attached by the core set. The degree of winding is Te of ANSI / ASC pH 1.29-1985.
It was measured according to st Method A and expressed in 1 / R [m] (R is the radius of the curl). (3) Glass transition temperature (Tg) Using a differential scanning calorimeter (DSC), when 10 mg of the sample film was heated at 20 ° C./min in a nitrogen stream, the straight line portion of the baseline before the transition And the temperature of the intersection obtained by extrapolating the tangent line of the inflection point of the transition region is defined as Tg.

The present invention will be described in more detail below. The heat treatment method in the present invention is carried out under high humidity at Tg-40.
It is a method of holding the polyester film at a constant temperature of not lower than Tg and not higher than about 0.1 to 1000 hours. The holding temperature is effective at Tg-40 ° C or higher and Tg or lower, but is preferably Tg-30 ° C or higher and Tg-5 ° C or lower.
Further, the holding time is 0.1 hours, but the effect is recognized, but it is 1
The effect is saturated when it exceeds 000 hours. When the polyester film is heat-treated according to the heat treatment method of the present invention, the relative humidity of the atmosphere is 20% or more, preferably 30% or more. When the relative humidity is less than 20%, the effect of shortening the heat treatment time is hardly recognized.

As an example of a specific embodiment, 100 ° C.
At temperatures above 100 ° C., superheated steam is blown onto the polyester film, and at temperatures below 100 ° C., the relative humidity of the atmosphere around the polyester film is 20%.
% Or more, or in a liquid bath whose temperature is controlled, for example, in a liquid bath filled with a polyhydric alcohol aqueous solution which can be mixed with water at an arbitrary ratio such as ethylene glycol or glycerin, or a simple substance thereof. There is a method of heat-treating a polyester film. From the viewpoint of productivity and cost, it is desirable that these heat treatments be continuously performed without cooling the film after forming the polyester film. Another example of the specific embodiment is a dichromic acid / concentrated sulfuric acid mixed solution, a chlorate / sulfuric acid mixed solution, a hypochlorite / hydrochloric acid aqueous solution, etc. It is a method of heat-treating the polyester film in an aqueous solution. According to this method, the photographic layer and the back layer can be adhered to each other without further surface treatment, and the curl can be improved and the surface treatment can be simultaneously performed. The effect of reducing curl curl as described in the present invention was effective in polyester having Tg of 90 ° C. or higher and 200 ° C. or lower. This is because the effect of this heat treatment disappears when exposed to a temperature exceeding Tg.
A polyester having a high Tg is desirable, and it is necessary to have a Tg of 90 ° C. or more as a temperature to be exposed to the highest temperature when used by general users, that is, a temperature in a vehicle in summer exceeding 80 ° C.
