Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel method for obtaining a color image using a photosensitive material.

[0002]

BACKGROUND OF THE INVENTION In a process known as conventional color photography, so-called color negatives are usually
It includes a layer that records yellow light to form a yellow dye image, a layer that records green light to form a magenta dye image, and a layer that records red light to form a cyan dye image. The developer is oxidized in the process of reducing silver halide grains containing an image to silver, and a dye image is formed by a reaction (coupling) between the oxidized product and a coupler. Undeveloped silver halide and developed silver are removed in the subsequent bleach-fixing step, and the color paper is exposed through the obtained negative dye image to a color paper through the same development, bleaching and fixing steps to obtain a color print. Also, a method is known in which after image information included in the color negative is photoelectrically read, image processing is performed to obtain image information for recording, and a color image is obtained on another print material by using the image information. . In particular, development of digital photo printers, in which the above-mentioned image information is converted into digital signals, and a photosensitive material such as color paper is scanned and exposed by a recording light modulated in accordance therewith to produce a finished print, an example of which is disclosed in
15593.

[0003] Digital photo printers are used to edit the layout of a print image, such as editing a plurality of images, dividing the image, etc., editing characters and images, and various types of images such as color / density adjustment, scaling, and contour emphasis. Processing can be performed freely, and a finished print that has been freely edited and image-processed can be output according to the application. Also, in conventional printing using surface exposure, it is not possible to reproduce all the image density information recorded on the film in terms of density resolution, spatial resolution, color / density reproducibility, etc. A print in which almost 100% of the recorded image density information is reproduced can be output.
The above methods are based on ordinary wet development, bleaching and fixing, and the process is complicated.

On the other hand, as a method for processing a photosensitive material using silver halide, a simple and quick method using heat development has been developed. Examples are 3M dry silver,
Products such as a pictrograph and a pictrostat of Fuji Photo Film Co., Ltd. are known. However, these are black-and-white or color print materials, and no known photosensitive material for photography by thermal development has been hitherto known. As a form of heat development, a method of performing heat development in the presence of a small amount of water and a base and / or a base precursor is known,
For example, Japanese Patent Publication No. 2-51494 discloses such an example. However, the image forming method described therein uses a dye-providing substance that is reducible to photosensitive silver halide and reacts with the photosensitive silver halide by heating to release a hydrophilic dye. The dye released during heat development is transferred to an image receiving material, and the transfer side is used as a color print.

[0005]

The present inventors have studied on a method of obtaining a transmission image by thermally developing a photographic photosensitive material and a method of obtaining a print image using the image information. Among them, a method was found in which, after imagewise exposing the photosensitive material, water was supplied to the photosensitive surface, and then the processing members were stacked and heat-treated. However, in the conventional water application method (for example, the method described in JP-A-7-261353), since the photosensitive material is immersed in water for a predetermined time, various chemicals contained in the photosensitive material elute into the water. There was a problem of water pollution. This problem could be solved by changing the water application method to a supply method by jetting small water droplets without immersing the photosensitive material in water (hereinafter referred to as a jet water application method). However, on the other hand, when the treatment is performed by the jet water application method, there is a new problem that the water application becomes non-uniform and density unevenness occurs in the final image.

An object of the present invention is to provide an image forming method for obtaining a color image with less density unevenness in the jet water application method using a photosensitive material for photography by a simple thermal development process.

[0007]

The above object has been attained by the following means. 1) At least photosensitive silver halide on a transparent support,

Accordingly, the water jumps out from the plurality of nozzle holes with the displacement of the nozzle and adheres to the photosensitive material.

At this time, a plurality of nozzle holes for injecting water are formed,
Since the photosensitive material is arranged linearly at regular intervals along the direction that intersects the direction of transport of the photosensitive material, it is possible to deposit water over a wide area on the photosensitive material being conveyed by a single displacement by the actuator. Become.

As described above, the particle diameter is determined by the nozzle hole,
Further, since the gas is not mixed with the liquid, there is no variation in the particle size. Further, since the nozzle holes are arranged in a straight line at regular intervals, the dispersion in the landing position is also eliminated. Therefore, these variations do not hinder the uniformity of water on the surface.

Further, since the plurality of nozzle holes are arranged linearly at regular intervals along a direction intersecting with the direction in which the photosensitive material is conveyed, there is no need to scan the nozzles on a two-dimensional plane. A large area can be provided in a short time.

Further, the photosensitive material does not come into contact with the nozzle having the nozzle hole, so that clogging and contamination are eliminated.
The durability is improved and the required accuracy of the alignment can be low. On the other hand, since it is only necessary to form a plurality of nozzle holes in the nozzle, the integration technique is not required, and the manufacturing of the application device can be performed at low cost.

In addition, when a plurality of nozzle rows in which a plurality of nozzle holes are linearly arranged at regular intervals in a direction intersecting with the direction in which the photosensitive material is conveyed are arranged in a zigzag pattern on the nozzles, the number is small. A large number of liquid droplets can be attached to the photosensitive material at the number of times of displacement, and can be closest packed or applied multiple times, so that the applied amount can be increased and uniformity can be improved.

(Displacement along the arrow B direction which is the normal direction of the head plate 322). Then, as the head plate 322 is displaced toward the photosensitive material 16 side, water droplets L fly out of the plurality of nozzle holes 324 as shown in FIG.

This modified example also has the same effect as the first embodiment, except that a plurality of nozzle holes 324 are arranged at regular intervals in a straight line along a direction intersecting the direction of conveyance of the photosensitive material 16. However, since a plurality of rows are arranged in a staggered manner on the head plate 372, a large number of water droplets can adhere to the photosensitive material 16 with a small number of displacements and can be applied in the closest packing or a plurality of times. Thus, the uniformity can be improved.

Next, a modification of the application device 310 according to the second embodiment of the present invention is shown in FIGS. 9B and 9C, and will be described below.

A pattern in which two nozzle rows 374 arranged linearly in a direction intersecting with the 16 transport directions are arranged in a staggered manner is continuously repeated.

According to the structures of the second and third modified examples, the head plate 372 is displaced in the same manner as described above, so that the nozzle holes 32 forming the plurality of nozzle rows 374 are formed.
4, water can jump out from each of them, and water can be closest packed or applied a plurality of times on the photosensitive material 16, so that the amount of application and the uniformity can be improved.

In this embodiment, the photosensitive material 16 and the image receiving material 108 are used as image recording materials, and after exposure, the photosensitive material 16 is conveyed so as to be located outside the image receiving material 108.

The photosensitive member used in the present invention includes at least three types of photosensitive layers having different spectral sensitivities and different hues of the coloring dyes. Each photosensitive layer may be divided into a plurality of silver halide emulsion layers having substantially the same color sensitivity but different sensitivities. The three types of photosensitive layers are preferably layers sensitive to any one of blue light, green light, and red light. This arrangement order is generally the order of a red photosensitive layer, a green photosensitive layer, and a blue photosensitive layer in order from the support side.

In the present invention, the silver halide, the dye-donating coupler and the color developing agent may be contained in the same layer, but they may be added separately in separate layers as long as they can react. For example, when the layer containing the color developing agent and the layer containing silver halide are formed as separate layers, the raw storability of the light-sensitive material can be improved. The relationship between the spectral sensitivity of each layer and the hue of the coupler is arbitrary, but if a cyan coupler is used for the red photosensitive layer, a magenta coupler is used for the green photosensitive layer, and a yellow coupler is used for the blue photosensitive layer, it can be directly applied to conventional color paper.

An example of a preferred embodiment of the present invention is that after forming a color image by thermal development, the image information is transmitted by using a diffused light and a CCD image sensor without performing an additional process of removing the remaining silver halide and developed silver. After reading photoelectrically by density measurement and converting it to digital signal,
The image processing is performed, and the image is output by a heat development color printer, for example, a Pictography 3000 manufactured by Fuji Photo Film Co., Ltd. In this case, a good print can be obtained quickly without using the processing solution used in conventional color photography. Also, in this case,
Since the digital signal can be arbitrarily processed and edited, the photographed image can be freely modified, deformed, processed and output.
