Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for forming a color squadron (more specifically, it is a method for forming a high quality color image). The present invention relates to a color image forming method that can be easily obtained.

With the recent rapid development of electronic technology, for example, high-quality color l [! It is now possible to record ii squads. Color 1 above at the same time as the casing
Recently, there has been a strong demand to produce hard copies of one sphere per surface, and in response to this demand, non-silver halide image forming systems such as thermal transfer systems and inkjet systems, and silver-based image forming systems such as instant color films have been developed. Salt imaging systems have been proposed on the market.

The non-silver halide imaging systems described above are unable to reproduce extremely high-quality color i[ii'i (g), while existing systems using instant color film also produce high-density images on film. When inputting data into a computer, it is necessary to use three types of laser light: blue, lamp color, and red.

The 1: incision method using laser beams for these three types of cypress is also disclosed in NHK Gi4dF Monthly Report, Vol. 11, Section 464 (1980), but this system is extremely difficult. Because the system is detachable and expensive, it cannot help but be said that the system has major problems in terms of easily retrieving hard copies.

In addition, the existing system of Noh (RT) involves photographing three CRTs that emit monochrome light through a mirror system, or because the CRT emits white light, the image quality of the photographed image is lower than that of the CRT. It has the disadvantage that it is determined by the image quality and the thickness of the stroke is determined by the size of the CRT.

No. 524 and Canadian Patent No. 674,082, an integrated color diffusion transfer film unit is used.

In these film units, the photosensitive element is constructed of multiple layers, and the image quality is often undesirably degraded due to the long diffusion distance of the diffusible dye.

OBJECTS OF THE INVENTION It is an object of the present invention to improve the above-mentioned conventional techniques and easily produce high-quality color images from high-quality single-stage signals recorded on high-density information recording media such as magnetic tapes, magnetic disks, and optical disks. An object of the present invention is to provide a method for forming a color image that is reproduced as a color hard copy.

Fourth aspect of the invention As a result of extensive testing to solve the above problem, the inventors of the present invention have discovered that at least three types of pigment-forming substances, each of which can release pigments or enveloping precursors with different tones, have been discovered. A mosaic layer and photosensitive silver halide YL contained in different regions and arranged in a striped or mosaic shape
A photosensitive element having a photosensitive agent is irradiated with monochromatic light through the mosaic layer, and then an alkaline processing agent is brought into contact with the photosensitive element in the presence of a developing agent to form a diffusible dye or The above-mentioned object is achieved by a color paint forming method which generates a distribution of a diffusible dye precursor and diffusely transfers at least a portion of the distribution to a receiving element to form a color image on the receiving element. I found out what to ask.

In the present invention, a conventional multi-layer groove, a photographic photosensitive layer consisting of
It is possible to shorten the diffusion distance of the light to the receiving layer compared to the case where the laser beam is used, and in addition, since monochromatic light that can print the spot diameter is used for writing information,

The basic structure is that the entire support has at least one photosensitive silver halide fL agent layer (referred to simply as a mosaic layer) and at least one photosensitive silver halogenide fL agent layer.

Mabuko: The process of the present invention requires that the exposed layer of the photosensitive element be brought into contact with the IC alkaline processing ridges in the presence of a silver halide developing agent to carry out 'fACJ'); It has the function 7 of physically or chemically adsorbing the dye or chromophore precursor 7 that diffuses from the photosensitive element, and may exist integrally with the photosensitive element during exposure. The photosensitive element may be brought into contact with the photosensitive element and integrated at the same time. After a color image is formed, the color image can be separated from the light-sensitive image, or it can be used as an integrated image.

Hereinafter, the present invention will be explained in more detail with reference to the drawings.

In the present invention, as described above, the pigment-forming substances include:
Three classes of dye-forming substances capable of releasing yellow, magenta, and cyan diffusion dyes or diffusible dye precursors are preferably used. In the present invention, if the difference in the maximum absorption wavelength of the dyes produced is within 5 nm, they are considered to be the same type of dye-forming substance even if their structures are different.

Each of these oils contains different pigment-forming substances (contained in different regions arranged in a mosaic or stripe pattern).

In the present invention, two or more of the above dye-forming substances can be mixed and used as long as they are of the same type, even if they have different structures.

FIG. 6 is a top view showing a specific example of the arrangement of the above regions, and FIG. The arrangement of the layers is shown as one row.

In the color image forming method of the present invention, the amnestic color finish or color spring precursor produced in the development process is subtracted and mixed while diffusing into the receptor layer of the receptor element to form an image. Therefore, it is preferable that the area containing all the pigment-forming substances be fine, and the finer the area, the more difficult the image quality, particularly the resolution, will be obtained.

Therefore, in the figure, the size of each microscopic region is at least ′
It is preferable that the width of the area is 1μ to 500μ, particularly 5μ to 100μ. It can also be made so small that it is impossible to distinguish the area.

The lenticular lens (Ls) is advantageous when distributing the dye-forming substance into different areas in a striped manner, as will be described in the examples below. It is advantageous to set the exposure at the desired position simply by changing the .

The dye-forming material used in the method of the present invention is capable of producing an image-wise appearance of a monolithic dye or dye precursor, in addition to producing an image-wise appearance of silver halide exposed imagewise under alkaline conditions. A wide variety of compounds can be used as long as they can form a distribution. The imagewise distribution may be a negative image or a positive image for dark-like exposure.

The dye-forming substance preferably used in the present invention is oxidized by a compound oxidized by an oxidized silver halide developer or an oxidized silver halide developer to release a diffusible dye or a diffusible dye precursor. However, under alkaline conditions, the compound oxidized by the oxidized form of the silver halide developing agent may release the diffusible dye or the diffusible dye precursor under alkaline conditions. is a compound that cannot release all of the diffusible dye precursor.

In a preferred embodiment of the invention, for example, by passing the exposed photosensitive element through a processing container,
Process G liquid is absorbed into the exposed photosensitive element from the non-viscous process liquid. Conventional techniques can also be used which allow the small amount of processing solution required to be applied virtually uniformly over the surface of the negative, for example as described in U.S. Pat. No. 3i94.138.
A liquid application device with a full capillary gap through which the processing solution passes, as disclosed in the US Pat. When layered later! The required amount of processing solution from a viscous processing composition can also be absorbed into the photosensitive element, provided that there is no layer of polymer or processing composition present between the photosensitive element and the image-receiving element. b] It is capable. However, it is preferred to use non-viscous processing solutions, as this allows the use of very simple processing equipment and handling techniques.

process! Despite the special technique for supplying the liquid to the photosensitive element, the receiving element is kept dry until it comes into front-to-front contact with the wetted photosensitive element, so that the receiving element Naturally, it is wetted only with the processing G liquid extracted from the photosensitive material.

The expression "front-to-front contact" is used herein to denote the absence of any layer of processing composition between the superimposed photosensitive element and the image receiving cavity.

The expressions "non-viscous processing solution" and "non-viscous processing composition" as used in the present invention are intended to refer to a processing solution or composition having a viscosity substantially similar to water. If the size is good, it is 100 cp or less at ℃, more preferably 1. It has a viscosity of OCp or less. Non-viscous processing compositions do not contain polymeric film-forming materials or thickening components such as those used in commercially practiced color diffusion transfer processes. In general, processing compositions of the type described in the prior literature provide non-viscous processing solutions suitable for use in the present invention by simply removing the film former. In some cases, such non-viscous compositions transfer a partially solidified layer of the processing composition to either of the exposed light-sensitive elements and image-receiving elements when the elements are separated from their superimposed relation. It may also contain a reagent whose primary function is to facilitate adhesion to the material, and since this function is not utilized in the method of the present invention, such a reagent may be omitted. In some cases, the new processing techniques of the present invention allow the concentration of one or more agents in a treatment composition to be reduced compared to the concentration when the agent is used in a viscous treatment composition. It became. The particular concentration of a given agent to be used in a non-viscous treatment composition can be readily determined by one skilled in the art by performing routine dust residue tests.

As previously mentioned, the non-viscous processing composition can be applied to the photosensitive element in a number of ways, such as by applying the non-viscous processing composition to the exposed photosensitive element by a block or head of a porous application device. This can be done by applying the processing composition to a container or by passing the exposed photosensitive element through a container of the non-viscous processing composition.

Examples of methods for bringing the photosensitive element of the present invention into contact with the non-viscous treatment bath include immersion in an alkaline treatment bath, spraying on the photosensitive element, and supplying the acid by brushing. For example, U.S. Patent No. 3,103,
No. 153, No. 3,112,685, No. 3,195
．． No. 435, No. 3,626,832, No. 3,69
No. 5,163 discloses that after a photosensitive element is passed through a tank or a container holding a processing composition, the photosensitive element is pulled out from the container and crimped at the same time or after mating with an image receiving element to form a front surface. - There is a description of a one-image transfer processor device that uses front contact, and when carrying out the present invention,
Although any of these devices may be utilized, it is particularly preferred to process using an image transfer processor of the type described in US Pat. No. 4,223,991.

Referring to the drawings, FIG. 8 il''j shows that the exposed photosensitive element 5, after being immersed in a container 7 of a non-viscous processing solution 6 for a certain period of time, is removed from the container and placed together with the dry image-receiving element 8 on pressure rollers 9 and 10. This makes front-to-front contact ((()) by passing it through between.

Since the pressure rollers 9 and 10 only press the photosensitive element 52 and the polymer 11 consisting of the receiver 8,
Compared to the rollers used in so-called self-processing cameras, in which a viscous processing liquid must be distributed between sheets, the pressure rollers 9 and 10 may be of simple construction and equipment. Prior to superimposing the photosensitive element on the dry receiving element, a device such as a squeeze roll is used to remove excess processing solution that adheres to the front and/or back surface of the photosensitive element as it is pulled out of the processing liquid 6. You can prepare.

In order to ensure that the tips and side edges of the photosensitive element and the image receiving element pass between the pressure rollers 9 and 10 without misalignment, the tips of the photosensitive element and the image receiving element are shifted in advance before passing between the rollers. It is desirable to align the leading edges of the photosensitive element and the image receiving element when they are inserted into the holding roller. A Grossener having such a device is described in the aforementioned U.S. Pat. No. 4,223,991.

Although the support for the photosensitive element according to the present invention is not necessarily required, it is suitable that the support used does not undergo significant dimensional changes during development. As the support, plastic films such as cellulose acetate film, polystyrene film, polyester film, and polycarbonate film, which are used in ordinary photographic materials, are mainly used, but paper supports can also be used. Furthermore, in order to enable development processing in a bright room, it is difficult to use a light-shielding agent such as carbon black at appropriate locations on photographic elements with various layer configurations to block light. In this case, an optical aperture of I''i of 5 to 108 degrees is required.The appropriate position of the light shielding varies depending on the layer structure of the photographic element, but may be in the center of the support or/and on the opposite side of the silver halide emulsion layer. A light-pleasing agent such as carbon black or titanium oxide may be added to the composition to give an optical density of 5 to 10.

As supports for single-layer image-receiving elements, polymeric films, wood fibers such as paper, metal sheets and foils, glass, and ceramics, tatami mats can be used. In order to improve the adhesive strength, antistatic property, dimensional stability, peeling resistance, hardness, friction resistance, and/or properties of the support surface, one or more undercoat layers are provided. are doing.

Common useful polymeric film supports include films of cellulose nitrate and cellulose esters, e.g.
i Cellulose triacetate and diacetate, polystyrene, polyamide, homo- and copolymers of vinyl chloride, poly(vinyl acetal), polycarbonate, homo- and copolymers of olefins, such as polyethylene and polypropylene, and dibasic aromatics Polyesters of carboxylic acids and 21-alcohols, such as poly(ethylene terebutanoate).

Common useful paper supports include polymers of partially acetylated or parita and/or polyolefins, especially α-olefins having from 2 to 10 carbon atoms, e.g. It is coated with polyethylene, polypropylene, a copolymer of ethylene and hyperpylene, etc.

Image reception, v: Particularly useful as a support that composes the element is preferably one that does not disgrace the good background of transfer art dealers,
It is preferable to have a reflectance of about 80 coefficients or more. Particularly preferred are polymer films containing white pigments such as Tio2, kaolin, mica, barium sulfate, and zinc oxide. In addition, to prevent the silver photosensitive layer from fogging due to light, Research Disclosure 1833 was used.
It is also possible to apply an opaque treatment to the support as described in No. 6.
