DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming an image on a silver halide color photographic light-sensitive material by scanning exposure and a silver halide color photographic light-sensitive material used therefor. The present invention relates to an image forming method and a silver halide color photographic light-sensitive material used therefor.

In addition, the present invention relates to a method for producing a color proof by a method of producing a color image which is preferably used for proofreading, which is performed by scanning exposure from halftone image information obtained by color separation and halftone image conversion in a plate making / printing process. is there.

[0003]

2. Description of the Related Art Conventionally, as a method of obtaining a color proof from a plurality of black and white halftone images obtained by color separation and halftone image conversion in a color plate making and printing process, a silver halide color photographic material having a white support has been proposed. A method for producing a color proof using the method described in
6-104335, 62-280746, 62
-280747, 62-280748, 62-
Nos. 280747 and 62-280750.

[0004] On the other hand, plate making methods for converting an image into a digital signal and editing the image on a computer without using the above-described halftone dot black and white film have come into wide use. By digitizing the image information, the image processing, the image can be quickly sent to a remote place, or the image in which the layout, the color tone, etc. of the image are changed can be quickly edited.

As a method of outputting an image edited in this way as a color proof, a method of scanning and exposing a color paper with a laser is known, but has various practical problems in practical use.

For example, in order to output as a printing proof, it is necessary to output to a relatively large area, and it takes a long time to scan and expose it, and productivity is remarkably high. Will be inferior.

Further, when an apparatus capable of performing scanning exposure for a large-format color proof is constructed, it becomes a very large apparatus, and cannot be used in a place where the installation area is limited. There has been proposed a method of winding a photographic material, rotating the photographic material, and performing scanning exposure with a laser. However, in the method of rotating a silver halide photographic material with a drum, it is necessary to expose a high-definition image or to increase the number of rotations of the drum in order to further improve productivity. There are problems that arise.

In addition, efforts have been made to increase exposure productivity by using a technique of simultaneously irradiating a plurality of beam spots onto a silver halide photographic material using a plurality of lasers having the same wavelength. In reality, even if the type of laser light source is the same, there are individual differences, slight deviation in oscillation wavelength, uneven intensity, etc. It causes quality variation.

In particular, when a halftone dot image is to be output by exposure, it is apparent that a non-uniform image is a fatal defect. In addition, there is a problem in that when a plurality of identical images are output, different finishes are obtained.

Japanese Patent Application Laid-Open No. Hei 4-330337 discloses a method of exposing a silver halide photographic material by performing scanning exposure with a semiconductor laser. There is no mention of this problem.

In the present invention, in performing the scanning exposure on the silver halide photographic light-sensitive material, the silver halide photographic light-sensitive material is set so as to be wound around a rotating drum, and is synchronized with the rotation of the rotating drum in accordance with image information. Laser exposure. The diameter of the drum can be arbitrarily set in accordance with the size of the photosensitive material to be exposed. The number of rotations of the drum can be arbitrarily set, but an appropriate number of rotations can be selected according to the beam diameter of the laser light, the energy intensity of the laser light, the writing pattern of the laser light, the sensitivity of the photosensitive material, and the like. From the viewpoint of productivity, it is preferable that scanning exposure can be performed at a higher speed, but specifically, 200 to 300 rotations per minute.
Zero rotation is preferred.

The photosensitive material may be fixed to the drum by mechanical means, or a large number of fine holes which can be sucked on the surface of the drum are provided in accordance with the size of the photosensitive material.
The photosensitive material can be sucked and brought into close contact. It is necessary to fix the photosensitive material as closely as possible to the drum in order to prevent troubles such as unevenness of the image.

As the laser for exposing the photosensitive material, various conventionally known lasers can be used.
A gas laser can provide a high output, but requires a large and expensive device and a modulator. On the other hand, semiconductor lasers have features such as small size, low cost, and long life. Some semiconductor lasers have an oscillation wavelength from the visible part to the infrared.

As an example of a gas laser that emits visible light, a helium-cadmium laser (441.6 n
m), an argon ion laser (514.4 nm), a helium neon laser (632.8 nm), and the like. As a semiconductor laser, AlGaInAs
(670 nm), GaAlAs (750 nm), GaAs
lAs (760-850 nm) and the like, but are not limited thereto.

In the present invention, a plurality of laser beams having the same wavelength are used to simultaneously irradiate a plurality of beam spots onto a silver halide photographic material. The plural may be two or more, and there is no particular upper limit.

By arranging a plurality of lasers to form a plurality of beam spots, it is possible to simultaneously expose a plurality of spots even in a drum rotating system, thereby increasing the productivity of exposure.

When the laser intensity is high and the laser beam is divided and used as a plurality of beam spots, the wavelength and the intensity of each beam essentially depend on the fluctuation of one laser light source. The problem is not a significant defect.

In the present invention, the same wavelength is the same wavelength because the difference between the wavelengths of the individual laser light sources is 10 nm or less. The wavelength of the laser fluctuates depending on the environment such as the temperature and operating conditions, but a wavelength difference of 10 nm or less when measured under the same environment and conditions.

One or more emulsions may be contained in the silver halide light-sensitive material. However, from the viewpoint of the present invention, it is preferable to form a full-color image. Therefore, at least a yellow image, a magenta image, and a cyan image It is preferable to contain at least three emulsion layers having different spectral sensitivities to form the emulsion. With respect to laser exposure at a wavelength corresponding to each spectral sensitivity, at least one of the laser exposures is performed by a rotating drum method. Preferably, all necessary laser exposures are performed on a rotating drum system.

The reflective support of the light-sensitive material of the present invention is the weight per 1 m ² is 130g or less, more preferably is the weight per 1 m ² is 70～120G. When the weight is smaller than 70 g, problems such as jamming are liable to occur in conveyance such as winding around a drum.
If it is larger than g, the problem that the beam is not focused on the light-sensitive material surface due to the rotation of the rotating shaft due to the high-speed rotation of the drum is likely to occur.

The color light-sensitive material of the present invention has at least a yellow image forming silver halide emulsion layer, a magenta image forming silver halide emulsion layer, and a cyan image forming silver halide emulsion layer, and is contained in each emulsion layer.

Is 0.8 or more, more preferably 1.0 or more, and 1.0 to 2.5
Is more preferred. If it is 2.5 or more, the sensitivity is significantly reduced.

For measuring the reflection density of the raw sample, a conventionally known method can be used. For example, the value of the spectral reflection density measured using a color analyzer 607 manufactured by Hitachi, Ltd. can be used.

As a method of increasing the reflection density to 0.8 or more before the development processing, a method of adding a water-soluble dye having absorption to at least a spectral sensitivity region of the silver halide emulsion and / or a method of adding the water-soluble dye to the lowermost layer or other It is preferable to provide antihalation in the layer.

The above carboxyl group, sulfonamide group,
The dye having at least one sulfamoyl group is a compound having a hydrophilic group which is substantially water-insoluble (with respect to water having a pH of 7 or less) and dissociates at a pH of 9 or more. Solid fine particle dispersion obtained by a method of dissolving in a solvent and dispersing in a gelatin solution (in the form of group particles having microscopic dimensions, the average particle diameter is preferably 10 μm or less, more preferably 1 μm or less;
m) or less in gelatin or a polymer binder, it can be contained in any photosensitive emulsion layer or non-photosensitive hydrophilic colloid layer in a photographic component layer.

The above carboxyl group, sulfonamide group,
The solid fine particle dispersion of a dye having at least one sulfamoyl group is insoluble in water and is stably present in the color photographic material. However, after the exposure, it is treated with a color developing solution (preferably at pH 9 or more). When the hydrophilic group in the dye compound is dissociated to become water-soluble or decolorized, most of the dye is lost from the color photographic material.

As the dye having at least one of a carboxyl group, a sulfonamide group and a sulfamoyl group, two or more dyes may be used, or a water-soluble dye may be used in combination depending on the purpose of use.

The content of the dye having at least one of a carboxyl group, a sulfonamide group and a sulfamoyl group is determined by measuring the reflectance of a raw sample before development measured at at least one wavelength within the exposure area for cyan image-forming silver halide. The amount can be selected and added so that the concentration becomes 0.8 or more. Specifically, generally 0.001 to 0.5 g / m
^It is preferably used to be ² .

The support preferably used in the present invention has both sides of a paper substrate coated with a resin containing a polyolefin resin as a main component. When obtained by analysis, it is preferable that the integrated value (PY value) of the power spectrum in the frequency section of 1 to 12.5 mm on the surface of the support is 2.9 μm or less. The PY value is more preferably 1.8 μm or less, and still more preferably 1.15 μm or less. The lower limit is zero.

When a support having a PY value larger than 2.9 μm is used, unevenness of the image becomes large and dot reproduction is deteriorated when the productivity is improved by increasing the number of rotations of the drum.

In order to measure the PY value, the thickness unevenness of the polyolefin-coated support is continuously measured using a film thickness continuous measuring device (for example, manufactured by Anritsu Corporation), and the obtained measurement signal is analyzed by a frequency analyzer. (For example, Hitachi Electronics:
VC-2403).

The substrate (base paper) of the support can be selected from raw materials generally used for photographic printing paper. For example, in addition to natural pulp, synthetic pulp, a mixture of natural pulp and synthetic pulp, various raw paper materials can be mentioned. In general, natural pulp mainly composed of softwood pulp, hardwood pulp, mixed pulp of softwood pulp and hardwood pulp, and the like can be widely used.

Further, additives such as a sizing agent, a fixing agent, a strength enhancer, a filler, an antistatic agent, a dye and the like generally used in papermaking may be incorporated into the support. An agent, a surface strengthening agent, an antistatic agent and the like may be appropriately applied to the surface.

The reflection support is usually 50 to 300 g / m 2.
A resin having a smooth surface having a weight of ² is used, and the resin for laminating the both surfaces is ethylene, α-olefins, for example, a homopolymer such as polypropylene, a copolymer of at least two kinds of the olefins or It can be selected from at least two kinds of mixtures of these various polymers. Particularly preferred polyolefin resins are low density polyethylene, high density polyethylene or mixtures thereof.

The molecular weight of the polyolefin resin to be laminated on the reflective support is not particularly limited, but is usually in the range of 20,000 to 200,000.

The thickness of the polyolefin resin coating layer on the side of the reflection support on which the photographic emulsion is coated is preferably 25 to 50 μm, more preferably 25 to 35 μm.

As the polyolefin used for laminating the back side of the reflection support (the reflection side of the side on which the emulsion layer is provided), a mixture of low-density polyethylene and high-density polyethylene is usually melt-laminated. This layer is generally often matted.

In forming the laminate on the front and back of the support,
In general, in order to increase the flatness of the developed photographic paper in a common environment, a method of slightly increasing the density of the resin layer on the front side or increasing the amount of lamination on the back side compared to the front side is used.

In general, the lamination on both the front and back surfaces of the reflection support can be formed by melt extrusion coating the polyolefin resin composition on the support. Further, it is preferable to apply a corona discharge treatment, a flame treatment or the like to the surface of the support or, if necessary, to the front and back surfaces. It is also preferable to provide a sub-coat layer on the surface of the surface laminate layer for improving the adhesion to the photographic emulsion, or a back coat layer on the back surface of the laminate layer for improving the printability and antistatic properties.

The polyolefin resin used for laminating the surface of the support (the surface on which the emulsion layer is provided) is preferably dispersed and mixed with 13 to 20% by weight, more preferably 15 to 20% by weight of a white pigment. As the white pigment, an inorganic and / or organic white pigment can be used, and preferably an inorganic white pigment, such as a sulfate of an alkaline earth metal such as barium sulfate, calcium carbonate, or the like. Alkaline earth metal carbonates, finely divided silica, synthetic silicate silica, calcium silicate, alumina, alumina hydrate, titanium oxide, zinc oxide, talc, clay and the like.

Among these, barium sulfate is preferred.
Calcium carbonate and titanium oxide, more preferably barium sulfate and titanium oxide. The titanium oxide may be of a rutile type or an anatase type, and one whose surface is coated with a metal oxide such as hydrous alumina or hydrous ferrite is also used.

In addition, it is preferable to add an antioxidant, a colored pigment for improving whiteness, and a fluorescent whitening agent.

Further, it is preferable to provide a hydrophilic colloid layer containing a white pigment on the reflective support, because the sharpness is improved. As the white pigment, the same white pigment as described above can be used, but titanium oxide is preferable.
It is more preferable to add a hollow fine particle polymer or a high boiling point organic solvent to the hydrophilic colloid layer containing a white pigment because sharpness and / or curl resistance can be improved.

The shape of the surface of the reflective support may be smooth or may have an appropriate surface roughness, but it is preferable to select a reflective support having a gloss close to that of a printed matter. For example, JIS B 0601-1976
Has an average surface roughness SRa of 0.30 to 3.0 μm
It is preferred to use a white support having a m.

The light-sensitive material of the present invention preferably has a surface roughness of 0.30 to 3.0 μm on the image forming surface. An agent can be contained. The layers to which the matting agent is added include a silver halide emulsion layer, a protective film, an intermediate layer,
There is an undercoat layer and the like, which may be added to a plurality of layers, and is preferably the uppermost layer of the photosensitive material.

The surface gloss on the image forming layer side of the photosensitive material preferably has a gloss close to that of a printed matter. For example, the glossiness GS of the surface of the image forming layer after treatment is measured by a method specified in JIS Z8741. (60 °) of 5 to 60 is preferred.

In a preferred embodiment of the present invention, it is preferable to form a protective layer on the outermost surface of the light-sensitive material, and to add fine powder to the protective layer. Japanese Patent Application Laid-Open No. 6-95283 describes a fine particle powder (matting agent) and a method of using the same.

In the present invention, a support of a synthetic resin film such as polypropylene, the surface of which is further coated with polyolefin, can be used.

The thickness of the reflective support is not particularly limited.
Those having a thickness of 0 to 160 μm are preferably used. Especially 9
Those having a thickness of 0 to 130 μm are more preferred. When the reflective support is thinner than 80 μm, jams are likely to occur during transport such as wrapping around a rotating drum. On the other hand, when the reflective support is thicker than 160 μm, the rotation axis is displaced during high-speed rotation of the rotary drum. There is a problem that it is difficult to focus the exposure on the surface.

The beam diameter of the infrared laser preferably used in the present invention is from 3 μm to 25 μm, more preferably from 6 to 22 μm. Although smaller than 6 μm is preferable in terms of image quality, it is difficult to adjust and the processing speed is reduced. When it is larger than 25 μm, when scanning exposure is performed with a high-speed rotating drum, unevenness is particularly large with an infrared laser, and the sharpness of an image is deteriorated. By narrowing the beam diameter according to the present invention, it is possible to produce a high-definition image without unevenness. Such a problem with the rotating drum is not mentioned at all in the above-mentioned Japanese Patent Application Laid-Open No. 4-330337. With the configuration of the present invention, for the first time,
With infrared lasers, high productivity can be achieved, and high-definition image writing without unevenness can be performed at high speed.

In the present invention, a color photosensitive material is subjected to scanning exposure based on halftone image information composed of color-separated yellow, magenta, cyan and black image information.
In the step of producing a color proof, at least a part of the halftone dot image information is such that the number of halftone dots per inch ² is 200 × 10 ³ or more when the halftone dot area ratio is 40%. It has a particularly remarkable effect when using the converted one. Preferably 300 × 10
³ or more, more preferably 400 × 10 ³ or more, especially 400
× 10 ^{3 to} 2000 × 10 ³ is preferred. The number of the halftone dots can be measured by counting halftone images captured by an optical microscope or the like.

The infrared-sensitive silver halide emulsion layer in the present invention has a spectral sensitivity maximum at a wavelength longer than 700 nm. As such a method of infrared spectral sensitization, a sensitization method using an infrared sensitizing dye is particularly preferably used.

The infrared sensitizing dye used in the present invention is not particularly limited, but may be tricarbocyanine and / or
Dicarbocyanine dyes containing a quinoline nucleus are preferred, and tricarbocyanine is particularly preferred.

Among the tricarbocyanines, particularly useful ones are represented by the following general formula [Ia] or [Ib].
