The present invention relates to a method for producing a silver halide photographic material, and more specifically to a method for producing a silver halide photographic material, which has a polyolefin resin-coated paper coated with a polyolefin resin as a support using paper mainly composed of natural pulp as a substrate, and halogenated A method for producing a silver halide photographic material coated with a silver photographic constituent layer, more specifically, a silver halide photographic constituent layer having good adhesion on the polyolefin resin surface of the support and having uniform coating properties. The present invention relates to a method for producing a silver halide photographic material having as a support a polyolefin resin-coated paper which is of good quality and shows no uneven coating. Usually, a silver halide photographic material is composed of a support and a silver halide photographic constituent layer provided on the support. Such silver halide photographic constituent layers include a silver halide photographic emulsion layer, a protective layer, a subbing layer, an intermediate layer or color mixing prevention layer, an antihalation layer or filter layer, an ultraviolet absorbing layer, etc., and combinations thereof. It is what was done. For example, a single silver halide photographic material has a silver halide photographic emulsion layer and its protective layer on a support. In addition, multilayer silver halide color materials consist of a blue-sensitive silver halide photographic emulsion layer and an intermediate layer, a green-sensitive silver halide photographic emulsion layer and an ultraviolet absorbing layer, a red-sensitive silver halide photographic emulsion layer and a protective layer, on a support. etc. are provided in order and arranged in multiple layers. On the other hand, supports for silver halide photographic materials have conventionally been made of films such as polyethylene terephthalate film, cellulose triacetate film, and polystyrene, paper based on natural pulp, and resins capable of forming films on both sides.
Hydrophobic supports such as resin-coated papers, many coated with polyolefin resins, are well known. especially,
As a support for photographic printing paper, polyolefin resin-coated paper is increasingly being used in place of the conventionally used baryta paper. The reason for this is that polyolefin resin-coated paper used as a photographic support is hydrophobic, so processing liquids penetrate into the base paper layer during the development and fixing processes of photographic paper, compared to baryta paper. This is because the processing time for washing, drying, etc. can be shortened. By the way, when producing a silver halide photographic material by using a polyolefin resin-coated paper having a hydrophobic surface as a support and coating a silver halide photographic constituent layer on the support, the hydrophobic polyolefin resin of the support is It is well known that the surface of a hydrophobic polyolefin resin requires some kind of treatment in order to improve the adhesion between the resin surface and the silver halide photographic constituent layer. One of the most economical and effective methods to provide good adhesion is to electron bombard the hydrophobic polyolefin resin surface. Electron bombardment is also known as corona discharge treatment. The method of electron bombarding the surface of hydrophobic polyolefin resin is as follows:
For example, it is described in British Patent No. 971058, British Patent No. 1060526, etc. In addition, in order to further strengthen the adhesion between the hydrophobic polyolefin resin surface and the silver halide photographic constituent layer by subjecting the hydrophobic polyolefin resin surface of the support to electron impact treatment, it is necessary to within, preferably
It is necessary to coat the silver halide photographic constituent layer on the hydrophobic polyolefin resin surface of the electron-impact-treated support within 30 minutes, particularly preferably within several seconds. However, using a polyolefin resin-coated paper whose substrate is paper mainly composed of natural pulp as a support, a silver halide photographic constituent layer is formed within 30 minutes after electron impact is applied to the polyolefin resin surface of the support. It has become clear that silver halide photographic materials produced by coating, although good adhesion of the silver halide photographic constituent layers to the support, are produced, but suffer from certain serious drawbacks. That is, after applying electron bombardment to the polyolefin resin surface of the support
If the silver halide photographic constituent layer is applied within 30 minutes, the coatability of the silver halide photographic constituent layer to the polyolefin resin support surface will be uneven, and the silver halide of the finished silver halide photographic material will be uneven. The problem is that coating unevenness occurs in the photographic constituent layers. Since this coating unevenness is strongly influenced by the electron impact treatment, it will be simply referred to as corona coating unevenness hereinafter. In particular, corona coating unevenness occurring in the silver halide photographic emulsion layer is more clearly observed when the silver halide photographic material is subjected to development treatment after uniform exposure. Needless to say, uneven corona coating causes a significant deterioration in the performance of photographic paper. According to the studies conducted by the present inventors, it has become clear that this uneven coating of corona occurs due to the following situation. First, corona coating unevenness is noticeable when a silver halide photographic constituent layer is coated on the polyolefin resin surface of the support within a short period of time, for example, up to one hour after electron bombardment. If a long time has passed (for example, 1 to 2 days) after the electron impact treatment,
If a silver halide photographic constituent layer is coated on this electron impact polyolefin resin surface, corona coating unevenness will not be so severe. Although uneven corona coating can be avoided by holding the holding time, it becomes an obstacle in the manufacturing process of silver halide photographic materials. That is, in order to avoid uneven corona coating, the support must be stored for a sufficient period of time after electron impact, while the silver halide photographic constituent layers must be stored for about 1 hour after electron impact in order to obtain good adhesion to the support. The coating must be applied to the polyolefin resin coated paper support within ~2 days. Secondly,
Even if a silver halide photographic constituent layer is coated within 30 minutes after electron impact is applied to the polyolefin resin-coated paper surface of the support to produce a silver halide photographic material, corona coating unevenness is caused by a single problem. It is less severe in silver halide photographic materials, and is more pronounced in multilayer silver halide photographic materials comprising at least two or more silver halide photographic emulsion layers, such as multilayer silver halide color photographic materials. That is, within 30 minutes after electron impact is applied to the polyolefin resin-coated paper surface of the support, a blue-sensitive silver halide photographic emulsion layer containing a yellow coupler, a color mixing prevention layer, and a magenta coupler are sequentially applied adjacent to the support. A multilayer silver halide color photograph manufactured by simultaneously coating six layers of a green-sensitive silver halide photographic emulsion layer containing a UV absorption layer, a red-sensitivity silver halide photographic emulsion layer containing a cyan coupler, and its protective layer from a multilayer coating hopper. In materials,
Corona coating unevenness is noticeable in the green-sensitive silver halide photographic emulsion layer, less severe in the blue-sensitive silver halide photographic emulsion layer, and even milder in the red-sensitive silver halide photographic emulsion layer. However, as prior art regarding problems and improvements in producing a silver halide color photographic material by coating a silver halide color photographic constituent layer within 30 minutes after applying electron bombardment to the hydrophobic surface of the support, is described in Special Publication No. 47-51905. According to this document, the problem is that dye spots occur in silver halide color photographic materials, and this problem is to be improved by using a specific optical sensitizing dye. However, using a polyolefin resin-coated paper as a support made of paper whose main component is natural pulp and coated with a polyolefin resin, silver halide is deposited within 30 minutes after electron impact is applied to the polyolefin resin surface of the support. It was still insufficient to solve the corona coating unevenness that occurs in silver halide photographic materials manufactured by coating photographic constituent layers. Therefore, the object of the present invention is, first, to have a polyolefin resin-coated paper as a support, which is made of paper mainly composed of natural pulp and coated with a polyolefin resin, and to provide a paper coated on the support. An excellent silver halide photographic material with good adhesion of the silver halide photographic constituent layers on the support surface and uniform coating properties with no or reduced coating unevenness is a problem in the manufacturing process. The object of the present invention is to provide a method for producing the same without causing any disadvantages. Second, it has a polyolefin resin-coated paper as a support, which is made of paper whose main component is natural pulp and is coated with a polyolefin resin, and at least two coated sheets are simultaneously coated on the support from a multilayer coating hopper. The multilayer silver halide photographic constituent layer consisting of the above silver halide photographic emulsion layer has good adhesion on the support surface and has uniform coating properties, with no or reduced coating unevenness. It is an object of the present invention to provide a method for producing silver halide photographic materials without causing obstacles or disadvantages in the production process. Furthermore, another object of the present invention is to significantly enhance not only the adhesion of the silver halide photographic constituent layer on the support surface, but also the hardness thereof, and the coating property to be uniform, so that coating unevenness is not observed. A method for producing an excellent silver halide photographic material having as a support a polyethylene resin-coated paper based on a paper based on natural pulp with no or reduced natural pulp, without causing any obstacles or disadvantages in the production process. It is to provide. As a result of intensive studies, the present inventors have found that the object of the present invention is to have a polyolefin resin-coated paper as a support, which is made of a paper mainly composed of natural pulp and coated with a polyolefin resin, and to have a halogenated paper on the support. When manufacturing silver halide photographic materials with silver photographic constituent layers, the light scattering coefficient of natural pulp is
Natural pulp of 400 cm 2 /g or more is used in an amount of 40% or more by dry weight based on the total pulp used, and a silver halide photographic constituent layer is applied within 30 minutes after electron impact is applied to the polyolefin resin surface of the support. It turns out that this can be achieved to a great extent. Here, the light scattering coefficient of natural pulp is measured by the method described below. That is, natural pulp was beaten to 300 ml according to the Canadian standard form of JIS P-8121 "Pulp freeness test method" according to the method using a beader of JIS P-8210 "Method of testing the strength of paper pulp". , JIS
Ten sheets of 80 g/m 2 hand-made paper are prepared using a hand-sheeting machine according to P-8209 "Hand-sheeted paper preparation method for pulp testing", the water is squeezed out using a hand press, and the paper is dried at 110°C using a drum dryer. This hand-made paper was processed according to JIS P-8111 "Pretreatment of test paper", and one sheet of the hand-made paper was placed on a black backing board according to JIS P-8138 "Paper opacity test method". Stack them and measure their reflectance, and take the average value of the reflectance of each of the 10 sheets as Ro.Next, stack 10 sheets of this handmade paper without using a backing black board and measure its reflectance.
Let's call it Roo. The handmade paper used for this measurement was dried at 105℃ for 3 hours using an open dryer, and the JIS
Measure the absolute dry basis weight according to P-8124 “Measurement method of paper metric basis weight”. This is assumed to be W (g/m 2 ). Using RO, Roo, and W obtained above, calculate the light scattering coefficient (cm 2 /g) using the following formula. Furthermore, the effect of the present invention is that as a substrate paper for polyolefin resin-coated paper (hereinafter simply referred to as base paper),
This effect is better exhibited by using paper having a surface resistivity of 6.3×10 8 Ω or more, preferably 1.0 to 10 9 Ω or more, at a temperature of 20° C. and a relative humidity of 65%. Note that the surface resistivity of paper is determined when the sample is heated at 20°C.
After keeping the sample conditions constant by storing it in a constant temperature and humidity chamber with a relative humidity of 65% for 48 hours, the resistance of the surface of the paper sandwiched between concentric circular electrodes with a diameter of 5 cm and a diameter of 7 cm was measured, and the resistance R = ∫ 3 .. 5 2 . 5 ρsdr/2πr(ρs;
It is calculated from the relationship of surface resistivity). Furthermore, silver halide photographic materials that use polyolefin resin-coated paper as a support tend to attract static electricity and dust during production or handling, causing various troubles. Partial fogging called static marks, which is extremely unpleasant due to photographic characteristics, may occur in the photographic emulsion layer. For this purpose, water-soluble chlorides such as sodium chloride and calcium chloride, which have good compatibility with various hydrophilic polymers such as gelatin, carboxy-modified polyvinyl alcohol, and starch, are usually added to the base paper layer. Conventionally, it has been carried out to contain these hydrophilic polymers in the form of size press or tab size. Also, in some cases, water-soluble sulfates such as sodium sulfate are used with starch for this purpose. Furthermore, if necessary, a hydrophilic colloid layer called a back coat layer with antistatic and anti-curling properties is coated on the back side of the support, that is, on the side of the support opposite to the support side on which the silver halide photographic constituent layer is provided. It is also known to provide layers. However, in order to prevent static electricity on polyolefin resin-coated paper, a conductive agent is contained in the base paper layer mainly composed of natural pulp, so that the surface resistance of the base paper increases at 200℃.
When the resistance decreases to 6.3×10 8 Ω or less at a temperature of 65% relative humidity, the effects of the present invention, that is, the effects of improving corona coating unevenness and improving adhesion are no longer significant. Meanwhile, as a base paper, temperature 20℃, relative humidity 65
It has been found that the effects of the present invention can be more significantly exhibited by using paper having a surface resistance of 6.3×10 8 Ω or more, preferably 1.0×10 9 or more. That is, electron bombardment was applied to the hydrophobic surface of a polyolefin resin-coated paper whose substrate was paper.
In silver halide photographic materials manufactured by coating the silver halide photographic constituent layer within 30 minutes, the coating properties of the silver halide photographic constituent layer are extremely uniform, and coating unevenness is not observed or is significantly reduced. Not only does it significantly improve adhesion on the support surface, but it also improves the hardening of silver halide photographic constituent layers containing a gelatin-based hydrophilic organic colloid layer and a gelatin hardener. It has become clear that it can be significantly strengthened. The above is understood to be completely different in spirit from the present invention and the prior art described in Japanese Patent Publication No. 47-51905, which states that it is advantageous to add an antistatic agent to the substrate layer. . Therefore, a preferred embodiment of the present invention is a paper whose main component is natural pulp, in which natural pulp with a light scattering coefficient of 400 cm 2 /g or more is used in an amount of 40% or more by dry weight based on the total pulp used, and Temperature 20℃, relative humidity
A polyolefin resin-coated paper with a paper substrate having a surface resistivity of 6.3×10 8 Ω or more at 65% was used as a support, and one side of the support was subjected to corona discharge, and then halogen was removed within 30 minutes. A silver oxide photographic constituent layer is coated, and a back coat layer consisting of a hydrophilic organic colloid layer is coated on the other side (back side) of the support. The present invention also relates to a multilayer silver halide photographic material comprising at least two silver halide photographic emulsion layers having as a support a polyolefin resin-coated paper whose substrate is paper mainly composed of natural pulp, particularly a multilayer halogen color photographic material. Useful in the production of photographic materials. Within 30 minutes after electron bombardment on the polyolefin resin-coated paper side of the support, a blue-sensitive silver halide emulsion layer containing a yellow coupler, a color mixing prevention layer, and a magenta coupler are sequentially applied adjacent to the support. including a green silver halide photographic emulsion layer and an ultraviolet absorbing layer,
In a multilayer silver halide color photographic material manufactured by coating six layers of a red-sensitive silver halide photographic emulsion layer containing a cyan coupler and its protective layer simultaneously from a multilayer coating hopper, in the green-sensitive silver halide photographic emulsion layer, This is because, although corona coating unevenness occurs significantly, the manufacturing method of the present invention can significantly reduce corona coating unevenness. The base paper used in the practice of the present invention is one in which natural pulp having a light scattering coefficient of 400 cm 2 /g or more is used in an amount of 40% or more by dry weight based on the total pulp used.
If necessary, paper made by mixing natural pulp with a light scattering coefficient of 400 cm 2 /g or less may be used, and paper made by mixing synthetic pulp or synthetic fiber other than natural pulp may also be used. . Natural pulps with a light scattering coefficient of 400 cm 2 / g or more used in the practice of the present invention include softwood bleached sulfite pulp (NBSP), softwood bleached kraft pulp ( NBKP), hardwood white sulfite pulp (LBSP), hardwood bleached kraft pulp (LBKP)
and their mixed pulps are advantageously used, and the bleaching treatments include conventional bleaching treatments such as chlorine, hypochlorite and chlorine dioxide bleaching as well as alkaline extraction or treatment and optionally hydrogen peroxide, peroxide and Natural pulps that have been subjected to peroxide bleaching treatment using acetic acid, etc., or a combination thereof are advantageously used, and various kinds of pulps such as natural pulps that have been treated with anthraquinone compounds as cooking aids can be used, but in particular 430 cm Natural pulps having a light scattering coefficient of 2 /g or more are preferred. Also,
The amount of natural pulp that has a light scattering coefficient of 400cm 2 /g or more is 40% by dry weight per total pulp used.
% or more, but it is particularly preferable to use 50% or more. Examples of the method of electron bombarding the surface of the polyolefin resin-coated paper used in the practice of the present invention include the methods described in British Patent No. 971058 and British Patent No. 1060526. Any suitable corona discharge or electron impact device (e.g., U.S. Pat. No. 2,864,755;
284756) can be used. In the present invention, a silver halide photographic constituent layer is coated on the surface of a hydrophobic polyolefin resin of a support within 30 minutes, preferably within 30 seconds, and more preferably within several seconds after the surface of the hydrophobic polyolefin resin is subjected to corona discharge treatment or electron bombardment. Advantageously, it is carried out. For example, in a preferred embodiment of the invention, a continuously running support of polyolefin resin-coated paper is passed through a first section where the polyolefin resin surface is bombarded with electrons, and then passed to a second section where A silver halide photographic constituent layer is applied to the electron impact surface. Using such a method, the time between electron bombardment and application of the silver halide photographic constituent layer is generally less than a few seconds, and depending on the operating speed, it can be carried out in a fraction of a second.
