TECHNICAL FIELD 
     The present disclosure relates to a photosensitive film, a photosensitive element, a method for producing a laminate, and the like. 
     BACKGROUND ART 
     In the production of laminates that can be used as wiring boards and the like, resist patterns are formed in order to obtain desired wirings. 
     The resist pattern can be formed by exposing and developing a photosensitive film that is a film-shaped photosensitive resin composition.

     SUMMARY OF INVENTION 
     Technical Problem 
     When a cured product pattern that can be used as a resist pattern is formed by using a photosensitive film, the cured product pattern is formed while a photosensitive resin composition is filled in a recessed portion having a circular cross-section (circular hole) in some cases. However, in a conventional photosensitive film, a cured product pattern is formed in a state where a void is generated in a recessed portion, and followability (fillability) with respect to the shape of the recessed portion is not sufficient, in some cases. Furthermore, conventionally, although a photosensitive film having a thickness of 25 μm is usually used, it is required to reduce the thickness of the photosensitive film to 20 μm or less for the purpose of reducing the thickness of a laminate, or the like, in some cases. However, when the thickness of the photosensitive film is reduced in this way, the amount of the photosensitive resin composition for filling the recessed portion is decreased, and thus a cured product pattern is likely to be formed in a state where a void is generated in the recessed portion. Therefore, the photosensitive film is required to have excellent followability with respect to the recessed portion having a circular cross-section even in a case where the thickness of the photosensitive film is 20 μm or less. 
     An object of an aspect of the present disclosure is to provide a photosensitive film having excellent followability with respect to a recessed portion having a circular cross-section as a photosensitive film having a thickness of 20 μm or less. An object of another aspect of the present disclosure is to provide a photosensitive element using this photosensitive film. An object of still another aspect of the present disclosure is to provide a method for producing a laminate using the above-described photosensitive film or photosensitive element.

     An aspect of the present disclosure relates to a photosensitive film containing (A) a binder polymer, (B) a photopolymerizable compound, (C) a photopolymerization initiator, and (D) a pyrazoline compound, in which a thickness of the photosensitive film is 20 μm or less. 
     Such a photosensitive film has excellent followability with respect to a recessed portion having a circular cross-section although the thickness of the photosensitive film is 20 μm or less. 
     Another aspect of the present disclosure relates to a photosensitive element including a support, and a photosensitive resin layer disposed on the support, in which the photosensitive resin layer is the above-described photosensitive film. 
     Still another aspect of the present disclosure relates to a method for producing a laminate, the method including a disposing step of disposing a photosensitive resin layer on a base material by using the above-described photosensitive film or the above-described photosensitive element, a step of photo-curing apart of the photosensitive resin layer, and a step of removing at least a part of an uncured area of the photosensitive resin layer to form a cured product pattern.

     DESCRIPTION OF EMBODIMENTS 
     Hereinafter, embodiments of the present disclosure will be described in detail. However, the present disclosure is not limited to the following embodiments. 
     In the present specification, a numerical range that has been indicated by use of “to” indicates the range that includes the numerical values which are described before and after “to”, as the minimum value and the maximum value, respectively. The numerical range “A or more” means A and a range of more than A. The numerical range “A or less” means A and a range of less than A. In the numerical ranges that are described stepwise in the present specification, the upper limit value or the lower limit value of the numerical range of a certain stage can be arbitrarily combined with the upper limit value or the lower limit value of the numerical range of another stage. In a numerical range described in the present specification, the upper limit value or the lower limit value of the numerical range may be substituted by a value shown in Examples. “A or B” may include either one of A and B, and may also include both of A and B. Materials listed as examples in the present specification can be used singly or in combinations of two or more kinds, unless otherwise specified. When a plurality of substances corresponding to each component exist in the composition, the content of each component in the composition means the total amount of the plurality of substances that exist in the composition, unless otherwise specified. The term “layer” includes a structure having a shape which is formed on a part, in addition to a structure having a shape which is formed on the whole surface, when the layer has been observed as a plan view. The term “step” includes not only an independent step but also a step by which an intended action of the step is achieved, even though the step cannot be clearly distinguished from other steps. The term “(meth)acrylate” means at least one of “acrylate” and “methacrylate” corresponding thereto. The same applies to other analogous expressions such as “(meth)acrylic acid”. The “alkyl group” may be linear, branched, or cyclic, unless otherwise specified. 
     In the present specification, the solid content of a photosensitive resin composition refers to a non-volatile content of a photosensitive resin composition excluding volatile substances (such as water and a solvent). That is, the solid content refers to a component remaining without volatile in drying of the photosensitive resin composition (a component other than a solvent) and also includes a component in a liquid, syrupy, or waxy state at room temperature (25° C.). 
     &lt;Photosensitive Film and Photosensitive Resin Composition&gt; 
     A photosensitive film of the present embodiment contains (A) a binder polymer, (B) a photopolymerizable compound, (C) a photopolymerization initiator, and (D) a pyrazoline compound, in which a thickness of the photosensitive film is 20 μm or less. The photosensitive film of the present embodiment is a photosensitive resin composition having a film shape, and can be obtained by molding a photosensitive resin composition of the present embodiment into a film shape. The photosensitive resin composition of the present embodiment can contain the same components as those contained in the photosensitive film of the present embodiment. 
     Although the thickness of the photosensitive film of the present embodiment is 20 μm or less, the photosensitive film has excellent followability (circular hole followability, fillability) with respect to a recessed portion (for example, a diameter of 200 μm and a depth of 8 μm) having a circular cross-section (for example, substantially true circle). According to the photosensitive film of the present embodiment, in evaluation described in Examples, for example, followability of less than 20000 μm 2  (preferably 15000 μm 2  or less) can be obtained. 
     The present inventors have speculated factors for excellent followability obtained by the photosensitive film and the photosensitive resin composition of the present embodiment as follows. However, the factors are not limited to the contents to be as follows. That is, by using the component (D) when the component (A), the component (B), and the component (C) are used in combination, various physical properties (such as crystallinity and a melting point) of the component (D) suitably acts in a thermal process (such as lamination) when the photosensitive film is laminated on the base material with a recessed portion having a circular cross-section. Thus, since flowability suitable in the thermal process is easily obtained, excellent followability is obtained even when the thickness of the photosensitive film is 20 μm or less (even when the amount of the photosensitive resin composition for filling the recessed portion is small). 
     The photosensitive film of the present embodiment is sufficient to have excellent followability when the photosensitive film is laminated on the base material with a recessed portion having a circular cross-section, and may be laminated on a base material with a recessed portion having a cross-sectional shape different from a circular shape, a base material having no recessed portion, or the like. 
     Incidentally, when a cured product pattern that can be used as a resist pattern is formed by using the photosensitive film or the photosensitive resin composition, a cured product pattern having a straight line area and a straight space area adjacent to the line area is formed in some cases. Further, in the case of forming a cured product pattern having a width of the space area (space width) smaller than a width of the line area (line width), excellent resolution is required as a property with which the line area and the space area are favorably formed, in some cases. Furthermore, in the case of forming a cured product pattern having a line width smaller than a space width, excellent adhesiveness is required as a property with which the line area and the space area are favorably formed, in some cases. 
     According to the photosensitive film or the photosensitive resin composition of the present embodiment, it is possible to obtain excellent resolution in the case of forming a cured product pattern having a space width smaller than a line width. According to the photosensitive film of the present embodiment, in evaluation described in Examples, for example, resolution of 15 μm or less can be obtained. 
     According to the photosensitive film or the photosensitive resin composition of the present embodiment, it is possible to obtain excellent adhesiveness in the case of forming a cured product pattern having a line width smaller than a space width. According to the photosensitive film and the photosensitive resin composition of the present embodiment, in evaluation described in Examples, for example, adhesiveness of 10 μm or less can be obtained. 
     According to the photosensitive film or the photosensitive resin composition of the present embodiment, the minimal time for removing an unexposed area can be reduced, and excellent developability can be obtained. 
     According to the photosensitive film and the photosensitive resin composition of the present embodiment, excellent sensitivity (before temporal change) with respect to an active light ray can be obtained. According to the photosensitive film and the photosensitive resin composition of the present embodiment, in evaluation described in Examples, for example, an exposure dose of 105 mJ/cm 2  or less can be obtained. 
     The photosensitive film and the photosensitive resin composition of the present embodiment have photo-curability and a cured product can be obtained by photo-curing this photosensitive film or the photosensitive resin composition. A cured product of the present embodiment is a cured product (photo-cured product) of the photosensitive film or the photosensitive resin composition of the present embodiment. The cured product of the present embodiment may have a patterned shape (cured product pattern), and may be a resist pattern. The shape of a cured product pattern that can be obtained by the photosensitive film and the photosensitive resin composition of the present embodiment is not particularly limited.

The thickness of each of the photosensitive film and the cured product of the present embodiment may be 19 μm or less from the viewpoint of easily obtaining excellent resolution and adhesiveness. From these viewpoints, the thickness of each of the photosensitive film and the cured product of the present embodiment may be 1 to 20 μm, 5 to 20 μm, or 15 to 20 μm. The thickness of each of the photosensitive film and the cured product may be an average thickness of ten places thereof. 
     In the photosensitive film and the photosensitive resin composition of the present embodiment, a wavelength at which photosensitivity is exhibited is not particularly limited. The photosensitive film and the photosensitive resin composition of the present embodiment may have, for example, photosensitivity with respect to light having a wavelength of 300 nm or more, 340 nm or more, 350 nm or more, 355 nm or more, 365 nm or more, 375 nm or more, 390 nm or more, 395 nm or more, or 405 nm or more.

In an exposure step described below, an active light ray having a peak within these wavelength ranges can be used. The photosensitive film and the photosensitive resin composition of the present embodiment can be used, for example, as a negative-type photosensitive film and photosensitive resin composition.

     &lt;Photosensitive Element&gt; 
     A photosensitive element of the present embodiment includes a support and a photosensitive resin layer disposed on the support, and the photosensitive resin layer is the photosensitive film of the present embodiment. The photosensitive element of the present embodiment may include a protective layer disposed on the photosensitive resin layer. The photosensitive element of the present embodiment may include a cushion layer, an adhesive layer, a light-absorbing layer, a gas barrier layer, or the like. The photosensitive element may be in a sheet form, or may be in the form of a photosensitive element roll being wound around a core into a roll. 
       FIG.  1    is a schematic cross-sectional view illustrating an example of a photosensitive element. As illustrated in  FIG.  1   , a photosensitive element 1 includes a support (support film) 2, a photosensitive resin layer (photosensitive film) 3 disposed on the support 2, and a protective layer (protective film) 4 disposed on the photosensitive resin layer 3. The photosensitive resin layer 3 is composed of the photosensitive resin composition of the present embodiment. 
     The photosensitive element 1 can be obtained, for example, by the following procedure. First, the photosensitive resin layer 3 is formed on the support 2. The photosensitive resin layer 3 can be formed, for example, by drying a coating layer formed by applying a photosensitive resin composition containing an organic solvent. Next, the protective layer 4 is disposed on the photosensitive resin layer 3. 
     Each of the support and the protective layer may be a polymer film having heat resistance and solvent resistance, and may be a polyester film (such as a polyethylene terephthalate film), a polyolefin film (such as a polyethylene film or a polypropylene film), a hydrocarbon-based polymer (excluding a polyolefin film), or the like. The type of the film constituting the protective layer and the type of the film constituting the support may be the same as or different from each other. 
     The thickness of the support may be 1 μm or more, 5 μm or more, 10 μm or more, or 15 μm or more, from the viewpoint of easily suppressing the damage of the support when the support is peeled off from the photosensitive resin layer. The thickness of the support may be 100 μm or less, 50 μm or less, 30 μm or less, or 20 μm or less, from the viewpoint of suitably performing exposure in the case of exposure through the support. 
     The thickness of the protective layer may be 1 μm or more, 5 μm or more, 10 μm or more, or 15 μm or more, from the viewpoint of easily suppressing the damage of the protective layer when the photosensitive resin layer and the support are laminated on the base material while the protective layer is peeled off. The thickness of the protective layer may be 100 μm or less, 50 μm or less, or 30 μm or less, from the viewpoint of easily improving productivity. 
     &lt;Method for Producing Laminate&gt; 
     A method for producing a laminate of the present embodiment includes a disposing step (photosensitive resin layer disposing step) of disposing a photosensitive resin layer on a base material (for example, substrate) by using the photosensitive film, the photosensitive element, or the photosensitive resin composition of the present embodiment, an exposure step of photo-curing (exposing) a part of the photosensitive resin layer, and a development step of removing at least a part of an uncured area (unexposed area) of the photosensitive resin layer to form a cured product pattern. A laminate of the present embodiment is obtained by the method for producing a laminate of the present embodiment, and may be a wiring board (for example, a printed circuit board). The laminate of the present embodiment may be an embodiment including a base material and a cured product pattern (cured product of the present embodiment) disposed on the base material. 
     The base material may have a recessed portion. The cross-sectional shape (the shape of the cross-section perpendicular to the lamination direction) of the recessed portion may be a circular shape (for example, a substantially true circle shape), a rectangular shape, a line shape (a straight line shape), or the like. The recessed portion of the base material may be a bottomed recessed portion. The diameter (for example, maximum diameter) or the depth (length in the lamination direction) of the recessed portion may be in the following ranges. The diameter of the recessed portion may be 10 μm or more, 30 μm or more, 50 μm or more, 80 μm or more, 100 μm or more, 120 μm or more, 150 μm or more, 180 μm or more, or 200 μm or more. The diameter of the recessed portion may be 500 μm or less, 400 μm or less, 300 μm or less, 250 μm or less, or 200 μm or less. From these viewpoints, the diameter of the recessed portion may be 10 to 500 μm. The depth of the recessed portion may be 1 μm or more, 3 μm or more, 5 μm or more, 6 μm or more, or 8 μm or more. The depth of the recessed portion may be 20 μm or less, 18 μm or less, 15 μm or less, 12 μm or less, 10 μm or less, or 8 μm or less. The depth of the recessed portion may be 1 to 20 μm. 
     In the disposing step, a photosensitive resin layer composed of the photosensitive resin composition of the present embodiment is disposed on abase material. For example, the photosensitive resin layer may be formed by removing the protective layer from the photosensitive element and then pressure-bonding the photosensitive resin layer of the photosensitive element to the base material while heating the photosensitive resin layer, and may be formed by applying the photosensitive resin composition onto the base material and drying the photosensitive resin composition. The method for producing a laminate of the present embodiment may be an embodiment in which the base material has a recessed portion having the above-described diameter (for example, a diameter of 500 μm or less) and at least a part of the photosensitive resin layer is disposed inside the recessed portion in the disposing step. 
     In the exposure step, a region other than a region of the photosensitive resin layer in which a mask is disposed may be exposed and photo-cured by irradiation with an active light ray in a state where the mask is disposed on the photosensitive resin layer, and a part of the photosensitive resin layer may be exposed and photo-cured by irradiation with an active light ray at a desired pattern by a direct writing exposure method such as an LDI exposure method or a DLP exposure method without using a mask. As the light source for the active light ray, an ultraviolet source or a visible light source may be used and examples thereof include a carbon arc lamp, a mercury vapor arc lamp, a high-pressure mercury lamp, a xenon lamp, a gas laser (such as an argon laser), a solid-state laser (such as a YAG laser), and a semiconductor laser. 
     The development method in the development step may be, for example, wet development or dry development. The wet development can be performed using a developing solution suitable for the photosensitive resin composition, for example, by methods such as a dip method, a paddle method, a spray method, brushing, slapping, scrubbing, and dipping while shaking. The developing solution is appropriately selected in accordance with the configuration of the photosensitive resin composition, and may be an alkaline developing solution or an organic solvent developing solution. 
     The alkaline developing solution may be aqueous solutions containing bases such as alkali hydroxides such as hydroxides of lithium, sodium, or potassium; alkali carbonates such as carbonates or bicarbonates of lithium, sodium, potassium, or ammonium; alkali metal phosphates such as potassium phosphate and sodium phosphate; alkali metal pyrophosphate such as sodium pyrophosphate and potassium pyrophosphate; borax; sodium metasilicate; tetramethylammonium hydroxide; ethanolamine; ethylenediamine; diethylene triamine; 2-amino-2-hydroxymethyl-1,3-propanediol; 1,3-diamino-2-propanol; and morpholine. 
     The organic solvent developing solution may contain organic solvents such as 1,1,1-trichloroethane, N-methylpyrrolidone, N,N-dimethylformamide, cyclohexanone, methyl isobutyl ketone, and γ-butyrolactone. 
     The method for producing a laminate of the present embodiment may include a metal layer formation step of forming a metal layer on at least a part of a portion of the base material in which a cured product pattern is not formed, after the development step. The laminate of the present embodiment may be an embodiment including a base material, a cured product pattern (the cured product of the present embodiment) disposed on the base material, and a metal layer disposed on at least a part of a portion in the base material in which the cured product pattern is not formed. 
     The metal layer in the metal layer formation step may be, for example, a metal copper layer. The metal layer can be formed, for example, by performing a plating treatment. The plating treatment may be one or both of an electrolytic plating treatment and a non-electrolytic plating treatment. 
     The method for producing a laminate of the present embodiment may include a step of further curing a resist pattern by heating at 60 to 250° C. or exposure at 0.2 to 10 J/cm 2  after the development step. 
     The method for producing a laminate of the present embodiment may include a step of removing the cured product pattern after the metal layer formation step. The cured product pattern can be removed, for example, using a strong alkaline aqueous solution by performing development such as a dipping method and a spraying method.

A solution (b) was prepared by dissolving 0.5 parts by mass of azobisisobutyronitrile in 50 parts by mass of a mixed liquid of 30 parts by mass of methyl cellosolve and 20 parts by mass of toluene. After charging a mixed liquid of methyl cellosolve and toluene (methyl cellosolve:toluene=45:38 (mass ratio)) in a flask equipped with a stirrer, a reflux condenser, a thermometer, a dropping funnel, and a nitrogen gas inlet tube, stirring was performed while blowing nitrogen gas into the flask, and the temperature was raised to 80° C. The solution (a) was added dropwise to the above-described flask over 4 hours at a constant dropwise addition rate, and then the solution in the flask was stirred at 80° C. for 2 hours. Next, the solution (b) was added dropwise to the above-described flask over 10 minutes at a constant dropwise addition rate, and then the solution in the flask was stirred at 80° C. for 3 hours. Further, the solution in the flask was heated to 95° C. over 1 hour and kept at 90° C. for 2 hours, stirring was then stopped, and the solution was cooled to room temperature (25° C.), thereby obtaining a solution of a binder polymer A1.

     The acid value of the binder polymer A1 was 176 mgKOH/g. The acid value was measured by the following procedure. First, the binder polymer A1 was weighed in an Erlenmeyer flask. Next, the binder polymer A1 was dissolved by addition of a mixed solvent (mass ratio: toluene/methanol=70/30), and then a phenolphthalein solution was added as an indicator thereto. Then, the acid value was obtained by performing a titration using a 0.1 mol/L (N/10) potassium hydroxide solution (alcohol solution). 
     The weight average molecular weight (Mw) of the binder polymer A1 was 35000, and the number average molecular weight (Mn) thereof was 16000.

     &lt;Production of Photosensitive Element&gt; 
     A polyethylene terephthalate film (manufactured by Toray Industries, Inc., trade name “FB-40”) having a thickness of 16 μm was prepared as the support. The above-described photosensitive resin composition was applied onto the support to have an uniform thickness and then sequentially dried with a hot air convection drier set at 70° C. and 110° C. to form a photosensitive resin layer (photosensitive film; average thickness of ten places after drying: 19 μm). A polyethylene film (manufactured by TAMAPOLY CO., LTD., trade name “NF-15”) as the protective layer was attached onto the photosensitive resin layer, thereby obtaining a photosensitive element including the support, the photosensitive resin layer, and the protective layer in this order. 
     &lt;Production of Laminate&gt; 
     A copper-clad laminate plate (substrate, manufactured by Showa Denko Materials Co., Ltd., trade name: MCL-E-67) including copper foils (thickness: 18 μm) disposed on both surfaces of a glass epoxy material was pickled, rinsed, and then dried with an air stream to obtain a base material. Next, this base material was heated to 80° C., and then the above-described photosensitive element was laminated so that the photosensitive resin layer was in contact with the copper surface while the protective layer was peeled off, thereby obtaining a laminate A including the base material (copper-clad laminate plate), the photosensitive resin layer, and the support in this order. The lamination was performed using a heat roll set at 110° C. at a pressure-bonding pressure of 0.4 MPa and at a roll speed of 1.5 m/min. 
     A copper-clad laminate plate (substrate, manufactured by Showa Denko Materials Co., Ltd., trade name: MCL-E-67) including copper foils (thickness: 18 μm) disposed on both surfaces of a glass epoxy material was pickled, rinsed, and then dried with an air stream to obtain a base material. Next, a circular hole (cross-sectional shape: substantially true circle) having a diameter of 200 μm and a depth of 8 μm was formed at 25 places (array: 5×5, shortest distance between adjacent circular holes: 2 cm) on this base material. Next, the above-described photosensitive element was laminated by the same procedure as in the laminate A with respect to the surface of this base material on which the circular holes were formed, thereby obtaining a laminate B including the base material (copper-clad laminate plate), the photosensitive resin layer, and the support in this order. 
     &lt;Evaluation&gt; 
     (Sensitivity Before Temporal Change) 
     After a 41-step tablet (manufactured by Showa Denko Materials Co., Ltd.) was placed on the support of the above-described laminate A, the photosensitive resin layer was exposed through the support at an exposure dose (irradiation energy dose) for 15 steps remaining on the 41-step tablet after the development by a direct writing exposure machine (manufactured by Via Mechanics, Ltd., trade name: DE-1UH) employing a blue-violet laser diode with a wavelength of 405 nm as the light source. The sensitivity (photosensitivity) was evaluated using the exposure dose (unit: mJ/cm 2 ) at this time. Results are shown in Table 1. A smaller exposure dose indicates more satisfactory sensitivity. 
     (Temporal Stability of Sensitivity) 
     The photosensitive elements were prepared and then stored at room temperature (25° C.) for 7 days and 14 days, thereby obtaining two types of the photosensitive elements for temporal stability of sensitivity. A laminate a1 was obtained by the same procedure as in the above-described laminate A using the photosensitive element stored for 7 days. A laminate a2 was obtained by the same procedure as in the above-described laminate A using the photosensitive element stored for 14 days. The exposure dose (irradiation energy dose) was acquired in the same manner as in the above-described evaluation of sensitivity before temporal change using the laminate a1 and the laminate a2, and a difference between the exposure dose of the laminate a1 and the exposure dose of the laminate a2 was obtained. A case where the ratio of the exposure dose difference with respect to the exposure dose of the laminate a1 is 5% or less was evaluated as “A”, and a case where the ratio thereof exceeds 5% was evaluated as “B”. Results are shown in Table 1. 
     (Minimum Developing Time) 
     The above-described laminate A was cut into a square shape (5 cm×5 cm) and then the support was peeled off, thereby obtaining a test specimen. Then, an unexposed photosensitive resin layer in the test specimen was spray-developed at a pressure of 0.15 MPa using a 1% by mass sodium carbonate aqueous solution set at 30° C., and the shortest time that allowed the removal of the unexposed photosensitive resin layer to be visually confirmed was obtained as a minimum developing time (MD). A full-cone type nozzle was used. The distance between the above-described test specimen and the nozzle tip was 6 cm and the test specimen was disposed in such a manner that the center of the test specimen would coincide with the center of the nozzle. Results are shown in Table 1. A shorter minimum developing time (unit: second) indicates more satisfactory developability. 
     (Resolution) 
     After a 41-step tablet (manufactured by Showa Denko Materials Co., Ltd.) was placed on the support of the above-described laminate A, exposure (drawing) was performed for the photosensitive resin layer through the support without Offset at an exposure dose (irradiation energy dose) for 15 steps remaining on the 41-step tablet after the development by a direct writing exposure machine (manufactured by Via Mechanics, Ltd., trade name: DE-1UH) employing a blue-violet laser diode with a wavelength of 405 nm as the light source using a drawing pattern with a line width (L)/space width (S) (hereinafter, referred to as “L/S”) of 3x/x (x=1 to 20, unit: μm, interval: 1 μm). Within 3 minutes after the exposure, post-exposure-bake (PEB) was performed using a heating oven under conditions of 80° C. and 30 seconds. 
     After the exposure, the support was peeled off from the laminate A to expose the photosensitive resin layer, and unexposed areas were removed by spraying a 1% by mass sodium carbonate aqueous solution at 30° C. for time twice the above-described minimum developing time. After the development, the resolution was evaluated by the minimum value (unit: μm) among the space width values of resist patterns in which space areas (unexposed areas) were removed without residues and line areas (exposed areas) were formed without meandering and defecting. Results are shown in Table 1. A smaller numerical value indicates more satisfactory resolution. 
     (Adhesiveness) 
     After a 41-step tablet (manufactured by Showa Denko Materials Co., Ltd.) was placed on the support of the above-described laminate A, exposure (drawing) was performed for the photosensitive resin layer through the support without Offset at an exposure dose (irradiation energy dose) for 15 steps remaining on the 41-step tablet after the development by a direct writing exposure machine (manufactured by Via Mechanics, Ltd., trade name: DE-1UH) employing a blue-violet laser diode with a wavelength of 405 nm as the light source using a drawing pattern with an L/S of x/3x (x=1 to 20, unit: μm, interval: 1 μm). Within 3 minutes after the exposure, post-exposure-bake (PEB) was performed using a heating oven under conditions of 80° C. and 30 seconds. 
     After the exposure, the support was peeled off from the laminate A to expose the photosensitive resin layer, and unexposed areas were removed by spraying a 1% by mass sodium carbonate aqueous solution at 30° C. for time twice the above-described minimum developing time. After the development, the adhesiveness was evaluated by the minimum value (unit: μm) among the line width values of resist patterns in which space areas (unexposed areas) were removed without residues and line areas (exposed areas) were formed without meandering and defecting. Results are shown in Table 1. A smaller numerical value indicates more satisfactory adhesiveness. 
     (Followability) 
     Circular holes at ten places of the laminate B from the support side were observed using an optical microscope (KEYENCE CORPORATION, VK-8500). The area (Air void size, unit: μm 2 ) of air bubbles generated between the circular holes and the cured product of the photosensitive resin layer was measured, and an average value of the circular holes at ten places was calculated. Results are shown in Table 1. A smaller area of air bubbles indicates excellent followability (circular hole followability).
