Description

  The present invention relates to a copy form using carbonless paper, more specifically, a carbonless top paper provided with a color former layer on the back surface of the substrate, a developer layer provided on the surface of the substrate, and The present invention relates to a copy form and a method for manufacturing the same, in which a carbonless middle paper provided with a color former layer on the back surface is superposed to allow a color developer layer in a predetermined area to be colored.

  Conventionally, in addition to this paper, copy forms using carbonless paper have been used for various forms that require a copy. As a general copying mechanism, carbonless paper is made by applying a pressure from the opposite side of the capsule coating surface, with the substrate coated with the developer facing the surface coated with the encapsulated dye. When the capsule is broken, the electron-donating leuco dye in the capsule reacts with the electron-accepting developer to develop a color.

  There are generally three types of carbonless paper, upper paper (top paper), middle paper (middle paper), and lower paper (bottom paper), and these are used in combination. (See Patent Document 1) The upper paper has a color former layer provided on the lower surface of the base material, and the middle paper has a developer layer provided on the upper surface of the base material and a color former layer provided on the lower surface of the base material. The lower paper is provided with a developer layer on the upper surface of the substrate. In general, in a roll-shaped medium, the color former layer and the developer layer are in contact with each other, so that when the winding pressure is high or when external pressure is applied, the capsule is broken and the electron-donating leuco dye and There was a problem that the electron-accepting developer surface reacted and developed color.

  In recent years, products have been manufactured through various processes due to the complexity of the products. In each process, there is a problem due to coloring of the electron-accepting developer layer in the winding form described above. It has become apparent. For example, when a pattern is formed on the color former layer by a contact printing method, the capsule is broken, and when it is wound by delivery, the electron donating leuco dye reacts with the electron accepting color developer layer to form a color stain. .

  Conventionally, as a technology that does not cause color development on carbonless paper, an electron-donating leuco dye is contacted by printing and reacting an electron-donating ink called a desensitizer on the electron-accepting developer layer. Techniques for preventing reaction are known. However, in this case, once the desensitizer is printed, it does not return to its original state, so it is not desired to develop the color only within the process, but as a product, it cannot be used for the part that is desired to be developed. there were.

In addition, in copy forms using carbonless paper, the developer on the lower paper is selectively scraped off by laser irradiation for the purpose of preventing counterfeiting of information copied on the lower paper, etc. Patent Document 3 discloses that the impossible portion is formed. In such a method of scraping off the developer layer by laser irradiation, once the developer layer is scraped off, it does not return to the original color developing state. It cannot be adopted as a measure to stain the layer by coloring.

Each layer constituting the copy form of the present invention will be described in detail below.
(Base material)
As the base materials 6, 8, 12, and 14 of carbonless carbon top paper, carbonless middle paper, and carbonless bottom paper, a developer layer is retained, and a color former layer and a sealing layer are retained. However, there is no particular limitation as long as the handling of the copy form can be maintained. For example, fine paper, art paper, coated paper, cast coated paper, synthetic resin or emulsion impregnated paper, synthetic rubber latex impregnated paper, synthetic resin internal paper, paper such as cellulose fiber paper, polyolefin (polyethylene, polypropylene, etc.), Plastic sheets of various synthetic resins such as polystyrene, polycarbonate, polyethylene terephthalate, polyvinyl chloride, polymethacrylate, etc., white opaque films formed by adding white pigments and fillers to these synthetic resins, or fine inside the substrate A film (so-called synthetic paper) having voids (microvoids) can be used as a substrate.

  In addition, paper suitable for the recording method is used on the surface of the carbonless top paper base material for printing by dot impact recording or handwriting. For example, paper that is easy to fix the ink for dot impact recording, paper that has writing properties, and the like can be mentioned. The thickness of the substrate is usually about 3 to 300 μm, and in the present invention, it is preferable to use a substrate having a thickness of about 20 to 175 μm in consideration of handling suitability, laser irradiation suitability, and the like.

(Developer layer)
A developer layer is formed on the surface of each base material of carbonless middle paper or carbon bottom paper, and the developer layer is a conventionally used electron-accepting phenolic hydroxyl group. Alternatively, a binder component such as starch or polyvinyl alcohol is added to a developer such as an organic compound having an alcoholic hydroxyl group, and if necessary, a solvent is added, and the prepared coating liquid is air knife coater, blade coater, rod It can be formed by coating on a substrate with a normal coating apparatus such as a blade coater, roll coater, bar coater, curtain coater or the like. The coating amount of the developer layer, from 1 to 20 g / m ² on a dry solids, preferably from 2 to 10 g / m ^2. Before applying the coating solution for the developer layer, the surface of the applied developer layer is smoothed by passing the paper through a super calender or soft nip calender, etc., and pressurizing and smoothing the substrate surface. Therefore, the color density by the color former becomes uniform, which is preferable.

(Coloring agent layer)
A color former layer is formed on the back surface of each substrate of carbonless paper, carbonless top paper, and carbonless middle paper. As the color former layer, for example, in the microcapsule, the developer described above and A color former that develops color when contacted is dissolved in oil, and the encapsulated microcapsules can be dispersed in a binder component to form. The color former used in the present invention is a pressure-sensitive color former that develops color when the capsule is broken by pressure and the color former oil comes out of the microcapsule and moves to the developer.

  As the color former, an electron-donating leuco dye is used, and examples thereof include blue color formers such as CVL (crystal violet lactone) and BLMB (benzoyl leucomethylene blue), and black color formers such as fluoran compounds. It is done. Examples of the oil include alkylnaphthalene, diarylethane, alkylated biphenyl, hydrogenated terphenyl and the like. Moreover, a pressure-sensitive color former can be used individually by 1 type or in combination of 2 or more types. Color developing agent-encapsulated microcapsules produced by an encapsulation method such as an interfacial polymerization method, an in situ method, a phase separation method, a coacervation method, a binder component such as polyvinyl alcohol, starch, natural rubber latex, Furthermore, a coating liquid obtained by mixing a capsule protective agent such as starch powder and talc, a solvent and the like, if necessary, is formed on a substrate.

The color former layer can be formed on a substrate by applying a coating liquid containing the above-described materials in the same manner as the coating conditions for the developer layer. The coating amount of the color former layer, 1.5~10g / m ² on a dry solids, preferably 2-5 g / m ^2. Before applying the color former layer coating solution, it is possible to pass the paper through a super calender, a soft nip calender, or the like to finish the surface of the base material under pressure and smoothing.

(Sealing layer)
It is essential to provide a sealing layer on the developer layer of the carbonless middle paper in the copy form of the present invention. When the carbonless middle paper is in the winding state during the manufacturing process, when the winding pressure is strong or when external pressure is applied, the sealing layer is a color former that is dissolved in oil by breaking the capsule of the color former layer However, it is prevented from penetrating and transferring to the developer layer and reacting with the developer to cause color development. Therefore, if the sealing layer is a film having a uniform predetermined thickness so that the color former dissolved in the oil does not penetrate and migrate into the developer layer, the material constituting the sealing layer is: It is not limited.

For example, it is composed of a material mainly composed of a water-soluble polymer such as polyvinyl alcohol or starch, or a thermosetting resin, an electron beam curable resin, or an ultraviolet curable resin, which is heated or irradiated with an electron beam. Can be cured to form a sealing layer. Among these, it is easy to put to practical use and it is preferable to use a sealing layer mainly composed of an ultraviolet curable resin. The sealing layer has a dry coating amount of about ² to ²⁰ g / m ² on the developer layer by a conventionally known method such as gravure direct coating, gravure reverse coating, knife coating, air coating, roll coating, etc. Can be formed.

(Print layer)
The printing layers 50 and 51 of the present invention are formed on the sealing layer, and the shape and color are not limited. Examples of the shape include arbitrary characters and images such as various background patterns and patterns. The copy form of the present invention has a cutting portion by laser irradiation in the sealing layer. In order to increase the positional accuracy of the cutting portion, the printed layer is used as a detection mark, the mark is read, and the sealing is performed. It is preferable that a predetermined region of the layer is aligned and irradiated with a laser to scrape off the filler layer to form a cut portion.

  The form of the detection mark, such as the shape and color, is not limited as long as it can be detected by a detector. Examples of the shape include a quadrangular shape, a round shape, a barcode, a crosshair, and the like. FIG. 3 is a plan view showing one embodiment of the detection mark. The four detection marks 52, 53, 54, and 55 can be read, and the cut portions 18 in the sealing layer can be formed with these marks as four corners. The color of the detection mark only needs to be detectable by a detector. For example, in the case of a light transmission type detector, examples include silver and black having high concealment properties, and in the case of a light reflection type detector, light reflectivity. High metallic luster color tone or black.

  The detector 46 detects the position of the detection mark by reflecting the light emitted from the light emitting element by a detection mark which is a printing layer provided on the carbonless middle paper and detecting the reflected light by the light receiving element. Is done. Such a detection mark is detected by a light reflection type sensor, but is not limited thereto. Light is emitted from the light emitting element on one side of the carbonless middle paper to the detection mark, and the light It is also possible to use a transmissive sensor that detects the transmitted light with a light receiving element having the other side of the carbonless middle paper.

  The above printing layer can be used for detecting characters, background patterns, patterns, etc., arbitrary characters and images, intaglio printing such as gravure printing, lithographic printing such as offset method, letterpress printing, screen printing, ink jet printing, etc. It can be formed by printing on the middle paper sealing layer.

(Manufacturing method of copy forms)
Below, the manufacturing method of the copy form of this invention is demonstrated. The method for producing a copy form according to the present invention comprises a carbon layer in which a developer layer, a sealing layer, and a printing layer are provided in this order on the surface of a second substrate, and a color former layer is provided on the back surface of the second substrate The middle paper and the carbonless top paper provided with the color former layer on the back of the first substrate are overlapped so that the color former layer of the carbonless top paper and the developer layer of the carbonless middle paper are in contact with each other. In the method for producing a copy form, the printed layer is read as a detection mark, the predetermined area of the sealing layer is aligned, the laser is irradiated, and the sealing layer is scraped off. The colorant layer and the developer layer corresponding to the shaved area are overlapped so as to allow color development. That is, when the carbonless top paper and the carbonless middle paper are overlapped, the carbonless middle paper having the printing layer / sealing layer / developer layer / second base material / coloring agent layer lamination condition is sealed. After irradiating the layer with laser to scrape off the filler layer, the color former layer (in the carbonless top paper) corresponding to the shaved area and the developer layer (of the filler layer in the carbonless middle paper) It is characterized in that it is superposed so that it can be colored by reaction with the developer layer exposed at the cutting part).

  The means for cutting the sealing layer by laser irradiation in the present invention, that is, the laser processing means uses YAG laser, carbon dioxide laser, ruby laser or the like as the laser beam. Since it can condense, finer processing is possible and it is preferably used. In the present invention, the terms laser irradiation and laser light irradiation are used, but “laser” and “laser light” have the same meaning, and there is no difference between the terms.

  An example of the laser processing means used in the present invention will be described. First, the laser beam is condensed by a lens and irradiated to the surface of the sealing layer of the carbonless middle paper. At that time, by changing the laser light irradiation time or the laser output value (laser light intensity × irradiation area), the depth to be cut, that is, the depth to be cut can be adjusted. In the present invention, the sealing layer is scraped off by laser irradiation so that the cutting layer has no sealing layer and the developer layer remains as shown in FIGS. Therefore, the depth to be scraped is made to coincide with the thickness of the sealing layer. The intensity of the laser light can be adjusted, for example, from 100 W to 600 W, and the irradiation area can be 50 to 800 μm in diameter. Thus, the sealing layer can be cut easily, with high accuracy, good reproducibility, and non-contact with the processed portion.

  As an example of changing the laser irradiation area, the irradiation area can be increased as follows. A laser light source 31, a lens 33 arranged coaxially with the light beam of the laser light 32 emitted from the laser light source 31, and the optical axis 34 of the lens 33 can be obtained using an apparatus as shown in FIG. The first reflector 35a that reflects the laser beam 32 disposed in the direction away from the optical axis 34 and the laser beam 32 that is reflected by the first reflector 35a are applied to the sealing layer surface 36 of the carbonless middle paper. It is comprised from the optical path conversion part 35 comprised from the 2nd reflector 35b arrange | positioned so.

  The laser light 32 emitted from the laser light source 31 is collected by the lens 33 to concentrate the energy density, reflected by the first reflector 35a and the second reflector 35b, and the position of the focal point 40 of the lens 33. , The laser beam 32 becomes the thinnest, spreads again, and is irradiated onto the sealing layer surface 36 that is the irradiation surface.

  The optical path changing unit 35 composed of the first reflector 35a and the second reflector 35b rotates around the optical axis 34 of the lens 33 as a rotation axis. Thereby, the laser beam 32 irradiated on the irradiation surface 36 is scanned around the optical axis 34, and the irradiation area of the irradiation surface of the laser beam is expanded, and as a result, the irradiation area can be increased.

  Further, the waste of the sealing layer cut by the laser irradiation can be sucked and discharged outside using a duct connected to a blower device. In this way, the components of the cut sealing layer do not transfer and adhere to the surface of carbonless middle paper or the like, and further, no stress is applied to the processed portion, and burrs and distortions do not occur. The laser processing means preferably uses a laser beam in an infrared region of about 0.9 to 11 μm, and the portion irradiated with the laser light is heated. The portion irradiated with the laser light is locally heated and cut by blowing off the portion in the liquid phase in the state exceeding the melting point of the portion, and laser processing is performed.

  As shown in FIG. 6, the laser processing apparatus includes a laser oscillator 20 including a laser head 21, a processing optical system (lens) 22, and a laser power source 23, and a carbonless middle paper that is a workpiece. 3 and 5, an XY table 24 that can move in the horizontal plane (in the XY plane), a Z table 25 that moves the laser head 21 and the processing optical system (lens) 22 in the vertical direction (Z-axis direction), and an XY table. The laser processing apparatus 30 includes a main controller 26 that automatically or manually controls the movement operation in the horizontal plane of 24, the movement operation in the vertical direction of the Z table 25, and the oscillation operation of the laser oscillator 20.

  By controlling the main controller of the laser processing apparatus as described above and the detection mark of the printed layer, such as by sending a signal read by the detector to the main controller of the laser processing apparatus, etc. Cutting portions 18 and 19 as shown in FIGS. 1 to 3 can be formed by changing the cutting amount of the sealing layer and the cutting position. In order to change the cutting position, for example, the position of the optical path changing unit 35 of the apparatus described above may be adjusted. Although not shown in FIG. 6, a printing layer as a detection mark is provided on the carbonless middle paper, and the detection mark is used as a start detection signal or an end detection signal for laser irradiation, and the processing position is further moved. Therefore, it is preferable to use a means for controlling the conveyance of the carbonless middle paper in combination.

  In particular, when the carbonless middle paper is not a single sheet but a long continuous sheet, when the continuous sheet is continuously irradiated with a laser, a carbon steel middle paper under the laser head is installed on a horizontal table. This is because the processed carbon-free middle paper can be transported and the next carbon-free middle paper to be processed can be moved to the processing position on the horizontal table and prepared.
