Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a three-fold form with partial copying function consisting of pressure-sensitive copying sheet.
[0002]
[Prior art]
A conventional pressure-sensitive copying sheet is usually a pressure-sensitive copying upper sheet (hereinafter abbreviated as an upper sheet) formed by microencapsulating an electron-donating color former solution and applying it to the entire back surface of the sheet substrate. Correspondingly, a pressure-sensitive copying lower sheet (hereinafter abbreviated as a lower sheet) obtained by applying a coating material in which an electron-accepting developer is dispersed in water together with a binder on the entire surface of the sheet base material. ) And a sheet for copying inside (hereinafter abbreviated as a medium sheet) in which a developer and a color former microcapsule are respectively applied to the entire front and back surfaces of the sheet base material. It is often used in multi-part pressure-sensitive copying sheet sets. Conventionally, in such a standard pressure-sensitive copying sheet, when it is desired to partially prevent copying (or to make a partial copying), generally, the color of the lower sheet or the middle sheet is generally developed. A desensitizing ink layer that inhibits color development was applied to the part of the agent layer where it was desired to prevent copying.
[0003]
On the other hand, special printing inks containing developer and color former microcapsules have recently been put to practical use, and this printing ink is directly applied to a desired portion of a sheet substrate surface made of normal paper. A partial-copy pressure-sensitive copying sheet provided with a layer can be obtained. This pressure-sensitive copy sheet is subjected to various processes such as folding lines, tear lines, adhesive coating, or separate sheet and film attachment, and when the sheet is further folded or stacked, partial copying is performed. Forms, envelopes, postcards and the like having functions are configured.
[0004]
[Problems to be solved by the invention]
However, in the pressure-sensitive copying sheet for partial copying using the former standard pressure-sensitive copying sheet, the color former microcapsule layer corresponding to the desensitizing ink layer is not used at all and is wasted. When the area of the prevention portion is large, a cost problem occurs. Further, since the color former microcapsule layer is applied to the entire surface of the sheet, rubbing stains are likely to occur, or the printability on the color former microcapsule layer face is very poor. Therefore, the suitability of processing such a standard pressure-sensitive copying sheet into a complicated structure of folding, cut-up forms, envelopes, postcards, etc. has been very poor.
[0005]
On the other hand, in the pressure-sensitive copying sheet for partial copying obtained by applying special printing inks such as developer ink and color developer microcapsule ink, any copying part can be set, so there is a problem with standard ones Is unlikely to occur. However, currently developed developer inks require special equipment for the coating and drying process, resulting in poor productivity, and are mainly water-based inks. There was an inconvenience that wrinkles were generated. Further, the obtained developer layer has a problem in that it is inferior in color development performance such as color density, color development speed and deterioration with time as compared with the developer layer in a standard pressure-sensitive copying sheet.
[0006]
Therefore, in the present invention, it is excellent in productivity, processability and cost, solves problems such as rubbing dirt and color development ability, and further prevents penetration of the color developer microcapsule-containing ink into the developer layer. Another object of the present invention is to provide a tri-fold form made of a pressure-sensitive copying sheet that prevents self-coloring (backside copy) due to pressing of printing or the like at the time of copying.
[0007]
[Means for Solving the Problems]
In order to achieve this object, the present inventors put the sheet on a predetermined portion of the developer layer of a pressure-sensitive copying sheet having a developer layer on the surface of the sheet substrate, for example, a standard lower sheet. A pressure-sensitive copying sheet has been conceived in which a partial color former microcapsule ink layer is provided via a desensitizing ink layer in accordance with the configuration of a folded form to be created.
That is, the present onset bright consists pressure-sensitive copying sheets forming the developer layer on the back surface total surface of the sheet substrate which is partitioned into a form on a paper strip and form lower paper and form in paper with perforated lines for folding, The sheet medium sheet piece is folded from the folding machine line so that the sheet substrate back surface side of the form medium sheet piece corresponds to the sheet substrate back surface side of the form lower sheet piece, and the sheet substrate surface side of the sheet medium sheet piece And a three-fold form in which the form upper paper piece is folded from a folding machine line so that the back side of the sheet base material in the form upper paper piece corresponds to an item entry field on the sheet base material surface in the form lower paper piece is provided, the surface of the desensitizing ink layer on the item entry field opposite surface to become part of in the developer layer of the backsheet substrate is provided in該帳slip under a piece of paper, and said desensitizing ink layer coloring agent micro capsule to And Le layer is provided, wherein the color former microcapsule layer of the form under the paper strip, the form in contact against the said developer layer of the backsheet substrate in paper, the form of a sheet substrate surface in the form of paper A color former microcapsule layer is provided in a portion corresponding to the item entry column of the paper piece, and the color former microcapsule layer of the paper piece in the form is opposed to the developer layer on the back side of the sheet base material in the paper upper piece of the form. It is a tri-fold form characterized by touching .
[0008]
To explain the basic structure of a pressure-sensitive copying sheet 1 with reference to FIG. 1, a pressure-sensitive copying sheet comprising subjecting a developer layer D on the sheet substrate 2 top surface 3, of the developer layer D A desensitizing ink layer B is provided on a predetermined portion of the surface 4, and a color former microcapsule ink layer C is provided on the surface 5 of the desensitizing ink layer B.
[0009]
Sheet over preparative substrate 2 of pressure-sensitive copying sheet comprising subjecting a developer layer D on the surface 3 may those subjected to color developing agent layer on the base sheet over the entire surface using a dedicated coater, for example the Select a predetermined sheet base material from thick paper, synthetic paper, synthetic resin film, etc. according to the material, paper thickness, basis weight, etc. of the folded form composed of pressure-sensitive copying sheets, and the same as in the standard lower sheet It is preferable to apply a coating material obtained by dispersing a conventionally known developer such as phenol resin, acid clay, bentonite, etc. in water together with a binder over the entire surface or substantially the entire surface of the sheet base material. In actual production, it is most preferable to use a fixed sheet for lowering in terms of productivity, coloring performance, cost and the like.
[0010]
The desensitizing ink constituting the desensitizing ink layer B is not limited in any way, and a vehicle in which a conventionally known desensitizing agent such as a cationic surfactant, polyol, amines or the like is dissolved in an alcohol-soluble resin in an alcohol solvent. It may be dispersed together with a pigment such as titanium white or barium sulfate. This desensitizing ink layer B prevents the penetration of the color developing agent microcapsule-containing ink into the developer layer D when the color developing agent microcapsule layer C described later is printed, and is capable of printing, etc. It has a barrier layer function of preventing self-coloring (back surface exposure) due to pressing. Therefore, the desensitizing ink layer is preferably provided with a slightly larger area than the color former microcapsule layer so that the barrier function is not impaired.
[0011]
The color former microcapsule ink constituting the color former microcapsule layer C is not particularly limited as long as the color former microcapsules are dispersed in the printing ink vehicle. However, it is most preferable to use a microcapsule-containing oil-based ink manufacturing technique (Japanese Patent Laid-Open No. 7-216273) developed by the present inventors. This is achieved by adding a substance having a lipophilic group and a hydrophilic group, such as lower alcohol, to a color former microcapsule solution produced in an aqueous system, and substituting the oil system in a dispersed state using a vacuum dehydration method under a predetermined condition. The capsules have good dispersibility, the abundance of secondary particles due to aggregation is extremely low, and are excellent in printability and color development performance.
