Abstract

PURPOSE:To enable to easily make a stencil for desired patterns such as characters and figures with high resolution, by providing a covering film of a specified water-insoluble polymer on a porous base. CONSTITUTION:One of polyesters, polyethers and polyamides having tertiary amino groups, tertiary aminoalkyl acrylate polymers, homopolymers and copolymers of vinylpyridine and the like is used as a water-insoluble polymer having tertiary amino groups to produce a covering film on the porous base. A solution of a water-soluble acid is used as a stencil-making liquid. Particularly when the stencil is applied to household or infant use or the like, an organic acid, particularly, citric acid, tartaric acid or the like, is used. When the stencil-making liquid is applied to the polymer, a reaction product soluble in water or a water-soluble liquid is formed only at the part where the stencil-making liquid is applied. Accordingly, when a pattern is drawn in the stencil-making liquid with a sharp-pointed pen or the like, perforations comprising fine lines can be obtained, and when a pattern is drawn in the liquid with a brush-like pen, perforations rich in the feeling of a brush drawing can be obtained with high resolution.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a stencil printing plate easily made by handwriting etc.
The present invention relates to a method for making the stencil printing plate, and a stencil printing method using the stencil printing plate that is performed after these stencil printing steps.

Many methods for obtaining printed matter have been known, and simple printing methods include a letterpress printing method and a stencil printing method.

However, both of them have drawbacks such as making letterpress and stencil printing is troublesome, and it is difficult to make a pattern according to your preference.If you print using these plates, you will end up not getting the desired pattern. It was not possible to easily obtain printed matter. Therefore 9
The present invention improves these drawbacks by developing a particularly novel plate-making material for stencil printing.

Traditionally, the methods for making stencils include writing on mimeograph paper coated with wax on washi paper with an iron pen, ballpoint pen, etc., then mechanically removing the wax and perforating it, or applying a solvent, dissolving it, and removing it to perforate it. There is a plate-making method to do this. With the former method, it is difficult to produce large lines on the mimeograph paper, regardless of the thickness of the tip of the pen, and it is not possible to perforate beautiful cursive writing like a calligraphy brush or cursive writing with a large area, and the resolution is also poor. Met. In the latter method, the wax melts at a slow rate, resulting in areas that cannot be completely perforated if the solvent is applied at normal writing speeds.

In addition, since the solvents used for drilling are harmful.

There were also problems in handling. Also, after drawing on a mesh support with a drawing material such as crayon.

A plate-making method (To-7
There is a method called E&Hibiki Glue Method), but the plate-making process is complicated and troublesome.

Since it uses a solvent, there were many problems in handling.

Therefore, the present invention uses a stencil printing original plate and a plate-making liquid to easily produce designs such as characters and patterns in thin or thick lines by handwriting or stamping, without any problem in handling. It is perforated. Furthermore, it is an object of the present invention to provide a stencil printing method which is characterized in that clear printed matter can be obtained when stencil printing is performed using a stencil-made stencil printing plate and stencil printing ink.

9. Stencil printing as used in the present invention not only means obtaining visible prints with colored inks using a stencil printing plate, but also includes printing with colorless dye intermediate inks, glue inks, etc. .

Ink that changes color depending on temperature can also be used as appropriate.

It also includes textile printing.

The present inventor continued to study based on the knowledge that a water-insoluble tertiary amine group-containing polymer reacts with an acid to produce a water-soluble reaction product, and found that the polymer is extremely stable until it comes into contact with an acid. They have discovered that a stencil printing plate that can achieve the above objective can only be obtained by using a combination of a stencil printing original plate and a plate-making liquid that is a water-soluble acid solution, and further, when performing stencil printing using this stencil printing plate. For the first time, he discovered a printing method that was simple, yet produced printed matter with beautiful designs that people liked and understood.

The invention has been completed.

In other words, the first invention of the present invention has a third aspect of the present invention.
This is a stencil printing plate comprising a shielding film made of a water-insoluble polymer having a class amine group and a pattern portion in which the shielding film is not present. The second aspect of the present invention is to form a shielding film of a water-insoluble polymer having a tertiary amine group on a porous support, and to draw a pattern on a stencil printing original plate using a plate-making liquid consisting of a water-soluble acid solution. This is a method for making a stencil printing plate, in which a shielding film is treated with water or a water-soluble liquid to form a stencil printing plate. The third aspect of the present invention is to draw a pattern on a stencil printing original plate in which a shielding film of a water-insoluble polymer having a tertiary amino group is formed on a porous support using a plate-making liquid consisting of a water-soluble acid solution. This is a stencil printing method in which a shielding film is treated with water or a water-soluble liquid, the treated portion is removed with water or a water-soluble liquid to form a stencil printing plate, and printing is then carried out by spreading printing ink on this stencil printing plate. .

In the stencil printing original plate before plate making of the stencil printing plate of the present invention, the third
As water-insoluble polymers having tertiary amine groups, polyesters, polyethers, polyamides, and tertiary aminoalkyl acrylate polymers having tertiary amine groups, and vinyl pyridine homopolymers and copolymers are used. A shielding film is formed on the transparent support.

These polymers include many compounds, such as esters of diols and dicarboxylic acids containing tertiary amine groups, diol polycondensates containing tertiary amine groups, and diamines containing tertiary amine groups. Polycondensates of and dicarboxylic acids, homopolymers of tertiary aminoalkyl acrylates, copolymers of tertiary aminoalgyl acrylates and monoethylenic monomers such as acrylic monomers and/or styrene monomers, 2-vinylpyridine or 4-vinyl Examples include homopolymers of pyridine, tonocopolymers of 4-vinyl pyridine and/or 2-pyridine and monoethylenically monomers, and the like. These polymers are water insoluble;
itself is stable.

As the porous support on which the polymer shielding film is formed, Japanese paper, nylon cloth, Tetoron cloth, nonwoven fabric, and other porous materials can be used. Further, the thickness of the support is preferably about 20 to 150μ, and the aperture ratio is preferably about 2.
It is 5 to 60 inches.

Supplementary Note: As a method for creating a stencil printing original plate by forming a shielding film on a porous support using a polymer, a solution in which the polymer is dissolved may be applied directly to the support and dried, or a solution containing the polymer may be directly applied to the support and dried. The body may be soaked and then dried, or a film of the polymer may be formed and the film may be affixed to a support. The thickness of the polymer deposited is preferably as thin as possible within a range that does not impair the durability of the stencil printing plate during printing, and the deposit amount is preferably 5 to 2'Of/m''.

Examples of solvents that dissolve the polymer include aromatic hydrocarbons such as benzene, toluene, and quinolene, ketone solvents such as methyl ethyl ketone and acetone, alcohol solvents such as methanol and ethanol, ether solvents such as ether and tetrahydroxyfuran, and acetic acid. Ester solvents such as ethyl and halogenated hydrocarbons such as trichloroethylene can be used.

In the present invention, a water-soluble acid solution is used as the plate-making liquid.

Examples of the solvent include water that dissolves acids, alcohol polyols, polyol ethers, and the like, and each bath agent may be used in combination.

The acid in the acid solution reacts with the polymer to form a water-soluble reaction product. The water-soluble acid used has a dissociation constant of 1.
0x10' or more is better.

For example, inorganic acids such as hydrochloric acid, sulfuric acid, phosphoric acid, and formic acid.

Acetic acid, propionic acid, chloric acid, dichloroacetic acid.

Trichloroacetic acid, glycolic acid, milk acid, oxalic acid, malonic acid, succinic acid, fumaric acid, maleic acid, malic acid,
There are organic acids such as tartaric acid and citric acid.

The present invention is characterized by the use of these water-soluble acid solutions, especially from the viewpoint of handling when used for home use or for infants.

It is optimal to use organic acids, especially citric acid and tartaric acid.

When applying plate-making liquid to the stencil printing original plate.

In order to uniformly apply the plate-making liquid to the surface of the polymer, it is preferable to add a surfactant to the plate-making liquid. Also, to make the traces of the plate-making liquid placed on the stencil printing original plate clearly visible.

It is preferred to have some amount of dye dissolved.

The plate making liquid is that! , or use it to fill a marker pen such as a felt pen or brush pen with a writing instrument for handwriting or filling in areas on the stencil printing original plate, or use a convex or concave stamp to write on the stencil printing original plate. It is used by filling a stamp pad etc. as a plate-making liquid impregnated body when stamping. At this time, it is preferable to add a wetting agent such as glycols in order to ensure that the plate-making liquid sufficiently wets the pen body or the impregnated body and to prevent drying after filling. By using a combination of a stencil printing original plate and a plate-making liquid, you can quickly and easily create a stencil printing plate with desired characters, patterns, and other designs.

First, a method for making a plate with good resolution will be described in detail.

When a plate-making liquid is applied to the polymer adhered to the stencil printing original plate, the polymer and the acid in the plate-making liquid rapidly react only in the attached portions, producing a reaction product that is soluble in water or a water-soluble liquid. The water-soluble liquid used in the present invention is a water-soluble liquid containing water and/or a polyol, and a surfactant.

Examples include aqueous solutions containing moisture absorbents, water-soluble resins, water-soluble glues containing polymer emulsions, and water-soluble printing inks. Therefore, brushes and markings are made by directly copying the printing fluid onto the original stencil printing plate using a pen.

Or by copying with a marker pen such as a felt pen or calligraphy pen filled with plate-making liquid, or by stamping with a porous stamp filled with plate-making liquid, or by making a convex or concave stamp from a stamp band filled with plate-making liquid. When a liquid is applied and a stamp is applied, only the area of the stencil printing original plate to which the plate-making liquid has been applied quickly becomes soluble in water or a water-soluble liquid. Next, immerse this stencil printing plate in water for a few seconds, or
Alternatively, only the area of the stencil printing plate that has become soluble in water or water-soluble liquid by water treatment such as rubbing lightly with a water-containing sponge or absorbent cotton, etc., is dissolved in water and perforated, and then dried and resolved. A desired stencil printing plate with good properties can be obtained. Similar results can be obtained by treating with a mixture of water and polyols instead of water treatment. If you copy the plate-making fluid with a pen with a thin tip, you will get perforations with thin lines, and if you copy with a brush-like pen, you will get perforations that feel like a brush. Perforations can be obtained with good resolution.

Next, a printing method for easily producing desired beautiful printed matter using the stencil printing plate and stencil printing ink obtained as described above will be specifically described.

Any type of stencil printing ink can be used as the printing ink, as long as it does not attack the polymer barrier film, such as oil-based, water-based, or emulsion-based stencil printing ink. Ink can be used as appropriate. Place these printing inks on a stencil printing plate, place printing paper underneath, and press the printing ink on the stencil printing plate while squeezing it with a squeegee, or simply place a flat plate and press it to create a clear print on the printing paper. can be obtained. In other words, the printing method is the conventional ski deer method and roll suppression method.

Although the press method and any other method can be used, the press method is optimal in terms of simplicity.

When using a water-soluble liquid such as water-soluble ink or water-soluble glue containing water and/or polyols as the printing ink, the printing ink is applied to the stencil plate after the process of transferring and adhering the plate-making liquid to the stencil printing original plate. When it is placed on a printing plate and printed, only the areas of the stencil printing plate that are selectively soluble in water or water-soluble liquids swell and dissolve with the moisture or polyol in the printing ink, and are immediately absorbed into the printing material together with the printing ink. Since it is transferred onto the surface and perforated, printed matter can be obtained at the same time as the stencil printing plate is made. This method is not a foolproof method since it does not require steps such as water treatment, but it also eliminates the need for a drying step after water treatment, making it an extremely simple plate-making method.

Furthermore, since the plate-making liquid used in the present invention is a solution containing water, this water can also be used to remove the treated polymer.

As described above, one of the features of the present invention is that a stencil printing plate can be easily made using water or a water-soluble liquid, and printing can be performed without any trouble in handling.

As described above, the present invention is a novel stencil printing plate in which desired characters, patterns, and other designs are simply plate-made with good resolution, a stencil-making method thereof, and a stencil-printing method.

Next, two embodiments of the present invention will be specifically described.
