Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a method for producing a transfer sheet that can form a transfer layer having excellent physical properties such as chemical resistance and solvent resistance on a transfer target. Regarding.

(Prior Art) Traditionally, the method of painting by transfer is often used for painting objects that are difficult to print directly.For example, there are many transfer sheets called hot stamps. It has been used as a simple method for painting paper, synthetic leather, plastic molded products, etc., and is effectively used in a wide range of applications. Most of them have a base film such as polyester, a release layer made of acrylic resin, rubber resin, vinyl resin, etc., and a pattern layer, vapor deposition layer, adhesive layer, etc.

It is a layered product, and after transfer, the release layer acts as a protective layer to protect the pattern layer.

(The problem that the invention is trying to solve) However,
Each of the above layers is manufactured using paint or printing ink made by dissolving resin in a solvent, so although it is resistant to certain solvents, it is generally Ester solvents, ketone solvents,
It had no solvent resistance at all to aromatic solvents.

This not only limits the use of the transfer painting sheet in areas where solvent resistance is required, but also typically involves screen printing letters, marks, etc. on the transfer surface after transfer.
There are drawbacks such as the inability to correct defective products during screen printing, and for this reason, there has been a desire for a transfer sheet with excellent chemical and solvent resistance. Crosslinking is sufficient to obtain solvent resistance, but conventional heat curing methods, such as those using crosslinking agents such as incyanate or epoxy, have the disadvantage that the base sheet cannot be peeled off during transfer. have

The present applicant has already made the following proposal in order to solve the above drawbacks. That is, the release layer of the transfer sheet, which serves as a protective layer that protects the surface after transfer, is made of a prepolymer or oligomer having an ethylenically unsaturated bond in its molecule, a hexamer having an ethylenically unsaturated bond in its molecule, and We have proposed a transfer sheet whose solvent resistance and chemical resistance are significantly improved by forming a layer cured by electron beam irradiation using an electron beam curable material consisting of polythiols and/or polythiols.

As a result of further research, the present inventors found that not only the release layer of the transfer sheet but also the pattern layer was crosslinked by irradiation with ionizing radiation, resulting in even better solvent resistance and chemical resistance. After discovering that it was possible to obtain a sheet with a transfer pattern that was stain resistant, he began research into a manufacturing method. As a result, a release layer containing a polymer and/or monomer (hereinafter referred to as ionizing radiation crosslinkable material) that can be crosslinked by irradiation with ionizing radiation is provided on one side of the base sheet, and the release layer is A possible method is to further provide a pattern layer containing an ionizing radiation crosslinkable material after crosslinking, and then provide an adhesive layer after crosslinking by irradiating ionizing radiation.
In this case, a large number of ionizing radiation irradiation devices are required, or a single ionizing radiation irradiation device has the disadvantage of extremely low production efficiency. The method of irradiating ionizing radiation after forming a layer, then forming a pattern layer containing an ionizing radiation crosslinkable material, and further forming an adhesive layer is a simple manufacturing method, but it causes the following problems: I learned that something can happen.

That is, when irradiated with ionizing radiation, the adhesive layer is also affected by the ionizing radiation, causing the material of the adhesive layer to decompose or crosslink. The adhesive layer may not melt, or even if it melts, its adhesion to the object to be transferred may be poor, or the softening point of the adhesive layer may change, causing the transfer sheet to deteriorate during storage. Problems such as blocking may occur.

(Means for Solving the Problems) As a result of intensive research to solve the above-mentioned drawbacks of the prior art, the present inventor has found that the following invention solves the above-mentioned drawbacks of the prior art. With this in mind, he completed the present invention.

That is, 1 the present invention provides a transfer patterned sheet in which a release layer, a pattern layer, and an adhesive layer are sequentially provided on one side of a base sheet, in which the release layer and the pattern layer are made of an ionizing radiation crosslinkable polymer and/or an ionizing radiation polymerizable polymer. The present invention relates to a transfer painting sheet and a method for producing the same, characterized in that it is a crosslinked layer made of a monomer material and irradiated with ionizing radiation.

To explain the present invention in detail, the transfer painting sheet of the present invention has the above-mentioned structure, and is preferably provided by the following two methods.

(First method) A release layer made of an ionizing radiation crosslinkable material is provided on one side of the base sheet, a pattern layer made of an ionizing radiation crosslinkable material is provided on the release layer, and then an adhesive layer is formed after irradiation with ionizing radiation. How to set up.

(Second method) A release layer made of an ionizing radiation crosslinkable material is provided on one side of the base sheet, a pattern layer made of an ionizing radiation crosslinkable material is provided on the release layer, and a radical scavenger is provided on the pattern layer. An adhesive layer made of a thermoplastic resin or a polymer containing as a constituent component a polymerized unit of a monomer having a methacryloyl group is provided, and then ionizing radiation is irradiated,
A method of crosslinking and curing the release layer and pattern layer.

First, the first method will be explained in detail with reference to the accompanying drawings that schematically show the steps of the method of the present invention.As shown in FIG. Apply a coating agent to form a release layer,
It is dried to form a release layer having releasability from the surface of the base sheet.

Next, on the surface of the release agent layer formed in the above step, a coating agent containing an ionizing radiation crosslinkable material containing a colorant as an essential component is applied and dried to form the pattern of the colorant layer shown in FIG. form a layer.

Next, the release agent layer and the colored pattern layer are crosslinked and cured by irradiation with ionizing radiation.

Further, on the surface of the release agent layer including the picture pattern layer formed in the step, applying a coating agent mainly composed of a thermoplastic resin so as to cover the surface of the picture pattern layer and the surface of the release agent layer, It is dried to form an adhesive layer as shown in FIG. 3 to obtain a transfer painting sheet of the present invention.

Next, the second method will be explained.

In the same manner as the first method described above, a release agent layer is formed on the base sheet shown in FIG. 1, and a pattern layer shown in FIG. 2 is further formed. A coating agent mainly composed of a thermoplastic resin containing a scavenger is applied and dried to form the adhesive layer shown in FIG. 3.

Next, the entire sheet obtained is irradiated with ionizing radiation through the adhesive layer to crosslink and cure the release agent layer and the pattern layer.

In the above description, a picture pattern layer is used as one coloring agent layer, but the adhesive layer may of course be a plain coloring layer formed uniformly over the entire surface.

Furthermore, an intermediate layer such as a metal vapor deposition layer may be provided between the one-color pattern layer and the adhesive layer.

As the base sheet used in the method of the present invention, various plastic films such as polyester film, cellophane film, and polypropylene film, paper, metal foil, etc. can be used alone, or if necessary, sheets formed by laminating two or more of them. be. Furthermore, for example, an ink composition in which an extender pigment is added to a vehicle prepared by dissolving polyester resin, polyurethane resin, cellulose resin, or polyether resin in a solvent, and if necessary, a water repellent such as silicone, an oil repellent, etc. are added. Using a sheet that has been matted by providing unevenness of 0.5 to 5 pm on the sheet surface using a material, or a sheet that has a convex pattern layer of 51 Lm or more on the sheet surface, By forming a release agent layer on the surface having the pattern layer, an uneven pattern or a convex pattern is formed on the surface of the resulting transferred painted layer, and the gap between the base sheet and the release agent layer is It is also possible to improve the releasability.

In addition, as the ionizing radiation crosslinking material used to form the pattern layer which is the coloring agent layer of the release agent layer 1, polymers (crosslinked polymers) that are generally crosslinked by irradiation with ionizing radiation, such as polystyrene, polyacrylic ester, Homopolymers such as polyacrylamide, polyvinyl alcohol, polyvinyl acetate, polyacrylonitrile, polyvinylmethylketone, polyvinylpyrrolidone, polyvinylpyridine, polyvinyl chloride, or copolymers with other components containing the above polymer structure, natural rubber, neoprene, Examples include polyester resin, polyurethane resin, polyamide resin, dimethylpolysiloxane, chlorinated polyethylene, chlorinated polypropylene, and polyvinyl butyral resin. The above-mentioned crosslinked polymer can be dissolved in a solvent and used alone as a coating agent, but generally polymers that decompose by irradiation with ionizing radiation (degradable polymer),
For example, in the case of polymers such as polymethacrylic acid esters, polyvinylidene chloride, cellulose derivatives such as nitrocellulose, methylcellulose, and ethylcellulose, and polyisobutylene, radically polymerizable unsaturated groups are introduced into the polymer, or radically polymerizable unsaturated groups are introduced into the molecule. As a polymer, oligolimer or monomer having a radically polymerizable unsaturated bond in its molecule, it is necessary to mix it with a monomer having a radically polymerizable unsaturated bond to create a composition that can be crosslinked and cured by ionizing radiation. For example, unsaturated polyesters, polyester acrylate, epoxy acrylate, urethane acrylate, polyether acrylate, polyol acrylate, various acrylates such as melamine acrylate, polyester methacrylate, epoxy methacrylate, urethane methacrylate, polyether methacrylate, polyol methacrylate, melamine methacrylate. Various methacrylates such as styrene, α-

In addition, by using the above-mentioned monomer having a radically polymerizable unsaturated bond in combination with the above-mentioned crosslinked polymer, it is possible to further increase the crosslinking density during ionizing radiation irradiation, making it effective. be.

The mixing composition ratio can be arbitrarily mixed and used. In forming the release agent layer and pattern layer, a coating agent containing the above-mentioned ionizing radiation crosslinked material as an essential component is applied and dried. When this happens, it is necessary to perform drying to the touch, which is a dry state in which the coating agent does not adhere to the fingertips, that is, dry to the touch. Therefore, - a coating agent containing a solvent is used in each of these steps, and the coating agent contains a solvent as an essential component of the ionizing radiation crosslinkable material, and after the coating agent is applied, the solvent in the coating agent is volatilized by heating. The method of drying to the touch, or using a coating agent in which a photopolymerization initiator is added to a coating agent that also has an ionizing radiation crosslinkable material as an essential component, and applying ultraviolet irradiation treatment after applying the coating agent. It is preferable to use the dry-to-touch method of curing the surface of the layer in order to obtain the transfer sheet through continuous production.

The dry-to-touch method, in which the solvent in the applied coating agent is volatilized by heating, uses an ionizing radiation-curable composition containing 90% or less of a low-boiling point volatile solvent as the coating agent, and then applies the coating agent. Afterwards, the surface of the coating agent layer is dried to the touch by heating in a drying hood to volatilize the solvent. Some of its attributes include the fact that it can be easily adjusted according to the type of application method utilized. In addition, the dry-to-touch method in which the surface of the applied layer, that is, the surface of the applied coating agent layer, is cured by ultraviolet irradiation treatment uses a coating agent that contains 10% by weight or less of a photopolymerization initiator in advance, After applying the coating agent, ultraviolet rays are irradiated to harden the surface of the coating layer.
It can be carried out using simple equipment that only requires installing 1 to 10 lights (w/cm). Photopolymerization initiators used at this time include various benzoin ethers such as benzoin methyl ether, benzoin propyl ether, benzoin n-butyl ether, and benzoin isobutyl ether, benzophenones, halogenated acetophenones, and biacyl. A material that generates radicals when exposed to ultraviolet rays is used.

Furthermore, it is of course possible to add a slip agent or the like as appropriate to the coating agent for forming the release agent layer, taking into consideration the surface physical properties of the transfer painting layer on which the release agent layer is formed. .

The coating agent for forming the picture pattern layer, which is the coloring agent layer, can be one containing an ionizing radiation crosslinking material and a coloring agent such as a pigment having a desired color.

The metal vapor deposition layer can be formed by a conventional metal vapor deposition method.

Next, as a means for crosslinking and curing the ionizing radiation crosslinkable material forming the release agent layer and the colored pattern layer, electron beam,
Gamma rays are preferred, and crosslinking and curing can be achieved by irradiation at 0.5 Mrad to 20 Mrad.

In the case of the first method, an adhesive layer is provided after irradiation with ionizing radiation, but there are no particular restrictions on the thermo-tIT plastic resin that forms the adhesive layer, and the adhesiveness to the object to be transferred is taken into consideration. For example, vinyl polymer, polyester resin.

In the case of the second method, there are polyurethane resins, polyamides, resins, rosin derivatives, etc., but are not limited to these.
An adhesive layer is provided before the release layer and the pattern layer are irradiated with ionizing radiation, and the method is characterized in that a radical scavenger is mixed into the thermoplastic resin forming the adhesive layer. The radical scavenger is used to capture radicals generated in the adhesive layer during irradiation with ionizing radiation and prevent crosslinking or decomposition of the thermoplastic resin. Compounds having a phenolic hydroxyl group include phenol, cresol, xylenol, carvacrol, thymol, naphthol, catechol, resorcinol, hydroquinone, pyrogallol, phlolotarcin, phenolphthalein, P-methoxyphenol, P-ethoxyphenol, nopolatsk, 0 -Phenylphenol, etc. Compounds having at least one quinone structure in one molecule include P-benzoquinone, O-benzoquinone, cyphenoquinone, anthraquinone, naphthoquinone, non, etc., and diphenylpicryl Examples include hydrazyl, ferdazyl, nitrobenzene, diphenylamine, diphenylbifurylhydrazine, etc.

Such radical scavengers: 0 for thermoplastic resins.
．． It is preferably 1% by weight or more and 10% by weight or less, but the heat of
This does not apply to plastic resins that have the above-mentioned phenolic hydroxyl group or quinone structure.

In addition, when polybu having a polymerized unit of a monomer having a methacryloyl group is included as a component constituting the adhesive layer, even after irradiation with the above-mentioned ionizing radiation conditions, the adhesive of the transfer painting sheet will be sufficient. Can be used as a coating layer.

Here, the polymer having a polymerized unit of a monomer having a methacryloyl group is a polymer having the following structural unit in the polymer main chain.

[However, R represents H or an alkyl group having 1 or more carbon atoms. ] If the above polymer is a copolymer of a monomer having a methacryloyl group and another polymerizable monomer, the monomer having a methacryloyl group may be contained in a proportion of 30 mol% or more. preferable.

As the polymer, for example, methyl methacrylate (co)
Examples include ethyl methacrylate (co)polymer, propyl methacrylate (co)polymer, and butyl methacrylate (co)polymer.

The second method is characterized in that after the adhesive layer is provided, ionizing radiation is irradiated as described above.

In the coating agent for forming the adhesive layer, especially for the purpose of imparting hiding properties to the coating agent,
It is preferable to contain an opaque pigment or the like.

Coating methods for forming these release agent layers, pattern layers (coloring agent layers), adhesive layers, etc. include natural roll coating, reverse roll coating,
Various coating methods such as gravure roll coating, air knife coating, curtain flow coating, and myobar coating, and various printing methods such as gravure printing, offset printing, screen printing, and offset gravure printing can be used.

(Function effect) According to the present invention as described above, in the transfer sheet of the present invention, the inner layer of the release layer and the pattern layer are both cross-linked and hardened layers with electron beams, so that after being transferred to a transfer object, The surface of the transferred pattern layer is covered with a release layer, that is, a protective layer cross-linked and cured with electron beams, and the pattern layer is also covered with a protective layer, so it exhibits excellent durability against all kinds of solvents and chemicals, and has excellent surface strength. Other physical properties are also significantly improved.

Furthermore, according to the method of the present invention, the release layer and the pattern layer need only be irradiated with an electron beam once, and according to the second manufacturing method, it is sufficient to irradiate the release layer and the pattern layer with the electron beam only once in the final step. The process is significantly simplified and high productivity can be achieved.
