Description

  The present invention relates to a hydraulic transfer film capable of simultaneously transferring a curable resin layer, or a curable resin layer and a decorative layer, onto the surface of an object to be transferred such as various molded articles, and a hydraulic pressure produced using the hydraulic transfer film. It relates to the transfer body.

  The hydraulic transfer method is a method that can add a decorative layer rich in design to a molded product with a complicated three-dimensional shape.To make the hydraulic transfer film follow the surface of a complex three-dimensional molded product, The transfer film itself must have sufficient flexibility.

Making the hydraulic transfer film flexible is activation in a so-called hydraulic transfer method.
Activation is to redissolve the transfer layer formed into a film with an organic solvent. When the transfer layer is composed of a composite layer in which a curable resin layer and a decorative layer are laminated, the decorative pattern must be softened without breaking, and the laminated structure must be maintained. Moreover, when a transfer layer consists of a curable resin layer, it must be made flexible while holding the curable resin layer.

In the hydraulic transfer process, the transfer layer of the hydraulic transfer film is activated by an organic solvent, and at the same time, the support film made of a water-soluble or water-swellable resin increases in degree of swelling with water. . Therefore, the transfer layer of the hydraulic transfer film expands before transfer, and the transferred decoration is in an expanded state as compared with the original film. Furthermore, the elongation percentage of the pattern partially changes by pressing the transfer target. That is, when the decorative layer is a pattern, the entire decoration layer extends and becomes a blurred pattern. In addition, when the decoration layer is solid in a single color, shading unevenness occurs. Alternatively, when the transfer layer is made of a curable resin layer, the elongation rate of the curable resin layer is uneven, the film thickness is partially different, and a problem occurs in appearance and physical properties.
For this reason, considerable skill is required to hydraulically transfer to a molded product having a complicated three-dimensional shape without disturbing the high design and appearance of the decorative layer, and the manufacturing process is complicated in the production of the molded product by the hydraulic transfer method. Therefore, the cost is high, and hydraulic transfer products manufactured by the hydraulic transfer method are limited to high-grade products.

In order to eliminate such unnecessary expansion of the film, a water-insoluble expansion preventing layer that does not exhibit flexibility or tackiness by adding an organic solvent is provided so as to surround the decorative layer provided on the support film. Due to this, during the hydraulic transfer, the area of the decoration layer is prevented from expanding in the area surrounded by the anti-swelling layer, and a beautiful pattern that does not differ from the size and color of the pattern expressed on the hydraulic transfer film is imparted to the three-dimensional object. Technology is disclosed. (For example, refer to Patent Document 1.)
However, in the hydraulic transfer film described in Patent Document 1, since the effect is limited to the region surrounded by the expansion prevention layer, it is necessary to change the setting of the expansion prevention layer according to the shape of the manufactured item, The complexity and versatility of the manufacturing process could not be essentially eliminated.

JP-A-6-206398

  The problem to be solved by the present invention is to suppress unnecessary expansion associated with the activation of the transfer layer, without causing unevenness in the color of the decorative layer, deterioration of design due to enlargement or color blur, etc. Another object of the present invention is to provide a water pressure transfer film capable of producing a water pressure transfer product that reproduces the above decoration, and a water pressure transfer body using the film.

  As a result of intensive studies to solve the above-mentioned problems, the present inventors have introduced an additive having a function of suppressing the swelling of the transfer layer into the curable resin layer, thereby preventing problems caused by the activation of the hydraulic transfer film. It has been found that a water pressure transfer product that can suppress the necessary expansion and can be activated uniformly and reproduce the original decoration of the film can be produced.

  That is, the present invention has a support film made of a water-soluble or water-swellable resin and a transfer layer soluble in an organic solvent provided on the support film, and the transfer layer is irradiated with active energy rays. Provided is a hydraulic transfer film having a curable resin layer containing inorganic fine particles or organic fine particles, which can be cured by at least one kind of heating.

  Further, the present invention provides an inorganic fine particle or an organic fine particle which can be cured by at least one of active energy ray irradiation and heating on a support film made of a water-soluble or water-swellable resin and can be activated with an organic solvent.

  Further, the present invention provides an inorganic fine particle or an organic fine particle which can be cured by at least one of active energy ray irradiation and heating on a support film made of a water-soluble or water-swellable resin and can be activated with an organic solvent. A film (A) laminated in the order of a curable resin layer containing an adhesive, an adhesive layer, and a film (B) provided with a decorative layer soluble in an organic solvent comprising a printing ink film or a paint film on a peelable film; Is provided so that the adhesive layer of the film (A) and the decorative layer of the film (B) face each other and are bonded by dry lamination.

  Further, the present invention provides the hydraulic transfer film described above, after peeling the peelable film from the film, floating in water with the support film down, activating the transfer layer with an organic solvent, A hydraulic transfer body is provided in which the layer is transferred to a transfer medium, the support film is removed, and then the transfer layer is cured by at least one of active energy ray irradiation and heating.

  In the hydraulic transfer film of the present invention, the curable resin layer contains inorganic fine particles or organic fine particles having swelling suppressing ability. Therefore, when the curable resin layer or the decorative layer is activated with an organic solvent, the expansion of the curable resin layer itself or the decorative layer laminated on the curable resin layer can be suppressed to a minimum. The enlargement of the pattern, color blur, or uneven thickness of the curable resin layer can be prevented.

(Support film)
The support film used for the hydraulic transfer film of the present invention is a film made of a water-soluble or water-swellable resin.
Examples of resins comprising water-soluble or water-swellable resins include polyvinyl alcohol (PVA), polyvinyl pyrrolidone, acetyl cellulose, polyacrylamide, acetyl butyl cellulose, gelatin, glue, sodium alginate, hydroxyethyl cellulose, carboxymethyl cellulose, etc. it can. Among them, a PVA film generally used as a hydraulic transfer film is particularly preferable because it is easily dissolved in water, easily available, and suitable for printing a curable resin layer. These resin layers may be a single layer or multiple layers, and the layer thickness is preferably about 10 to 200 μm.

(Transfer layer (curable resin layer, decorative layer, swelling suppression layer))
Next, the transfer layer provided on the support for the hydraulic transfer film of the present invention will be described. The transfer layer is composed of a curable resin layer or a composite layer in which a curable resin layer and a decoration layer are laminated. Moreover, in order to improve the effect of this invention more, you may have further the swelling suppression layer which is a resin layer containing 40 mass% or more of inorganic fine particles or organic fine particles.

(Curable resin layer fine particles A)
The curable resin layer contains a curable resin curable by at least one of active energy ray irradiation and heating, and inorganic fine particles or organic fine particles (hereinafter, “inorganic fine particles or organic fine particles” are abbreviated as fine particles A). . When the decorative layer is laminated, it is preferable that the curable resin layer is transparent because the design of the decorative layer of the obtained hydraulic transfer body can be expressed well. However, depending on the required characteristics and design properties of the hydraulic transfer body, it is sufficient that the color and pattern of the decorative layer of the hydraulic transfer body to be basically obtained can be seen through, and that the curable resin layer is completely transparent. It does not need to include transparent to translucent ones. Moreover, it may be colored.

  As inorganic fine particles, inorganic pigments such as inorganic pigments, carbon, titanium oxide, kraftite, and zinc white; lime carbonate powder, precipitated calcium carbonate, gypsum, clay (China Clay), silica powder, diatomaceous earth, talc, kaolin, Inorganic pigments such as alumina white, barium sulfate, aluminum stearate, magnesium carbonate, barite powder, abrasive powder, etc .; silicone, glass beads and the like.

  Examples of the organic fine particles include organic coloring pigments, organic crystals, and polymer fine particles. Examples of organic coloring pigments include general-purpose pigments such as azo pigments, phthalocyanine pigments, selenium pigments, and quinacridone pigments. Depending on the particle size and amount of addition, the organic color pigment has a concealing effect on the base layer (transfer base material) in the case where the decorative layer in the transfer layer or the decorative layer is not provided, depending on the particle size and addition amount. What is necessary is just to control a particle size and addition amount.

Examples of the organic crystal include crystalline polyurea, crystalline polyurethane, crystalline polyamide, crystalline amino acid, crystalline polypeptide, crystalline organometallic complex, and the like.
Examples of the polymer particles include crosslinked acrylic particles, crosslinked polystyrene resin particles, crosslinked urethane particles, phenol resin particles, silicone resin particles, polyethylene particles, fluorine particles, melamine particles, polycarbonate particles, and phenol particles. .

  Among the fine particles A, inorganic pigments, organic crystals, and polymer fine particles are preferable because they have a high swelling suppressing effect, and inorganic extender pigments and organic crystals are preferable because they are particularly effective.

In the present invention, the curable resin layer has a role of protecting the decorative layer as an original top coat, and also swells when the decorative layer is activated by an organic solvent, so that the pattern of the decorative layer is enlarged or color blur is caused. It plays the role of preventing the deterioration of design properties such as. The activation mentioned here means that the resin constituting the transfer layer is solubilized without being completely dissolved by applying or spraying an organic solvent to the transfer layer, and the transfer layer is transferred with flexibility. It means to improve the followability and adhesion of the layer to the transferred body of the three-dimensional curved surface. Therefore, the organic solvent that exhibits the activation action has the ability to dissolve the decorative layer.
In other words, the phenomenon that the decorative layer pattern is enlarged or blurred is caused by the fact that the resin material of the printing ink or paint in the decorative layer is dissolved in the organic solvent, so that the colorant particles such as dyes and pigments are separated from each other. Or by mixing.
The curable resin layer containing the fine particles A is resistant to swelling of the resin, and suppresses the adjacent decorative layer from excessively swelling due to its suppressed swelling state. Therefore, the fine particles A are preferably those that do not dissolve or swell in the organic solvent for activation, the resin used for the curable resin layer, or the like. Further, since the fine particles A impart thixotropic properties to the curable resin layer in an activated state, when the transferred object is pressed against the hydraulic transfer film at a low speed, the fine particles A are resistant to the shear stress applied to the hydraulic transfer film. Thus, resistance is generated, and the deterioration of the design property of the transfer layer in the transfer process is also suppressed, and the three-dimensional curved surface is followed and is easily adhered.

  In the present invention, the curable resin layer preferably contains 0.1% by mass or more of the fine particles A. The content of the fine particles A may be appropriately determined according to the absorption amount of the organic solvent, but is preferably 0.1 to 40% by mass, more preferably 0.2 to 30% by mass, and still more preferably 0.2 to 20%. % By mass.

  The fine particles A may have a spherical shape or an indefinite shape, but a spherical shape or a shape close thereto is preferable. Moreover, it is preferable that the magnitude | size of this fine powder is 0.001-30 micrometers from a viewpoint of the dispersibility to a coating material, and the smoothness of the surface. Of course, the range of the optimum particle diameter differs in relation to the film thickness, but for example, in the case of a film thickness of about 20 μm, it is preferably 0.001 to 10 μm.

  The fine particles A also affect the appearance of the transferred product, and can control the design from gloss to matte. Further, by changing the shape, size and the like of the fine particles A, it is possible to control from a smooth surface to an embossed surface. Therefore, the composition and concentration of the fine particles A may be adjusted so as to obtain a desired design by combining with a base such as a decoration layer.

  In particular, among the fine particles A, lime carbonate powder, precipitated calcium carbonate, gypsum, clay (China Clay), silica powder, diatomaceous earth, talc, kaolin, alumina white, barium sulfate, aluminum stearate, magnesium carbonate, barite powder, Organic extender pigments such as abrasive powders, crosslinked acrylic particles, crosslinked polystyrene resin particles, crosslinked urethane particles, phenol resin particles, silicone resin particles, polyethylene particles, fluorine particles, melamine particles, polycarbonate particles and phenol particles These are used as matting agents, and by using these, it is possible to obtain a hydraulic transfer body that is excellent in surface properties and has a matte tone that gives a high-class design feeling. Among them, silica powder is preferable because a high matting effect can be obtained with a small amount of addition.

  The matting agent may have a spherical shape or an indefinite shape, but preferably has a spherical shape or a shape close thereto. Further, the size of the fine powder is preferably 0.05 to 30 μm from the viewpoint of dispersibility in paint, matteness of efficiency, and surface smoothness. Of course, the range of the optimum particle diameter varies depending on the film thickness, but for example, in the case of a film thickness of about 20 μm, it is preferably 0.5 to 10 μm.

  The use method and addition amount of the matting agent may be the same as the method and addition amount used for paints and inks, which are general purpose uses of the matting agent. For example, when using a matting agent that provides a matting effect by adding 20% to the resin solid content of the paint, add 10% to the resin solid content of the curable resin layer used in the present invention. By doing so, a sufficient matting effect can be obtained after the hydraulic transfer.

  Since the refractive index of the fine particles A when used as a matting agent can scatter light more efficiently, it is preferable that the difference from the refractive index of the coating resin is large. By using and transferring by hydraulic pressure, the matte property can be efficiently exhibited, so that there is no need to provide a restriction. Rather, fine particles A having a small difference in refractive index can be used so as to make full use of the pattern and color of the base.

  The degree of matte tone can be evaluated by surface gloss. It can be said that the smaller the surface gloss, the more matte. It can be said that the gloss of the surface gloss (%) is preferably 20 or less. More preferably, it has a matte tone having a gloss of 10 or less.

(1) Curable resin layer containing active energy ray-curable resin The active energy ray-curable resin is an oligomer and a polymer having a polymerizable group or a structural unit curable by active energy rays in one molecule. The active energy rays referred to here are ultraviolet rays and electron rays, and both oligomers and polymers that are cured by these can be used, but ultraviolet curable resins are particularly suitable.

  As the ultraviolet ray source, a low-pressure mercury lamp, a high-pressure mercury lamp, an ultrahigh-pressure mercury lamp, a carbon arc lamp, a metal halide lamp, a xenon lamp, or the like is used.

Particularly preferably used. These may be used alone or in combination of two or more.

  The curable resin layer containing these active energy ray-curable resins may contain a conventional photopolymerization initiator or photosensitizer as necessary.

You can also

(2) Curable resin layer containing active energy ray curable resin and thermoplastic resin The curable resin layer containing active energy ray curable resin and thermoplastic resin contains the active energy ray curable resin and thermoplastic resin described above. . Use of a thermoplastic resin in combination with an active energy ray curable resin is extremely effective in reducing the tackiness of the curable resin layer, improving the glass transition temperature (Tg), and improving the cohesive fracture strength of the curable resin layer. . However, if the amount of the thermoplastic resin to be included in the curable resin layer is large, the curing reaction of the curable resin is inhibited. Therefore, the thermoplastic resin should be 70 parts by mass with respect to 100 parts by mass of the total resin of the curable resin layer. It is preferable to add in the range which does not exceed.

  The thermoplastic resin is compatible with the active energy ray curable resin to be used, and specific examples include polymethacrylate, polystyrene, polyvinyl chloride, polyvinylidene chloride, polyvinyl acetate, and polyester. These may be a homopolymer or a copolymer of a plurality of monomers. The thermoplastic resin is preferably non-polymerizable.

  Among them, polystyrene and polymethacrylate are preferable because they have high Tg and are suitable for reducing the adhesiveness of the curable resin layer, and in particular, polymethacrylate mainly composed of polymethyl methacrylate is transparent, solvent resistant, and It is preferable at the point which is excellent in abrasion resistance.

  Further, the molecular weight and Tg of the thermoplastic resin have a great influence on the film-forming ability. In order to suppress the fluidity of the curable resin and facilitate activation of the curable resin layer with an organic solvent, the mass average molecular weight of the thermoplastic resin is preferably 3,000 to 400,000, more preferably 10,000. The Tg is preferably 35 ° C to 200 ° C, more preferably 35 ° C to 150 ° C. When using a thermoplastic resin having a relatively low Tg of around 35 ° C., the mass average molecular weight of the thermoplastic resin is preferably 100,000 or more.

Further, the active energy ray-curable resin is a polyurethane (meth) acrylate having three or more (meth) acryloyl groups in one molecule, and the thermoplastic resin is a polymethacrylate, particularly polymethyl methacrylate. An especially preferred resin layer is preferred.

(3) Curable resin layer containing a thermosetting resin The thermosetting resin is a compound having in its molecule a functional group that is polymerized by the action of heat or a catalyst, or a curing agent as a main component of the thermosetting compound. A heat-reactive compound is blended. Examples of the functional group that is polymerized by the action of heat or a catalyst include an N-methylol group, an N-alkoxymethyl group, an epoxy group, a methylol group, an acid anhydride, and a carbon-carbon double bond.

  For those having a carbon-carbon double bond in the molecule and capable of crosslinking reaction by polymerization, curable resins of the same type as the active energy ray curable resin can be used, and these curable resins and radical sources by heating. It can be used as a thermosetting resin by combining with a thermopolymerization initiator that generates. As the thermal polymerization initiator at this time, usual thermal polymerization initiators such as benzoyl peroxide and azobisisobutyronitrile are used.

  Specific combinations of the main agent and the curing agent include, for example, a main resin having a hydroxyl group or an amino group and an isocyanate as a curing agent; a main resin having a hydroxyl group or a carboxyl group and an N-methylol or N-alkoxymethyl as a curing agent. Amino resins such as melamine and benzoguanamine; main resin having epoxy group and hydroxyl group and acid anhydride such as phthalic anhydride as curing agent; main resin having carboxyl group, carbon-carbon double bond, nitrile group and epoxy group A phenol resin as a curing agent; a main resin having a carboxyl group or an amino group and an epoxy group-containing compound as a curing agent can be used.

  Many of these thermosetting resins undergo a gradual curing reaction during storage even at room temperature. If the curing reaction proceeds during the storage period, the transfer layer is not sufficiently activated by the organic solvent, which causes a transfer failure. For this reason, among thermosetting resins, a system using polyol as the main agent and blocked isocyanate as the curing agent is preferable.

  As the blocked isocyanate, those obtained by protecting an isocyanate group with a conventional blocking agent can be used. Examples of the conventional blocking agent include phenol, cresol, aromatic secondary amine, tertiary alcohol, lactam, oxime and the like.

As the block isocyanate, a block isocyanate having a suitable desorption temperature for the block group may be selected in accordance with the heat resistance of the decorative layer and the heat resistance of the transfer target.
Examples of the polyol include acrylic polyol, poly-p-hydroxystyrene, polyester polyol, and polyethylene vinyl alcohol copolymer. Acrylic polyol is particularly preferable, and an acrylic having a mass average molecular weight of 3,000 to 100,000 is particularly preferable. Polyols, more preferably 10,000 to 70,000 acrylic polyols are suitable.

  Since the thermosetting resin also needs printability or coatability, it is preferable that the resin has a high molecular weight before curing, preferably a mass average molecular weight of 1,000 to 100,000, more preferably 3,000 to 30,000. . More specifically, those containing a polyol (particularly preferably acrylic polyol) having a mass average molecular weight of 3,000 to 100,000, more preferably 10,000 to 70,000 as a main component and a blocked isocyanate as a curing agent are preferably used. .

(4) Curable resin layer containing a thermosetting resin and a thermoplastic resin As the curable resin layer containing a thermosetting resin and a thermoplastic resin, the thermosetting resin described in (3), and (2) The thermoplastic resin described is included.
The thermosetting resin to be used is the same as the thermosetting resin described in (3), and the preferred thermosetting resin is also a blocked isocyanate and a polyol as in (3). Particularly, the polyol is an acrylic polyol. The weight average molecular weight is 3,000 to 100,000, more preferably 10,000 to 70,000.

  When a blocked isocyanate and a polyol are used as the thermosetting resin, since the polyol generally has a coating film forming ability, the amount of the thermoplastic resin used in combination may be small. The thermoplastic resin to be used must be compatible with the thermosetting resin to be used. When a blocked isocyanate and a polyol are used as the thermosetting resin, a thermoplastic resin that is soluble in the polyol is preferable. As the thermoplastic resin, a thermoplastic resin having a Tg of 35 ° C. to 200 ° C., more preferably a Tg of 35 ° C. to 150 ° C., and a mass average molecular weight of 3000 to 400,000 is preferably used. Methacrylate is preferred. The thermoplastic resin is preferably non-polymerizable.

(5) Curable resin layer containing active energy ray curable resin and thermosetting resin As the curable resin layer containing active energy ray curable resin and thermosetting resin, the active energy rays described in (1), respectively.

For example, it contains (meth) acrylate having three or more (meth) acryloyl groups in one molecule, blocked isocyanate and polyol.

  Especially, what contains each preferable resin of the active energy ray-curable resin described in (1) and each preferable resin of the thermosetting resin described in (3) is preferable, for example, mass average molecular weight 300-1 More preferably, an oligomer or polymer having three or more (meth) acryloyl groups in one molecule of 300 to 5,000, particularly preferably a polyurethane (meth) acrylate, or a blocked isocyanate and a weight average molecular weight of 3,000 to 3,000. It contains 100,000, more preferably 10,000 to 70,000 acrylic polyols.

(6) Curable resin layer containing active energy ray curable resin, thermosetting resin and thermoplastic resin The curable resin layer containing active energy ray curable resin, thermosetting resin and thermoplastic resin is (1) It is a curable resin layer containing the active energy ray-curable resin described in 1., the thermosetting resin described in (3), and the thermoplastic resin used in combination with the active energy ray-curable resin described in (2). The thermoplastic resin is preferably non-polymerizable.

The curable resin layer must be able to be activated by an organic solvent during hydraulic transfer. Therefore, the curable resin layer must have improved solubility in organic solvents as the film thickness increases. However, the curable resin layer also requires shape stability (storage stability) as a hydraulic transfer film having an uncured curable resin layer, and in order to balance such contradictory requirements, The thermoplastic resin layer preferably contains a thermoplastic resin.
In the activation of the present invention, the activator lands on the transfer layer, the activator penetrates quickly, and the curable resin layer can be dissolved (activated). In addition, by including a thermoplastic resin, the curable resin layer has a moderate resistance to the penetration of the activator and has a firm self-holding power before curing, and is activated more gently. This makes it possible to suppress uneven dissolution of the curable resin layer and cracking of the decorative layer due to rapid activation.

In order to ensure the solubility of the curable resin layer at the time of transfer, it is preferable to use 45% by mass or more of a resin that can be cured by at least one of highly soluble active energy rays and heating.
On the other hand, the amount of the thermoplastic resin contained in the curable resin layer is preferably 25% by mass or more, more preferably, in order to better ensure the forming ability, drying property, and storage stability of the curable resin layer. Is 30% by mass or more.
Therefore, the mass ratio P of the resin that can be cured by at least one of active energy rays and heating with respect to the thermoplastic resin of the present invention: (mass sum of radical polymerizable compounds) / (mass sum of thermoplastic resins) is 45/55. It is preferably 75/25 or less, more preferably 50/50 or more and 70/30 or less, and most preferably 60/40.

In order to facilitate activation with an organic solvent, it is preferable to use a polyacrylate having a mass average molecular weight of 20,000 to 300,000 or a polyester having a mass average molecular weight of 5,000 to 50,000 as the thermoplastic resin.
When the molecular weight of the thermoplastic resin used exceeds the above range, activation of the curable resin layer with an organic solvent tends to be difficult. On the other hand, if the molecular weight is below the above range, it is difficult to suppress the fluidity and tackiness of the uncured curable resin layer, and the cured resin film moves to the coating film surface at a high temperature. Reduce performance.
Moreover, in order to improve the drying property at the time of coating film formation, it is preferable to use a polyacrylate having a mass average molecular weight of 150,000 or more or a polyester having a mass average molecular weight of 30,000 or more as the thermoplastic resin.
On the other hand, the glass transition temperature (Tg) of the thermoplastic resin is preferably 25 ° C to 250 ° C, more preferably 50 ° C to 150 ° C. If the Tg of the thermoplastic resin is less than 20 ° C., it is difficult to suppress the adhesiveness of the uncured curable resin layer, and adversely affects the heat resistance of the cured coating film. And curable resin become difficult to mix.

  The above-described curable resin layer has a greater surface protection effect of the obtained hydraulic transfer body as the dry film thickness is thicker, and has a greater effect of absorbing irregularities of the decorative layer, so that the molded product has an excellent gloss. This is preferable. Therefore, in order to satisfy the function as the protective layer and the effect of absorbing the irregularities of the decorative layer, the dry film thickness of the curable resin layer is preferably 3 to 200 μm, and the uncured curable resin layer is stored. From the viewpoint of stability, it is preferably 100 μm or less. However, if the dry film thickness is too thick, activation (solubilization) of the curable resin layer by the organic solvent tends to be insufficient. Therefore, in order to sufficiently activate the curable resin layer with an organic solvent and to satisfy the function as a protective layer and the designability, the thickness is preferably 5 to 30 μm.

(Decoration layer)
The printing ink or paint used for forming the decorative layer of the hydraulic transfer film of the present invention is preferably activated with an organic solvent so that sufficient flexibility can be obtained when the transfer layer is transferred to the transfer target. It is preferable to form with a gravure printing ink from the viewpoint that an image quality image is easily obtained. A colored layer having no pattern can also be formed by coating.

  Resin used for the decoration layer, that is, base resin used for printing ink or paint is acrylic resin, polyurethane resin, polyamide resin, urea resin, epoxy resin, polyester resin, vinyl resin (vinyl chloride, vinyl acetate, PVC-vinegar) Uses thermoplastic resins such as vinyl copolymer resins), vinylidene resins (vinylidene chloride, vinylidene fluoride), ethylene-vinyl acetate resins, polyolefin resins, chlorinated olefin resins, ethylene-acrylic resins, petroleum-based resins, and cellulose derivative resins. It is done. Among these, polyurethane resins, polyester resins, and vinyl chloride-vinyl acetate copolymer resins are preferably used because of their excellent solubility in organic solvents, fluidity, pigment dispersibility, and transferability, and polyurethane resins and polyester resins are preferred. A polyurethane resin is particularly preferred.

  The resin used for the decorative layer, that is, the polyurethane resin used for printing ink or paint, has a number average molecular weight (measured by GPC using a polystyrene calibration curve) of 2,000 to 60,000, more preferably 2,500 or more. Those having a molecular weight of 56,000 or less, more preferably 2,500 or more and 40,000 or less, are preferable because they have solubility in an organic solvent and appropriate adhesion to a peelable film. When the number average molecular weight of the polyurethane resin is smaller than 2,000, the weather resistance is lowered, and when the number average molecular weight is larger than 60,000, the glass transition temperature is increased, and the adhesiveness and fluidity of the printing ink or paint are increased. , Pigment dispersibility and transferability are reduced. In addition, the glass transition temperature of the polyurethane resin is preferably −5 ° C. or more and 70 ° C. or less because it has solubility in an organic solvent and appropriate adhesion to a transfer target.

  A polyurethane resin having a low hydroxyl value is preferred, and a polyurethane having no hydroxyl group is preferred. The higher the hydroxyl value of the polyurethane resin, the more easily the polyurethane resin molecules become macromolecules due to hydrogen bonds or the like, and the glass transition temperature tends to increase and the transferability tends to decrease.

  The number average molecular weight of the resin used in the decorative layer, that is, the polyester resin used in the printing ink or paint is preferably 2,000 to 8,000 in order to have appropriate adhesion to the peelable film, and more Preferably it is 2,500-7,500, and most preferably 2,500-7,000. When the number average molecular weight is less than 2,000, the flexibility and elongation at break are lowered, the followability to the transferred material at the time of transfer is lowered, and the image quality of the decorative layer formed on the obtained hydraulic transfer body is improved. descend. If the number average molecular weight is larger than 8,000, the polyester resin molecules tend to become large molecules due to hydrogen bonding or the like, the glass transition temperature becomes high, and the transferability decreases. Moreover, it is preferable that the glass transition temperature of the polyester resin used for printing ink or a coating material is -5 degreeC or more and 70 degrees C or less from having moderate adhesiveness with a to-be-transferred material.

  The resin used in the decorative layer, that is, the polyester resin used in the printing ink or paint is preferably a polyester having a small hydroxyl group, specifically a polyester having a hydroxyl value of 5 or less.

  When the hydroxyl value of the polyester resin is large, the polyester resin molecules tend to become large molecules due to hydrogen bonds or the like, the glass transition temperature becomes high, and the transfer property of the printing ink or paint tends to be lowered. When other resins are blended and the glass transition temperature of ink or paint is prepared to be low, it is preferable to use the above polyurethane resin as a resin other than the polyester resin.

In order to adjust the peeling force between the decorative layer and the peelable film, the decorative layer may contain a release agent. The release agent to be used is not limited at all as long as it can be dispersed in the decoration layer formed into an ink or paint. However, it is preferable to use a fluorine-based compound or a silicone-based compound, and it is easy to control the molecular weight and chemical structure. Compounds are particularly preferred. Among silicone compounds, polyether-modified polysiloxanes and polysiloxane-polyether block copolymers can be suitably used.
The content of the silicone compound in the printing ink or paint is preferably 0.01% by mass or more and 6.0% by mass or less, more preferably 0.05% by mass or more and 4.0% by mass or less in the nonvolatile content. It is. If the content is less than 0.01% by mass, the effect of the release agent is insufficient. If the content exceeds 6.0% by mass, repellency or the like occurs during multi-layer printability, which will be described later, and the printability tends to be reduced. When using a hydraulic transfer film, peeling tends to occur between the decorative layer and the curable resin layer.

  The printing ink or paint contains a colorant such as a pigment or a dye in addition to the base resin. The blending amount of the colorant may be appropriately determined according to the purpose of decoration, but is usually in the range of 1 to 50 parts by mass, more preferably in the range of 3 to 30 parts by mass.

  Examples of the colorant include carbon black as a black pigment; yellow lead, yellow lead, anthraquinone yellow, mineral fast yellow, titanium yellow; red pigments such as Bengala, cadmium red, quinacridone red, permanent red 4R, risol red, and pyrazolone. Red, Watching Red Calcium Salt, Lake Red D, Brilliant Carmine 6B, Eosin Lake; Blue Pigment, Bitumen, Cobalt Blue, Alkaline Blue Lake, Victoria Blue Lake, Phthalocyanine Blue, Metal-free Phthalocyanine Blue; Green Pigment, Chrome Green , Chromium oxide, pigment green B, malachite green lake; titanium white or the like can be used as a white pigment.

  The resin used for the decorative layer, that is, the printing ink or paint, may contain a plasticizer, a surfactant, an antioxidant, an ultraviolet absorber, a matting agent, a solvent, or the like, if necessary.

  The decoration layer can be formed by gravure printing, offset printing, screen printing, ink jet printing, and the like, and gravure printing is preferable because a high-quality image can be easily obtained. It is preferable that the dry film thickness of a decoration layer is 0.5-15 micrometers, More preferably, it is 1-7 micrometers.

  The organic solvent used for the printing ink or paint of the decorative layer is not particularly limited as long as it dissolves the printing ink or paint. For example, aromatic solvents such as toluene and xylene, ester solvents such as ethyl acetate and butyl acetate, Examples thereof include ether solvents such as dimethyl ether and diethyl ether, ketone solvents such as methyl ethyl ketone, and alcohol solvents such as methanol, ethanol and isopropanol. 20-80 mass parts is preferable with respect to 100 mass parts of printing ink or the whole coating material, and, as for the compounding quantity of an organic solvent, More preferably, it is 30-60 mass parts. When the blending amount is less than 20 parts by mass, the viscosity becomes high and workability is lowered, and the colorant is not sufficiently dispersed in the thermoplastic resin. On the other hand, if the blending amount of the organic solvent exceeds 80 parts by mass, it takes a long time for drying after printing, and the productivity is lowered.

  The dry film thickness of the decorative layer is preferably 0.5 to 15 μm, and more preferably 1 to 7 μm in order to enable good decorative properties and activation during hydraulic transfer. As long as the design and spreadability are not impaired, the anti-foaming agent, anti-settling agent, pigment dispersant, fluidity modifier, anti-blocking agent, antistatic agent, antioxidant, light stabilizer in the decorative layer Various conventional additives such as ultraviolet absorbers may be added.

(Swelling suppression layer)
If the film for hydraulic transfer of the present invention has a swelling suppression layer that is a resin layer containing fine particles A in the transfer layer, the swelling suppression effect that is the effect of the present invention is more preferable. The swelling suppression layer is usually laminated in the order of curable resin layer / swelling suppression layer, or in the order of curable resin layer / decoration layer / swelling suppression layer.
The fine particles A used for the swelling suppression layer are preferably inorganic fine powders. For example, when aiming at the effect of making use of the base, a medium ink to which inorganic extender pigments such as silica, talc and kaolin are added so as to be translucent is preferable.
Titanium oxide pigments are so-called white pigments that have the effect of concealing the base and white ink and white paint can be used as they are. Therefore, the case where the swelling suppression layer is provided so as to be the base of the decoration layer (when the curable resin layer / decoration layer / swelling suppression layer are laminated in this order) is particularly preferable. In this case, the titanium oxide pigment content is preferably 40 to 80% by mass.

  The swelling suppression layer used in the hydraulic transfer film of the present invention preferably contains 40% by mass or more of fine particles A. The content of the fine particles A may be appropriately determined according to the absorption amount of the organic solvent, but is preferably 40 to 80% by mass, more preferably 50 to 80% by mass, and still more preferably 60 to 80% by mass.

As in the case of the curable resin layer, the swelling suppression layer in the present invention swells when the decoration layer is activated by an organic solvent, and the design of the decoration layer expands or blurs color. Plays a role in preventing decline.
In order to obtain a sufficient swelling inhibiting effect on the decorative layer, the swelling inhibiting layer preferably has sufficient adhesion to the decorative layer. For this reason, it is preferable to use resin used by the decoration layer as resin used by a swelling suppression layer. At the time of activation, in order to suppress induction of delamination due to phase separation by an activator, the swelling suppression layer preferably contains 50% by mass or more of the resin used in the decoration layer, and 80% by mass. % Or more is more preferable. More preferably, the content is 90% by mass or more.

  Examples of the resin that is used in the decorative layer and is preferably used in the swelling suppression layer include polyurethane and polyester.

  Resins used for the swelling suppression layer include plasticizers, surfactants, matting agents, solvents, antifoaming agents, anti-settling agents, pigment dispersants, fluidity modifiers, antiblocking agents, if necessary. Various conventional additives such as antistatic agents, antioxidants, light stabilizers and ultraviolet absorbers may be added.

Furthermore, in order to adjust the peeling force between the swelling suppression layer and the peelable film, the swelling suppression layer may contain a release agent. The release agent to be used is not limited at all as long as it can be dispersed in the swelling suppression layer formed into an ink or paint, like the decorative layer, but it is preferable to use a fluorine compound or a silicone compound, and control the molecular weight or chemical structure. A silicone compound is particularly preferred because it is easy to do. Among silicone compounds, polyether-modified polysiloxanes and polysiloxane-polyether block copolymers can be suitably used.
The content of the silicone compound in the printing ink or paint is preferably 0.01% by mass or more and 6.0% by mass or less, more preferably 0.05% by mass or more and 4.0% by mass or less in the nonvolatile content. It is. If the content is less than 0.01% by mass, the effect of the release agent is insufficient. If the content exceeds 6.0% by mass, repellency or the like occurs during multi-layer printability, which will be described later, and the printability tends to be reduced. When using a hydraulic transfer film, peeling tends to occur between the decorative layer and the curable resin layer.

The swelling suppression layer can be formed by gravure printing, offset printing, screen printing, ink jet printing, or the like. Of these, gravure printing is preferred. The dry film thickness of the swelling suppression layer is preferably 0.1 to 10 μm, more preferably 0.2 to 7 μm, and still more preferably 0.3 to 4 μm. The swelling suppression layer is preferably a continuous film because of its function. However, when solid printing is performed by printing, if the gap between the solid printing plates is 100 μm or more, it is contained in the swelling suppression layer. The effect of the fine particles A is diminished, the screens are dispersed, and the handle is easily broken. Therefore, when the swelling suppression layer is formed by a method in which a gap between the printing plates is generated, the gap between the printing plates is preferably less than 100 μm, more preferably 50 μm or less, and 20 μm or less. Further preferred.
As the organic solvent used for the swelling suppression layer, the same solvents as those used for the printing ink or paint of the decorative layer can be used.

In the case where the decorative layer is a printed pattern, the pattern is composed of dots referred to as a plate and is not a complete continuous film. Therefore, the pattern of the decoration layer has a property of being easily enlarged upon activation. Therefore, when an activator is applied to the transfer layer, the pattern may stretch so that the handle can be broken. Therefore, a swelling suppression layer is provided between the curable resin layer and the decoration layer, and the pattern is reinforced by sandwiching the decoration layer with the swelling suppression layer, and the decoration layer is softened and activated by activation. This is preferable because both reproducibility can be achieved.
In such a transfer layer laminated in the order of curable resin layer / swelling suppression layer a / decoration layer / swelling suppression layer b, if the swelling suppression layer a does not have sufficient adhesion to the decoration layer, delamination may occur. Since it becomes easy to produce, it is preferable to use resin used by the decoration layer. During activation, in order to suppress the induction of delamination due to phase separation by an activator, the resin used in the decorative layer preferably contains 90% by mass or more, and contains 95% by mass or more. More preferably. More preferably, it is preferably 100% by mass, that is, a resin composition obtained by removing only the colorant component from the printing ink or paint in the decorative layer.
In addition, the swelling suppression layer a is a part which is on the upper layer of the decorative layer after being transferred and expresses the design of the hydraulic transfer body obtained together with the decorative layer. For this reason, the swelling suppression layer a does not necessarily need to be transparent, and may be transparent to translucent or further colored depending on the required characteristics of the hydraulic transfer body.

(Peelable film)
The hydraulic transfer film of the present invention may be produced by laminating on a peelable film, and may be used by peeling from the release film during hydraulic transfer.
An example of a method for producing a hydraulic transfer film having a release film is shown below.

The decorative layer and the swelling suppression layer are formed on the peelable film (A).
a) Peelable film (A) / swelling suppression layer / decoration layer
b) Peelable film (A) / decoration layer / swelling suppression layer
c) Peelable film (A) / swelling suppression layer a / decoration layer / swelling suppression layer b
The peelable film (A) coated or printed so as to have any of the above structure and the support film (B) laminated with a curable resin layer are bonded together by dry lamination (dry lamination method). can do. In that case, it is necessary that the decorative layer is fixed on the peelable film with such a peeling force that the decorative layer is not peeled off by the work or handling such as film feeding.

  For this reason, it is preferable to measure the peel force at the interface between the decorative layer or the swelling suppression layer and the peelable film and to select a preferable combination of the peelable film and the transfer layer. Further, if necessary, it is possible to further reduce the peeling force by further surface-treating the peelable film.

  Specifically, a film made of a material such as polypropylene, polyethylene, polyester, nylon, or polyvinyl chloride can be used as the peelable film, and the thickness is preferably 20 μm to 250 μm.

(Method for producing hydraulic transfer film)
Next, an example of the manufacturing method of the hydraulic transfer film of the present invention is shown below.
The method for producing a hydraulic transfer film of the present invention is a curable resin that can be cured by at least one of irradiation with active energy rays and heating on a support made of a water-soluble or water-swellable resin and activated with an organic solvent. A film (A) provided with a layer, and a film (B) provided with a hydrophobic decorative layer soluble in an organic solvent comprising a printing ink film or a paint film and a swelling suppression layer on a peelable film, It is preferable that the curable resin layer of (A) and the decorative layer or swelling suppression layer of the film (B) are stacked so as to face each other and bonded together by dry lamination (dry lamination method).

  When the fine particles A are added, the adhesive force between the film (A) and the film (B) is weakened, and peeling occurs at the interface between the curable resin layer and the decorative layer when peeling the peelable film. In the case where the adhesive force between the decorative layer and the curable resin layer is insufficient, an adhesive layer is provided to increase the adhesion to the decorative layer after providing a curable resin layer that forms a matte tone on the support film. It is preferable to provide it. As the adhesive layer, it is preferable to use a curable resin layer that does not contain a matting agent, or a resin layer obtained by removing a colorant from an ink layer or paint layer that is a decorative layer. At this time, the adhesive layer of the film (A) and the decorative layer of the film (B) are stacked so as to face each other and are bonded together by dry lamination (dry lamination method).

  When the transfer layer does not have a decorative layer and the transfer layer is composed of a curable resin layer, the film (A) having a curable resin layer on the support and the peelable film are converted into a curable film (A). The resin layer and the peelable film are stacked so as to face each other and are bonded together by dry lamination (dry lamination method).

  The production of the hydraulic transfer film of the present invention is preferably carried out using a dry laminator. That is, a support is attached to one feed roll (first feed roll) of a dry laminator, and a decorative layer and a swelling-inhibiting layer of a pattern are previously formed on a peelable film on the other feed roll (second feed roll). A film (B) printed with the above is mounted. An organic solvent solution of the curable resin is applied to the surface of the water-soluble or water-swellable resin layer of the support film fed from the first feed roll, and further dried by a drier to be curable resin on the support film. A film (A) in which a layer is formed is obtained. Next, the curable resin layer of the film (A) and the decorative layer or the swelling suppression layer (2) of the film (B) fed out from the second feeding roll are overlaid so as to face each other, and pasted with a thermocompression-bonding roll. The film for hydraulic transfer of the present invention is manufactured by being combined and wound on a winding roll.

  In order to apply the organic solvent solution of the curable resin to the support, slit reverse coater, die coater, comma coater, bar coater, knife coater, gravure coater, gravure reverse coater, micro gravure coater, flexo coater, blanket coater, A roll coater, an air knife coater or the like can be used.

  In addition, by using a support laminated on a peelable film, the coating or printing substrate is hardly affected by sagging and has good dimensional stability. The film thickness can be precisely controlled.

  The production of the film (B) having the decorative layer and the swelling suppression layer on the peelable film may be applied, but is preferably performed by printing. In particular, when printing a pattern, gravure printing, flexographic printing, offset printing or Silk printing is preferred. A decorative layer and a swelling suppression layer are applied or printed on the peelable film and then dried to obtain a film (B).

The decorative layer and the swelling suppression layer are
1. ) A method of applying or printing on a curable resin layer on a support,
Or
2. ) Hydraulic transfer film by a method of dry laminating a film (A) having a curable resin layer formed on a support film and a film (B) having a decorative layer and a swelling suppression layer on a peelable film (2) Can be laminated inside.

  1. In the case of coating or printing on the curable resin layer on the support), appropriateness for coating or printing such as wettability of the surface of the curable resin layer is required. In addition, when a decorative layer with a pattern is introduced by multi-layer printing using a gravure printing machine, the order is reversed from printing from a normal solid to a light or dark pattern. It becomes difficult to ensure the smoothness of the solid layer in close contact with the transfer body. Furthermore, in the printing process, a phenomenon in which the ink printed on the previous plate is taken on the subsequent plate, so-called reverse transition, is likely to occur.

  On the other hand, In the case where the decorative layer is formed on the release film in advance, it can be dealt with by ordinary printing, and the above problems do not occur. For this reason, 2. The method of laminating a film (B) having a decorative layer on a peelable film and a film (A) having a curable resin layer formed on a support film is preferred.

  In the step of bonding the film (A) provided with a curable resin layer on a support and the film (B) provided with a decorative layer on a peelable film, in general, a support film such as a PVA film is used. Since the heat resistance is low, and bonding at a temperature exceeding 130 ° C. tends to cause problems such as film shrinkage and laminating wrinkles, the film (A) is bonded by drying and heating and pressing. It is preferable to carry out in the temperature range of ° C, and more preferably in the temperature range of 40 to 100 ° C.

  In order to produce a hydraulic transfer film having only a curable resin layer using a dry laminator, the above curable resin is used until the production of a film (A) having a curable resin layer formed on a support film. This is the same as the production of a hydraulic transfer film having a layer and a decorative layer. Next, the curable resin layer of the produced film (A) and the peelable film fed from the second feeding roll are overlapped, bonded by a thermocompression-bonding roll, and wound on a winding roll, thereby curable resin. A hydraulic transfer film having only a layer is produced.

  The obtained film for hydraulic transfer of the present invention is wound around a roll and covered with light-shielding paper, and if stored in a dark place such as a warehouse, the curing reaction does not proceed unnecessarily, and the film is blocked during storage. It does not occur, it can be fed out from the roll at the time of water pressure transfer, it can transfer the water of a clear decorative layer, and has sufficient market distribution unless it is actively exposed to ultraviolet rays and sunlight. It is. The water pressure transfer film of the present invention can be subjected to water pressure transfer in the same manner as the water pressure transfer of a conventional water pressure transfer film.

(Method for producing hydraulic transfer body)
The hydraulic transfer body of the present invention is obtained by detaching the release film from the hydraulic transfer film of the present invention, then floating on the water with the transfer layer facing up and the support facing down, and activating the transfer layer with an organic solvent. (Activation may be performed before floating in water), the transfer layer is transferred to the transfer target, the support is removed, and then the curable resin layer of the transfer layer is irradiated with at least one of active energy ray irradiation and heating. It is obtained by curing.

Specifically, the hydraulic transfer film from which the peelable film has been peeled is floated on water in a water tank with the support film facing down, and the support film is dissolved or swollen with water.
Next, an organic solvent is applied or sprayed onto the transfer layer to activate the transfer layer including the decorative layer and the cured resin layer. The activation of the transfer layer with an organic solvent may be performed before the film is floated on water.
Next, the member to be transferred and the hydraulic transfer film are submerged in water while pressing the member to be transferred against the transfer layer, and the transfer layer is brought into close contact with the member to be transferred by water pressure and transferred.
Finally, the support film is removed from the transfer medium that has been removed from the water, and the cured resin layer of the transfer layer transferred to the transfer medium is cured by at least one of active energy ray irradiation and heating to be cured resin. A hydraulic transfer body having a layer or a cured resin layer and a decorative layer is obtained.

  The activation of the transfer layer with an organic solvent is such that when the transfer layer is transferred from the hydraulic transfer film to the transfer target, the transfer layer is softened and can sufficiently follow the three-dimensional curved surface of the transfer target. It only has to be done.

  The water in the water tank in the hydraulic transfer functions as a hydraulic medium that adheres the curable resin layer of the hydraulic transfer film or the curable resin layer and the decorative layer to the three-dimensional curved surface of the transfer object when transferring the transfer layer, The support film is swelled or dissolved. Specifically, water such as tap water, distilled water or ion exchange water may be used. Depending on the support film used, 10 salts of inorganic salts such as boric acid may be added to the water. % Or less, or 50% or less alcohol may be dissolved.

  The activator used in the present invention is an organic solvent that solubilizes the transfer layer, that is, the curable resin layer and the decorative layer (including the swelling suppression layer). As the activator used in the present invention, the same activator used for general hydraulic transfer can be used. Specifically, toluene, xylene, butyl cellosolve, butyl carbitol acetate, carbitol, carbitol acetate , Cellosolve acetate, methyl isobutyl ketone, ethyl acetate, isobutyl acetate, isobutyl alcohol, isopropyl alcohol, n-butanol, solfit acetate, and the like, and mixtures thereof.

  In order to improve the adhesion between the printing ink or paint and the molded product, this activator may contain some resin components. For example, adhesion may be increased by including 1 to 10% of an ink binder having a similar structure such as polyurethane, acrylic resin, or epoxy resin.

  After the transfer layer is hydraulically transferred to the transfer target, the support film is removed by dissolving or peeling with water and then dried. The support film is removed from the transfer target by dissolving or peeling the support film with a water flow in the same manner as in the conventional hydraulic transfer method.

  About the curable resin layer which consists of active energy ray curable resin, after drying a hydraulic transfer body, active energy ray irradiation is performed and the curable resin layer is hardened. If it is a curable resin layer which consists of a thermosetting resin, hardening of a curable resin layer can be performed with drying.

  It is preferable that the transfer layer is sufficiently adhered to the surface of the transfer object, and a primer layer is provided on the transfer object surface as necessary. As the resin forming the primer layer, a conventional resin can be used as the primer layer without particular limitation, and examples thereof include a urethane resin, an epoxy resin, and an acrylic resin. In addition, primer treatment is not necessary for a transfer medium composed of a resin component having high solvent absorbability such as ABS resin or SBS rubber having good adhesion. The material of the transfer object may be any of metal, plastic, wood, pulp mold, glass, etc., as long as the shape does not collapse even if it is submerged in water by applying a waterproof process as required. It is not limited.

(Hydraulic transfer body)
