Description

Hardcoat film for molding

The present invention relates to a hard coat film for molding which is excellent in surface hardness and scratch resistance and also excellent in moldability.

Conventionally, as a film for shaping | molding, polyvinyl chloride film is typical and the unstretched film which consists of polyester, polycarbonate, and acrylic resin with small environmental load by heat resistance of recent years, Furthermore, heat resistance and solvent resistance An excellent biaxially stretched polyester film or the like is used (see Patent Documents 1 to 10, for example).

For example, when mounting a molding film such as a name plate or building material member of a home appliance, automobile, or the like in contact with the outside, in order to prevent scratches, the surface hardness of the molding film is compensated for to improve scratch resistance. For this purpose, a hard coat layer is provided on the surface.

As a method of providing a hard coat layer to a molding film, a method of forming a hard coat layer by laminating by a pressure molding method, a vacuum molding method, or the like and then post-processing by a dipping method, a spray method or the like is generally used. However, in the above-described method, since the hard coat layer is laminated by sheet processing, there is a limit not only in the improvement of the production speed but also in the stability of the quality. Therefore, after providing a hard-coat layer to the film before shaping | molding by a roll-to-roll system, the molded object by the method of shaping | molding became required.

In the case of laminating the hard coat layer before molding, as a characteristic required for the hard coat layer, not only the surface hardness and scratch resistance similar to the method of installing the hard coat layer by post-processing after molding is required, The formability which can be followed to the deformation | transformation which becomes follows becomes essential. However, in the case of general hard coat resins, in order to satisfy the surface hardness, since the hard coat layer is too hard, there is no moldability, and cracks (breakage of the hard coat layer) are caused in the hard coat layer due to deformation during molding processing. There was a problem that occurred.

Therefore, a hard surface is obtained by laminating a flexible resin having a certain degree of surface hardness after curing, and forming a plurality of layers having a flexible surface layer and a strong surface hardness on a hard coat film having improved moldability or a substrate having a high surface hardness. Hard coat films having hardness and flexibility are proposed (Patent Documents 11 to 14).

However, the hard coat films proposed in Patent Literatures 11 and 13 have an appropriate surface hardness, but have only limited processing characteristics such as flexibility and punching in terms of moldability, and the hard coat films proposed in Patent Literature 12 have extensibility. Although the surface hardness was not satisfactory. In addition, in the hard coat film proposed in Patent Document 14, both the surface hardness and the moldability are attempted, but in some fields where a higher degree of formability and a higher degree of surface hardness are required, sufficient performance may not be exhibited. That is, the said patent document did not provide the hard coat film for shaping | molding which satisfy | fills the characteristic of both high surface hardness and high moldability simultaneously.

Hereinafter, the present invention will be described in detail.

(Substrate film)

In the present invention, the base film is not particularly limited, but has a formability. The moldability herein means that a molded article can be formed by molding processing such as mold molding, press molding, or vacuum molding. Specifically, in a portion locally extended by molding, the substrate film has a film stress characteristic capable of forming a molded article without breaking the base film even when a high stress occurs in part.

Examples of such a base film include plastic films or sheets such as polyester, acrylic, cellulose, polyethylene, polypropylene, polyolefin, polyvinyl chloride, polycarbonate, phenol, urethane, and the like. The thing which bonded two or more arbitrary types is mentioned. Preferably, it is a polyester film with a good balance of heat resistance and flexibility.

As a base film, the polyester film containing the co-polyester excellent in the moldability at the time of heat shaping | molding at low temperature or low pressure is preferable. The copolyester includes (a) an aromatic dicarboxylic acid component, a copolymerized polyester composed of ethylene glycol and a glycol component containing branched aliphatic glycols or alicyclic glycols, or (b) terephthalic acid and isophthalic acid. Co-polyester composed of an aromatic dicarboxylic acid component and a glycol component containing ethylene glycol is very suitable.

As said copolyester, when using the copolyester comprised from the aromatic dicarboxylic acid component, the ethylene glycol, and the glycol component containing branched aliphatic glycol or alicyclic glycol, as an aromatic dicarboxylic acid component, , Terephthalic acid, isophthalic acid, naphthalenedicarboxylic acid or ester-forming derivatives thereof are very suitable, and the amount of terephthalic acid and / or naphthalenedicarboxylic acid component relative to the total dicarboxylic acid component is 70 mol% or more, preferably At least 85 mol%, particularly preferably at least 95 mol%, most preferably 100 mol%.

In this invention, the polyester film containing a copolyester contains the copolyester component as a structural component of a film, and the following are illustrated as a specific aspect. (1) all of the base film being a copolyester, (2) containing copolyester as part of the constituent components of the base film (for example, copolyester, polyethylene terephthalate, polyethylene naphthalate, etc.). To a resin composition obtained by mixing different (homo) polyesters), and (3) the base film to be a multilayer of a polyester layer containing a copolyester and a polyester layer not containing a copolyester.

As for the said base film, a biaxially oriented film is especially preferable from a viewpoint of heat resistance and solvent resistance. Examples of the stretching method include a tubular stretching method, a simultaneous biaxial stretching method, a sequential biaxial stretching method, and the like, but a sequential biaxial stretching method is preferable in terms of planarity, dimensional stability, and thickness nonuniformity. For example, as a sequential biaxial stretching method in the case of using a polyester film as a base film, roll stretching is carried out in the longitudinal direction from 1.6 to 4.0 times at 50 ° C. or more and 110 ° C. or less in the longitudinal direction, and then after preheating in a tenter. And it can extend | stretch in the width direction from 1.2 times or more and 5.0 times or less at glass transition temperature of -40 degreeC or more and +65 degreeC or less of polyester. Furthermore, after biaxial stretching, the heat setting treatment can be performed at a temperature of -40 ° C or more and -10 ° C or less of the polyester melting point.

In order to provide handling property (for example, winding property after lamination), the base film used by this invention contains particle | grains in a film, and it is preferable to form protrusion on the film surface. Examples of the particles to be contained in the film include inorganic particles such as silica, kaolinite, talc, calcium carbonate, zeolite, and alumina, and heat resistant polymer particles such as acrylic, PMMA, nylon, polystyrene, polyester, and benzoguanamine formalin condensate. have. In terms of transparency, the content of particles in the film is preferably small, for example, preferably 1 ppm or more and 1000 ppm or less. Moreover, it is preferable to select the particle | grains whose refractive index and the resin used for transparency are close. Moreover, in order to provide various functions as needed, a film may contain a light resistant agent (ultraviolet-proof agent), a pigment | dye, an antistatic agent, etc.

In the case of printing the molding hard coat film, for example, on a surface on which the hard coat layer is not laminated, the total light transmittance of the base film is preferably 80% or more, and the haze is preferably 5% or less. When transparency of a base film is inferior, visibility when the printed layer is seen from the hard-coat layer side falls.

The base film used by this invention may be a single | mono layer film, and the composite film of two or more layers which laminated | stacked the surface layer and the center layer may be sufficient. In the case of the composite film, there is an advantage that the functions of the surface layer and the center layer can be independently designed. For example, by containing the particles only in the thin surface layer to form irregularities on the surface, while maintaining handling properties, substantially no particles are contained in the thick center layer, thereby further improving transparency as a whole composite film. have. Although the manufacturing method of the said composite film is not specifically limited, Taking productivity into consideration, the raw material of a surface layer and a center layer is extruded from an extruder, respectively, is introduce | transduced in one dice, and after obtaining an unstretched sheet, it orientates at least uniaxially. Lamination by a so-called coextrusion method is preferable.

Although the thickness of the base film used by this invention changes with raw materials, when using a polyester film, 35 micrometers or more are preferable and, as for a minimum, 50 micrometers or more are more preferable. On the other hand, the upper limit of the thickness is preferably 260 µm or less, and more preferably 200 µm or less. When the thickness is thin, not only the handling property is poor, but also when heated at the time of drying so that the residual solvent of the hard coat layer decreases, heat wrinkles occur in the film, and the flatness tends to be poor. On the other hand, when the thickness is thick, not only is there a problem in terms of cost, but also poor planarity due to the wound wound is likely to occur in the case of winding and storing in a roll shape.

(Middle layer)

Although the hard coat film for shaping | molding of this invention becomes the structure which laminated | stacked the hard-coat layer on one side of the base film, it is preferable to provide an intermediate | middle layer for the purpose of improving the adhesiveness of a base film and a hard-coat layer. Moreover, when particle | grains are not contained in a film in order to raise transparency of a base film, the handling property of a base film can be provided by providing the intermediate | middle layer containing particle | grains simultaneously at the time of film manufacture.

Examples of the resin constituting the intermediate layer include polyester resins, polyurethane resins, polyester urethane resins, acrylic resins, melamine resins, and mixed resins thereof, but have good adhesion to the base film and the hard coat layer. It is important to select so that it is preferable, and specifically, when resin which comprises a base film and a hard-coat layer is acrylic type, it is preferable to select 1 or more types of an acryl-type, co-polyester type, and polyester urethane type.

In the said intermediate | middle layer, you may form a crosslinked structure by containing a crosslinking agent for the purpose of improving adhesiveness and water resistance. Examples of the crosslinking agent include urea, epoxy, melamine and isocyanate. In addition, you may use graft copolymer resin which has self-crosslinkability as resin, without using a crosslinking agent.

The intermediate layer may contain various particles for the purpose of improving the activity by forming irregularities on the surface of the film before the hard coat layer is formed. As particles to be contained in the intermediate layer, for example, inorganic particles such as silica, kaolinite, talc, calcium carbonate, zeolite and alumina, organic particles such as acrylic, PMMA, nylon, styrene, polyester, and benzoguanamine formalin condensate Can be mentioned. Moreover, it is preferable to select the particle | grains whose refractive index and the resin used for transparency are close.

As a method of providing the intermediate layer, a coating method is preferable. As a coating method, it uses a well-known coating method, such as a gravure coat method, a kiss coat method, a dip method, a spray coat method, a curtain coat method, an air knife coat method, a blade coat method, a reverse roll coating method, in a film manufacturing process. It can install by the in-line coat system which installs a coating layer, and the offline coat system which installs a coating layer after film manufacture. Among these methods, the inline coating method is not only excellent in terms of cost, but also by including the particles in the intermediate layer, it is not necessary to contain the particles in the base film, and thus the transparency can be highly improved, which is preferable.

(Hard coat layer)

In the hard coat film for shaping | molding of this invention, a hard coat layer is laminated | stacked on at least single side | surface of a base film directly or via an intermediate | middle layer. In the present invention, the hard coat layer has a film having a higher hardness than the substrate and can follow the deformation during molding in order to supplement the surface hardness of the substrate serving as the substrate film and to improve scratch resistance. The layer which has is shown. More specifically, the molding hard coat film of the present invention has a pencil hardness of at least H or more as surface hardness, and has an elongation of at least 10% or more by an evaluation method described later, for example, for nameplates or building materials such as home appliances. It can be used suitably as a member.

The hard coat layer which can be used by this invention needs to have ionizing radiation hardening type resin as a main component. It does not need to heat-process at the time of hardening like a thermosetting resin, and can reduce the thermal contraction of the base film by heat, and is very suitable. In the present invention, the ionizing radiation curable compound refers to a compound that polymerizes and / or reacts by irradiating any one of electron beams, radiation, and ultraviolet rays, and such a compound polymerizes and / or reacts to form a hard coat layer. Examples of the ionizing radiation curable compound used in the present invention include, but are not limited to, melamine type, acrylic type, and silicone type ionizing radiation curable compounds. Among these, an acrylate ionizing radiation curable compound is preferable in terms of obtaining high surface hardness.

In addition, in the present invention, the ionizing radiation curable compound includes not only monomers and precursors but also ionizing radiation curable resins in which they are polymerized and / or reacted. For example, examples of the acrylate-type ionizing radiation curable compound include, but are not particularly limited to, polyurethane acrylate, polyester acrylate, epoxy acrylate, polyol acrylate, and any acrylate-type ionizing radiation curable compound. You can also use

The hard coat layer in this invention is an electron beam, a radiation, an ultraviolet-ray, after apply | coating to the base film the coating liquid containing at least an ionizing radiation curable compound which has 3 or more functional groups, and a 1 and / or bifunctional ionizing radiation curable compound.

When using an acrylate ionizing radiation curable compound as an ionizing radiation curable compound, As a trifunctional or more acrylate ionizing radiation hardening compound in this invention, (a) Specifically, pentaerythritol tri (meth) acrylate, Pentaerythritol tetra (meth) acrylate, dipentaerythritol tri (meth) acrylate, dipentaerythritol tetra (meth) acrylate, dipentaerythritol penta (meth) acrylate, dipentaerythritol hexa (meth) acrylate, trimethyl Obtained by reacting an alcoholic hydroxyl group containing (meth) acrylate with the terminal isocyanate group containing compound obtained by making (b) polyhydric isocyanate compound and two or more alcoholic hydroxyl group containing compounds react previously, such as all propane tri (meth) acrylate 3 or more in the molecule Three or more (meth) acryloyl jade in the molecule | numerator obtained by making acrylic acid or methacrylic acid react with the urethane (meth) acrylate which has a (meth) acryloyloxy group, and (c) the compound which has three or more epoxy groups in a molecule | numerator Epoxy (meth) acrylates which have timing can be mentioned.

In the present invention, it is important that the ionizing radiation curable compound contained in the coating liquid contains at least one trifunctional or more ionizing radiation curable compound in addition to the monofunctional or bifunctional ionizing radiation curable compound. In the hard coat layer after curing, a trifunctional or higher trifunctional ionizing radiation curable compound component is a hard segment, in which a monofunctional and / or bifunctional ionizing radiation curable compound reacts, and the monofunctional and / or bifunctional The ionizing radiation curable compound component is present as a soft segment. Thus, by adjusting two or more kinds of ionizing radiation curable compounds having different functional numbers to specific concentration ranges, hetero-crosslinked structures are introduced into the hard coat layer, and surface hardness and scratch resistance are imparted by the hard segments, and the soft segments By the elasticity, the remarkable effect of achieving the yield-breaking property of providing moldability was obtained.

In the present invention, 1 and / or bifunctional ionizing radiation curable type in the ionizing radiation curable compound contained in the coating liquid in order to achieve high surface hardness and excellent moldability, specifically, pencil hardness of H or higher and elongation of 10% or more. It is important that content of a compound is 5 mass% or more and 95 mass% or less. When the content is less than 5% by mass, not only the flexibility of the film is lowered but also cracks occur in the hard coat layer during molding, which is not preferable. Moreover, when the said content exceeds 95 mass%, the hardened film which has sufficient surface hardness and abrasion resistance is hard to be obtained. 10 mass% or more is more preferable, and, as for the minimum of the said content, 20 mass% or more is more preferable. Moreover, 90 mass% or less is more preferable, as for the upper limit of the said content, 80 mass% or less is more preferable, and 70 mass% or less is still more preferable. When the content of the 1 and / or bifunctional ionizing radiation curable compound in the ionizing radiation curable compound is 20% by mass or more and 80% by mass or less, both surface hardness and moldability are more highly achieved, and specifically, pencil hardness of 2H or more Elongation of 20% or more can be achieved, and it is very suitable for molding films requiring high hardness and high processability at the same time, for example, nameplates for automobiles and housings for portable devices.

In addition to the above aspect, the present inventors have found that by using an ionizing radiation curing compound having an amino group as the ionizing radiation curing compound, surface hardness and moldability can be more highly compatible. That is, it is preferable that the 1 or more types of ionizing radiation hardening compounds contained in the said coating liquid have an amino group. The said effect by using the compound which has an amino group as an ionizing radiation hardening compound can be considered as follows. When there is a difference in partial hardness distribution in the hard coat layer, when the hard coat layer is stretched, cracks are likely to occur locally. As a factor of the difference in such partial hardness distribution, there is a polymerization inhibition (oxygen inhibition) of the ionizing radiation cured resin by oxygen. Here, in the case of using a compound having an amino group as the ionizing radiation curing compound, since the amino group traps radical oxygen and the effect of oxygen inhibition on the hardening layer surface layer portion hardening reaction is reduced, a uniform curing reaction is performed throughout the layer. Proceed. As a result, the stress applied to the hard coat layer at the time of molding is dispersed throughout the layer, and the occurrence of cracks at the time of molding is suppressed. Therefore, it is thought that both surface hardness and moldability can be achieved more highly. In addition to the above effects, by containing an amino group as the ionizing radiation curable resin, the hardening effect on the surface of the hard coat layer is more accelerated by hardening of the surface of the hard coat layer as compared with the case where no amino group is contained, thereby improving the surface hardness. Can be.

It is preferable that content of the ionizing radiation curable compound containing an amino group in the ionizing radiation curable compound contained in the said coating liquid is 2.5 mass% or more and 95 mass% or less. As for the minimum of content of the ionizing radiation curable compound containing an amino group in the ionizing radiation curable compound contained in the said coating liquid, it is more preferable that it is 5 mass% or more, and it is still more preferable that it is 10 mass% or more. Moreover, it is more preferable that the upper limit of the said content is 92.5 mass% or less, It is more preferable that it is 90 mass% or less, It is still more preferable that it is 50 mass% or less. When the content of the ionizing radiation curable compound containing an amino group in the ionizing radiation curable compound contained in the coating liquid is less than 2.5% by mass, it is difficult to uniformly harden the entire hard coat layer, so that resistance to cracks during molding is obtained. It becomes hard to lose. When the ionizing radiation-curable compound containing an amino group has a high concentration, yellowing of the hard coat layer becomes stronger due to the amino group, so that when the content exceeds 95% by mass, high transparency may be impaired. For example, when performing a printing process on the surface which does not laminate | stack a hard coat layer, it is preferable that it is 2 or less as a color b value of a film, and in this case, it is preferable that the ionizing radiation curable compound containing an amino group is 92.5 mass% or less. desirable.

In the present invention, the coating liquid includes an ionizing radiation curable compound having a 1 and / or bifunctional ionizing radiation curable compound, and an ionizing radiation curable compound having three or more functional groups. In the above embodiment, some of the ionizing radiation curable compounds include What is necessary is just to contain an amino group. Moreover, it is a preferable embodiment that either the monofunctional ionizing radiation curable compound, the bifunctional ionizing radiation curable compound, or the ionizing radiation curable compound which has 3 or more functional groups is an ionizing radiation curable compound containing an amino group.

When using an acrylate ionizing radiation curable compound as an ionizing radiation curable compound having an amino group, for example, as an acrylate ionizing radiation curable compound having an amino group, acrylamide, 7-amino-3,7-dimethyloctyl ( Meta) acrylate, isobutoxymethyl (meth) acrylamide, t-octyl (meth) acrylamide, diacetone (meth) acrylamide, dimethylaminoethyl (meth) acrylate, diethylaminoethyl (meth) acrylate, N, N-dimethyl (meth) acrylamide tetrachlorophenyl (meth) acrylate, N-vinylformamide, etc. are mentioned.

In addition to the above aspect, the inventors of the present invention have found that by containing the particles in the hard coat layer, the moldability is further improved, and further, both the surface hardness and the moldability can be achieved. The effect | action which moldability improves by containing particle | grains in a hard-coat layer is considered as follows. When the hardness of the hard coat layer rises, at the time of molding, a strong stress is generated temporarily in the hard coat layer with high hardness, thereby causing cracks (cracks) in the hard coat layer at once. Herein, the particles present in the hard coat layer alleviate the internal stress applied to the hard coat layer at the time of molding at the interface between the ionizing radiation curable compound and the particles, thereby suppressing the occurrence of cracks and improving the appearance of the hard coat layer. It is thought that there is an effect that a small crack which cannot be confirmed with the naked eye not to be damaged is preceded, the fatal cracking of the hard coat layer is delayed, and as a result, the effect of improving moldability is expressed.

As the particles to be contained in the hard coat layer, for example, amorphous silica, crystalline silica, silica-alumina composite oxide, kaolinite, talc, calcium carbonate (calcite type, bariterite type), zeolite, alumina, hydroxy apatite Inorganic particles, crosslinked acrylic particles, crosslinked PMMA particles, crosslinked polystyrene particles, nylon particles, polyester particles, benzoguanamine formalin condensate particles, benzoguanamine melamine formaldehyde condensate particles, melamine formaldehyde condensate Although organic-inorganic hybrid microparticles | fine-particles, such as heat resistant polymer particle | grains, such as a particle | grain, and a silica acryl composite compound, are mentioned, In the present invention, the kind of particle | grains is not specifically limited.

Examples of the shape of the particles include spherical, blocky, plate-like, fibrous, or flake-shaped, but are not particularly limited, and among them, spherical particles are dropped in contact with dispersibility or other members. Particles are preferred.

In this invention, it is preferable that the average particle diameter of particle | grains is 10 nm or more and 300 nm or less, Furthermore, it is preferable that a minimum is 40 nm or more and an upper limit is 200 nm or less, Especially it is preferable that a minimum is 50 nm or more and an upper limit is 100 nm or less. . When the average particle diameter of the particles is smaller than 10 nm, the average particle diameter is too small, so that the effect of improving the surface hardness, scratch resistance, and moldability due to the particle addition described above, or one of them, may be less. Moreover, when it exceeds 300 nm, a hard coat layer may become weak and moldability may fall. In addition, said average particle diameter is the average particle diameter measured by disperse | distributing the particle | grains by the catalyst which does not swell using a Coulter counter (made by Beckman Coulter, Multisizer II type).

When content of particle | grains is less than 5 mass%, all the improvement effects of surface hardness, abrasion resistance, and moldability by the particle addition mentioned above, or any one may be reduced. On the other hand, when content of particle | grains exceeds 70 mass%, the above-mentioned micro cracks generate | occur | produce abundantly at the time of shaping | molding, haze rises (whitening), and the transparency of a molded object is impaired.

In addition to the above aspects, the inventors of the present invention have found that by containing an ionizing radiation curable silicone resin in the hard coat layer, activity is imparted, surface scratch resistance is improved, and surface hardness and moldability are highly compatible. . In this aspect, the ionizing radiation curable silicone resin itself crosslinks by a curing reaction, and in some cases, also crosslinks with the ionizing radiation curable resin constituting the hard coat layer.

It is preferable to mix | blend 0.3-13 mass parts, More preferably, 0.5-5 mass parts. When the compounding quantity of an ionizing radiation curable silicone resin is less than a lower limit, the effect of improving the scratch resistance at the time of forming a molded body is inferior, and when the upper limit is exceeded, curing may not be sufficiently performed at the time of hard coat layer formation. In addition, 1 type of ionizing radiation hardening type silicone resins to be contained in a hard-coat layer may be used, and may be used in combination of 2 or more type.

As for the addition amount of a photoinitiator, 0.01 mass part or more and 15 mass parts or less per 100 mass parts of ionizing radiation curable compounds contained in the said coating liquid are suitable, and when the usage-amount is small, reaction will become slow and productivity will become poor, and it will remain unsatisfactory Sufficient surface hardness and scratch resistance are not obtained by the reactant. On the contrary, when there is much addition amount, the problem that a hard coat layer yellows with a photoinitiator arises.

In the present invention, a known heat polymerization inhibitor such as hydroquinone, hydroquinone monomethyl ether, 2,5-t-butylhydroquinone, is added to the coating liquid in order to prevent thermal polymerization during production or dark reaction during storage. It is desirable to.

It is preferable to make content of surfactant into 0.01 mass% or more with respect to the coating liquid which comprises a hard-coat layer from an improvement of an application | coating appearance and an activity. On the other hand, since surfactant bleeds out on the surface of a hard-coat layer and contaminates what touched the hard-coat layer, it is preferable to make content of surfactant into 2.00 mass% or less.

Moreover, it is preferable that HLB is 2 or more and 12 or less of surfactant to be used. By using surfactant whose HLB is 2 or more, leveling property by surfactant activity can be improved. The HLB of the surfactant is more preferably 3 or more, particularly preferably 4 or more. On the other hand, deterioration of activity can be suppressed by using surfactant whose HLB is 12 or less.

The lower the HLB value, the higher the lipophilicity, while the higher the HLB value, the higher the hydrophilicity.

Various additives can be mix | blended with the hard coat layer of this invention as needed. For example, a fluorine- or silicon-based compound for imparting water repellency, an antifoaming agent for improving coating properties and appearance, and further, an antistatic agent and a dye or pigment for coloring.

In the present invention, the hard coat layer is preferably formed by curing the coating liquid containing an ionizing radiation curable compound, particles, a photopolymerization initiator, and a surfactant on the base film after application drying in an organic solvent.

A well-known method is mentioned as a method of laminating | stacking a hard-coat layer, The method of hardening after apply | coating drying the said coating liquid on a base film is preferable. As a coating method, well-known coating methods, such as a gravure coat method, a kiss coat method, a dip method, a spray coat method, a curtain coat method, an air knife coat method, a blade coat method, a reverse roll coating method, a bar coat method, a lip coating method, etc. Can be mentioned. Among these, the gravure coat method which can be coated by a roll-to-roll method and can apply | coat uniformly, especially the reverse gravure method are preferable.

As a method of dissolving or dispersing an ionizing radiation curable compound, particles, a photopolymerization initiator, and the like contained in the coating liquid in an organic solvent, a method of stirring and dispersing them under heating is very suitable. By heating a coating liquid, the solubility of an ionizing radiation curable compound, particle | grains, and a photoinitiator can be improved. Therefore, deterioration of the coating appearance by an unsealed seafood etc. can be suppressed.

A well-known thing can be used for a disperser. Specifically, ball mill, sand mill, attritor, roll mill, agitator, colloid mill, ultrasonic homogenizer, homo mixer, pearl mill, wet jet mill, paint shaker, butterfly mixer, planetary mixer, Henschel mixer, etc. Can be mentioned.

As for the density | concentration of solid content, such as an ionizing radiation curable compound, particle | grains, a photoinitiator, contained in the said coating liquid, 5 mass% or more and 70 mass% are preferable. By adjusting the density | concentration of solid content of a coating liquid to 5 mass% or more, the fall of productivity by the drying time after application | coating can be suppressed. On the other hand, by adjusting the density | concentration of solid content of a coating liquid to 70 mass% or less, deterioration of the leveling property by raise of the viscosity of a coating liquid, and deterioration of the coating appearance accompanying it can be prevented. Moreover, it is preferable to adjust a compounding quantity in the solid content concentration of a coating liquid, the kind of organic solvent, and the kind of surfactant so that the viscosity of a coating liquid may be in the range of 0.5 cps or more and 300 cps or less from a viewpoint of an application appearance.

Although the thickness of the hard-coat layer after application | coating and hardening depends on the extent of elongation at the time of shaping | molding, it is preferable to make it the thickness of the hard-coat layer after shaping | molding become 0.5 micrometer or more and 50 micrometers or less. Specifically, the lower limit of the thickness of the hard coat layer before molding is preferably 0.6 µm or more, and more preferably 1.0 µm or more. The upper limit of the thickness of the hard coat layer before molding is preferably 100 µm or less, more preferably 80 µm or less, still more preferably 60 µm or less, and even more preferably 20 µm or less. When the thickness of the hard coat layer is thinner than 0.6 mu m, hard coatability is hardly obtained. On the contrary, when the thickness of the hard coat layer exceeds 100 mu m, curling due to poor curing or shrinkage of the hard coat layer shows a tendency.

When pre-drying is required, such as when an organic solvent is blended in the coating liquid, a known hot air drying, an infrared heater, or the like may be used as a method of applying and drying on a base film, but hot air drying with a high drying speed is preferable. Do.

It is preferable to perform the drying temperature after application | coating on the conditions of 40 degreeC or more and 120 degrees C or less, and especially a minimum of 45 degreeC or more and an upper limit of 80 degrees C or less are preferable. If it is less than 40 degreeC, not only the organic solvent contained in a coating liquid cannot be removed sufficiently, but problems, such as brushing, may arise. On the contrary, at the temperature exceeding 120 degreeC, the micro faults of coating films, such as a micro coat | film | coat derived from foam, micro frying, and a crack, tend to generate | occur | produce, and an external appearance may become bad. Furthermore, since the film is strongly contracted by heat and the planarity of the film is deteriorated by heat wrinkles, uniform elongation is not obtained at the time of molding, or local elongation occurs and the film is broken. The castle is poor.

The tension of the film applied during drying is preferably 50 N / m or more and 300 N / m or less, particularly preferably 100 N / m or more and 250 N / m or less. When the tension of the film is less than 50 N / m, the running film becomes meandering, and it is impossible to coat the coating liquid. On the contrary, when it exceeds 300 N / m, wrinkles generate | occur | produce in a film, deterioration of planarity, and the appearance of the wound film worsen. Furthermore, when a base film is excellent in moldability at low temperature, it extends | stretches in the advancing direction of a film during drying, a width direction shrinks, and at worst, a problem arises in productivity, such as being broken.

In the present invention, pigments such as a hard coat layer, an antistatic layer, an easily adhesive layer, an adhesive layer, an active layer, an electromagnetic wave absorbing layer, a dye or a pigment, etc. may be added to the surface on which the hard coat layer is not provided so as not to impair the effects of the present invention.

In this invention, a hard coat layer is formed by irradiating an ultraviolet-ray to a coating liquid. As accumulated light quantity to irradiate, Preferably it is 50 mJ / cm <2> or more and 1000 mJ / cm <2> or less, More preferably, a minimum is 300 mJ / cm <2> or more and an upper limit is 700 mJ / cm <2> or less. Moreover, when irradiating, it is preferable to carry out in nitrogen gas atmosphere because oxygen inhibition is reduced and scratch resistance improves. When the accumulated light amount is less than 50 mJ / cm 2, the polymerization reaction of the ionizing radiation curable compound is not promoted, and the surface hardness of the hard coat layer is significantly lowered. When accumulated light amount exceeds 1000 mJ / cm <2>, a base film may deform | transform under influence of a heat. In addition, the accumulated light amount in this invention can be measured by "UVR-T35" made by TOPCON.

In addition, when hardening | curing a coating liquid with an electron beam, 5 kGy or more and 100 kGy or less are preferable, and, as for an irradiation dose, an upper limit is more preferably 30 kGy or more, and a lower limit is more preferably 70 kGy or less. When it is less than 5 kGy, the polymerization reaction of the ionizing radiation curable compound is not promoted, and the surface hardness of the hard coat layer is significantly lowered. When it exceeds 100 kGy, the lifetime fall of an electron beam irradiation tube is remarkable, and it is unpreferable from a production cost point of view.

The hard coat film for shaping | molding of this invention is a film excellent in the surface hardness. Specifically, in the case of a hard coat film for molding using a biaxially oriented polyester film containing a copolyester as a base film, although it varies depending on the base film, it is preferable that the measured value of pencil hardness is not less than H, and more than 2H. Is particularly preferred. Evaluation of the pencil hardness was performed here based on JIS-K5600.

Specifically, although it varies depending on the base film, in the case of a hard coat film for molding using a biaxially oriented polyester film containing a copolyester as the base film, the elongation is 10% when the room temperature and the film actual temperature are 160 ° C. It is preferable that it is the above, It is more preferable that it is 20% or more, It is especially preferable that it is 30% or more. Here, elongation is when the hard coat film for shaping | molding is cut out in rectangular shape of length 10mm and width 150mm, and it pulls, respectively, when film actual temperature is 160 degreeC, When a crack or whitening generate | occur | produces in a hardcoat layer The elongation of was set as the elongation (%).

As a method of adjusting moldability (elongation), content of the 1 or bifunctional ionizing radiation curable compound in an ionizing radiation curable compound contained in the coating liquid which forms a hard-coat layer, content of the ionizing radiation curable compound which has an amino group, and hard It can change with the amount of particle | grains in a coat layer.

When the hard coat film for shaping | molding of this invention performs a printing process to the surface which does not laminate | stack a hard coat layer, it is preferable that there exists transparency. Although it changes with a base film specifically, in the case of the hard-coat film for shaping | molding which used the biaxially-oriented polyester film containing co-polyester as a base film, it is preferable that haze is 5% or less. As a method of adjusting a haze, it can change according to the amount of particle | grains in a hard-coat layer.

When the hard coat film for shaping | molding of this invention performs a printing process to the surface which does not laminate | stack a hard coat layer, it is preferable that there is no coloring. Although it changes with a base film specifically, in the case of the hard-coat film for shaping | molding which used the biaxially-oriented polyester film containing co-polyester as a base film, it is preferable that the value of color tone b * is 2.0 or less.

(Hard Coat Film Roll for Molding)

The shaping | molding hard coat film roll of this invention is obtained through the process of winding up a long shaping | molding hard coat film in a cylindrical core continuously in roll form. By using the molding hard coat film roll, productivity at the time of processing can be improved and it can further contribute to the stability of the quality of a molded object. Although the length of the shaping | molding hard coat film roll which wound the elongate shaping | molding hard coat film in the roll form continuously on a cylindrical core is not specifically limited depending on a use, It is preferable that it is 50 m or more and 5000 m or less, It is preferable that it is 100 m or more and 3000 m or less. The following is more preferable. In the case where the recommendation is short, the frequency of switching of the hard coat film for molding during the printing layer processing in a later step becomes high, for example, and the workability deteriorates. On the contrary, when the recommendation is long, the molding hard coat film expands and contracts due to the external environmental temperature, and a winding body is generated, resulting in a poor appearance of the core part.

Although the width | variety of the hard-coat film roll for shaping | molding differs according to a use, it does not specifically limit, From a viewpoint of workability, 100 mm or more and 2000 mm or less are preferable, 500 mm or more and 1500 mm or less are more preferable.

As for the cylindrical core which wraps the hard coat film for shaping | molding, a plastic core is preferable. In the case of using a paper core generally used, equity or the like is generated and adheres to the hard coat layer, which tends to be defective. As a plastic core, a well-known thing can be used suitably suitably, A polypropylene core and a FRP core are preferable at the point of strength. The size of the cylindrical core is preferably 3 inches or more and 6 inches or less in diameter. In the case of using a core having a small diameter, a wound wound around the core portion occurs, and the handleability in a later step is poor. On the other hand, when a diameter is large, a roll diameter becomes large and handling property becomes bad.

In order to wind a hard coat film for shaping | molding to a core, it is preferable to start winding after fixing a hard coat film for shaping | molding to a core via double-sided tape. When the double-sided tape is not used, it does not wind straight during the winding or the warp is likely to occur during transportation. Although a well-known thing can be used as a double-sided tape, it is preferable to have an adhesion layer on both surfaces of a plastic film from the viewpoint of generation | occurrence | production of a stake and a strength. As for the thickness of a double-sided tape, 5 micrometers or more and 50 micrometers or less are preferable. When it is thin, strength falls and workability worsens, and the fixing force of a film falls. On the contrary, when it is thick, the flatness of the hard coat film for shaping of a core part becomes poor by the step | step by a tape.

In this invention, it is preferable to provide an unevenness | corrugation (emboss) to the both ends of the width direction of a hard coat film for shaping | molding. By providing unevenness, it becomes difficult to leave traces by the double-sided tape of the core portion, and at the point of contacting the hard coat layer and the base film surface layer on the opposite side, or the layer imparted with the above-mentioned functionality laminated on the base film. Falls and the storage stability in roll form becomes favorable. 10 micrometers is preferable and, as for the minimum of the height of unevenness | corrugation, More preferably, it is 15 micrometers. On the other hand, 40 micrometers is preferable and, as for the upper limit of the height of unevenness, More preferably, it is 35 micrometers. If the height of the unevenness is too low, the effect of improving the storage stability in the roll form due to the unevenness is small. On the other hand, when the height of the unevenness is too high, the skew or the like easily occurs during transportation. As a method of providing unevenness, a known method can be used. Specifically, the method of pressing down the metal roll with a processus | protrusion on the surface, and providing an unevenness | corrugation is mentioned. In addition, it is preferable to apply concavo-convex processing to a base film beforehand, before forming a hard-coat layer on a base film.

(Molded article)

The hard coat film for molding of the present invention is molded using a molding method such as vacuum molding, pressure molding, mold molding, press molding, laminate molding, in-mold molding, drawing molding, bending molding, or stretching molding.

0.5 micrometer or more and 50 micrometers or less are preferable, and, as for the thickness of the hard coat layer of the molded object formed by shape | molding said hard coat film for shaping | molding, 0.5 micrometer or more and 10 micrometers or less are especially preferable. When the thickness of the hard coat layer of the molded body is thinner than 0.5 μm, hard coat property is not obtained or when heat is applied to the molded body in terms of heat resistance, the surface of the hard coat layer may be wavy because it cannot follow the shrinkage of the base film. It becomes rough and damages an external appearance. On the contrary, when it exceeds 50 micrometers, there is no phase difference in the surface hardness in the more hard coat layer thickness, and the advantage becomes small in a quality viewpoint.

Since the molded article thus formed has a hard coat layer to compensate for surface hardness, it is mounted at a position in contact with the outside, and a name plate for a home appliance, an automobile name plate, a dummy can, a building material, and a decorative plate that require scratch resistance It can be used suitably as a molding member, such as a makeup steel plate and a transfer sheet.

The film width length was measured after apply | coating-curing to the base film of 1000 mm in width and 200 m in length, and providing a hard-coat layer. When a film width length before coating and a film width length after coating were made into b, the shrinkage rate (width shrinkage rate) of the film width direction before and behind coating was calculated | required by the following formula. When the widthwise shrinkage was 1.5% or less, it was good, and when it exceeded 1.5%, it was judged as bad.

Widthwise shrinkage (%) = (a-b) x 100 / a
