Description

  The present invention relates to a molding hard coat film having excellent surface hardness and scratch resistance and excellent moldability.

  Conventionally, as a film for molding, a polyvinyl chloride film has been representative, and due to recent needs for environmental resistance, unstretched films made of polyester, polycarbonate and acrylic resin, which have a low environmental load, and further heat resistance and resistance. A biaxially stretched polyester film having excellent solvent properties is used. (For example, see Patent Documents 1 to 10).

  For example, when a molding film is attached to a position where it touches the outside, such as a home appliance, a car nameplate or a building material member, in order to prevent scratches, the surface hardness of the molding film is supplemented and the scratch resistance is improved. A hard coat layer is provided on the surface.

  As a method for providing a hard coat layer on a molding film, a method is generally employed in which a hard coat layer is laminated after being molded by a pressure forming method, a vacuum forming method, or the like and then post-processed by a dipping method, a spray method or the like. However, in the above-described method, the hard coat layer is laminated by single-wafer processing, so that there is a limit to improvement in production speed and there is a problem in stability of quality. Therefore, after a hard coat layer is provided on a film before molding by a roll-to-roll method, a molded body by a method of molding is required.

  In the case of a method of laminating a hard coat layer before molding, as the characteristics required for the hard coat layer, surface hardness and scratch resistance comparable to the method of providing a hard coat layer in post-processing after molding are required, Formability that can follow the deformation accompanying molding is essential. However, in the case of a general hard coat resin, since the hard coat layer is too hard to satisfy the surface hardness, there is no moldability and cracks in the hard coat layer due to deformation during molding (cracking of the hard coat layer) There was a problem that occurred.

  Therefore, a hard coat film in which a flexible resin is laminated while having a certain degree of surface hardness after curing to improve moldability, and a layer having a flexible surface and a strong surface hardness on the substrate A hard coat film having strong surface hardness and flexibility has been proposed by laminating a plurality of layers (Patent Documents 11 to 14).

Japanese Patent Laid-Open No. 9-156267 JP-A-9-187903 JP-A-10-296937 JP-A-11-268215 JP 2001-129951 A JP 2001-212868 A JP 2002-249652 A JP 2003-221606 A Japanese Patent Laid-Open No. 2004-075713 JP-A-2005-290354 JP 2005-305383 A JP 2007-284626 A JP 2007-313728 A International Publication No. 2008/029666 Pamphlet

  However, although the hard coat film proposed in Patent Documents 11 and 13 has an appropriate surface hardness, the hard coat film has only limited processing characteristics such as bendability and punching, and is proposed in Patent Document 12. Although the hard coat film has extensibility, the surface hardness was not satisfactory. In addition, although the hard coat film proposed in Patent Document 14 attempts to achieve both surface hardness and formability, it has sufficient performance in fields where higher formability and higher surface hardness are required. In some cases, it could not be demonstrated. That is, the above-mentioned patent document does not provide a hard coat film for molding that satisfies both high surface hardness and high moldability at the same time.

  In addition, with the advancement of mobile technology, hard coat films have come to be used as the outer surface of equipment used outdoors. Under such circumstances, the base film is likely to be deteriorated by sunlight. Therefore, excellent light resistance has been demanded as a hard coat film for molding.

  The object of the present invention is to solve the above problems, that is, by producing and processing a hard coat layer on a molding film before easy molding while having excellent light resistance. An object of the present invention is to provide a molding hard coat film that can contribute to improving the stability of quality and quality, and has both surface hardness, scratch resistance and moldability that can follow deformation during molding.

  As a result of intensive studies to solve the above problems, the present inventors have finally completed the present invention. That is, the present invention is as follows.

  The molding hard coat film of the present invention has excellent light resistance and has characteristics of both surface hardness, scratch resistance and moldability that can follow deformation during molding. Since the present invention has a high surface hardness and excellent extensibility, it can be suitably used as, for example, a nameplate member or a building material member as a preferred embodiment. Further, as a preferred embodiment of the present invention, when an ionizing radiation curable resin or / and particles having an amino group are used, both characteristics of surface hardness and moldability can be achieved at a higher level. For example, as a member such as a casing It can be preferably used. Furthermore, in a preferred embodiment of the present invention, the occurrence of interference spots is suppressed and the visibility is good even outdoors.

  Hereinafter, the present invention will be described in detail.

(Base film)
In the present invention, the base film is not particularly limited, but has a moldability. Here, moldability means that a molded body can be formed by a molding process such as mold molding, pressure molding, or vacuum molding. Specifically, it has a film stress characteristic that can form a molded body without breaking the base film even when a high stress is partially generated in a portion that is locally elongated by molding.

  Examples of such a base film include plastics such as polyester, acrylic, cellulose, polyethylene, polypropylene, polyolefin, polyvinyl chloride, polycarbonate, phenol, and urethane. Examples include a film or sheet and a laminate of any two or more of these. A polyester film having a good balance between heat resistance and flexibility is preferable. Moreover, as a base film, the polyester film containing the copolyester excellent in the moldability at the time of the heat molding under low temperature and low pressure is also preferable.

  The base film of the present invention has a multilayer structure of three or more layers. When the layer having the ultraviolet absorber is the A layer and the other surfaces are the B layer and the C layer, the layer structure in the film thickness direction is B / A / B, B / A / C, B / A / C / B. Alternatively, a configuration such as B / A / C / A / B is conceivable. Each of the A to C layers may have the same or different configuration of the polyester resin, but preferably has a B / A / B configuration (two types and three layers). In any case, it is necessary to provide a layer containing an ultraviolet absorber as the intermediate layer. By containing an ultraviolet absorber in the intermediate layer, bleeding out of the additive can be suitably prevented, and deterioration of adhesion due to bleeding out of the additive can be suppressed.

  The ultraviolet absorber used in the present invention is a known substance. Examples of the ultraviolet absorber include an organic ultraviolet absorber and an inorganic ultraviolet absorber, and an organic ultraviolet absorber is preferable from the viewpoint of transparency. Examples of the organic ultraviolet absorber include benzotoazole, benzophenone, cyclic imino ester, and combinations thereof, but are not particularly limited as long as the absorbance is within the range defined by the present invention. However, from the viewpoint of durability, benzotoazole and cyclic imino ester are particularly preferable. When two or more kinds of ultraviolet absorbers are used in combination, ultraviolet rays having different wavelengths can be absorbed simultaneously, so that the ultraviolet absorption effect can be further improved.

Examples of the benzophenone ultraviolet absorber, benzotriazole ultraviolet absorber, and acrylonitrile ultraviolet absorber include 2- [2′-hydroxy-5 ′-(methacryloyloxymethyl) phenyl] -2H-benzotriazole, 2- [2 ′. -Hydroxy-5 '-(methacryloyloxyethyl) phenyl] -2H-benzotriazole, 2- [2'-hydroxy-5'-(methacryloyloxypropyl) phenyl] -2H-benzotriazole, 2,2'-dihydroxy- 4,4′-dimethoxybenzophenone, 2,2 ′, 4,4′-tetrahydroxybenzophenone, 2,4-di-tert-butyl-6- (5-chlorobenzotriazol-2-yl) phenol, 2- ( 2'-hydroxy-3'-tert-butyl-5'-methylphenyl)- 5-chlorobenzotriazole, 2- (5-chloro (2H) -benzotriazol-2-yl) -4-methyl-6- (tert-butyl) phenol, 2,2'-methylenebis (4- (1,1 , 3,3-tetramethylbutyl) -6- (2H-benzotriazol-2-yl) phenol, etc. Examples of cyclic imino ester UV absorbers include 2,2 ′-(1,4-phenylene). Bis (4H-3,1-benzoxazinon-4-one), 2-methyl-3,1-benzoxazin-4-one, 2-butyl-3,1-benzoxazin-4-one, 2-phenyl -3,1-benzoxazin-4-one, etc. However, it is not particularly limited thereto.

  In addition to the ultraviolet absorber, the resin constituting the base film can contain various additives in addition to the catalyst as long as the effects of the present invention are not hindered. Examples of additives include inorganic particles, heat resistant polymer particles, alkali metal compounds, alkaline earth metal compounds, phosphorus compounds, antistatic agents, light proofing agents, flame retardants, thermal stabilizers, antioxidants, and antigelling agents. And surfactants.

  The base film used in the present invention can contain particles in the surface layer in order to impart easy slipperiness. When a high degree of transparency is required for the film of the present invention, it is desirable that the base film does not substantially contain particles that cause a decrease in transparency.

  The above-mentioned “substantially contain no particles” means, for example, in the case of inorganic particles, a content of 50 ppm or less, preferably 10 ppm or less, most preferably less than the detection limit when inorganic elements are quantified by fluorescent X-ray analysis. Means quantity. This means that even if particles are not actively added to the base film, contaminants derived from foreign substances and raw material resin or dirt adhering to the line or equipment in the film manufacturing process will be peeled off and mixed into the film. It is because there is a case to do.

  As a method of blending the ultraviolet absorber into the base film, a known method can be used in combination.For example, a master batch is prepared by blending the dried ultraviolet absorber and the resin raw material in advance using a kneading extruder. It can be prepared and blended by a method of mixing a predetermined master batch and a resin raw material at the time of forming a base film.

  At this time, the concentration of the UV absorber in the master batch is preferably 5 to 30% by weight in order to uniformly disperse the UV absorber and economically blend it. When using polyester as a raw material resin, it is preferable to use a kneading extruder as a condition for producing a master batch, and to extrude at a temperature not lower than the melting point of the polyester raw material and not higher than 290 ° C. for 1 to 15 minutes. Above 290 ° C, the weight loss of the UV absorber is large, and the viscosity of the master batch is greatly reduced. When the extrusion temperature is 1 minute or less, uniform mixing of the UV absorber becomes difficult. At this time, if necessary, a stabilizer, a color tone adjusting agent, and an antistatic agent may be added.

  In the case of using a PET resin, the base film having a three-layer structure containing an ultraviolet absorber in the intermediate layer can be specifically produced as follows. PET pellets alone for the outer layer, and master batches containing UV absorbers for the intermediate layer and PET pellets are mixed at a predetermined ratio, dried and then fed to a known melt laminating extruder, Extruded into a sheet form from a die and cooled and solidified on a casting roll to make an unstretched film. That is, using two or more extruders, a three-layer manifold or a merging block (for example, a merging block having a square merging portion), a film layer constituting both outer layers and a film layer constituting an intermediate layer are laminated, An unstretched film is formed by extruding a three-layer sheet from the die and cooling with a casting roll. In the present invention, it is preferable to perform high-precision filtration during melt extrusion in order to remove foreign substances contained in the raw material polyester that cause optical defects. The filter particle size (initial filtration efficiency 95%) of the filter medium used for high-precision filtration of the molten resin is preferably 15 μm or less. When the filter particle size of the filter medium exceeds 15 μm, removal of foreign matters of 20 μm or more tends to be insufficient.

  The unstretched film obtained above is stretched 2.5 to 5.0 times in the longitudinal direction with a roll heated to 80 to 120 ° C. to obtain a uniaxially oriented polyester film. A coating solution is applied to one side or both sides of a uniaxially oriented polyester film as described below. Next, both ends of the film are gripped with clips, guided to a hot air zone heated to 80 to 180 ° C., and stretched 2.5 to 5.0 times in the width direction after drying. Subsequently, it is guided to a heat treatment zone of 220 to 240 ° C., and heat treatment is performed to complete crystal orientation. In this heat treatment step, a relaxation treatment of 1 to 12% may be performed in the width direction or the longitudinal direction as necessary.

  In addition, the base film is a surface activity such as corona discharge treatment, glow discharge treatment, flame treatment, ultraviolet irradiation treatment, electron beam irradiation treatment, ozone treatment, etc. within the range not impairing the object of the present invention. The treatment may be performed.

  The film of the present invention preferably has a transmittance at a wavelength of 380 nm of 20% or less. In particular, when used as a surface material of an outdoor mobile device, the transmittance at 380 nm is preferably 15% or less, and more preferably 5% or less. If the said transmittance | permeability is 20% or less, the quality change by the ultraviolet-ray of a base film can be suppressed. In order to reduce the transmittance at a wavelength of 380 nm to 20% or less, the concentration of the ultraviolet absorber and the thickness of the base film are appropriately adjusted. In addition, the transmittance | permeability in this invention is measured by the perpendicular | vertical method with respect to the plane of an adhesive property modified base film optical laminated film, and is measured using a spectrophotometer (for example, Hitachi U-3500 type). be able to.

  The thickness of the substrate film used in the present invention varies depending on the material, but when a polyester film is used, the lower limit is preferably 35 μm or more, more preferably 50 μm or more. On the other hand, the upper limit of the thickness is preferably 260 μm or less, more preferably 200 μm or less. When the thickness is small, not only the handling property becomes poor, but also when heated at the time of drying so as to reduce the residual solvent of the hard coat layer, the film tends to be wrinkled and flatness tends to be poor. On the other hand, when the thickness is large, not only is there a problem in terms of cost, but flatness due to curling tends to occur when the material is wound and stored in a roll shape.

(Middle layer)
The molding hard coat film of the present invention has a configuration in which a hard coat layer is laminated on one surface of a base film, and an intermediate layer may be provided for the purpose of improving the adhesion between the base film and the hard coat layer. preferable. In addition, when not containing particle | grains in a film in order to raise the transparency of a base film, the handleability 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 adhesion to the base film and the hard coat layer. If the resin constituting the base film and the hard coat layer is acrylic, specifically, among acrylic, copolymer polyester, and polyester urethane It is preferable to select at least one kind.

  When using the film of the present invention for the outer layer, in order to improve the visibility due to the occurrence of interference fringes, the refractive index difference between the polyester film of the substrate and the intermediate layer, the refractive index difference between the intermediate layer and the hard coat layer, respectively. It is preferable to control the refractive index of the intermediate layer by the type and content of the resin and additive constituting the intermediate layer so as to decrease. As such an intermediate layer, at least one of an aqueous polyester resin (A) and a water-soluble titanium chelate compound, a water-soluble titanium acylate compound, a water-soluble zirconium chelate compound, or a water-soluble zirconium acylate compound is used. An intermediate layer having (B) as a main constituent component is preferably used.

  The refractive index of the intermediate layer is higher than that of the polyester resin (A) alone by increasing the composition ratio of at least one of the titanium chelate compound, titanium acylate compound, zirconium chelate compound, or zirconium acylate compound (B). Can also be high.

  In the polyester resin (A) used in the present invention, an active site such as a hydroxyl group or a carboxyl group may be introduced into the molecular chain. A cross-linking reaction takes place in this place, resulting in a dense film.

  Since the polyester resin (A), which is a constituent component of the intermediate layer, is involved in adhesion to the base polyester film, the composition ratio (A / B) of the aqueous polyester resin (A) and the compound (B) is 10 / If it is less than 90, the adhesion to the substrate film is lowered, and the stretchability as an intermediate layer is lowered, and it may not be uniform during stretching. On the other hand, when the composition ratio (A / B) between the aqueous polyester resin (A) and the compound (B) exceeds 95/5, a water-soluble titanium acylate compound, a water-soluble zirconium chelate compound, or a water-soluble In some cases, crosslinking by the zirconium acylate compound (B) becomes poor and the refractive index also decreases. For this reason, the adhesion (humidity and heat resistance) under high temperature and high humidity is lowered, and the effect of suppressing iris-like colors under a fluorescent lamp is insufficient.

  The aqueous polyester resin (A) of the present invention is dissolved or dispersed in water or a water-soluble organic solvent (for example, an aqueous solution containing less than 50% by mass of alcohol, alkyl cellosolve, ketone, or ether). Means a polyester resin capable of In order to impart water resistance to the polyester resin, it is important to introduce a hydrophilic group such as a hydroxyl group, a carboxyl group, a sulfonic acid group, a phosphoric acid group, or an ether group into the molecular chain of the polyester resin. Among the hydrophilic groups, sulfonic acid groups are preferable from the viewpoint of coating film properties and adhesion.

  When the sulfonic acid group is introduced into the polyester, the sulfonic acid compound is more preferably 1 to 10 mol% in the total acid component of the polyester. When the amount of the sulfonic acid group is less than 1 mol%, the polyester resin does not exhibit water, and a water-soluble titanium chelate compound, a water-soluble titanium acylate compound, a water-soluble zirconium chelate compound, or a water-soluble zirconium acylate compound Since the compatibility with at least one of (B) also decreases, it becomes difficult to obtain a uniform and transparent intermediate layer. Moreover, when the amount of sulfonic acid group exceeds 10 mol%, it becomes easy to be inferior to the adhesiveness (humidity heat resistance) under high temperature and high humidity.

  Further, the aqueous polyester resin (A) preferably has a glass transition temperature of 40 ° C. or higher. For this reason, the acid component of the polyester resin (A) is preferably composed mainly of an aromatic group such as terephthalic acid, isophthalic acid, or naphthalenedicarboxylic acid. The glycol component is preferably a glycol having a relatively small carbon number such as ethylene glycol, propane glycol, 1,4-butanediol, or neopentyl glycol, or an aromatic system such as an ethylene oxide adduct of bisphenol A. Further, as a raw material of the polyester resin (A), a rigid component such as biphenyl or a dicarboxylic acid component or diol component having a high refractive index atom such as bromine or sulfur may be used within a range in which the physical properties of the film do not deteriorate. Good. When the glass transition temperature of the polyester resin (A) is less than 40 ° C., the adhesiveness (humidity heat resistance) under high temperature and high humidity tends to be insufficient. Furthermore, since the refractive index of the polyester resin (A) also decreases, the refractive index of the intermediate layer also decreases. As a result, the suppression of iris color under fluorescent lamps tends to be insufficient.

  The other main component of the intermediate layer is at least one (B) of a water-soluble titanium chelate compound, a water-soluble titanium acylate compound, a water-soluble zirconium chelate compound, or a water-soluble zirconium acylate compound. The above water-soluble means to dissolve in water or an aqueous solution containing less than 50% by mass of a water-soluble organic solvent.

  Examples of water-soluble titanium chelate compounds include diisopropoxybis (acetylacetonato) titanium, isopropoxy (2-ethyl-1,3-hexanediolato) titanium, diisopropoxybis (triethanolaminato) titanium, di -N-butoxybis (triethanolaminato) titanium, hydroxybis (lactato) titanium, ammonium salt of hydroxybis (lactato) titanium, titanium beloxocitrate ammonium salt and the like.

  Examples of the water-soluble titanium acylate compound include oxotitanium bis (monoammonium oxalate), and examples of the water-soluble zirconium compound include zirconium tetraacetylacetonate and zirconium acetate.

  In the intermediate layer, a resin other than the main component, for example, an acrylic resin, a polyurethane resin, a polyester resin, an alkyd resin, a vinyl resin such as polyvinyl alcohol, or the like is used in a range that does not affect the effects of the present invention. It doesn't matter. Further, the combined use of the crosslinking agent is not particularly limited as long as the effect of the present invention is not affected. Examples of crosslinking agents that can be used include adducts of urea, melamine, benzoguanamine, and the like with formaldehyde, amino resins such as alkyl ether compounds composed of these adducts and alcohols having 1 to 6 carbon atoms, polyfunctional epoxy compounds, Examples thereof include a polyfunctional isocyanate compound, a blocked isocyanate compound, a polyfunctional aziridine compound, and an oxazoline compound.

  As a method for providing the intermediate layer, a coating method is preferable. As the coating method, using a known coating method such as gravure coating method, kiss coating method, dip method, spray coating method, curtain coating method, air knife coating method, blade coating method, reverse roll coating method, etc. It can be provided by an in-line coating method in which a coating layer is provided, or an offline coating method in which a coating layer is provided after film production. Of these methods, the in-line coating method is not only excellent in terms of cost, but by adding particles to the intermediate layer, it is not necessary to include particles in the base film, so that the transparency can be highly improved. This is preferable because it is possible.

(Hard coat layer)
In the hard coat film for molding of the present invention, a hard coat layer is laminated directly or via an intermediate layer on at least one surface of the base film. In the present invention, the hard coat layer has a coating with a hardness higher than that of the base material in order to supplement the surface hardness of the base material made of the base film and improve the scratch resistance, and also to deformation during molding. The layer which has the outstanding moldability which can be followed is shown.

  In the present invention, the ionizing radiation curable compound contained in the coating solution contains one or more ionizing radiation curable compounds having three or more functional groups in addition to the one or bifunctional ionizing radiation curable compound. is important. In the hard coat layer after curing, a tri- or higher functional ionizing radiation curable compound component having a high crosslinking density is used as a hard segment, and the mono- and / or bi-functional ionizing radiation curable compound reacts to form a hard segment, and 1 and A bifunctional ionizing radiation curable compound component is present as a soft segment. Thus, by adjusting two or more types of ionizing radiation curable compounds having different functional numbers within a specific concentration range, a hetero-crosslinked structure is introduced into the hard coat layer, and the surface hardness and scratch resistance are improved by the hard segment. It was possible to obtain a remarkable effect of providing both the contradictory properties of imparting and imparting moldability by the stretchability of the soft segment.

  In the present invention, in order to achieve both high surface hardness and excellent moldability, specifically, pencil hardness of H or higher and elongation of 10% or higher, 1 in the ionizing radiation curable compound contained in the coating solution. It is important that the content of the bifunctional ionizing radiation curable compound is 5% by mass or more and 95% by mass or less. When the content is less than 5% by mass, not only the flexibility of the coating is lowered, but also cracks are generated in the hard coat layer during molding, which is not preferable. Moreover, when the said content exceeds 95 mass%, it is difficult to obtain the cured film which has sufficient surface hardness and abrasion resistance. The lower limit of the content is more preferably 10% by mass or more, and further preferably 20% by mass or more. 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 more preferable. . When the content of the monofunctional 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 the surface height and the moldability are more highly balanced. Specifically, pencil hardness of 2H or more and elongation of 20% or more can be achieved at the same time, and high hardness and high workability are required at the same time, for example, for nameplates such as automobiles and casings for portable devices. It is suitable for a molding film.

  Furthermore, the present inventor has found that, in addition to the above-described embodiment, by using an ionizing radiation curable compound having an amino group as the ionizing radiation curable compound, both surface hardness and moldability can be achieved to a higher degree. That is, it is preferable that at least one ionizing radiation curable compound contained in the coating solution has an amino group. About the said effect | action by using the compound which has an amino group as an ionizing radiation hardening compound, it thinks as follows. When the hard coat layer has a partial hardness distribution difference, local cracking is likely to occur when the hard coat layer is stretched. As a factor of such a difference in the partial hardness distribution, there is polymerization inhibition (oxygen inhibition) of the ionizing radiation curable resin by oxygen. Here, when a compound having an amino group is used as the ionizing radiation curing compound, the amino group traps radical oxygen, and the influence of oxygen inhibition on the curing reaction of the surface layer portion of the hard coat layer is reduced. A uniform curing reaction proceeds. As a result, the stress applied to the hard coat layer during molding is dispersed throughout the layer, and the occurrence of cracks during molding is suppressed. Therefore, it is considered that the surface height and moldability can be achieved at a higher level. In addition to the above effects, the surface of the hard coat layer is hardened more than when no amino group is contained due to the effect of fast curing of the coating film due to the inclusion of amino groups as the ionizing radiation curable resin. Hardness can be improved.

  The content of the ionizing radiation curable compound containing an amino group in the ionizing radiation curable compound contained in the coating solution is preferably 2.5% by mass or more and 95% by mass or less. The lower limit of the content of the ionizing radiation curable compound containing an amino group in the ionizing radiation curable compound contained in the coating solution is more preferably 5% by mass or more, and further preferably 10% by mass or more. . The upper limit of the content is more preferably 92.5% by mass or less, further preferably 90% by mass or less, and further preferably 50% by 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 solution is less than 2.5% by mass, it is difficult to uniformly cure the entire hard coat layer. It becomes difficult to obtain resistance to cracks. Further, when the ionizing radiation curable compound containing an amino group becomes high in concentration, yellowing of the hard coat layer becomes strong due to the amino group. Therefore, when the content exceeds 95% by mass, high transparency is impaired. May be. For example, when printing is performed on the surface on which the hard coat layer is not laminated, the color b value of the film is preferably 2 or less. In this case, the ionizing radiation curable compound containing the amino group is 92.5% by mass or less. It is preferable that

  In the present invention, the coating solution contains a monofunctional and / or bifunctional ionizing radiation curable compound and an ionizing radiation curable compound having three or more functional groups. The ionizing radiation curable compound of the part may be any one containing an amino group. Further, any one of a monofunctional ionizing radiation curable compound, a bifunctional ionizing radiation curable compound, or an ionizing radiation curable compound having three or more functional groups is an ionizing radiation curable compound containing an amino group. Is also a preferred embodiment.

  When an acrylate ionizing radiation curable compound is used as the ionizing radiation curable compound having an amino group, examples of the acrylate ionizing radiation curable compound having an amino group include acrylamide, 7-amino-3,7-dimethyloctyl ( (Meth) acrylate, isobutoxymethyl (meth) acrylamide, t-octyl (meth) acrylamide, diacetone (meth) acrylamide, dimethylaminoethyl (meth) acrylate, diethylaminoethyl (meth) acrylate, N, N-dimethyl (meth) acrylamide Examples include tetrachlorophenyl (meth) acrylate and N-vinylformamide.

  In addition to the above embodiment, the inventor of the present application has found that by including particles in the hard coat layer, the moldability can be further improved, and the surface hardness and the moldability can be enhanced at a high level. About the effect | action which a moldability improves more by containing particle | grains in a hard-coat layer, it thinks as follows. When the hardness of the hard coat layer is increased, a strong stress is temporarily generated in the hard coat layer having high hardness at the time of molding, so that the hard coat layer is cracked at once. Here, the presence of particles in the hard coat layer relieves 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 and suppresses the generation of cracks. It is thought that there is an effect that micro cracks that cannot be confirmed by visual inspection to the extent that it does not impair the appearance are generated in advance, the occurrence of fatal cracks in the hard coat layer is delayed, and as a result, the effect of improving moldability appears It is done.

  Examples of the particles included in the hard coat layer include amorphous silica, crystalline silica, silica-alumina composite oxide, kaolinite, talc, calcium carbonate (calcite type, vaterite type), zeolite, alumina, hydroxyapatite, and the like. Heat-resistant polymer particles such as 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 particles, Organic / inorganic hybrid fine particles such as silica / acrylic composite compounds may be mentioned, but in the present invention, the type of particles is not particularly limited.

  Examples of the shape of the particles include a spherical shape, a block shape, a plate shape, a fiber shape, and a flake shape. However, the shape of the particles is not particularly limited. In view of the above, spherical particles are preferable.

  In the present invention, the average particle diameter of the particles is preferably 10 nm or more and 300 nm or less, the lower limit is preferably 40 nm or more, and the upper limit is preferably 200 nm or less, particularly the lower limit is 50 nm or more and the upper limit is 100 nm or less. preferable. When the average particle diameter of the particles is smaller than 10 nm, the average particle diameter is too small, and therefore, any or all of the effects of improving the surface hardness, scratch resistance, and moldability described above may be small. Moreover, when it exceeds 300 nm, a hard-coat layer becomes weak and a moldability may fall. The average particle diameter is an average particle diameter measured by dispersing the particles in a solvent that does not swell using a Coulter counter (manufactured by Beckman Coulter, Multisizer II type).

  In the present invention, the content of the particles to be contained in the hard coat layer is preferably 5% by mass or more and 70% by mass or less as a solid component in the hard coat layer, and particularly preferably, the lower limit of the content is 15% by mass. The upper limit is 50% by mass or less. When the content of the particles is less than 5% by mass, any of the above-described effects of improving the surface hardness, scratch resistance, and moldability due to the addition of the particles may be reduced. On the other hand, when the content of the particles exceeds 70% by mass, a large amount of the fine cracks described above are generated at the time of molding, and haze increases (whitens), thereby impairing the transparency of the molded body.

  Furthermore, in addition to the above embodiment, the inventor of the present application contains an ionizing radiation curable silicone resin in the hard coat layer, thereby imparting slipperiness, improving the scratch resistance of the surface, and further increasing the surface hardness and moldability. I found that they can be compatible. Further, according to such an embodiment, the ionizing radiation curable silicone resin itself is cross-linked by the curing reaction, and in some cases, the ionizing radiation curable resin constituting the hard coat layer is also cross-linked. When using a molded body formed by molding the hard coat film for molding of the present invention for a long period of time, it is possible to obtain a new effect that the function of the surface scratch resistance over time is not impaired. it can.

  The ionizing radiation curable silicone resin is, for example, a radical addition type having an alkenyl group and a mercapto group, a hydrosilylation reaction type having an alkenyl group and a hydrogen atom, a cationic polymerization type having an epoxy group, and a (meth) acryl group. A radical polymerization type silicone resin having Among these, a cationic polymerization type having an epoxy group and a radical polymerization type having a (meth) acryl group are preferable.

  Examples of silicone resins having an epoxy group or (meth) acryl group in the molecule include epoxypropoxypropyl-terminated polydimethylsiloxane, (epoxycyclohexylethyl) methylsiloxane-dimethylsiloxane copolymer, methacryloxypropyl-terminated polydimethylsiloxane, and acryloxy. And propyl-terminated polydimethylsiloxane. Examples of the silicone resin having a vinyl group in the molecule include terminal vinyl polydimethylsiloxane and vinylmethylsiloxane homopolymer.

  In the present invention, the addition amount of the ionizing radiation curable silicone resin to be contained in the hard coat layer is preferably 0.15 to 15 parts by mass with respect to 100 parts by mass of the ionizing radiation curable compound for constituting the hard coat layer. More preferably, 0.3 to 13 parts by mass, and still more preferably 0.5 to 5 parts by mass are blended. When the blending amount of the ionizing radiation curable silicone resin is less than the lower limit, the effect of improving the scratch resistance when formed into a molded product is poor, and when it exceeds the upper limit, the hard coat layer is sufficiently cured when formed. It may not be possible. The ionizing radiation curable silicone resin contained in the hard coat layer may be used alone or in combination of two or more.

  In the present invention, it is desirable to appropriately select or combine the use of a compound having an amino group as the ionizing radiation curable compound and the addition of particles to the hard coat layer according to the use of the film for molding as described above. . A particularly preferred embodiment is a combination thereof. As a result, the surface hardness and moldability of the hard coat layer can be made extremely highly compatible. Specifically, the surface hardness is 2H or higher and the elongation is 20% or higher, more preferably the surface hardness is 2H or higher. In addition, a molding hard coat film having an elongation of 30% or more can be obtained, and for example, it can be suitably used for applications such as a cover member for automobiles, a deep housing or container.

  In the present invention, as a method of polymerizing and / or reacting the coating solution, a method of irradiating with an electron beam, radiation, or ultraviolet rays may be mentioned. When ultraviolet rays are irradiated, a photopolymerization initiator is added to the coating solution. Is desirable.

  Specific examples of the photopolymerization initiator include acetophenone, 2,2-diethoxyacetophenone, p-dimethylacetophenone, p-dimethylaminopropiophenone, benzophenone, 2-chlorobenzophenone, 4,4′-dichlorobenzophenone, 4,4′-bisdiethylaminobenzophenone, Michler's ketone, benzyl, benzoin, benzoin methyl ether, benzoin ethyl ether, benzoin isopropyl ether, methyl benzoyl formate, p-isopropyl-α-hydroxyisobutylphenone, α-hydroxyisobutylphenone, 2, Carbonyl compounds such as 2-dimethoxy-2-phenylacetophenone and 1-hydroxycyclohexyl phenyl ketone, tetramethylthiuram monosulfide, tetramethylthiuramdis Examples thereof include sulfur compounds such as rufide, thioxanthone, 2-chlorothioxanthone, and 2-methylthioxanthone, and peroxide compounds such as benzoyl peroxide and di-t-butyl peroxide. Examples of these photopolymerization-initiated peroxide compounds such as t-butyl peroxide. These photopolymerization initiators may be used alone or in combination of two or more. The addition amount of the photopolymerization initiator is suitably 0.01 parts by weight or more and 15 parts by weight or less per 100 parts by weight of the ionizing radiation curable compound contained in the coating solution, and the reaction is slow when the amount used is small. In addition to the poor quality, the remaining unreacted material does not provide sufficient surface hardness and scratch resistance. On the other hand, when the addition amount is large, there is a problem that the hard coat layer is yellowed by the photopolymerization initiator.

  In the present invention, the coating solution contains a known thermal polymerization inhibitor such as hydroquinone, hydroquinone monomethyl ether, 2,5-t-butyl hydroquinone, etc. in order to prevent thermal polymerization during production and dark reaction during storage. It is preferable to add. The addition amount of the thermal polymerization inhibitor is preferably 0.005 parts by mass or more and 0.05 parts by mass or less per 100 parts by mass of the ionizing radiation curable compound contained in the coating solution.

  In the present invention, an organic solvent can be blended in the coating solution for the purpose of improving workability during coating and controlling the coating film thickness as long as the object of the present invention is not impaired.

  As the organic solvent, when a base film having a low melting point is used, it may be necessary to adjust the drying temperature after coating to 150 ° C. or lower, so the boiling point of the organic solvent is 50 ° C. or higher and 150 ° C. or lower. Is preferred. Specific examples include alcohol solvents such as methanol, ethanol and isopropyl alcohol, acetate solvents such as methyl acetate, ethyl acetate and butyl acetate, ketone solvents such as acetone and methyl ethyl ketone, and aromatic solvents such as toluene. And cyclic ether solvents such as dioxane. These solvents can be used alone or in admixture of two or more.

  In the present invention, the coating liquid should have a surface tension lowered to improve the coating appearance of the hard coat layer, in particular, dents due to fine bubbles, dents due to adhesion of foreign matters, and repellency in the drying process. For the purpose, a surfactant can be contained.

  As the surfactant, known cationic, anionic, and nonionic surfactants can be suitably used, but they have polar groups due to problems such as alteration of the coating solution and poor adhesion of the hard coat layer to the base film. The nonionic type | system | group which is not carried out is preferable, and also the silicone type surfactant or fluorine-type surfactant which is excellent in surface active ability is preferable.

  Silicone surfactants include dimethyl silicon, amino silane, acrylic silane, vinyl benzyl silane, vinyl benzyl silyl amino silane, glycid silane, mercapto silane, dimethyl silane, polydimethyl siloxane, polyalkoxy siloxane, hydrodiene modified siloxane, vinyl modified siloxane, Vitroxy modified siloxane, amino modified siloxane, carboxyl modified siloxane, halogenated modified siloxane, epoxy modified siloxane, methacryloxy modified siloxane, mercapto modified siloxane, fluorine modified siloxane, alkyl group modified siloxane, phenyl modified siloxane, alkylene oxide modified siloxane, etc. .

  Fluorosurfactants include ethylene tetrafluoride, perfluoroalkyl ammonium salt, perfluoroalkyl sulfonic acid amide, sodium perfluoroalkyl sulfonate, perfluoroalkyl potassium salt, perfluoroalkyl carboxylate, perfluoroalkyl sulfone. Acid salts, perfluoroalkyl ethylene oxide adducts, perfluoroalkyl trimethyl ammonium salts, perfluoroalkyl amino sulfonates, perfluoroalkyl phosphate esters, perfluoroalkyl alkyl compounds, perfluoroalkyl alkyl betaines, perfluoroalkyl halides, etc. Is mentioned.

  From the viewpoint of improvement in coating appearance and slipperiness, the content of the surfactant is preferably 0.01% by mass or more with respect to the coating liquid constituting the hard coat layer. On the other hand, since the surfactant bleeds out to the surface of the hard coat layer and contaminates what touched the hard coat layer, the surfactant content is preferably 2.00% by mass or less.

  The surfactant used preferably has an HLB of 2 or more and 12 or less. By using a surfactant having an HLB of 2 or more, the leveling property due to the surface activity can be improved. The HLB of the surfactant is more preferably 3 or more, and particularly preferably 4 or more. On the other hand, by using a surfactant having an HLB of 12 or less, deterioration of slipperiness can be suppressed.

  Note that HLB means W.A. of Atlas Powder, Inc. of the United States. C. Griffin named Hydrophile Lyophile Balance and is a value obtained by indexing the balance between the hydrophilic group and the lipophilic group contained in the surfactant molecule as a characteristic value. It means that the lower the HLB value, the more lipophilic, while the higher the HLB value, the higher the hydrophilicity.

  Various additives can be blended in the hard coat layer of the present invention as required. Examples thereof include fluorine and silicon compounds for imparting water repellency, antifoaming agents for improving coatability and appearance, and antistatic agents and coloring dyes and pigments.

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

  As a method for laminating the hard coat layer, a known method may be mentioned, and a method in which the coating liquid is applied and dried on a base film and then cured is preferable. As a coating method, there are known coating methods such as a gravure coating method, a kiss coating method, a dip method, a spray coating method, a curtain coating method, an air knife coating method, a blade coating method, a reverse roll coating method, a bar coating method, and a lip coating method. Can be mentioned. Among these, a gravure coating method, particularly a reverse gravure method, which can be applied by a roll-to-roll method and can be applied uniformly, is preferable.

  As a method of dissolving or dispersing the ionizing radiation curable compound, particles, photopolymerization initiator and the like contained in the coating solution in an organic solvent, a method of stirring and dispersing them under heating is preferable. By heating the coating solution, the solubility of the ionizing radiation curable compound, particles and photopolymerization initiator can be improved. Therefore, the deterioration of the coating appearance due to undissolved materials can be suppressed.

  A well-known thing can be used for a disperser. Specific examples include a ball mill, a sand mill, an attritor, a roll mill, an agitator, a colloid mill, an ultrasonic homogenizer, a homomixer, a pearl mill, a wet jet mill, a paint shaker, a butterfly mixer, a planetary mixer, and a Henschel mixer.

  The concentration of the solid content of the ionizing radiation curable compound, particles, photopolymerization initiator and the like contained in the coating solution is preferably 5% by mass or more and 70% by mass. By adjusting the concentration of the solid content of the coating liquid to 5% by mass or more, it is possible to suppress a decrease in productivity due to a long drying time after coating. On the other hand, by adjusting the concentration of the solid content of the coating solution to 70% by mass or less, it is possible to prevent deterioration in leveling properties due to an increase in the viscosity of the coating solution and accompanying deterioration in coating appearance. From the viewpoint of coating appearance, the solid content concentration of the coating liquid, the type of organic solvent, and the type of surfactant are adjusted so that the viscosity of the coating liquid is in the range of 0.5 cps to 300 cps. It is preferable.

  The thickness of the hard coat layer after coating and curing depends on the degree of elongation during molding, but it is preferable that the thickness of the hard coat layer after molding be 0.5 μm or more and 50 μm 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. Further, 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, further preferably 60 μm or less, and further preferably 20 μm or less. When the thickness of the hard coat layer is less than 0.6 μm, it is difficult to obtain hard coat properties. Conversely, when the thickness exceeds 100 μm, the hard coat layer tends to be poorly cured or curled due to cure shrinkage.

  When pre-drying is required, such as when an organic solvent is blended in the coating solution, known hot air drying, infrared heaters and the like can be used as a method of applying on the base film and drying, but hot air with a fast drying speed is used. Drying is preferred.

  The drying temperature after coating is preferably 40 ° C. or higher and 120 ° C. or lower, and particularly preferably the lower limit is 45 ° C. or higher and the upper limit is 80 ° C. or lower. If it is less than 40 degreeC, the organic solvent contained in a coating liquid cannot fully be removed, and problems, such as brushing, may generate | occur | produce. On the other hand, when the temperature exceeds 120 ° C., minute defects of the coating film such as minute coating removal from bubbles, minute repellency, and cracks are likely to occur, and the appearance may be poor. In addition, the film shrinks strongly due to heat, and the flatness of the film deteriorates due to heat wrinkles, so that uniform stretching cannot be obtained during molding, or local stretching occurs and the film breaks. Becomes defective.

  The tension of the film applied during drying is preferably 50 N / m or more and 300 N / m or less, particularly preferably the lower limit is 100 N / m or more and the upper limit is 250 N / m or less. When the tension of the film is less than 50 N / m, the traveling film meanders and it is impossible to apply the coating solution. On the other hand, when it exceeds 300 N / m, wrinkles are generated in the film, and the flatness is deteriorated and the appearance of the wound film is deteriorated. Furthermore, when the base film is a film having a low temperature and excellent moldability, the film is stretched in the traveling direction during drying and contracts in the width direction, and in the worst case, a problem arises in productivity such as breaking.

  In the present invention, a hard coat layer, an antistatic layer, an easy adhesion layer, an adhesive layer, an easy slip layer, an electromagnetic wave absorption layer, a dye, a pigment, etc., as long as the effect of the present invention is not impaired on the surface not provided with the hard coat layer. Other functions such as a resin layer containing a dye may be added.

In the present invention, the hard coat layer is formed by irradiating the coating solution with ultraviolet rays. As the integrated quantity of light to be irradiated, preferably 50 mJ / cm ² or more 1000 mJ / cm ² or less, and more preferably the lower limit is 300 mJ / cm ² or more, the upper limit is 700 mJ / cm ² or less. Note that it is desirable to perform irradiation in a nitrogen gas atmosphere because oxygen inhibition is reduced and scratch resistance is improved. When the integrated light quantity 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 reduced. When the integrated light quantity exceeds 1000 mJ / cm ² , the base film may be deformed due to the influence of heat. The integrated light amount in the present invention can be measured by “UVR-T35” manufactured by Topcon.

  Further, when the coating solution is cured with an electron beam, the irradiation dose is preferably 5 kGy or more and 100 kGy or less, and more preferably the upper limit is 30 kGy or more and the lower limit is 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 reduced. When it exceeds 100 kGy, the lifetime of the electron beam irradiation tube is remarkably reduced, which is not preferable in terms of production cost.

(Hard coat film roll for molding)
The molding hard coat film roll of the present invention is obtained through a step of continuously winding a long molding hard coat film in a roll shape around a cylindrical core. By using the hard coat film roll for molding, productivity at the time of processing can be improved, and further, it can contribute to the stability of the quality of the molded body. The length of the molding hard coat film roll obtained by continuously winding the long molding hard coat film into a roll on a cylindrical core is not particularly limited depending on the application, but is preferably 50 m or more and 5000 m or less, 100 m or more and 3000 m or less is more preferable. When the winding length is short, for example, the frequency of switching the hard coat film for molding at the time of processing the printed layer in the subsequent process is increased and workability is deteriorated. On the other hand, when the winding length is long, the molding hard coat film expands and contracts due to the external environmental temperature, and winding tightening occurs, resulting in a poor appearance of the core.

  The width of the hard coat film roll for molding varies depending on the application and is not particularly limited, but is preferably 100 mm or more and 2000 mm or less, more preferably 500 mm or more and 1500 mm or less from the viewpoint of workability.

  The cylindrical core around which the hard coat film for molding is wound is preferably a plastic core. When a commonly used paper core is used, paper dust or the like is generated and tends to adhere to the hard coat layer and become defective. As the plastic core, known ones can be preferably used, but a polypropylene core and an FRP core are preferable in terms of strength. The size of the cylindrical core is preferably 3 to 6 inches in diameter. When a core having a small diameter is used, the winding core is wrinkled and the handling property in the subsequent process becomes poor. On the other hand, when the diameter is large, the roll diameter becomes large and the handling property becomes poor.

  In order to wind the molding hard coat film around the core, it is preferable to start winding after fixing the molding hard coat film to the core via a double-sided tape. When a double-sided tape is not used, winding deviation is likely to occur during winding or during transportation. Although a well-known thing can be used as a double-sided tape, what has an adhesion layer on both surfaces of a plastic film is preferable at the point of generation | occurrence | production of paper dust, and an intensity | strength. The thickness of the double-sided tape is preferably 5 μm or more and 50 μm or less. When it is thin, the strength is lowered and workability is deteriorated, and the fixing force of the film is lowered. On the other hand, when it is thick, the flatness of the hard coat film for molding the core portion becomes poor due to a step due to the tape.

  In this invention, it is preferable to provide an unevenness | corrugation (emboss) to the both ends of the width direction of the hard-coat film for a shaping | molding. By imparting irregularities, it becomes difficult to leave marks due to the double-sided tape at the core, and the functionality described above laminated on the hard coat layer and the base film surface layer on the opposite side or on the base film is given. The part which contacts with the layer which fell is reduced, and the storage stability in a roll form becomes favorable. The lower limit of the height of the unevenness is preferably 10 μm, more preferably 15 μm. On the other hand, the upper limit of the height of the unevenness is preferably 40 μm, more preferably 35 μm. When the height of the unevenness is too low, the effect of improving the storage stability in the roll form due to the unevenness is reduced. On the other hand, if the height of the unevenness is too high, winding deviation or the like is likely to occur during transportation. A publicly known method can be used as a method of giving unevenness. Specifically, a method of pressing the metal roll having protrusions on the surface to give irregularities can be mentioned. In addition, it is preferable to give uneven | corrugated processing to a base film previously, before forming a hard-coat layer on a base film.

(Molded body)
The hard coating film for molding of the present invention is a molding material that 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, and stretch molding. It is suitable as. In the case of molding using the molding hard coat film of the present invention, the hard coat layer follows the deformation during molding and no cracks are generated, and the surface hardness and scratch resistance can be maintained.

  The thickness of the hard coat layer of the molded body formed by molding the above-described hard coat film for molding is preferably 0.5 μm or more and 50 μm or less, and particularly preferably 0.5 μm or more and 10 μm or less. When the thickness of the hard coat layer of the molded body is less than 0.5 μm, hard coat properties cannot be obtained, and when heat is applied to the molded body in terms of heat resistance, the hard film cannot follow the shrinkage of the base film. The surface of the coat layer becomes rough like a wave, and the appearance is impaired. On the other hand, when it exceeds 50 μm, there is no difference in the surface hardness at the thickness of the hard coat layer beyond that, and the merit is reduced in terms of quality.

  The molded body molded in this way has a hard coat layer to compensate for surface hardness, so it is mounted at a position where it touches the outside and is required to have scratch resistance. It can be suitably used as a molding member such as a building material, a decorative board, a decorative steel plate, and a transfer sheet.

  Hereinafter, the present invention will be described in detail by way of examples. The film properties obtained in each example were measured and evaluated by the following methods.

(1) Elongation The obtained hard coat film for molding was cut into a strip-shaped sample piece having a length of 10 mm and a width of 150 mm. In an environment where the actual temperature of the film sample piece is 160 ° C., while visually observing the appearance, the film is gripped at both ends and pulled at a test speed of 250 mm / min, and when the hard coat layer is cracked or whitened, The length was measured.
When the length of the film sample piece before the test was a and the length of the film sample piece after the test was b, the elongation was calculated by the following formula.
Elongation (%) = (b−a) × 100 / a
Here, it was judged that those having an elongation of 10% or more were excellent in moldability, and those having an elongation of 30% or more were particularly excellent in moldability.

(2) Pencil hardness The pencil hardness of the hard coat layer of the obtained molding hard coat film was measured according to JIS-K5600. The indentation (scratch) was judged visually.
Here, those having a pencil hardness of H or higher were judged to have excellent surface hardness, and those having a pencil hardness of 2H or higher were judged to have particularly excellent surface hardness.

(3) Scratch resistance The scratch resistance of the hard coat layer of the obtained molding hard coat film was measured according to JIS-K5600. The hard coat layer surface was reciprocated 20 times with # 0000 steel wool at a load of 500 gf, and the presence or absence of scratches and the extent of the scratches were visually observed. The rank was determined according to the following criteria based on the observation results. The scratch resistance rank was C or higher, and there was scratch resistance, and those of B or higher were judged to have good scratch resistance.
A: There is no generation of scratches or thin scratches are observed in a small amount.
B: Although a thin wound is observed, a deep wound is not observed.
C: Narrow scratches are observed, and a small amount of deep scratches are also observed.
D: A lot of deep scratches are observed.

(4) Light transmittance at a wavelength of 380 nm Using a spectrophotometer (manufactured by Hitachi, U-3500 type), the light transmittance in a wavelength region of 300 to 500 nm is measured using an air layer as a standard, and the transmittance at a wavelength of 380 nm is obtained. Asked.

(5) Pencil hardness after molding, thickness of hard coat layer In the elongation evaluation of (1) above, by stopping pulling immediately before the occurrence of cracks, a molded body after stretch molding was obtained. The pencil hardness after molding was evaluated by the evaluation method (2). Further, the spectral reflectance at the center of the film sample piece (molded body) after molding is obtained from a spectrophotometer (manufactured by Shimadzu Corporation, UV-3150 type), and the peak valley method is calculated from the waveform at a wavelength of 400 nm to 600 nm. Using this, the thickness of the hard coat layer was calculated. The refractive index of the hard coat layer required at that time is to prepare a single film of the hard coat layer from the hard coat coating solution of each example and comparative example, and use an Abbe refractometer (NAR-1T SOLID, manufactured by Atago). Asked.

(6) Interference fringe improvement (iris color)
The obtained hard coat film for molding was cut into an area of 10 cm (film width direction) × 15 cm (film longitudinal direction) to prepare a sample film. A black glossy tape (manufactured by Nitto Denko Corporation, vinyl tape No. 21; black) was bonded to the surface opposite to the hard coat layer surface of the obtained sample film. The sample film was observed with the hard coat surface as the upper surface and a three-wavelength daylight white color (National Palook, FL 15EX-N 15W) as a light source. The results of visual observation were ranked according to the following criteria.
○: Iridescent color is not seen △: Slightly irisy color is seen ×: Clear iris-like color is observed
