Description
Technical Field
The present invention relates to an adhesive composition containing an antistatic agent, and an adhesive film and a surface protective film using the same. More particularly, the present invention relates to an adhesive composition which has excellent adhesive properties such as adhesive force in a balanced manner at a low peeling speed and a high peeling speed and which can achieve both antistatic properties and antifouling properties, and an adhesive film and a surface protective film using the adhesive composition.
Background
Conventionally, in a process for manufacturing an optical member such as a polarizing plate as a member constituting a liquid crystal display, a surface protective film is bonded to temporarily protect the surface of the optical member. Such a surface protective film is used only in a process of manufacturing an optical member, and is peeled and removed from the optical member when the optical member is mounted on a liquid crystal display. Such a surface protective film for protecting the surface of an optical member is generally also called a process film since it is used only in the process of manufacturing the optical member.
In the surface protective film used in the process of producing the optical member, an adhesive layer is formed on one surface of a polyethylene terephthalate (PET) resin film having optical transparency. Before being bonded to an optical member, a release film subjected to release treatment is bonded to the surface of an adhesive agent layer in order to protect the adhesive agent layer of the surface protective film.
Optical members such as polarizing plates are subjected to product inspection involving optical evaluations such as display capability, color tone, contrast, and impurity contamination of the liquid crystal display panel in a state where a surface protective film is bonded thereto. Therefore, as a performance requirement for the surface protective film, it is required that the adhesive layer does not adhere to bubbles or impurities and low molecular weight components of the adhesive composition, that is, has a stain resistance.
In addition, when the surface protective film is peeled from an optical member such as a polarizing plate, peeling static electricity generated along with static electricity generated when the adhesive layer and an adherend are peeled may affect a failure of an electric control circuit of a liquid crystal display. Therefore, the adhesive layer of the surface protective film is required to have excellent antistatic performance.
Further, in recent years, as a protective layer (also referred to as a protective film) of a polarizer of a polarizing plate, in addition to conventionally used Triacetylcellulose (TAC), use of a material which is likely to generate peeling static electricity when peeling a surface protective film of a polarizing plate, such as acrylic resin such as polymethyl methacrylate (PMMA), polyester resin such as polyethylene terephthalate (PET), cyclic olefin polymer, polycarbonate, or the like, has been expanded. Therefore, the antistatic performance required of the adhesive layer for the surface protective film of the polarizing plate is required to be more excellent than ever.
In addition, when the surface protective film is finally peeled from an optical member such as a polarizing plate, it is required to be quickly peeled. That is, the variation of the adhesive force due to the peeling speed is required to be small so that peeling can be performed quickly even in the case of high-speed peeling.
As described above, in recent years, from the viewpoint of ease of use in using a surface protective film, the adhesive layer constituting the surface protective film is required to have the following properties: (1) the adhesive force is balanced under the low-speed peeling speed and the high-speed peeling speed; (2) has anti-pollution performance; (3) has excellent antistatic performance.
However, it is very difficult to satisfy the required performances of the adhesive agent layer constituting the surface protective film, even if the individual required performances of (1) to (3) described above can be satisfied, and at the same time, all the required performances of (1) to (3) required for the adhesive agent layer of the surface protective film can be satisfied.
In order to solve such problems, for example, (1) adhesion is balanced between a low peeling speed and a high peeling speed, (2) anti-contamination performance is provided, and (3) excellent anti-static performance is provided.
With respect to (1) the balance of the adhesive force at a low peeling speed and a high peeling speed, in an acrylic adhesive layer obtained by crosslinking a copolymer of an alkyl (meth) acrylate having an alkyl group having 7 or less carbon atoms and a carboxyl group-containing copolymerizable compound as a main component with a crosslinking agent, when the adhesive is bonded for a long time, there is a problem that the adhesive moves toward the adherend and adheres to the adherend, or the adhesive force to the adherend is greatly increased with time. In order to avoid this problem, a technique is known in which an adhesive agent layer is provided in which a copolymer of an alkyl (meth) acrylate having an alkyl group with 8 to 10 carbon atoms and a copolymerizable compound having an alcoholic hydroxyl group is used and the copolymer is crosslinked using a crosslinking agent (patent document 1).
In addition, there has been proposed a method of providing an adhesive layer in which a copolymer of a small amount of alkyl (meth) acrylate and a carboxyl group-containing copolymerizable compound is blended with the same copolymer, and the resultant is crosslinked with a crosslinking agent. However, when these are used for surface protection of a plastic sheet or the like having a low surface tension and a smooth surface, there are problems that a peeling phenomenon such as floating occurs due to heating at the time of processing or storage, and that removability is poor at the time of high-speed peeling in the field of manual operation.
In order to solve these problems, an adhesive composition has been proposed which comprises a) 100 parts by weight of an alkyl (meth) acrylate containing an alkyl (meth) acrylate having 8 to 10 carbon atoms as a main component, 1 to 15 parts by weight of b) a carboxyl group-containing copolymerizable compound and 3 to 100 parts by weight of c) a vinyl ester of an aliphatic carboxylic acid having 1 to 5 carbon atoms as a main component to form a copolymer of a monomer mixture, and a crosslinking agent having an equivalent weight or more to the carboxyl group of the component b) is blended into the copolymer (patent document 2).
The pressure-sensitive adhesive composition described in patent document 2 is free from a peeling phenomenon such as floating at the time of processing or storage, has a small increase in adhesive strength with time, is excellent in removability, can be remounted with a small force even when stored for a long period of time, particularly in a high-temperature atmosphere, does not cause adhesive residue on an adherend at this time, and can be remounted with a small force even when peeled at a high speed.
However, in the adhesive composition described in patent document 2, since the gel fraction of the adhesive layer in examples 1 to 3 is 90%, unpolymerized monomers or oligomers are easily eluted from the copolymer. Patent document 2 does not describe antistatic performance and anti-staining performance, and when a material that is likely to cause peeling static electricity is used as an adherend, there is a problem that it is difficult to produce an adhesive layer having excellent antistatic performance and anti-staining performance.
Further, as to (2) having anti-contamination property, disclosed is an adhesive composition containing: 100 parts by mass of a (meth) acrylic copolymer having a weight average molecular weight of 10 to less than 100 million, the (meth) acrylic copolymer being composed of 0 to less than 0.5 parts by mass of a carboxyl group-containing monomer, 0.6 to 9 parts by mass of a hydroxyl group-containing (meth) acrylic monomer, and 99.4 to 90.5 parts by mass of a (meth) acrylic ester monomer; and 0.1 to 5 parts by mass of a carbodiimide-based crosslinking agent (patent document 3).
The adhesive composition described in patent document 3 is characterized in that a carbodiimide-based crosslinking agent is used as a crosslinking agent for a (meth) acrylic copolymer having a specific composition. This makes it possible to form a crosslinked structure in the adhesive layer that can follow shrinkage caused by pressure and temperature during the autoclave treatment. Therefore, the adhesive layer formed using the adhesive composition described in patent document 3 can suppress and prevent foaming even under high-temperature and high-pressure conditions (at the time of autoclave treatment), and is excellent in anti-contamination performance and transparency.
However, the adhesive composition described in patent document 3 has improved anti-contamination performance, but fails to achieve both excellent adhesion performance and antistatic performance, and there remains a problem that needs to be further solved.
Further, regarding (3) having excellent antistatic performance, as a method for imparting antistatic property to the surface protective film, a method of kneading an antistatic agent into the base film, and the like are known. Examples of the antistatic agent include (a) various cationic antistatic agents having a cationic group such as a quaternary ammonium salt, pyridinium, and primary to tertiary amino groups; (b) anionic antistatic agent with sulfonate base (スルホン salt), sulfate base (エステル salt), phosphate base (リン acid エステル salt), phosphonate base (ホスホン acid salt) and other anionic groups; (c) amphoteric antistatic agents such as amino acids and amino sulfates; (d) nonionic antistatic agents such as aminoalcohols, glycerols, and polyethylene glycols; (e) a polymer type antistatic agent obtained by polymerizing the above antistatic agent in a high molecular weight (patent document 4).
However, although the surface protective film described in patent document 4 has been described about imparting antistatic performance to an adherend in relation to adhesion of dust, there is no description of a method of achieving both excellent adhesion performance and stain resistance, and there remains a problem that needs to be further solved.
In addition, in recent years, it has been proposed to directly contain an antistatic agent in an adhesive layer, instead of containing an antistatic agent in a base film or applying an antistatic agent to the surface of a base film. For example, an antistatic pressure-sensitive adhesive composition is disclosed, which is characterized by comprising a salt of an anion containing a fluoro group and a sulfonyl group dispersed in a state dissolved in a polyether ester plasticizer containing a polyether group in the main chain (patent document 5).
With respect to the adhesive composition described in patent document 5, it is disclosed that a plasticizer composed of the following ester is used as the plasticizer: an ester of a monocarboxylic acid or a dicarboxylic acid having a saturated or unsaturated acyclic hydrocarbon group and an alcohol having an acyclic hydrocarbon group having 1 to 20 carbon atoms; or an ester in which an unsaturated group in the unsaturated acyclic hydrocarbon group is epoxidized. Consider that: by making such a monocarboxylic acid or dicarboxylic acid having a saturated or unsaturated acyclic hydrocarbon group have a carbon number close to the carbon number of the acrylic monomer constituting the acrylic copolymer for the adhesive layer, compatibility in the antistatic adhesive composition becomes good, and the plasticizer is appropriately retained in the plasticizer acrylic antistatic adhesive composition, so bleeding is suppressed.
However, although the antistatic adhesive composition described in patent document 5 discloses a technique for improving antistatic performance and bleeding, it does not describe an adhesive composition having excellent adhesive performance such as balance of adhesive force at a low peeling speed and a high peeling speed, and there remains a problem in that an adhesive composition having excellent adhesive performance is obtained.

In order to prolong the storage life of the adhesive composition and improve the storage stability, the weight part ratio of (E)/(D) is preferably 70-1000, more preferably 70-700, and particularly preferably 70-300. Here, the weight part ratio of (E)/(D) is a value obtained by dividing the weight part of (E) by the weight part of (D).
The adhesive composition of the present embodiment may further contain (H) a polyether-modified siloxane compound as an optional component. (H) The polyether-modified silicone compound is a silicone compound having a polyether group, except for having a general siloxane unit [ -SiR ]1 2-O-]In addition, it has siloxane units [ -SiR ] with polyether groups1(R2O(R3O)nR4)-O-]. Here, R1Represents one or more alkyl or aryl groups, R2And R3Represents one or more alkylene groups, R4Represents one or two or more kinds of alkyl groups, acyl groups, or the like (terminal groups). The polyether group includes polyoxyethylene [ (C)2H4O)n]Or polyoxypropylene [ (C)3H6O)n]And the like. In the siloxane unit having a polyether group, the end of the polyether group may be an OH group (R in the above formula (1))4=H)。
(H) The polyether modified siloxane compound is preferably a polyether modified siloxane compound with an HLB value of 6-12.

The HLB value refers to, for example, a hydrophilic-lipophilic balance value (ratio of lipophilic to hydrophilic) specified in JIS K3211 (surfactant terminology) and the like.
The polyether-modified siloxane compound can be obtained, for example, by: an organic compound having an unsaturated bond and a polyoxyalkylene group is grafted to the main chain of a polyorganosiloxane having a silicon hydride group by a hydrosilylation reaction. Specific examples thereof include dimethylsiloxane-methyl (polyoxyethylene) siloxane copolymers, dimethylsiloxane-methyl (polyoxyethylene) siloxane-methyl (polyoxypropylene) siloxane copolymers, and dimethylsiloxane-methyl (polyoxypropylene) siloxane polymers.

(H) The polyether-modified siloxane compound preferably has a weight average molecular weight of 10000 or less. From the viewpoint of compatibility with acrylic polymers, although compatibility is better when the HLB value is low and the molecular weight is low, excellent antistatic properties can be obtained even when the HLB value is high and the compatibility with polymers is slightly low in the case of polyether-modified silicone compounds having a low molecular weight.
The pressure-sensitive adhesive composition of the present embodiment is not limited to the above additives, and may be appropriately blended with known additives such as a surfactant, a curing accelerator, a plasticizer, a filler, a curing retarder, a processing aid, an antioxidant, and an antioxidant. These additives can be used singly or in combination of 2 or more.
The adhesive composition of the present embodiment is suitable as an adhesive composition for a surface protective film to be attached to a protective layer of a polarizer of a polarizing plate. Here, the protective layer of the polarizer of the polarizing plate may be one selected from the group consisting of a TAC-based film, a PMMA-based film, and a PET-based film. Here, TAC is an abbreviation for cellulose triacetate, PMMA is an abbreviation for polymethyl methacrylate, and PET is an abbreviation for polyethylene terephthalate.
Further, the surface treatment applied on the surface of the protective layer of the polarizer of the polarizing plate may be one selected from the group consisting of no treatment, AG treatment, LR treatment, AR treatment, AG-LR treatment, and AG-AR treatment. Here, AG means Anti-Glare (Anti Glare), LR means Low Reflection (Low Reflection), and AR means Anti-Reflection (Anti Reflection).
In the adhesive layer obtained by crosslinking the adhesive composition of the present embodiment, the surface resistivity of the adhesive layer is preferably 1.0 × 10+12Omega/□ or less, more preferably 5.0X 10+11Omega/□ or less, particularly preferably 1.0X 10+11Omega/□ or less. When the surface resistivity is large, the performance of releasing static electricity generated when the adhesive layer is peeled from an adherend is poor. Therefore, by sufficiently reducing the surface resistivity, the peeling electrostatic voltage generated by static electricity generated when the adhesive layer is peeled from the adherend can be reduced, and the influence on the adherend can be suppressed.
In the adhesive layer obtained by crosslinking the adhesive composition of the present embodiment, the electrostatic voltage for peeling off the low refractive index layer formed using the resin composition for forming a low refractive index layer containing a fluoride is preferably ± 0.3kV or less, that is, preferably in the range of-0.3 to +0.3 kV. Examples of the fluoride used in the composition for forming a low refractive index layer include a fluorinated copolymer of one or two or more kinds of polymers selected from fluorinated olefins, fluorinated vinyl ethers, fluorinated alkyl (meth) acrylates, and the like, and a condensate of a silane compound containing a fluorinated alkyl group. In addition to the fluorinated monomer, a non-fluorinated monomer such as an olefin, a vinyl ether, or a (meth) acrylate may be copolymerized in the fluorine-containing copolymer. The low refractive index layer may be combined with a high refractive index layer or the like to constitute an antireflection layer.
When the peeling electrostatic voltage of the low refractive index layer is measured, a PMMA substrate and a TAC substrate can be used as the substrate for forming the low refractive index layer on the surface. Further, the electrostatic pressure for peeling of the adhesive layer obtained by crosslinking the adhesive composition of the present embodiment from a flat layer which is not subjected to any treatment on the surfaces of the PMMA substrate and the TAC substrate is preferably. + -. 0.3kV or less, that is, preferably in the range of-0.3 to +0.3 kV.
The anti-contamination performance after the adhesive layer is bonded to an adherend and left to stand in an atmosphere of 60 ℃ and 90% RH for 48 hours and taken out from the atmosphere for 1 day is preferably "no contamination" with respect to the surface of the adherend. Examples of the adherend include a polarizing plate in which a protective layer is laminated on a polarizer and the surface of the protective layer is subjected to a low reflection surface treatment with a fluoride-containing composition. The composition containing a fluoride for the low reflection surface treatment may be the same as or different from the resin composition for forming a low refractive index layer containing a fluoride. Examples of the protective layer include a PMMA substrate and a TAC substrate.
The adhesive layer obtained by crosslinking the adhesive composition of the present embodiment preferably has an adhesive force of 0.04 to 0.2N/25mm at a low peeling speed of 0.3m/min, an adhesive force of 2.0N/25mm or less at a high peeling speed of 30m/min, and more preferably an adhesive force of 0.2 to 1.6N/25mm at a high peeling speed of 30m/min, with respect to the adhesive force of the adhesive layer to the low refractive index layer applied to the surface of the PMMA substrate. This provides a property of reducing a change in the adhesive force due to the peeling speed, and allows rapid peeling even in the case of high-speed peeling. Further, even when the surface protective film is temporarily peeled off for re-attachment, the surface protective film can be easily peeled off from the adherend without requiring an excessive force.
The gel fraction of the adhesive layer obtained by crosslinking the adhesive composition of the present embodiment is preferably 95 to 100%, and more preferably 97 to 100%. Since the gel fraction of the adhesive layer is so high, the adhesive force does not become excessively high at a low peeling speed, elution of unpolymerized monomer or oligomer from the copolymer is reduced, and the reworkability and durability at high temperature and high humidity can be improved, and contamination of an adherend can be suppressed.
The adhesive film of the present embodiment is obtained by forming an adhesive layer obtained by crosslinking the adhesive composition of the present embodiment on one surface or both surfaces of a resin film. The surface protective film of the present embodiment is a surface protective film in which an adhesive layer obtained by crosslinking the adhesive composition of the present embodiment is formed on one surface of a resin film. The adhesive composition of the present embodiment has excellent antistatic performance, and has excellent balance of adhesive force at a low peeling speed and a high peeling speed, and further has anti-contamination performance. Therefore, the composition can be suitably used for the surface protective film of a polarizing plate.
As a base film of the adhesive layer or a release film (separator) for protecting the adhesive surface, a resin film such as a polyester film can be used.
The resin film may be subjected to an antistatic treatment and an antifouling treatment on one surface thereof which is opposite to the side on which the adhesive layer is formed. Examples of the antistatic treatment include coating or kneading of an antistatic agent. Examples of the antifouling treatment include a treatment with a silicone-based release agent, a fluorine-based release agent, a coating agent, silica fine particles, and the like. The surface of the release film on the side to be bonded to the adhesive surface of the adhesive layer may be subjected to release treatment using a silicone-based, fluorine-based, or long chain alkyl-based release agent.
Further, an optical film with an adhesive layer can be obtained by laminating an adhesive layer obtained by crosslinking the adhesive composition of the present embodiment on at least one surface of an optical film. Examples of the optical film include a polarizing film, a retardation film, an antireflection film, an anti-glare (anti-glare) film, an ultraviolet absorbing film, an infrared absorbing film, an optical compensation film, and a brightness enhancement film. Examples of devices to which the optical member is applied include a liquid crystal panel, an organic EL panel, and a touch panel.
In the case of an optical surface protective film or adhesive film such as a surface protective film for a polarizing plate, the base film and the adhesive layer preferably have sufficient transparency.

The obtained measurement sample was peeled at a low speed (0.3m/min) or a high speed (30m/min) in a 180 ° direction using a tensile tester, and the peel strength measured was taken as the adhesive force.
Here, the protective layer of the polarizer is one selected from the group consisting of Triacetylcellulose (TAC), Polymethylmethacrylate (PMMA), and polyethylene terephthalate (PET).
In addition, a low reflection surface treatment was applied to the surface of the protective layer of the polarizer of the LR polarizing plate and the AG-LR polarizing plate using a composition containing a fluoride.
< test method of surface resistivity >
After curing the surface protective film and before bonding it to the polarizing plate, the release film was peeled off to expose the adhesive layer, and the surface resistivity of the adhesive layer was measured using a resistivity meter HIRESTAUP-HT450 (manufactured by Mitsubishi Chemical analytical hc.
< test method of Peel Electrostatic Voltage >
The release film was peeled off, and the surface protective film with the adhesive layer exposed was bonded to a polarizing plate having a low refractive index layer formed by using a composition for forming a low refractive index layer containing a fluoride on the surface to be bonded. A voltage (electrostatic voltage) generated by electrification of an adherend when the surface protective film is peeled at 180 ℃ at a stretching speed of 30m/min is measured using high-precision electrostatic inductors SK-035 and SK-200 (manufactured by KEYENCE CORPORATION), and the maximum value of the measured values is defined as a peeling electrostatic voltage.
< test method of anti-contamination Property >
A polarizing plate subjected to Low Reflection (LR) surface treatment was bonded to one surface of a glass plate via an adhesive layer (double-sided adhesive tape) by using a bonding machine, and then a surface protective film was bonded to the surface of the polarizing plate by using a bonding machine, after the polarizing plate was bonded to an adherend, the polarizing plate was left to stand in an atmosphere of 60 ℃ and 90% RH for 48 hours, the surface protective film was removed from the atmosphere for 1 day, and the state of contamination of the surface of the polarizing plate was visually observed.
The evaluation results of the surface protective films of examples 1 to 6 and comparative examples 1 to 3 are shown in Table 3."surface resistivity" is determined by mixing "m.times.10+n"mE + n" (where m is an arbitrary real number and n is a positive integer) is used.
The column "peeling electrostatic voltage" indicates the material (TAC or PMMA) and surface treatment (Plain or AG-LR) of the protective layer of the polarizer used in the test. "surface treated" Plain refers to untreated. The column "anti-contamination performance" also refers to the material (PMMA) and surface treatment (AG-LR) of the protective layer of the polarizer used in the test.
[ Table 3]
The surface protective films of examples 1 to 6 had an adhesive force of 0.04 to 0.2N/25mm at a low peeling speed of 0.3m/min and an adhesive force of 2.0N/25mm or less at a high peeling speed of 30m/min, respectively, to a polarizing plate as an adherend, and were excellent in adhesive performance.
In addition, the surface resistivity of the adhesive layer of the surface protective films of examples 1 to 6 was 1.0X 10+12Omega/□ or less, the adhesive layer has excellent antistatic performance, and the peeling electrostatic pressure of the adhesive layer to the low refractive index layer formed by using the composition for forming the low refractive index layer containing fluoride is in the range of-0.3 to +0.3 kV.
Further, the surface protective films of examples 1 to 6 had a peel electrostatic voltage in the range of-0.3 to +0.3kV for the adhesive layer even for the untreated PMMA substrate and TAC substrate having no low refractive index layer, and were excellent in antistatic performance.
Further, even after the surface protective films of examples 1 to 6 were bonded to an adherend, and left to stand in an atmosphere at a temperature of 60 ℃ and a humidity of 90% RH for 48 hours and taken out from the atmosphere for 1 day, the polarizing plate to which the low reflection surface treatment was applied as the adherend was free from contamination and was excellent in the anti-contamination performance.

The surface protective film of comparative example 1 contains an antistatic agent having a melting point of more than 80 ℃. Therefore, the adhesive layer of the surface protective film of comparative example 1 had a large adhesive force, high peeling static voltage, and poor anti-contamination performance.
In addition, the surface protective film of comparative example 2 contains an antistatic agent having a melting point of more than 80 ℃. Therefore, the adhesive layer of the surface protective film of comparative example 2 had a large adhesive force, high peeling static voltage, and poor anti-contamination performance.
In addition, the surface protection film of comparative example 3 contains an antistatic agent having an anionic imide group even though the melting point is 25 to 80 ℃. Therefore, the surface protective film of comparative example 3 has high peeling static voltage against the PMMA base material and also has poor anti-contamination performance.
As described above, the surface protective films of comparative examples 1 to 3 failed to solve the technical problems of the present invention.
