Description
Technical Field
The invention relates to an adhesive composition, an adhesive layer, an optical film with the adhesive layer and a display device.
Background
In recent years, liquid crystal display devices have been used in a wide variety of applications such as in-vehicle applications, outdoor equipment, and personal computers. An adhesive layer formed of the adhesive composition adheres the polarizing plate to a liquid crystal cell (glass substrate) of a liquid crystal display device. However, since the polarizing plate has a property of stretching in a high-temperature environment, the polarizing plate may be peeled off from the glass substrate. In addition, if the release film that is not attached to the polarizing plate side is peeled off in order to attach the polarizing plate to the glass substrate, static electricity is generated. The generated static electricity may adversely affect, for example, a liquid crystal layer and a capacitance sensor of a liquid crystal display device.
In view of the above problems, patent document 1 proposes an optical pressure-sensitive adhesive composition comprising an adhesive modifier formed of an acrylic/silicone graft copolymer having a hydrolyzable silyl group, in order to impart moderate peelability and long-term stability of adhesive strength. Patent document 2 proposes an adhesive composition in which an alkoxysilyl group-containing acrylic polymer and a crosslinkable acrylic polymer are used together so as not to increase the relative dielectric constant when forming an adhesive layer. Patent document 3 proposes an optically functional film formed from an adhesive composition containing a (meth) acrylic oligomer having a hydrolyzable silyl group in order to improve durability under high-temperature and high-humidity conditions. Patent document 4 proposes an adhesive sheet containing an acrylic copolymer containing an alkylene oxide group-containing monomer as a monomer component in order to achieve antistatic performance and durability under severe environmental conditions.

Disclosure of Invention
Problems to be solved by the invention
However, the polymer of patent document 1 does not have sufficient durability because phase separation from the acrylic polymer occurs under a high temperature environment. In addition, the acrylic oligomer of patent document 2 has a weight average molecular weight (Mw) of 400 to 5000, and the acrylic polymer has little interaction with the acrylic polymer having a hydrolyzed alkoxysilyl group, and does not have sufficient durability in a high-temperature environment. The optically functional film of patent document 3 does not have sufficient durability even in a high-temperature environment. The adhesive sheet of patent document 4 has the following problems: if the adhesive composition contains a large amount of antistatic agent in order to improve antistatic properties, durability under high temperature environment may be reduced.

ADVANTAGEOUS EFFECTS OF INVENTION
According to the present invention, an adhesive composition having improved durability and antistatic properties in a high-temperature environment can be provided.
Detailed Description
Hereinafter, embodiments will be described in detail. The following embodiments are not limited to the invention as claimed in the claims, and all combinations of the features described in the embodiments are not essential to the invention. Two or more of the features described in the embodiments may be combined arbitrarily.
< adhesive composition >
The adhesive composition of the present invention contains a 1 st (meth) acrylic polymer (A), a 2 nd (meth) acrylic polymer (B), a crosslinking agent (C), and an antistatic agent (D).
The adhesive composition according to one embodiment contains the 2 nd (meth) acrylic polymer (B) in an amount of 1 to 50 parts by mass, preferably 2 to 25 parts by mass, based on 100 parts by mass of the 1 st (meth) acrylic polymer (a).
(1 (meth) acrylic Polymer (A))
The 1 st (meth) acrylic polymer (a) according to one embodiment contains, as constituent units, 50 to 99 parts by mass of the (meth) acrylic acid alkyl ester monomer (a 1), 1 to 50 parts by mass of the (meth) acrylic acid alkyl ester monomer (a 2), and 0.01 to 5 parts by mass of the (meth) acrylic acid ester monomer (a 3) having a reactive functional group relative to 100 parts by mass of the total amount of the (meth) acrylic acid alkyl ester monomer (a 1) and the (meth) acrylic acid alkyl ester monomer (a 2).
The "1 st (meth) acrylic polymer (a)" in the present specification refers to a polymer obtained by polymerizing a monomer component containing at least (meth) acrylic acid ester as a polymerizable monomer, and has at least a structural unit derived from (meth) acrylic acid ester. In the present specification and the like, the term "(meth) acrylic" means a term including both "acrylic" and "methacrylic". Similarly, the term "(meth) acrylate" refers to a term including both "acrylate" and "methacrylate".
Examples of the (meth) acrylic acid ester include alkyl (meth) acrylate, hydroxyalkyl (meth) acrylate, alkoxyalkyl (meth) acrylate, aralkyl (meth) acrylate, aryl (meth) acrylate, and other (meth) acrylic acid esters other than these. The (meth) acrylic acid ester is used singly in an amount of 1 or 2 or more of the above.
((meth) acrylic acid alkyl ester monomer (a 1))
The 1 st (meth) acrylic polymer (a) contains 50 to 99 parts by mass of the alkyl (meth) acrylate monomer (a 1) as a constituent unit. When the 1 st (meth) acrylic polymer (a) contains less than 50 parts by mass of the alkyl (meth) acrylate monomer (a 1) as a constituent unit, the adhesion of the adhesive layer to the substrate and the flexibility of the adhesive layer are reduced. Further, the pressure-sensitive adhesive layer is peeled off and lifted off from the substrate, and thus sufficient durability cannot be obtained. On the other hand, in the case where the 1 st (meth) acrylic polymer (a) contains more than 99 parts by mass of the alkyl (meth) acrylate monomer (a 1) as a constituent unit, the adhesion of the adhesive layer to the substrate is insufficient. Further, foaming of the adhesive layer occurs under a high temperature environment, and the antistatic property of the adhesive layer is lowered.
The alkyl group of the alkyl (meth) acrylate monomer (a 1) of one embodiment is C1 or more and C14 or less.
The alkyl (meth) acrylate monomer (a 1) includes, for example, methyl (meth) acrylate, ethyl (meth) acrylate, propyl (meth) acrylate, n-butyl (meth) acrylate, isobutyl (meth) acrylate, t-butyl (meth) acrylate, isobornyl (meth) acrylate, 2-ethylhexyl (meth) acrylate, octyl (meth) acrylate, isooctyl (meth) acrylate, isononyl (meth) acrylate, lauryl (meth) acrylate, and the like. The alkyl (meth) acrylate monomer (a 1) may be used alone of 1 or 2 or more of the above.
(alkylene oxide-containing monomer (a 2))
The 1 st (meth) acrylic polymer (a) contains 1 to 50 parts by mass, preferably 5 to 40 parts by mass of the alkylene oxide group-containing monomer (a 2) as a constituent unit. By containing the epoxy group-containing monomer (a 2) as a constituent unit in the range of the above mass parts of the 1 st (meth) acrylic polymer (a), it is possible to impart durability in a high-temperature environment and excellent antistatic performance to an adhesive layer obtained by using the antistatic agent (D) described later in combination. On the other hand, when the 1 st (meth) acrylic polymer (a) contains the alkylene oxide group-containing monomer (a 2) as a constituent unit outside the above-mentioned mass part range, it is difficult to achieve both excellent antistatic performance and durability under severe conditions in the formed adhesive layer.
The alkylene oxide group-containing monomer (a 2) is represented by the following general formula (1).
(in the general formula (1), R 1 Is a hydrogen atom or methyl group, R 2 Is any one of a hydrogen atom, an alkyl group, an aralkyl group or an aryl group, and n=an integer of 2 to 9. )
The alkylene oxide group-containing monomer (a 2) includes, for example, phenoxydiglycol acrylate, methoxytriethylene glycol acrylate, methoxypolyethylene glycol #400 methacrylate, phenoxytriethylene glycol acrylate, nonylphenoxypolyethylene glycol acrylate, and the like. The alkylene oxide group-containing monomer (a 2) is used alone in an amount of 1 or more than 2 kinds.
((meth) acrylate monomer (a 3) having a reactive functional group)
The 1 st (meth) acrylic polymer (a) contains, as a constituent unit, 0.01 to 5 parts by mass, preferably 0.01 to 3 parts by mass of a (meth) acrylate monomer (a 3) having a reactive functional group, based on 100 parts by mass of the total amount of the alkyl (meth) acrylate monomer (a 1) and the alkylene oxide-containing monomer (a 2). By containing the (meth) acrylic acid ester monomer (a 3) having a reactive functional group which reacts with the crosslinking agent (C) described later as a constituent unit in the above-described range of parts by mass of the (meth) acrylic polymer (a), an adhesive layer excellent in durability under a high-temperature environment can be formed.
On the other hand, when the 1 st (meth) acrylic polymer (a) contains the (meth) acrylate monomer (a 3) having a reactive functional group as a constituent unit in a smaller amount than the above-mentioned range by mass, the cohesive force of the adhesive layer is reduced, and the adhesive layer foams in a high-temperature environment. In addition, when the 1 st (meth) acrylic polymer (a) contains a (meth) acrylate monomer (a 3) having a reactive functional group in an amount larger than the above-mentioned range of parts by mass as a constituent unit, there is a concern that the adhesion of the adhesive layer to the substrate is impaired and peeling may occur, which is not preferable.
The reactive functional group of the (meth) acrylate monomer (a 3) having a reactive functional group of one embodiment is at least any one of a hydroxyl group, an epoxy group, and a nitrogen-containing group.
Here, a transparent conductive layer (a thin film layer (such as an ITO layer) formed of an oxide semiconductor) may be formed on a glass substrate of a liquid crystal panel. The transparent conductive layer has a function as an antistatic layer for preventing malfunction caused by static electricity and a function as a sensor electrode of the capacitive touch screen. When the 1 st (meth) acrylic polymer (a) contains the (meth) acrylate monomer (a 3) having a carboxyl group as a constituent unit, the transparent conductive layer may be corroded or damaged by the adhesive composition. Therefore, the 1 st (meth) acrylic polymer (a) may be selected according to the use of the adhesive composition, as long as it contains the (meth) acrylate monomer (a 3) having a carboxyl group as a constituent unit.
The (meth) acrylate monomer (a 3) having a reactive functional group includes, for example: hydroxy-containing (meth) acrylate monomers such as 2-hydroxyethyl (meth) acrylate and 4-hydroxybutyl (meth) acrylate, carboxyl-containing monomers such as (meth) acrylic acid and beta-carboxyethyl (meth) acrylate, epoxy-containing monomers such as glycidyl (meth) acrylate and 4-hydroxybutyl (meth) acrylate glycidyl ether, and amide-based monomers such as (meth) acrylamide and dimethylaminopropyl (meth) acrylamide. The (meth) acrylate monomer (a 3) having a reactive functional group is used alone in an amount of 1 or more than 2 kinds of the above.
(physical Properties)
The weight average molecular weight (GPC measurement, standard polystyrene conversion) of the 1 st (meth) acrylic polymer (a) of one embodiment is 30 to 350 ten thousand, preferably 120 to 250 ten thousand. When the weight average molecular weight of the 1 st (meth) acrylic polymer (a) is less than 30 ten thousand, sufficient durability cannot be imparted to the adhesive layer. On the other hand, when the weight average molecular weight of the 1 st (meth) acrylic polymer (a) exceeds 350 ten thousand, the viscosity of the 1 st (meth) acrylic polymer (a) becomes very high, and thus the coatability of the adhesive composition is deteriorated.
The 1 st (meth) acrylic polymer (a) can be produced by usual solution polymerization, bulk polymerization, emulsion polymerization, suspension polymerization, and the like. It is particularly preferable to produce the 1 st (meth) acrylic polymer (a) by solution polymerization using the 1 st (meth) acrylic polymer (a) which can be obtained in the form of a solution. Thus, the 1 st (meth) acrylic polymer (a) in a solution state can be directly used for producing the adhesive composition of the present invention.

The 2 nd (meth) acrylic polymer (B) can be produced by usual solution polymerization, bulk polymerization, emulsion polymerization, suspension polymerization, and the like. It is particularly preferable to produce the 2 (meth) acrylic polymer (B) by solution polymerization using the 2 (meth) acrylic polymer (B) which can be obtained in the form of a solution. Thus, the 2 nd (meth) acrylic polymer (B) in a solution state can be directly used for producing the adhesive composition of the present invention. The solvent used for the solution polymerization includes, for example, organic solvents such as ethyl acetate, toluene, n-hexane, acetone, methyl ethyl ketone, and the like.
(polymerization initiator)
The polymerization initiator used for polymerizing the above (b 1) to (b 3) and other monomers includes conventionally known oil-soluble organic peroxides, oil-soluble azo compounds, and the like, similarly to the case of producing the 1 st (meth) acrylic polymer (a). The oil-soluble polymerization initiator is preferably an oil-soluble azo compound. The oil-soluble polymerization initiator may be used singly or in an amount of 1 or more than 2.
(chain transfer agent)
In order to adjust the molecular weight of the 2 nd (meth) acrylic polymer (B), a conventionally known chain transfer agent may be suitably used in the same manner as in the production of the 1 st (meth) acrylic polymer (a). The chain transfer agent includes thiols, alpha-methylstyrene dimer, etc., and 1 or 2 or more of the above may be used. On the other hand, the 2 nd (meth) acrylic polymer (B) may be produced without using a conventionally known chain transfer agent.

When the blending amount of the crosslinking agent (C) is less than the range of the above parts by mass, there is a concern that the cohesive force of the adhesive layer is reduced and the adhesive layer foams under the high temperature durability condition. On the other hand, when the blending amount of the crosslinking agent (C) exceeds the above range of parts by mass, there is a possibility that the cohesive force of the adhesive composition is excessive and the adhesive composition may cause peeling of the adhered optical film, which is not preferable.
The isocyanate compound is a polyisocyanate compound having 2 or more isocyanate groups in 1 molecule. The polyisocyanate compound includes, for example, an adduct of pentamethylene diisocyanate, hexamethylene diisocyanate, xylylene diisocyanate, toluene diisocyanate, isophorone diisocyanate, etc. with trimethylolpropane, etc., an isocyanurate compound, a biuret compound, etc. The polyisocyanate compound is preferably a compound of toluene diisocyanate and xylylene diisocyanate.

By containing the antistatic agent (D) in the above-described range of parts by mass of the adhesive composition, an adhesive layer that combines excellent antistatic performance with durability in a high-temperature environment can be realized. When the pressure-sensitive adhesive composition contains the antistatic agent (D) in a smaller amount than the above-mentioned range, excellent antistatic performance cannot be imparted to the pressure-sensitive adhesive layer, which is not preferable. On the other hand, when the pressure-sensitive adhesive composition contains more antistatic agent (D) than the above-mentioned range of parts by mass, the cohesive force of the pressure-sensitive adhesive layer may be reduced, and the durability may be affected, which is not preferable.
The antistatic agent (D) of one embodiment is a compound containing either fluorine or silicon (wherein M is an alkali metal and is excluded + [(FSO 2 ) 2 N] - The case of the indicated compounds).

(other additives)
The adhesive composition may further contain a silane coupling agent (E). On the other hand, the adhesive composition may not contain the silane coupling agent (E). The silane coupling agent (E) may be a known silane coupling agent. The adhesive composition according to one embodiment contains the silane coupling agent (E) in an amount of 0.01 to 3.0 parts by mass, preferably 0.01 to 1.5 parts by mass, based on 100 parts by mass of the 1 st acrylic copolymer (a).
The silane coupling agent (E) includes, for example: epoxy group-containing silane coupling agents such as gamma-glycidoxypropyl trimethoxysilane, gamma-glycidoxypropyl triethoxysilane, gamma-glycidoxypropyl methyldimethoxysilane, gamma-glycidoxypropyl methyldiethoxysilane, beta- (3, 4-epoxycyclohexyl) ethyltrimethoxysilane, and epoxy group-containing alkoxysilane oligomer, gamma-mercaptopropyl trimethoxysilane, gamma-mercaptopropyl triethoxysilane, gamma-mercaptopropyl methyldimethoxysilane, gamma-mercaptopropyl methyldiethoxysilane, and mercapto-containing alkoxysilane oligomer, amino group-containing silane coupling agents such as gamma-aminopropyl trimethoxysilane, gamma-aminopropyl triethoxysilane, N-beta- (aminoethyl) -gamma-aminopropyl trimethoxysilane, N-beta- (aminoethyl) -gamma-aminopropyl triethoxysilane, N-beta- (aminoethyl) -gamma-aminopropyl methyldimethoxysilane, N-phenyl-gamma-aminopropyl trimethoxysilane, and isocyanate group-containing silane coupling agents such as gamma-isocyanatopropyl trimethoxysilane and gamma-isocyanatopropyl triethoxysilane.

The adhesive composition may further contain various additives according to the required properties required for adjusting the adhesive force and the like. Examples of the additives include terpene-based, terpene-phenol-based, coumarone indene-based, styrene-based, rosin-based, xylene-based, phenol-based, petroleum-based and other tackifying resins, antioxidants, ultraviolet absorbers, fillers, pigments and the like. The additive may be used singly or in combination of 1 or more than 2 kinds.
(surface resistivity of adhesive layer)
The adhesive layer formed from the adhesive composition of one embodiment has a surface resistivity of less than 8.0X10 8 Ω/≡, preferably less than 7.5X10 8 Ω/□。
The adhesive layer formed from the conventional adhesive composition is formed such that the surface resistivity of the adhesive layer is less than 8.0X10 8 Omega/≡and contains a large amount of antistatic agent (D). However, there is a problem in that the cohesive force of the adhesive layer is lowered and the durability of the adhesive layer is lowered in a high temperature (105 ℃ or 115 ℃) or high temperature and high humidity environment.
In contrast, in the adhesive layer formed from the adhesive composition of the present invention, by using the monomer (B3) component having an alkoxysilyl group as the monomer composition of the 2 nd (meth) acrylic polymer (B), even when a large amount of the antistatic agent (D) is contained, the durability of the adhesive layer is not lowered. However, it has been found that even in the case of an adhesive layer comprising: in the case of the 2 nd (meth) acrylic polymer (B) containing the monomer (B3) having an alkoxysilyl group and a large amount of the antistatic agent (D), the low surface resistivity (i.e., high antistatic property) of the adhesive layer cannot be achieved.
Accordingly, the inventors of the present invention found that, in the adhesive layer, it contains: in the case of the 2 nd (meth) acrylic polymer (B) containing the monomer (B3) having an alkoxysilyl group, the 1 st (meth) acrylic polymer (a) containing the monomer (a 2) containing an alkylene oxide, and a large amount of the antistatic agent (D), a low surface resistivity of the adhesive layer can be achieved. That is, in order to achieve low surface resistivity of the adhesive layer, it is important to include the antistatic agent (D) in the adhesive composition in consideration of the balance of the compounding amounts of the antistatic agent (D) and the alkoxysilyl group-containing monomer (b 3) and the alkylene oxide group-containing monomer (a 2).
According to the adhesive composition in which the balance of the blending amounts of the above components is taken into consideration, even under the severe durability conditions, an adhesive layer which does not foam from the substrate can be realized. In addition, the pressure-sensitive adhesive layer has an excellent effect of suppressing static electricity generated when peeling off a release paper or the like of the pressure-sensitive adhesive sheet and reducing the influence of static electricity on a polarizing film or the like.
The surface resistivity of the adhesive layer was measured using a high resistivity meter (trade name: hibeta-UX MCP-HT 450) manufactured by Mitsubishi Chemical Analytech Co., ltd. Specifically, an adhesive layer having a thickness of 20 μm was formed on a release film to prepare an evaluation sample. After the evaluation sample was cut into a measurement size, the release film was peeled off. Then, the evaluation sample was stored in a constant temperature and humidity chamber having a temperature of 23.+ -. 2 ℃ and a humidity of 50.+ -. 5% RH. The surface resistivity of the sample was evaluated by measurement using a high resistivity meter at high temperature and high humidity.
< adhesive layer >
The adhesive layer formed from the adhesive composition of the present invention is obtained by applying a predetermined amount of the adhesive composition onto a release film, and curing and drying the adhesive composition. The thickness of the adhesive layer of one embodiment is preferably 10 to 50 μm, more preferably 10 to 25 μm. When the thickness of the pressure-sensitive adhesive layer is within the above range, a pressure-sensitive adhesive sheet having excellent durability and antistatic properties, which will be described later, can be formed. Then, the adhesive sheet of the present invention is used to adhere a polarizing plate to a glass substrate of a liquid crystal display device, for example, whereby the glass substrate and the polarizing plate can be firmly adhered. The pressure-sensitive adhesive layer can bond the adherend formed of any organic material, the adherend formed of any inorganic material, or the adherend formed of any organic material to the adherend formed of any inorganic material.

An adhesive sheet having an adhesive layer formed of the adhesive composition of one embodiment adheres a polarizing plate to an adherend (e.g., glass). The adhesive sheet has a release film and an adhesive layer formed on the release film. One surface of the adhesive layer is adhered to the polarizing plate, and the other adhesive surface is adhered to a release film or the like. When the release film or the like attached to the other adhesive surface of the adhesive layer is peeled off, the adhesive sheet of the present invention is excellent in antistatic performance, and therefore, static electricity generated when the release film is peeled off from the adhesive surface can be suppressed. Then, after the release film or the like is peeled off, the other adhesive surface of the adhesive layer is bonded to, for example, the outer surface of the glass substrate. Thus, adverse effects on components (e.g., liquid crystal layer, capacitive sensor) of the liquid crystal display device caused by the generation of static electricity can be reduced.
Further, the adhesive sheet of the present invention has the above-described excellent antistatic property and also has an effect of excellent durability under severe environmental conditions. For example, in a severe environment at high temperature (105 ℃ C. Or 115 ℃) or high temperature and high humidity, the polarizing plate bonded to the glass substrate using the adhesive sheet does not peel from the glass substrate, and the adhesive layer does not foam. The polarizing plate to which the adhesive sheet of the present invention can be applied is a conventionally known polarizing plate. Examples of the polarizing plate include a polarizing plate using an untreated TAC film, a polarizing plate coated or uncoated with discotic liquid crystal, a polarizing plate using a stretched film (for example, a stretched triacetyl cellulose film, a stretched polycycloolefin film or a stretched cellulose acetate propionate film) as a base material, and the like.
The pressure-sensitive adhesive sheet having a pressure-sensitive adhesive layer formed on a release film or the like can be produced by the following steps. A release film such as a polyethylene terephthalate film (PET film) having a release agent such as a silicone resin applied to the surface thereof is coated with a predetermined amount of the adhesive composition by using a general coating apparatus (for example, a roll coating apparatus) and dried. Thus, an adhesive sheet having an adhesive layer formed on the release film can be obtained. The polarizing plate may be directly bonded to the surface of the pressure-sensitive adhesive layer on the side not in contact with the release film. Alternatively, the pressure-sensitive adhesive sheet may be stored in a state where release films are present on both sides of the pressure-sensitive adhesive layer, and the release films may be peeled off and the pressure-sensitive adhesive layer may be bonded to the polarizing plate as needed. In addition, depending on the constituent material of the adhesive composition, the adhesive layer may be formed on the release film by heat crosslinking or photo-curing with ultraviolet rays or the like.
< optical film with adhesive layer >
The optical film with an adhesive layer of the present invention comprises an adhesive layer on at least one surface of the optical film. The optical film according to one embodiment includes, for example, a plastic film such as polystyrene, a styrene-acrylic copolymer, an acrylic resin, polyethylene terephthalate, polycarbonate, polyether ether ketone, or triacetyl cellulose, an antireflection film, an electromagnetic shielding film, and the like.
< display device >
The display device of the present invention includes the optical film with an adhesive layer described above, and is, for example, a liquid crystal display device or an organic EL display. The liquid crystal display device is formed by adhering a polarizing plate, a laminate of a polarizing plate and a phase difference plate, or the like to an outer surface of a glass substrate of a liquid crystal cell (formed by sandwiching a liquid crystal component aligned in a predetermined direction with 2 glass substrates) via an adhesive layer formed of an adhesive composition. The organic EL display includes a transparent substrate (glass) on which a plurality of organic EL elements are arranged in a matrix.

TABLE 13
TABLE 14
As shown in the results of tables 10 to 14, the adhesive layers formed from the adhesive compositions of examples 1 to 20 achieved improved durability in a high temperature environment (105 ℃ C. Or 115 ℃ C.) and a high temperature and high humidity environment (85% RH) and low surface resistivity (less than 8.0X10) 8 Ω/≡). The reason for this is presumed that the adhesive compositions of examples 1 to 20 consider the antistatic agent (D) and the 2 nd (meth) acrylic polymer containing the alkoxysilyl group-containing monomer (b 3) as a constituent unit (B) And the 1 st (meth) acrylic polymer (A) containing the alkylene oxide group-containing monomer (a 2) as a constituent unit.
On the other hand, the adhesive layers formed from the adhesive compositions of comparative examples 1 to 10 failed to achieve improvement in durability and low surface resistivity (less than 8.0X10 8 Ω/□)。
Further, since the adhesive layers of examples 1 to 20 have high adhesion to the polarizing film as an example of the base material, degradation of the display quality of the display device can be suppressed.
