1 is a schematic cross-sectional view of a touch screen panel according to an embodiment of the present invention.
Hereinafter, embodiments of the present invention will be described in detail. However, this is presented as an example, by which the present invention is not limited and the present invention is defined only by the scope of the claims to be described later.
A photocurable acrylic copolymer resin of the (meth) acrylic acid ester monomer and the crosslinkable monomer of the present invention, wherein the crosslinkable monomer is a (meth) acrylate having a substituent of a C3-C10 hydroxyalkyl group, and the photocurable acrylic system Provided is a pressure-sensitive adhesive composition for a touch screen panel in which the sum of the content of the crosslinkable monomer in the total monomers constituting the copolymer resin is about 10 to about 25% by weight.
When manufacturing a touch screen panel of a display device such as a mobile or tablet PC, an adhesive film used as a bonding medium for bonding a conductive plastic film layer having a conductive layer formed on one surface and a cover window layer may be manufactured from the pressure-sensitive adhesive composition for the touch screen panel. Can be.
The pressure-sensitive adhesive composition for a touch screen panel is formed into an adhesive film by photocuring the photocurable acrylic copolymer resin, and the pressure-sensitive adhesive film is optically transparent to be applied to a touch screen panel, and has a low dielectric constant. As such, the adhesive film having a low dielectric constant is useful for applying to a touch screen panel due to increased sensitivity to touch. In addition, the pressure-sensitive adhesive film can implement a low dielectric constant at the same time while the occurrence of cloudiness is suppressed.
The (meth) acrylic acid ester monomer may be, for example, alkyl (meth) acrylate, but is not limited thereto. Alkyl of the alkyl (meth) acrylate may be linear or branched C1-C30 alkyl, specifically C6-C18 alkyl. The dielectric constant of the pressure-sensitive adhesive film prepared from the pressure-sensitive adhesive composition for a touch screen panel using an alkyl (meth) acrylate having a relatively long alkyl chain in the carbon number range can be effectively lowered.
Specifically, the (meth) acrylic acid ester monomer is methyl (meth) acrylate, ethyl (meth) acrylate, n-propyl (meth) acrylate, isopropyl (meth) acrylate, n-butyl (meth) acryl Late, t-butyl (meth) acrylate, sec-butyl (meth) acrylate, pentyl (meth) acrylate, 2-ethylhexyl (meth) acrylate, 2-ethylbutyl (meth) acrylate, n-octyl It may include one selected from the group consisting of (meth) acrylate, isooctyl (meth) acrylate, isobornyl (meth) acrylate, isononyl (meth) acrylate and combinations thereof.
The crosslinkable monomer means a monomer further comprising a functional functional group as well as a copolymerizable functional group (eg, carbon-carbon double bond) in a molecular structure.
The content of the crosslinkable monomer may be adjusted to include a hydroxyl group in an appropriate content ratio in the pressure-sensitive adhesive composition. For example, when the carbon number of the hydroxyalkyl group in the crosslinkable monomer is increased, the content ratio of the hydroxy group in the pressure-sensitive adhesive composition is relatively low, thereby increasing the content of the crosslinkable monomer.
In one embodiment, the photocurable acrylic copolymer resin may be a polymerized monomer component consisting of 100 parts by weight of the (meth) acrylic acid ester monomer and about 10 to about 25 parts by weight of the crosslinkable monomer, in another embodiment, The chemical conversion acrylic copolymer resin may be obtained by polymerizing a monomer component including 100 parts by weight of the (meth) acrylic acid ester monomer and about 10 to about 15 parts by weight of the crosslinkable monomer.
The crosslinkable monomer may be, for example, hydroxypropyl (meth) acrylate or hydroxybutyl (meth) acrylate, or may include a combination thereof.
The pressure-sensitive adhesive composition may suppress the turbidity of the pressure-sensitive adhesive film prepared from the composition by lowering the relative content of the hydroxy group in the composition by using a crosslinking monomer having a high electronegativity and polar hydroxyalkyl groups in an appropriate amount. In addition, the dielectric constant can be lowered by copolymerizing a (meth) acrylic acid ester monomer substituted with an alkyl group having a high carbon number together.
In the pressure-sensitive adhesive composition, the total amount of the crosslinkable monomer in the total monomers constituting the photocurable acrylic copolymer resin is prepared to include about 10 wt% to about 25 wt%, thereby realizing excellent touch sensitivity while maximizing cloudiness. It can be suppressed.
The crosslinkable monomer may further include 2-isocyanatoethyl (meth) acrylate, 3-isocyanatopropyl (meth) acrylate, 4-isocyanatobutyl (meth) acrylate, and (meth) acrylic. It may further comprise nitrogen-containing monomers such as amides, N-vinyl pyrrolidone, N-vinyl caprolactam and the like.
The pressure-sensitive adhesive composition for a touch screen panel may contain a photocurable acrylic copolymer resin in which the crosslinkable monomer is copolymerized, thereby reducing cloudiness while reducing the content of hydroxyl groups in the whole composition. For example, the pressure-sensitive adhesive composition for the touch screen panel may have a hydroxyl value of about 60 to about 100 mg KOH / g.
As such, the pressure-sensitive adhesive composition for the touch screen panel may be manufactured to have a low dielectric constant. Specifically, the dielectric constant k value measured at a frequency of 100 kHz may be 3.0 or less. The pressure-sensitive adhesive film prepared from the pressure-sensitive adhesive composition for touch screen panels having a dielectric constant in the above range is excellent in touch sensitivity.
As described above, the pressure-sensitive adhesive composition for the touch screen panel may suppress cloudiness while lowering the relative dielectric constant (for example, may be evaluated by a hydroxyl value) in the composition of the hydroxyl group.
In one embodiment, the crosslinkable monomer is composed of a monomer selected from the group consisting of hydroxypropyl (meth) acrylate, hydroxybutyl (meth) acrylate, and combinations thereof, and hydroxyethyl (meth) acrylate do not include.
The pressure-sensitive adhesive composition for a touch screen panel may further include a photoinitiator to control the degree of polymerization as a photocurable composition. The photoinitiator may be used in an amount of about 0.01 to about 10 parts by weight based on 100 parts by weight of the photocurable acrylic copolymer resin, and the type of the photoinitiator may be used to generate a radical by light irradiation to initiate a polymerization reaction. It is not limited, and may include, for example, one selected from the group consisting of a benzoin initiator, a hydroxy ketone initiator, an amino ketone initiator caprolactam, and a combination thereof.
In addition, the pressure-sensitive adhesive composition for a touch screen panel is composed of an epoxy resin, a crosslinking agent, an ultraviolet stabilizer, an antioxidant, a colorant, a reinforcing agent, a filler, an antifoaming agent, a surfactant, a plasticizer, and a combination thereof. It may further comprise one or more additives selected from the group.
In another embodiment of the present invention, it provides an adhesive film comprising a pressure-sensitive adhesive layer containing a photocurable of the pressure-sensitive adhesive composition for the touch screen panel.
The pressure-sensitive adhesive composition for a touch screen panel may be coated on a substrate layer, and then photocured by light irradiation to prepare an adhesive film. "Light irradiation" refers to the irradiation of electromagnetic waves that can affect the photoinitiator or polymerizable compound to cause a polymerization reaction, wherein the electromagnetic waves are microwaves, infrared rays, ultraviolet rays, X-rays and γ-rays, as well as α-particle beams, Particle beams such as a proton beam, a neutron beam, and an electron beam are used generically.
The method of manufacturing the pressure-sensitive adhesive film by photocuring the pressure-sensitive adhesive composition for touch screen panels is not particularly limited. For example, the pressure-sensitive adhesive film can be produced by applying the above-described composition for a touch screen panel or a coating solution prepared by adding a solvent thereto to a suitable process substrate by a known means such as a bar coater and curing. .
The curing process is carried out after sufficiently removing the bubble-inducing components such as volatile components or reaction residues contained in the pressure-sensitive adhesive composition or the coating solution, to appropriately give the crosslinking density or molecular weight, elastic modulus, etc. of the cured product, The bubbles present in the adhesive interface may be increased to prevent a problem of forming scatterers therein.
In addition, the method of curing the pressure-sensitive adhesive composition for a touch screen panel or a coating liquid thereof is not particularly limited, and for example, ultraviolet rays are irradiated to the coating layer formed by the pressure-sensitive adhesive composition for a touch panel or the coating liquid thereof, or aged under predetermined conditions ( The curing process may be performed through a aging process.
The photocuring can be carried out, for example, by UV irradiation.
UV irradiation performed for the photocuring may be performed for about 10 seconds to about 15 seconds with a metal halide lamp that is commonly used.
The amount of light irradiated with UV is preferably about 0.5 J / cm 2 to about 2.0 J / cm 2 , and more preferably about 1.0 J / cm 2 to about 1.5 J / cm 2 .
The adhesive film 12 may have a thickness of about 50 μm to about 300 μm, specifically about 100 μm to about 200 μm. By allowing the adhesive film to have a thickness in the above range, it can be applied to a thin touch panel or a touch screen, but can implement an adhesive film having excellent durability.
