the image display device, substantially no bubbles are formed in the interface. J Even in a high temperature and high humidity environment This is also the case. In addition, it can avoid the phenomenon that the surface protection layer or the touch panel is adhered to the image display unit screen or after the surface protection layer is adhered to the touch panel. In addition, since the transparent pressure-sensitive adhesive (PSA) sheet has low water absorption, it can prevent whitening from occurring in the image display device. [Embodiment] A component of a transparent PSA sheet is described, and component (A) is an alicyclic hydrocarbon resin. The resin has excellent water absorbability and is compatible with an amorphous saturated polyolefin resin such as polyisobutylene resin and can control the storage elastic modulus of the pre-cured composition at room temperature. Specifically, there may be mentioned a petroleum resin called a tackifier, a boxene resin, a rosin resin, a hydrogenated resin thereof, and a modified resin copolymerized with an aromatic resin. Tequila' alicyclic hydrocarbon resins include bismuth resin (Clearon P, Μ and K series, etc.), rosin and rosin ester resins (Foral AX, Foral 105, Pencel A, Estergum Η, Superester A series, etc.), disproportionated rosin And disproportionate 143310.doc 201023124 succinate resin (Pine Crystal series, etc.), hydrogenated dicyclopentadiene-based resin (Escorez 5300 and 5400 series, Eastotac Η series, etc.), which are based on hydrogenated resin of C5 petroleum resin, And these C5 petroleum resins are obtained by copolymerizing C5 fractions formed by thermal decomposition of naphtha (such as pentene, isoprene, pepper and 1,3-penta-diuret). The quality is based on partially weathered pentane resin (Escorez 5 600 series, etc.), hydrogenated resin based on C9 petroleum resin (Alcon P or bismuth series), which are formed by thermal decomposition of naphtha. A hydrogenated resin (I_Marv series) of a copolymerized petroleum resin of the above C5 & C9 fraction obtained by copolymerization of a C9 fraction (e.g., hydrazine, vinyl toluene, α- or β-methylstyrene), and the like. Among these polymers, in order to obtain low water absorption and transparency, it is preferred to hydrogenate the resin. Examples of the hydrogenated resin include, for example, a partially hydrogenated to fully hydrogenated resin having a different hydrogenation rate, and any of them can be used. However, from the viewpoint of obtaining water absorbability, compatibility with a binder polymer, and transparency, it is preferred to use complete hydrogenation. The alicyclic hydrocarbon resin has a softening point (the ring and ball softening point). An alicyclic hydrocarbon resin having any ring and ball softening point can be used depending on the pressure-sensitive adhesiveness, the operating temperature, and the ease of manufacture of the composition. Generally, the ring and ball softening point can be used at about 50 to 200 ° C, or about 70 to 150. (: Between. The weight average molecular weight of the alicyclic hydrocarbon resin may generally be between about 2 Torr and 5 Torr, and may be particularly suitable between about 500 and 3,000. Within these ranges, it may be lowered The storage elastic modulus at the pasting temperature, and the compatibility with the amorphous polyether hydrocarbon can be obtained. 143310.doc 201023124 In the transparent pressure-sensitive adhesive sheet of the present invention, the alicyclic hydrocarbon resin can be saturated in different proportions and amorphous. The polyolefin is mixed. Usually, the saturated polyolefin is preferably mixed at a lower limit content of 10 parts by mass or 20 parts by mass and an upper limit content of 200 parts by mass or 150 parts by mass with respect to 100 parts by mass of the alicyclic hydrocarbon resin. Sub-(B) (amorphous polyolefin) is a polyolefin which does not substantially contain a carbon-carbon double bond or a triple bond. Among the carbon·carbon bonds contained in the saturated polyolefin, 90〇/〇 or more is a single Examples of the saturated polyolefin include polyisobutylene, poly-α-olefin, ethylene propylene copolymer, ethylene α-olefin copolymer, propylene α_dilute hydrocarbon copolymer, hydrogenated polybutadiene, and a block thereof with styrene. Copolymers and the like. They may be used alone or in two Use in combination or more. The non-ruthenium polymer refers to a polymer with a very low crystallinity or inability to enter a crystalline state. In an amorphous polymer, the glass transition temperature can be measured, but the melting point cannot be measured. When an amorphous polymer is used, there is no decrease in transparency due to crystallization. Furthermore, 'more specifically' is a block copolymer having a saturated polyolefin block and an aromatic ethylene φ group monomer block (hereinafter referred to as "Block copolymer" is preferred as the amorphous saturated polyolefin. The block copolymer has a first block comprising a polyolefin substantially free of carbon-carbon double or triple bonds, and comprises an aromatic vinyl group. a second block of monomers. Among the carbon-carbon bonds contained in the saturated polyolefin block, 90 〇/〇 or more are single bonds. Examples of the aromatic vinyl monomer include styrene, p-A. Styrene, α-methylstyrene, rhodium and the like. These may be used singly or in combination of two or more. Examples of the block copolymer include, for example, styrene-ethylene-propylene-benzene Ethylene block copolymer, stupid ethylene-ethylene-propylene Copolymer, styrene_ethylene_butylene-styrene embedded 143310.doc •9·201023124 segment copolymer and the like. Among them, saturated polyisobutylene is preferred. Polyisobutylene contains poly a resin of an isobutylene skeleton. The polyisobutylene resin can be made only by isoprene, isoprene and n-butene in the presence of a Lewis acid catalyst such as chlorinated and trifluoromethane. Or prepared by polymerization of isoprene or butadiene. Specially known & 'The trademarks of the polyisobutylene resin are known as: Vistanex (Exxon Chemical Company), Hycar (Goodrich Company), 〇ppan〇i (BASF Corporation), JSR butyl (Japan Synthetic Rubber Co., Ltd.), and the like. The amorphous saturated polyolefin used in the present invention is compatible with an alicyclic hydrocarbon resin, and thus can form a Transparent film. Since the saturated polyolefin has a low surface energy, it can be easily coated on the adherend when it is used as an adhesive, and voids are not easily generated in the interface. Further, since it has low water absorbency, it is suitable as a matrix resin for a sheet material. The weight average molecular weight of the amorphous saturated polyolefin (molecular weight according to polystyrene obtained by the Gpc method) is about 1 Torr or more and 2,000 Å or less, especially about 1 Torr. 〇〇〇 or more and 1, face, just or less. Within this range, fluidity can be obtained and sufficient heat resistance can be maintained. The third component (C) (curable resin) can increase the fluidity of the composition before curing and the wettability to the adherend, and can also follow the irregular surface, thereby preventing the liquid positive display from being produced. Display evenly. In addition, curing can enhance the strength of retention. It is also possible to control the physical properties after curing by the amount and type of addition to achieve the desired physical properties. The curable tree sap (C) can be any thermosetting resin and radiation (light curing 143310.doc 201023124 resin. Examples of curable resin (liquid monomer and / or merging polymer) include in the industry is called A substance which cures an acrylic compound.

Φ The curable acrylic compound usually contains a (meth) acrylonitrile group and has a molecular weight of 70. Up to 700, and in one embodiment from 8 to 6 Å. It typically comprises an acrylate or methacrylate. Examples of photocurable acrylic compounds include those described in the following two paragraphs: Monofunctional acrylic monomers Examples include (meth) acrylates containing a linear alkyl group such as: lauryl (meth) acrylate, cetyl (meth) acrylate (n-C16) (wherein η" means "positive (straight chain)" type, and "ci6" does not represent 16 carbon atoms), (mercapto) stearyl acrylate (n-C18), (meth) propylene acid aralkyl ester ( n-C20) and (fluorenyl) behenyl acrylate (n-C22); and (meth) acrylate containing a branched alkyl group, such as: (meth)acrylic acid 2-ethyl hexyl hexyl ester, (meth)acrylic acid isooctyl vinegar, (meth)acrylic isophthalic acid vinegar, (mercapto)isodecyl acrylate, (decyl)isododecyl vinegar, (decyl)isotridecyl acrylate, ( Isomyristyl methyl methacrylate, isocetyl (meth) acrylate (iso-C16), isostearyl acrylate (iso-ci8), 2-octyl-12 (fluorenyl) acrylate Carbamate (iso-C2〇).

It is also possible to use a polyhydric alcohol acrylate 'for use in an acrylonitrile monomer which is oligomerically polymerized via an amino phthalate bond. Mixtures can also be used. In the above-mentioned usable examples, a (fluorenyl) acrylate resin usually having an alicyclic skeleton of a long chain or 9 or more carbons is preferred. In general, photocurable resins containing (meth)acrylonyl or glycidyl groups have a relatively high polarity and are therefore extremely incompatible with saturated olefins of extremely low polarity, but these compounds can be saturated with alicyclic hydrocarbon resins. The mixture of polyolefins is compatible. In the pressure-sensitive adhesive sheet of the present invention, the (C) curable resin and (A) alicyclic hydrocarbon resin and (B) amorphous saturated polyolefin may be mixed in various ratios. In general, the content of the component (C) may be in the range of 1 Å to 2 Å by mass, and more preferably 50%, based on 100 parts by mass of the component and 10 to 2 parts by mass of the component (B).

The (D) radiation (photo) polymerization initiator may be included in an amount of from 5% to 5 parts by mass, and in some embodiments from 0.5 to 5 parts by mass. Within this range, the acrylic monomer can be preferably polymerized, and the storage stability of the resin composition can be obtained. By using the above monomer components in the above composition, the pressure-sensitive adhesive sheet obtained can obtain sufficient compliance at the time of curing before curing, and can have sufficient holding force after curing. Generally, the term "dependency" describes a case in which the PSA sheet has a sufficiently high fluidity so that there is substantially no void and separation between the surface protective layer and the PSA sheet even when the surface protective layer is uneven. . By using a transparent pressure-sensitive adhesive sheet having sufficient compliance, even when a transparent pressure-sensitive adhesive sheet is applied to a horse-like display unit screen (which has an uneven surface layer or shape: uneven layer (such as polarized light) When the board)), it can also absorb the unevenness, and the result will eliminate the uneven display in the image display device...

The turbidity value of the object is less than 2% or more , it can be judged that no whitening phenomenon occurs. In addition, the transparency of the pressure-sensitive adhesive sheet can be obtained by adhering the adhesive sheet to a transparent adhesive body (for example, a surface protective layer of an image display device). The composition has a total light transmittance (JIS κ 7361) of 90 ° / or higher in the spectrum of visible light wavelength.

Up to 4, an image display device including the above-described pressure sensitive two sheets is described. The image display device comprises a transparent pressure-sensitive adhesive sheet and a surface and a transparent pressure-sensitive adhesive sheet contained therein to reduce the internal residual stress of the transparent. The image display unit is not particularly limited, and examples thereof include an image- or backlight-type liquid crystal display unit, a plasma display unit, an (el) '4' device, and an image display unit for electronic paper. On the display surface of the image display, other layers (which may be one or more layers) may be provided. 143310.doc • 16 - 201023124 Polarizer (which sometimes has an irregularly shaped surface). Moreover, the touch panel described below may be present on the display surface of the image display unit. When applied to an image display device, the surface protective layer acts as a layer on the outermost surface. The facet protective layer is composed only of a polymer film, a glass plate or the like, or may be composed of a plurality of layers formed together with other layers. The surface protective layer is not particularly limited as long as it is a film which is generally used as a protective film or the like of an image display device, and the Φ surface protective layer may be, for example, an acrylic resin film (e.g., polymethyl methacrylate ( PMMA)), polycarbonate resin film or glass plate. The thickness of the film or glass sheet is not limited, but is usually between 〇1 and 5〇1111. In the case where the surface protective layer is a laminate composed of a plurality of layers, a layer body imparting such functions or properties such as abrasion resistance, scratch resistance, stain resistance, antireflection and antistatic properties may be used. It is disposed on the viewer side of the image display device. The layer for imparting abrasion resistance and scratch resistance can be formed by coating a curable resin composition which can form a hard coat layer and curing the coating layer. For example, a coating comprising a partial condensation reaction product of a mixture of decane consisting of an alkyltrialkoxysilane (which is a major component) and a colloidal cerium oxide is coated, followed by heating. The cured film is cured to form a cured film, or a coating containing a polyfunctional acrylate as a main component is coated, and the coating film is irradiated with ultraviolet light, whereby a cured film can be formed. Further, in order to secure the stain resistance, a resin layer containing an organic cerium compound or a fluorine-based compound can be formed. Further, in order to obtain antistatic properties, a resin layer containing a surfactant or conductive fine particles can be formed. Preferably, the layer imparting such functions or properties does not inhibit the transparency of the surface protective layer and is preferably as thin as possible within the scope in which this function can be achieved. The thickness of the layer imparted to the function or property is not limited, but is usually between 〇 5 and 1 〇 μηι.
