[發明欲解決之課題]   [0004] 一般,於氣體障壁性薄膜具有之氣體障壁層上直接層合含有樹脂之樹脂層而構成時,由於氣體障壁層與樹脂之親和性低,故有氣體障壁層與樹脂之層間密著性產生問題之情況。尤其使用含高分子化合物且施以改質處理的氣體障壁層時,該氣體障壁層與樹脂之層間密著性多數情況較差。   [0005] 另一方面,專利文獻1中,並未針對氣體障壁層與樹脂之層間密著性進行檢討。使用如專利文獻1記載之黏著薄片密封有機EL元件時,氣體障壁層與樹脂之層間密著性低時,因水分等自兩層間浸入,而容易產生有機EL元件之發光特性降低。   又,用以密封有機EL元件所用之密封材,不僅對於氣體障壁層要求抑制水分浸入之特性,對於接著劑層(黏著劑層)亦要求該特性。   [0006] 本發明係鑑於上述情況而完成者,目的在於提供經由接著劑層之水分朝被密封物浸入的抑制效果高而具有優異之層間密著性之氣體障壁性層合體及將被密封體以該氣體障壁性層合體密封而成之密封體。 [用以解決課題之手段]   [0007] 本發明人等發現於與含高分子化合物且施以改質處理的氣體障壁層直接層合之接著劑層的形成材料的接著劑組成物中,至少含有多官能環氧化合物並且於該接著劑組成物中進而含有特定樹脂,而且將由該接著劑組成物形成之特定薄片狀物之水蒸氣透過率調整為特定值以下,可解決上述課題,因而完成本發明。   [0008] 亦即,本發明係有關下述[1]~[11]。   [1] 一種氣體障壁性層合體,其特徵係具有含高分子化合物且施以改質處理的氣體障壁層、與由含有聚烯烴樹脂(A)及多官能環氧化合物(B)的接著劑組成物形成的接著劑層,   且具有前述氣體障壁層與前述接著劑層直接層合的構成。   [2] 如上述[1]記載之氣體障壁性層合體,其中,成分(A)含有改性聚烯烴樹脂(A1)。   [3] 如上述[2]記載之氣體障壁性層合體,其中,成分(A1)為酸改性聚烯烴樹脂。   [4] 如上述[1]~[3]中任一項記載之氣體障壁性層合體,其中,前述接著劑層的80℃之儲存彈性率G’為0.3MPa以下。   [5] 如上述[1]~[4]中任一項記載之氣體障壁性層合體,其中,成分(A)的含量相對於前述接著劑組成物的有效成分之全量而言,為5~ 90質量%。   [6] 如上述[1]~[5]中任一項記載之氣體障壁性層合體,其中,成分(B)的含量相對於前述接著劑組成物所含有的成分(A) 100質量份而言,為5~200質量份。   [7] 如上述[1]~[6]中任一項記載之氣體障壁性層合體,其中,前述接著劑組成物進一步含有黏著賦予劑(C)。   [8] 如上述[1]~[7]中任一項記載之氣體障壁性層合體,其中,前述接著劑組成物進一步含有咪唑系硬化觸媒(D)。   [9] 如上述[1]~[8]中任一項記載之氣體障壁性層合體,其中,前述接著劑組成物進一步含有矽烷偶合劑(E)。   [10] 一種氣體障壁性層合體,其特徵係具有含高分子化合物且施以改質處理的氣體障壁層、與由含有多官能環氧化合物(B)且符合下述要件(I)的接著劑組成物形成的接著劑層,   且具有前述氣體障壁層與前述接著劑層直接層合的構成,   .要件(I):由前述接著劑組成物形成的厚度50μm的薄片狀物的水蒸氣透過率為200g/m2 /day以下。   [11] 一種密封體,其特徵係將有機EL元件、有機EL顯示器元件、液晶顯示器元件、或太陽能電池元件以上述[1]~[10]中任一項記載之氣體障壁性層合體進行密封而成。 [發明效果]   [0009] 本發明之氣體障壁性層合體由於經由接著劑層之水分朝被密封物浸入的抑制效果高而具有優異之層間密著性,故可成為被密封物劣化之抑制效果高的密封材。[Problems to be Solved by the Invention] [0004] In general, when a resin layer containing a resin layer is directly laminated on a gas barrier layer included in a gas barrier film, the gas barrier layer has a low affinity with the resin, and therefore has a gas barrier. When the adhesion between the layer and the resin is problematic. In particular, when a gas barrier layer containing a polymer compound and modified is used, the adhesion between the gas barrier layer and the resin is often poor. [0005] On the other hand, Patent Literature 1 does not review the adhesion between the gas barrier layer and the resin. When the organic EL element is sealed using the adhesive sheet described in Patent Document 1, when the interlayer adhesion between the gas barrier layer and the resin is low, moisture and the like are immersed from between the two layers, and the light-emitting characteristics of the organic EL element are liable to decrease. In addition, the sealing material used for sealing the organic EL element requires not only the gas barrier layer's characteristic of suppressing the penetration of moisture, but also the adhesive layer (adhesive layer). [0006] The present invention has been made in view of the above circumstances, and an object thereof is to provide a gas barrier laminate and an object to be sealed that have a high effect of suppressing the penetration of moisture into the sealant through the adhesive layer and have excellent interlayer adhesion.

[0008] That is, the present invention relates to the following [1] to [11].

[6] The gas barrier laminate according to any one of the above [1] to [5], wherein the content of the component (B) is 100 parts by mass of the component (A) contained in the adhesive composition In other words, it is 5 to 200 parts by mass. [7] The gas barrier laminate according to any one of the above [1] to [6], wherein the adhesive composition further contains an adhesion-imparting agent (C).

[11] A sealing body characterized in that an organic EL element, an organic EL display element, a liquid crystal display element, or a solar cell element is sealed with a gas barrier laminate as described in any one of the above [1] to [10] Made. [Effect of the Invention] [0009] The gas barrier laminate of the present invention has excellent interlayer adhesion due to its high inhibitory effect on the penetration of moisture through the adhesive layer into the sealed object, and thus it can be an inhibitory effect on the deterioration of the sealed object.

[0010] 本說明書中,針對較佳數值範圍(例如含量等之範圍),而階段性記載之下限值及上限值可分別獨立組合。例如由「較好為10~90,更好為30~60」之記載,亦可將「較好的下限值(10)」與「更好的上限值(60)」組合,而成為「10~60」。   [0011] [氣體障壁性層合體之構成]   本發明之氣體障壁性層合體具有使含高分子化合物且施以改質處理的氣體障壁層與由接著劑組成物形成之接著劑層,且具有前述氣體障壁層與前述接著劑層直接層合的構成。   因此,本發明之第1實施形態之氣體障壁性層合體(1)(以下亦稱為「本發明之氣體障壁性層合體(1)」)中,前述接著劑層係由含有聚烯烴樹脂(A)及多官能環氧化合物(B)的接著劑組成物形成者。   又,本發明之第2實施形態之氣體障壁性層合體(2)(以下亦稱為「本發明之氣體障壁性層合體(2)」)中,前述接著劑層係由含有多官能環氧化合物(B)且滿足下述要件(I)的接著劑組成物形成者。   .要件(I):由前述接著劑組成物形成的厚度50μm的薄片狀物的水蒸氣透過率為200g/m2 /day以下。   又,本說明書中,將「本發明之氣體障壁性層合體(1)」與「本發明之氣體障壁性層合體(2)」彙總記載為「本發明之氣體障壁性層合體」。   [0012] 本發明之氣體障壁性層合體亦可具有氣體障壁層及接著劑層以外之層,例如亦可具有基材層或剝離薄膜,舉例為例如具有以下之層構成之態樣。   .(i)依順序層合基材層/氣體障壁層/接著劑層/剝離薄膜而成之層合體。   .(ii)依順序層合剝離薄膜/氣體障壁層/接著劑層/剝離薄膜而成之層合體。   [0013] 上述(i)之態樣中,為了提高基材層與氣體障壁層之密著性,亦可如下述(iii)之態樣般,於基材層與氣體障壁層之間具有底塗層。   .(iii)依順序層合基材層/底塗層/氣體障壁層/接著劑層/剝離薄膜而成之層合體。   [0014]

此處,本發明之氣體障壁性層合體(1)具有之接著劑層由於含有多官能環氧化合物(B)且進而含有聚烯烴系樹脂(A),故可將該接著劑層之水蒸氣透過率調整為較低,可抑制經由接著劑層之水分朝被密封物之侵入。   又,本發明之氣體障壁性層合體(1)具有含高分子化合物且施以改質處理的氣體障壁層,經由本發明人等經檢討而了解僅由聚烯烴系樹脂(A)形成之接著劑層與該氣體障壁層之層間密著性差。   因此,由本發明人等積極檢討之結果,發現藉由由含有聚烯烴系樹脂(A)且含有多官能環氧化合物(B)之接著劑組成物形成之接著劑層,可提高與具有含高分子化合物且施以改質處理的氣體障壁層之層間密著性。   本發明之氣體障壁性層合體係由該見解而完成者,由於水蒸氣透過率低,可抑制經由接著劑之水分朝被密封物之侵入且具有優異之層間密著性,故而可成為被密封物劣化之抑制效果高的密封材。   [0016] 另一方面,本發明之氣體障壁性層合體(2)係適當調整接著劑層的形成材料之接著劑組成物的成分種類或含量,而調整為滿足上述要件(I)規定之厚度50μm的薄片狀物的水蒸氣透過率為200g/m2 /day以下者。   又,氣體障壁性層合體(2)具有之接著劑層之形成材料的接著劑組成物,若至少含有多官能環氧化合物(B)且滿足上述要件(I),則亦可含有聚烯烴系樹脂(A)以外之樹脂成分。   [0017] 本發明之氣體障壁性層合體(2)中,以上述要件(I)規定之厚度50μm的薄片狀物的水蒸氣透過率為200g/m2 /day以下,但較好為150 g/m2 /day以下,更好為100g/m2 /day以下。   藉由使該薄片狀物之水蒸氣透過率為200g/m2 /day以下,可抑制水分朝形成於透明基板上之有機EL元件等之被密封物內部之浸入,可有效地抑制電極或有機層劣化。   又,本說明書中,水蒸氣透過率意指藉由實施例記載之方法測定之值。   且,本發明之氣體障壁性層合體(2)具有之接著劑層與上述要件(I)所規定之薄片狀物係形成材料的接著劑組成物為相同,且前述薄片狀物規定為厚度係50μm,但前述接著劑層厚度不限制於50μm,而可根據用途適當設定。   [0018] 此處,本發明之氣體障壁性層合體(1)及(2)具有之接著劑層厚度係根據用途適當設定,但較好為2~50μm,更好為5~40μm,又更好為10~30μm。   [0019] 本發明之氣體障壁性層合體(1)及(2)具有之接著劑層的80℃之儲存彈性率G’較好為0.3MPa以下,更好為0.2MPa以下,又更好為0.1 MPa以下,再更好為0.09MPa以下。   藉由使接著劑層的80℃之儲存彈性率G’為0.3MPa以下,本發明之氣體障壁性層合體可成為凹凸追隨性優異、被密封物劣化之抑制效果高之密封材。   又,基於處理性之觀點,接著劑層的80℃之儲存彈性率G’通常為0.001MPa以上,較好為0.005MPa以上,更好為0.01MPa以上。   又,本說明書中,接著劑層之儲存彈性率G’意指藉由實施例中記載之方法測定之值。   [0020] 本發明之氣體障壁性層合體(1)及(2)具有之接著劑層較好具有熱硬化性。此等接著劑層於硬化後,接著強度極優異。   使接著劑層熱硬化時之條件並未特別限定,但加熱溫度通常為80~200℃(較好90~150℃),加熱時間通常為30分鐘~12小時(較好1~6小時)。   [0021]

Next, on the formed undercoat layer, a spin coater (manufactured by MIKASA, Inc., product name "MS-A200") was used to apply perhydropolysilazane at a rotation speed of 3000 rpm and a rotation time of 30 seconds. A coating agent (manufactured by Merck Performance Materials Co., Ltd., product name "AKUAMIKA NL110-20", solvent: xylene) having a solid content concentration of 10% by mass as a main component forms a coating film. Then, the coating film was dried at 120 ° C. for 2 minutes, and a polysilazane layer made of polysilazane with a thickness of 150 nm was formed on the undercoat layer. Next, a plasma ion implantation device was used to perform a modification treatment on the surface of the aforementioned polysilazane formed by a plasma ion implantation method under the following conditions to form a gas barrier layer having a thickness of 150 nm. (Processing conditions of plasma ion implantation). Chamber pressure: 0.2Pa. Plasma generator body: Argon. Gas flow: 100sccm. RF output: 1000W RF frequency: 1000Hz RF pulse width: 50μs. RF delay: 25n seconds. DC voltage: -6kV. DC frequency: 1000Hz DC pulse width: 5μs. DC delay: 50μs. Duty cycle: 0.5%. Processing time: 200 seconds. On the formed gas barrier layer, the formation of a gas barrier layer having a thickness of 150 nm was repeated three times in the same manner as described above to obtain a thickness of 150 nm with a thickness of 4 layers. Gas barrier film of 600 nm gas barrier layer. [4] Production of Gas Barrier Laminated Body The surface of the adhesive layer formed in the above (2) with a thickness of 12 μm and the surface of the gas barrier layer with a thickness of 600 nm of the gas barrier film produced in the above (3) was used as a heat layer. The machine was bonded and bonded at 60 ° C to produce a gas barrier laminate. [0090] Using the adhesive layers and gas barrier laminates obtained in the examples and comparative examples, the following physical property values were measured and evaluated. These results are shown in Table 1. [Water vapor transmission rate of the adhesive layer] The release film was removed from the laminate of the release film and the adhesive layer having a thickness of 50 μm produced in the examples and comparative examples, and only the aforementioned adhesive layer was used as a test. The sample was measured for the water vapor transmission rate of the adhesive layer using a gas transmission rate measuring device (manufactured by Mocon Corporation, product name "PERMATRAN"). [Storage elastic modulus G ′ of the adhesive layer] The adhesive layers formed in the examples and comparative examples were overlapped, and heated and compressed at 60 ° C. using a thermal laminator to obtain multiple layers of the adhesive layer with a thickness of 1 mm. body. The multilayer body of this adhesive layer was used as a test sample, and a viscoelasticity measuring device (product name: "Physica MCR301" manufactured by Anton Paar) was used to measure the temperature before curing at a temperature range of 23 to 150 ° C at a frequency of 1 Hz. The storage elastic modulus G 'of the multilayer body of the aforementioned adhesive layer. The measured values of the storage elastic modulus G 'at 80 ° C are shown in Table 1. [Evaluation of Interlayer Adhesiveness] The gas barrier laminates produced in the examples and comparative examples were cut to a size of 25 mm × 300 mm in width, the release film was removed, and the surface of the exposed adhesive layer was attached to a glass plate and used. A thermal laminator was pressed at 60 ° C to produce a test sample. Next, this test sample was heated at 100 ° C for 2 hours to harden the adhesive layer, and then left at 23 ° C for 24 hours. Furthermore, when the gas barrier layered laminate was peeled from the glass plate under a condition of a peeling angle of 180 ° after being left for 168 hours in an environment with a temperature of 85 ° C and 85% RH (relative humidity), it was confirmed whether the adhesive layer was tacky. On the glass plate, the adhesion between the gas barrier layer and the adhesive layer was evaluated by the following criteria. A: No adhesion of the adhesive layer to the glass plate was confirmed. F: Adhesion of the adhesive layer to the glass plate was confirmed. [Evaluation of Concave and Convexity] On a glass substrate, a small piece of polyethylene terephthalate having a thickness of 10 μm was left as a pseudo device. Next, the stripped film of the gas barrier laminates produced in the examples and comparative examples was removed, and the exposed adhesive layer completely covered the pseudo-device on the glass substrate, and the laminate was laminated on the glass substrate and the pseudo-device, using a hot layer. The combined machine was sealed at 80 ° C, followed by pressure treatment at 80 ° C and 0.5 MPa for 20 minutes. In addition, the adhesive layer was hardened by heating at 100 ° C for 2 hours. Using an optical microscope, the interface between the pseudo-device and the adhesive layer after hardening was viewed from above. As follows, the conformity of the unevenness of the gas barrier laminate was evaluated based on the existence of a gap between the pseudo-device and the adhesive layer. A: There is no gap between the pseudo device and the adhesive layer, so the unevenness followability is good. F: A gap was confirmed between the pseudo-device and the adhesive layer, so the unevenness followability was poor. [0095] [0096] Since the adhesive layer of the gas barrier laminates produced in Examples 1 and 2 has excellent interlayer adhesion with the gas barrier layer and low water vapor transmission rate, it can be said that the moisture passing through the adhesive layer is suppressed. A sealing material excellent in immersion into a sealed body. On the other hand, the gas barrier layered laminate produced in Comparative Example 1 resulted from poor adhesion between the adhesive layer and the gas barrier layer. In addition, the water vapor transmission rate of the adhesive layer included in the gas barrier layered product produced in Comparative Example 2 was a very high value. Therefore, in Comparative Example 2, it ended without performing another test.
