Description
本發明為關於有機EL元件之密封用陽離子聚合硬化型噴墨用樹脂組成物。This invention relates to the resin composition for cationic polymerization hardening type inkjet for sealing of an organic EL element.
近年,由於有機電致發光元件(以下亦稱為「有機EL元件」)的高輝度、低消耗電力,故被使用於次世代的照明或顯示器等的電子裝置中。若該有機EL元件與水或氧接觸時,會產生劣化、輝度降低、或是變得不發光之問題。因此,必須保護有機EL元件以免於入侵至電子裝置中的水或氧。為此採用了使用金屬板或玻璃板而成的密封構造,但該構造時則無法使裝置可撓性化。In recent years, organic electroluminescence elements (hereinafter also referred to as "organic EL elements") have been used in electronic devices such as next-generation lighting and displays due to their high brightness and low power consumption. When the organic EL element is brought into contact with water or oxygen, problems such as deterioration, decrease in luminance, or non-light emission occur. Therefore, the organic EL element must be protected from water or oxygen intruding into the electronic device. For this purpose, a sealing structure using a metal plate or a glass plate is used, but in this structure, the device cannot be made flexible.
作為能使裝置可撓性化之同時並能保護有機EL元件以免於水或氧之方法,有將複數的無機層及有機層交互地進行層合於有機EL元件上來形成阻障膜(barrier film),以密封有機EL元件之方法。依據該方法,藉由阻障膜而延長了水及氧的穿透路徑,將可保護有機EL元件以免於入侵至電子裝置中的水或氧。作為該阻障膜的無機層之形成方法係以ALD、CVD及濺鍍來進行。作為有機層之形成方法,如專利文獻1係揭示著藉由蒸鍍之方法。然而,藉由蒸鍍來形成有機層之方法時,所使用的組成物的損失(loss)為多之同時,亦具有反應室(chamber)會被污染之類的問題。As a method capable of making the device flexible and protecting the organic EL element from water or oxygen, there is a method in which a plurality of inorganic layers and organic layers are alternately laminated on the organic EL element to form a barrier film. ) To seal the organic EL element. According to this method, the penetration path of water and oxygen is extended by the barrier film, and the organic EL element can be protected from water or oxygen invading into the electronic device. The method for forming the inorganic layer as the barrier film is performed by ALD, CVD, and sputtering. As a method for forming the organic layer, Patent Document 1 discloses a method by vapor deposition. However, in the method for forming an organic layer by vapor deposition, there are many problems such as the loss of the composition used and the contamination of the chamber.
另一方面,作為塗佈組成物以形成有機層之一般的方法,如有噴墨法。藉由噴墨法係可解決蒸鍍法的上述問題點,但為了使從噴墨的噴嘴進行吐出,必須讓組成物成為低黏度。On the other hand, as a general method of applying a composition to form an organic layer, there is an inkjet method. The inkjet method can solve the above-mentioned problems of the vapor deposition method. However, in order to discharge the inkjet nozzle, the composition must have a low viscosity.
專利文獻2中揭示著一種作為噴墨塗佈用的組成物,其係使用於有機EL元件密封用阻障膜的有機層,藉由使用包含特定的聚矽氧化合物而成的硬化性樹脂,使組成物成為低黏度化。 [先前技術文獻] [專利文獻]Patent Document 2 discloses a composition for inkjet coating, which is used as an organic layer of a barrier film for sealing an organic EL element, and uses a curable resin containing a specific polysiloxane, Make the composition low in viscosity. [Prior Art Literature] [Patent Literature]
[專利文獻1] 日本特表2005-522891號公報 [專利文獻2] WO2016/167347號公報[Patent Document 1] Japanese Patent Publication No. 2005-522891 [Patent Document 2] WO2016 / 167347
[發明所欲解決之課題][Problems to be Solved by the Invention]
專利文獻2中所揭示的噴墨塗佈用的組成物,作為硬化性樹脂,除了特定的聚矽氧化合物以外亦包含黏度較高的樹脂,故組成物整體而言黏度仍為高,而難以在室溫下使用於噴墨。又,專利文獻2的噴墨塗佈用的組成物係以365nm的所謂的短波長來確認其硬化性,而被要求著即使是在可見光域亦可硬化的更優異的硬化性。 因此,本發明之課題係提供一種低黏度、且硬化性為優異、不具有著色的問題的有機EL元件之密封用樹脂組成物。 [解決課題之手段]The composition for inkjet coating disclosed in Patent Document 2 contains a resin having a high viscosity as a curable resin in addition to a specific polysiloxane, and therefore the composition has a high viscosity as a whole, which is difficult. Used for inkjet at room temperature. In addition, the composition for inkjet coating of Patent Document 2 confirms its curability at a so-called short wavelength of 365 nm, and is required to have more excellent curability even in the visible light region. Therefore, an object of the present invention is to provide a resin composition for sealing an organic EL device having a low viscosity, an excellent curability, and no coloring problem.

<測定方法及評估基準> (黏度) 使用黏度計(東機產業製RC-215),以25℃、No.1°34’×R24轉子、100rpm之條件下來進行測定。<Measurement method and evaluation criteria> (Viscosity) Measured at 25 ° C, No. 1 ° 34 '× R24 rotor, and 100 rpm using a viscometer (RC-215 manufactured by Toki Sangyo).
(薄膜硬化性) 將實施例及比較例之各樹脂組成物,利用旋轉塗佈法以10μm的厚度來塗佈至玻璃基板上,對於塗膜分別進行: (1)以100mW/cm2 、10秒鐘(1000mJ/cm2 )來照射395nm的LED之情形; (2)以100mW/cm2 、30秒鐘(3000mJ/cm2 )來照射395nm的LED之情形; (3)使通過金屬鹵素燈(MHL)2次以照射3000mJ/cm2 之情形; ,利用手指觸碰並依據以下之基準來評估光照射後立即的硬化狀態。 ○:膜的表面為乾燥,故判斷硬化為充分結束。 △:在膜上殘留部分的沾黏性,故判斷隨著時間的繼續經過而硬化會持續進行,但於上述照射後當下的硬化為不足。 ×:膜整體性並未乾燥,故判斷硬化性為不足。(Film hardenability) Each resin composition of the examples and comparative examples was applied on a glass substrate by a spin coating method to a thickness of 10 μm, and the coating films were each performed: (1) at 100 mW / cm 2 , 10 seconds (1000mJ / cm 2) to illuminate an LED 395nm case; (2) at 100mW / cm 2, 30 seconds (3000mJ / cm 2) to illuminate an LED 395nm situation; (3) passing through the metal halide lamp (the MHL) is irradiated 2 times to 3000mJ / cm 2 of the case; by finger touch and evaluated according to the following basis of a hardened state immediately after the light irradiation. :: The surface of the film is dry, so it is judged that the curing is sufficiently completed. (Triangle | delta): The stickiness of the residual part on a film, it is judged that hardening will continue as time progresses, but the current hardening after the said irradiation is insufficient. ×: The integrity of the film was not dried, so the hardenability was judged to be insufficient.
(著色) 使實施例及比較例之各樹脂組成物成為厚度100μm之方式利用載玻片來予以夾住,以100mW/cm2 、10秒鐘(1000mJ/cm2 )來照射395nm的LED,利用目視對於光照射後立即的著色狀態來進行外觀觀察,並依以下之基準來進行評估。 ○:幾乎為無色 ×:帶有黃色(Coloring) Each resin composition of the Examples and Comparative Examples was sandwiched by a glass slide so that the thickness was 100 μm, and 395 nm LEDs were irradiated at 100 mW / cm 2 for 10 seconds (1000 mJ / cm 2 ), The appearance of the coloring state immediately after light irradiation was visually observed, and evaluated based on the following criteria. ○: almost colorless ×: with yellow
[實施例1~8、比較例1~5] 依據表1所記載之調配,將各成分放入容量160m1的NANKO容器中,在室溫(25℃)下利用Three-one-motor(新東科學公司製)來進行攪拌,而得到約50g的樹脂組成物。 [Examples 1 to 8, Comparative Examples 1 to 5] According to the preparations described in Table 1, each component was placed in a NANKO container with a capacity of 160 m1, and a three-one-motor (Shinto) was used at room temperature (25 ° C). (Manufactured by Scientific Corporation), and about 50 g of a resin composition was obtained.
將實施例1~3與比較例1及2進行比較時可得知,若使用其他的氧雜環丁烷化合物的AL-OX來替代上述式(II)所表示之化合物的話,硬化性為差。將實施例1~3與比較例3進行比較時可得知,若大量地使用縮水甘油基化合物的EX-141來替代上述式(II)所表示之化合物的話,硬化性為差。由實施例4~8可得知,上述式(II)所表示之化合物即使是不與上述式(I)之化合物組合,亦可展現出良好的硬化性、且無著色。將實施例與比較例4及5進行比較時可得知,作為光聚合起始劑,若使用鋶鹽的CPI-410S來替代碘鎓鹽的話,量較少之情形時則硬化性為差,而量較多之情形時雖然硬化性為些許不佳之程度,但產生了著色的問題。 [產業利用性]When comparing Examples 1 to 3 and Comparative Examples 1 and 2, it can be seen that if AL-OX of another oxetane compound is used instead of the compound represented by the formula (II), the hardenability is poor. . When comparing Examples 1 to 3 and Comparative Example 3, it was found that if a large amount of EX-141 of a glycidyl compound is used instead of the compound represented by the formula (II), the hardenability is poor. It can be seen from Examples 4 to 8 that the compound represented by the above formula (II) can exhibit good hardenability without coloring even if it is not combined with the compound of the above formula (I). When comparing the Examples with Comparative Examples 4 and 5, it can be seen that, as a photopolymerization initiator, if CPI-410S of a sulfonium salt is used instead of the iodonium salt, the curability is poor when the amount is small. On the other hand, when the amount is large, although the hardenability is somewhat poor, coloring problems occur. [Industrial availability]
