Description

[Technical Field] The present invention relates to a composition, a hardened body for moisture capture formed from the composition, and an electronic device including the cured body. [Prior Art] An electronic device that has suffered a malfunction due to moisture, such as a capacitor or an organic EL element, must be used in a sealed state for removing moisture. However, the use of only an encapsulant for such a sealed electronic device does not completely prevent the intrusion of moisture. Therefore, if there is no structure for slowly removing moisture in the device, the function of the electronic device will slowly decrease over time. For example, the organic EL element of a typical sealed electronic device has a problem that the light-emitting characteristics such as brightness or luminous efficiency are gradually lowered due to the intrusion into the organic EL element due to the long-term driving time. As for the means for protecting the sealed electronic device from the outside, the organic metal is disposed in the device, for example, as disclosed in Japanese Laid-Open Patent Publication No. Hei. No. Hei. A moisture trapping agent such as a compound or a metal alkoxide is a technique for keeping the inside of the apparatus in a low humidity environment. [Problem to be Solved by the Invention] However, when such an organometallic compound or a metal alkoxide is used as a water scavenger, the product is decomposed by reacting with water to form a hospital or an alcohol. When such a decomposition product diffuses into the interior of the apparatus, it is absorbed in an organic material such as a charge transporting layer or an organic light-emitting layer constituting the device, and there is a possibility that the void volume expansion in the device is caused. As a result, pinholes are formed in the apparatus, and the apparatus is deformed to promote moisture intrusion, which shortens the life of the apparatus. Further, it is usually necessary to dissolve the water-trapping agent in a solvent to prepare a coating liquid, and to form the coating liquid by a coating method such as spin coating, and to form it by removing the solvent. However, when formed by this method, a solvent remains in the film. In this case, as in the above decomposition products, the solvent remaining in the film diffuses into the interior of the device and is absorbed in the organic material such as the charge transport layer or the organic light-emitting layer constituting the device, and causes the void volume existing in the device. The swell of expansion. As a result, there is a possibility that a pinhole is formed in the apparatus, and the apparatus is deformed to promote the intrusion of moisture, and the life of the apparatus is shortened. Therefore, it is desirable to develop a moisture trapping agent that removes a solvent as much as possible. In addition, such a water-trapping agent may be deformed by heat flow in a use environment (for example, about 80 °C in organic EL illumination), and may not be transparent due to reaction with water. On the other hand, since the moisture trapping agent is usually formed on a surface such as a glass substrate, it is required to have excellent film formability and excellent glass adhesion. Therefore, the present invention can solve the above-mentioned problems, and it is excellent in water absorbing property and thermal fluidity (heat resistance), and can form a hardened body excellent in transparency, film formability, and glass adhesion. A composition for moisture capture, a cured body formed of the composition, and an electronic device including the cured body. -6- 201221507 [Means for Solving the Problems] The present invention has been made to solve at least a part of the above problems, and can be realized by the following aspects or application examples.

[Application Example 7] -8-201221507 The electronic device of the present invention is characterized in that it has a hardened body for moisture capture as in Application Example 6. [Effects of the Invention] According to the composition of the present invention, a cured body (coating film, film, or the like) which is excellent in hygroscopicity and heat resistance and excellent in transparency, film formability, and glass adhesion can be formed. The hardened body is not deformed by thermal fluidity even in a use environment of, for example, more than 80 °C. Further, the composition of the present invention can be in a solvent-free state. According to this aspect, no solvent remains in the hardened body. Therefore, since the hardened body is mounted in the electronic device, the electronic device is not damaged by the residual solvent in the hardened body, and for example, the occurrence of pinholes or moisture intrusion due to deformation of the device can be prevented. The above-mentioned hardened body for water-trapping can be preferably used as a water-trapping agent in an electronic device such as an organic EL device, and can be used, for example, in a top emission organic EL device when it is excellent in transparency. .

(Α) Component The composition of the present embodiment contains the compound (Α) represented by the above formula (1). One of the functions of the (Α) component is exemplified by capturing moisture by reacting the RLM bond present in the (Α) component with moisture. By using the component (A), a hardened body excellent in hygroscopicity can be obtained. That is, in order to use the hardened body formed of the composition of the present embodiment for capturing moisture, a bond must be substantially present in the hardened body.

In the above formula (1), R1 is a self-substituted or unsubstituted alkyl group; 10-201221507, alkenyl group, alkynyl group, cycloalkyl group, aryl group, carboxyl group, (meth) group and r2- o is a selected one of the groups, and the plurality of existences may be the same or different, but at least one of the plurality of existing R1 is a group of more than one unsaturated bond. R1 is preferably a group represented by R2-0-, which is selected from the group consisting of a substituted or unsubstituted alkyl group, an alkenyl group, an alkynyl group, and a cyclic group. R1 and R2 may be linear or cyclic, and have a branched chain. Further, when R1 and R2 are an alkenyl group or an alkynyl group, the position and number of each triple bond are not particularly limited. Further, R 1 can be appropriately selected from the above-exemplified groups in consideration of the properties of the cured body. In the case of any of the examples, it is possible to improve the compatibility between the component (A) and the latter (B). As a result, the phase separation can be suppressed even if it is left standing, and a composition having good stability can be stored. In the above, since η is 2 or 3, R1 is complexed. Among them, a plurality of existing R1 may be the same or different, but at least one of the plurality of R1 has more than one unsaturated bond. There is no particular limitation. Since R1 has a bond and a bond, it can facilitate the radical polymerization of the (Α) component, whereby the (Α) component is copolymerized with the (Β) component and immobilized.

Further, the boiling point of the hydrolyzed component is 200 ° C or higher, more preferably 25 ° C or higher. If it is at 200 ° C or higher, the diffusion of the hydrolysis component into the electronic device is suppressed. Further, when R1 is a group having two or more unsaturated bonds, the crosslinking structure of the reaction product of the water and the component (B) is preferable.

Further, -23-201221507, when the inorganic particles are used as the heat-transfering agent, not only the thermal conductivity of the cured body formed using the composition of the present embodiment but also the component which is decomposed by the moisture absorption of the component (A) can be adsorbed. (decomposition product), the decomposition product is captured inside the hardened body. According to this, the plasticizer which prevents the aforementioned decomposition product from becoming a hardened body functions. That is, the cured body formed using the composition of the present embodiment is not deformed by the flow of heat even in an environment of use exceeding 80 °C, for example.

Production of a film", hygroscopicity, transparency, film formability, glass adhesion, and storage stability were evaluated by the following methods. (gelation time). Further, the thermal fluidity was measured and evaluated by the following method. The results are shown together in Tables 1 to 3. (1) In a glassware having a hygroscopic inner diameter of 3 cm, each of the films of the examples and the comparative examples having a thickness of 0.6 mm was placed in each glassware in a desiccator equipped with a hygrometer and a thermometer having an internal volume of 800 cm3. The previously produced film was used to determine the change in humidity and temperature inside the dryer. From the measured relative humidity (Hr, %) and Celsius temperature (Tc, °C), the absolute humidity (Ha, %) was determined by the following formula (7). Next, the water absorption ratio was calculated from the absolute humidity Ha ( Oh ) at the start of the measurement to the absolute humidity Ha ( 2h ) after 2 hours as the water absorption rate, and the water absorption rate was calculated and evaluated by the following formula (8).

Ha = 4.0xl0'3{exp(6.4xl0'2 · Tc)}Hr (7) Water absorption (%) = 100x(Ha(0h)-Ha(2h))/Ha(0h) ... (8 The water absorption rate (%) is preferably 20% or more, more preferably 30% or more, and most preferably 40% or more. (2) Thermal fluidity (heat resistance)

S -38- 201221507 First, an appropriate amount of each of the components A to Z, AA to AB is placed in a sample tube, and heated at 80 ° C for 10 minutes to 1 hour, thereby producing a film thickness of 2 mm at the bottom of the sample tube. The film. Next, after the film was sufficiently absorbed in the atmosphere, the lid was sealed and sealed, and the sample tube was placed in an environment of 85 ° C in a state where the bottom of the sample tube was fixed upward (the film formation surface was upward). The state of the film after 316 hours was observed. Further, the evaluation criteria of the thermal fluidity were referred to as "〇" in the case where no change in the film was observed, and "X" was observed in the case where the film was sagged downward. (3) Transparency The film obtained in the above-mentioned "4.5.1. Production of a film" was visually observed as "〇j," and "X" was produced in the case where white opacity was observed. Further, when it is applied to a surface emitting organic EL or the like which requires transparency, it is preferably a transparency. (4) Film-forming property For the film obtained in the above-mentioned "4.5.1. Film production", the film was observed to be free from cracks and irregularities, and it was marked as "〇", and it was found that there was crack or unevenness on the film. Recorded as "X". Further, when it is applied to applications such as organic EL, it is preferred that the occurrence of cracks and irregularities is suppressed. (5) Glass adhesion The film obtained in the above-mentioned "4.5.1. Film production" is not marked as "〇" in the air, and is marked as "X" in the peeling. -39- 201221507 Further, when it is applied to a display material which requires adhesion to a glass substrate, it is preferred that the glass adhesion is good. (6) Storage stability After the composition was prepared, the obtained composition was immediately added in a small amount in a transparent glass container and sealed. The time elapsed from the time when the composition was added to the glass container until the fluidity was not observed in the composition was evaluated as the gelation time. The confirmation of the fluidity was carried out by tilting the glass container to visually observe the state of the composition at this time. 4.5.3. Evaluation results According to the results of Table 1, according to the films formed from the compositions of Examples 1 to 23, it was found that since any of the compositions contained the components (A) and (C), it was formed by A) The polymer of the component has excellent hygroscopicity and heat resistance. Further, according to the compositions of Examples 1 to 23, it was found that a film excellent in transparency, film formability, and glass adhesion was obtained. Further, it was found that Examples 7 to 9 and Examples 20 to 22 in which the stabilizer was added were not gelled for 1 week or longer. On the other hand, since the film formed from the composition of Comparative Example 1 and Comparative Example 4 did not contain the component (C), the solution could not be in the form of a film. Therefore, evaluation tests other than storage stability cannot be performed. The film "formed by the composition of Comparative Example 2 and Comparative Example 3" was replaced with TDDOA or CaO having no polymerizable functional group instead of (A) component. Thus, only TMPT was subjected to polymerization reaction to form a film of white turbidity. Further, the film formed of the composition of Comparative Example 3 was not dissolved in the component (B) because CaO was not dissolved.

S -40- 201221507, therefore, it becomes a very brittle film with high viscosity, and filming property and glass adhesion also cause problems. Since the film formed from the composition of Comparative Example 5 was not dissolved in the component (B), CaO was a very brittle film having a high viscosity, and there was a problem in film formability and glass adhesion. From the above results, it is understood that the film formed from the composition containing the component (A) and the component (C) is excellent in water absorption and heat resistance, and also excellent in transparency, film formability, and glass adhesion.
