Problems solved by technology

However, according to the research of the present inventors, it has been found that if aluminum alkoxide is used as a representative water-catching component in these compositions, there may be problems in storage stability as follows: the reactivity (activity) of aluminum alkoxide High cause, due to a small amount of moisture, the composition will undergo deterioration such as aggregation, cloudiness, etc.; the usable time is short; and the curing reaction of the composition (polymerization reaction of the polymerizable monomer) will increase during storage, and the viscosity will increase, making it impossible to coat the composition. Things etc.

Embodiment

[0080] Hereinafter, the present invention will be described more specifically with reference to examples. However, the present invention is not limited to these Examples.

[0081] [Synthesis of Compound (Water Capture Component)] (Example 1)

[0082] Put trimethylolpropane diallyl ether (2,2-bis(allyloxymethyl)-1-butanol, a compound represented by formula (3-1)) into the flask (trade name: new Allyl T-20, 21 parts by mass of OSAKA SODA CO., LTD.) and 10 parts by mass of tetrapropoxy zirconium (Tokyo Chemical Industry Co., Ltd.) were stirred at 25° C. for 1 hour. Then, the volatile components were distilled off under reduced pressure at 60° C. and 300 Pa for 3 hours, and the volatile components were further distilled under reduced pressure at 150° C. and 300 Pa for 3 hours to obtain the compound of Example 1 as a transparent viscous body. Since 4 equivalents of trimethylolpropane diallyl ether were reacted with tetrapropoxyzirconium, it is speculated that the compound of Exam...

Abstract

Disclosed is a compound represented by general formula (1). In formula (1), M represents a titanium atom, a zirconium atom or a hafnium atom; R1, R2, R3 and R4 each represents an alkyl group which may be substituted by a group containing a polymerizable unsaturated bond. However, at least one of R1, R2, R3, and R4 is an alkyl group substituted with a group containing a polymerizable unsaturated bond.

Description

technical field [0001] The present invention relates to a compound, a photocurable composition, a cured film, and an organic EL element. Background technique [0002] A film sealing technique is known as a technique for sealing a light emitting portion of a top emission type organic EL element. The film sealing technique is a technique of sealing the light emitting part by alternately forming inorganic films and organic films. The thus obtained alternately laminated sealing film can prevent the intrusion of moisture and the like into the light-emitting portion. [0003] As a material for forming an organic film, for example, a composition containing a combination of a polyethylene glycol di(meth)acrylate monomer and pentaerythritol tetra(meth)acrylate is disclosed (see Patent Document 1). [0004] Patent Document 1: Japanese PCT Publication No. 2017-531049 [0005] In the composition described in Patent Document 1, since the polymerizable monomer having a hydrophilic func...
