[0019] According to the present invention, it is possible to provide a composition that is excellent in curability, adhesiveness, and / or durability of the cured product. Furthermore, the present invention can provide a compound that is highly curable and suitable for obtaining the composition.

[0020] The compound, composition, polymer and cured product of the present invention will be described below.

[0021] A. Compound First, the compound of the present invention (hereinafter, sometimes referred to as "Compound A") will be described. The compound of the present disclosure is a compound having a structure represented by the following general formula (I), a structure represented by the following general formula (II), and an unsaturated bond-containing group, and is a compound having two or more structures represented by the following general formula (I).

[0022] In the general formula, R represents a hydrogen atom, a halogen atom, a cyano group, an amino group, a hydroxyl group, a nitro group, a carboxyl group, a hydrocarbon group having 1 to 30 carbon atoms in which a hydrogen atom may be substituted with a substituent, or a hydrocarbon group having 1 to 30 carbon atoms in which one or more methylene groups are substituted with a group selected from <Group A> below, and in which a hydrogen atom may be substituted with a substituent. Hereinafter, "a hydrocarbon group in which one or more methylene groups are substituted with a group selected from <Group A> below" will also be referred to as "methylene-substituted hydrocarbon group".

[0023] a is an integer of 0 to 5, b is an integer of 0 to 5, a+b is an integer of 1 or more, *, ** and *** are bonding points,

[0024] D and J each independently represent a direct bond, a hydrocarbon group having 1 to 30 carbon atoms in which a hydrogen atom may be substituted by a substituent, or a methylene-substituted hydrocarbon group having 1 to 30 carbon atoms in which a hydrogen atom may be substituted by a substituent; G and L each independently represent a direct bond or a group selected from the following <Group A>, <Group A> being -O-, -S-, -NR １０１-, -CO-, -CO-O-, -O-CO-, CO-NR １０１ -, -NR １０１ -CO-, -CO-S- or -S-CO-, R １０１ is a hydrogen atom, a halogen atom, a cyano group, an amino group, a hydroxyl group, a nitro group, a carboxyl group, a hydrocarbon group having 1 to 10 carbon atoms, or a heterocyclic group having 2 to 10 carbon atoms. When there are multiple R, D, G, J, and L in one molecule, they may be the same or different. Here, "same" includes symmetrical relationships. An example of mutual symmetry is the relationship between -COO- and -OCO-.

[0025] Compound A of the present disclosure is highly curable due to its structure, and can achieve high curability in compositions such as curable resin compositions. Furthermore, when compound A is used in compositions such as curable resin compositions, it can also achieve high adhesion upon curing. Furthermore, compound A and compositions using the same can achieve low cure shrinkage because compound A also functions as a crosslinking agent, and the durability of the cured product is also excellent. Hereinafter, the durability of the cured product will also be simply referred to as "durability." By achieving the effects described above, compound A of the present disclosure can be suitably used for curable adhesives and coatings.

[0026] Compound A of the present disclosure will be described in detail below. As described above, the compound of the present disclosure is a compound having a structure represented by the following general formula (I), a structure represented by the following general formula (II), and an unsaturated bond-containing group, and is a compound having two or more structures represented by the following general formula (I). Here, having the structure represented by the general formula (I) (hereinafter sometimes referred to as Structure I), the structure represented by the general formula (II) (hereinafter sometimes referred to as Structure II), and an unsaturated bond-containing group means that Structure I, Structure II, and the unsaturated bond-containing group are contained in the same molecule. Similarly, having two or more structures represented by the general formula (I) means that two or more Structures I are contained in the same molecule. Furthermore, Structure I, Structure II, and the unsaturated bond-containing group may be directly covalently bonded at *, **, and *** in Structure I and Structure II, or may be covalently bonded via a linking group.

[0027] The combination of bonds between the Structure I, the Structure II, and the unsaturated bond-containing group may include any combination of a bond between Structure I and Structure II, a bond between Structure I and the unsaturated bond-containing group, a bond between Structure II and the unsaturated bond-containing group, a bond between Structures I, a bond between Structures II, and a bond between unsaturated bond-containing groups. The compound of the present disclosure contains at least two Structures I, at least one Structure II, and at least one unsaturated bond-containing group, which are covalently bonded directly or via a linking group in any of the above combinations. Preferably, the compound includes a bond between Structure I and Structure II and / or a bond between Structure II and the unsaturated bond-containing group.

[0028] The unsaturated bond-containing group is an unsaturated bond group, that is, a group containing a carbon-carbon double bond. A carbon-carbon double bond is sometimes called an aliphatic double bond. Specific examples of the unsaturated bond-containing group include groups in which a carbon-carbon single bond in a hydrocarbon group and a total of two hydrogen atoms bonded to the carbon atom are substituted with a carbon-carbon double bond. The unsaturated bond-containing group may have multiple carbon-carbon double bonds, but the double bonds are not adjacent to each other, for example, as in -C=C=C-. As the hydrocarbon group substituted with a carbon-carbon double bond, a divalent group in which one hydrogen atom has been removed can be used from among the monovalent groups listed as hydrocarbon groups used for R in the structure I described below.

[0029] Examples of divalent groups obtained by removing one hydrogen atom from a monovalent hydrocarbon group include alkylene groups, which are groups obtained by removing one hydrogen atom from an alkyl group. Examples of alkylene groups include linear and branched groups such as methylene, 1,2-ethylene, 1,2-propylene, 1,3-propylene, 1,4-butylene, 1,6-hexylene, 2-methyltrimethylene, 2-methyltetramethylene, and 2-methylpentamethylene.

[0030] When a divalent group obtained by removing one hydrogen atom from an aryl group or an arylalkyl group is used as the unsaturated bond-containing group, it is necessary that the group have an aliphatic carbon-carbon double bond in addition to the aromatic carbon-carbon double bond constituting the aromatic ring. Furthermore, when a group obtained by replacing the carbon-carbon single bond in a divalent group obtained by removing one hydrogen atom from a cycloalkyl group or a cycloalkylalkyl group with a carbon-carbon double bond is used as the unsaturated bond-containing group, the unsaturated bond-containing group does not include groups having only aromatic carbon-carbon double bonds constituting the aromatic ring.

[0031] In the present disclosure, the number of carbon atoms in the unsaturated bond-containing group is preferably 2 to 15, more preferably 2 to 10, particularly preferably 2 to 5, particularly preferably 2 or 3, and most preferably 2. Having the above structure, Compound A and compositions using the same have higher curability, and the durability and adhesiveness of the cured product can be improved.

[0032] Furthermore, the monovalent hydrocarbon group substituted with a carbon-carbon double bond before removing one hydrogen atom is preferably an alkyl group, a cycloalkyl group, a cycloalkylalkyl group, an aryl group, or an arylalkyl group, and among these, an alkyl group, a cycloalkyl group, or a cycloalkylalkyl group is preferred, with an alkyl group being particularly preferred. Having this structure makes compound A and compositions using it more highly curable, and can also improve the durability and adhesiveness of the cured product.

[0033] The hydrocarbon group substituted with a carbon-carbon double bond may have one or more hydrogen atoms in the group substituted with a substituent, or one or more methylene groups in the group substituted with a group selected from Group A above, but is preferably unsubstituted or one or more methylene groups in the group substituted with -O-, -CO-, -CO-O-, or -O-CO-, and is preferably unsubstituted. Having the above structure, Compound A and compositions using it have higher curability and can improve the durability and adhesion of the cured product.

[0034] The bonding mode of formula (I) and / or formula (II) to the carbon-carbon double bond in the unsaturated bond-containing group may be either a cis or trans isomer, but the trans isomer is preferred because it has higher reactivity. The bonding of formula (I) and / or formula (II) to the carbon-carbon double bond is direct or via a linking group.

[0035] In the above-mentioned Structure I, Structure II, and unsaturated bond-containing group (hereinafter also referred to as "Structure I, etc."), one or more hydrogen atoms in the structure may be substituted with a substituent. Examples of the substituent substituting the hydrogen atom include a halogen atom, a cyano group, a nitro group, a hydroxyl group, a thiol group, -COOH, and -SO. ３ Examples of the substituent include H, an isocyanate group, a hydrocarbon group having 1 to 10 carbon atoms, a hydrocarbon group having 1 to 10 carbon atoms in which one or more methylene groups have been substituted with a group selected from the above <Group A>, a heterocycle-containing group having 2 to 10 carbon atoms, and a heterocycle-containing group having 2 to 10 carbon atoms in which one or more methylene groups have been substituted with a group selected from the above <Group A>, and combinations thereof. Examples of the combinations include a hydrocarbon group having 1 to 10 carbon atoms or a methylene-substituted hydrocarbon group, or a heterocycle-containing group having 2 to 10 carbon atoms I or II (described below) as a substituent, which further contains a halogen atom, a cyano group, a nitro group, a hydroxyl group, a thiol group, -COOH, -SO ３ Examples include the case where a hydrogen atom in the group is substituted with an H or isocyanate group.

[0036] As mentioned above, in this specification, "a group in which one or more methylene groups in a hydrocarbon group are substituted with a group selected from the above <Group A>" is also referred to as a "methylene-substituted hydrocarbon group." Furthermore, the heterocyclic group I described below, heterocyclic group II in which one or more hydrogen atoms of heterocyclic group I are substituted with hydrocarbon groups, and groups in which hydrogen atoms in these groups are substituted with substituents are referred to as heterocycle-containing groups I, and "a group in which a methylene group in a hydrocarbon group in heterocycle-containing group I is substituted with a group selected from the above <Group A>" is also referred to as a "heterocycle-containing group II." Unless otherwise specified, the term "heterocycle-containing group" can refer to both heterocycle-containing groups I and II.

[0037] In the present disclosure, the number of carbon atoms in a group defines the number of carbon atoms in the group after substitution of a hydrogen atom in the group with a substituent. For example, "1 to 30 carbon atoms" in "a hydrocarbon group having a substituent of 1 to 30 carbon atoms" refers to the number of carbon atoms in the entire group after the hydrogen atoms have been substituted, and does not refer to the number of carbon atoms in the hydrocarbon group before the hydrogen atoms are substituted. In addition, in the present disclosure, the number of carbon atoms in a group in which a methylene group in a group with a predetermined number of carbon atoms has been substituted with a group selected from the above <Group A> defines the number of carbon atoms in the group after substitution. For example, in this specification, examples of hydrocarbon groups in a predetermined (e.g., 1 to 30 carbon atoms) methylene-substituted hydrocarbon group are the same as the examples of a predetermined (e.g., 1 to 30 carbon atoms) hydrocarbon group, but a methylene group (-CH ２ The number of carbon atoms in a group in which one of the methylene groups in a hydrocarbon group is substituted with a divalent group "-O-" is 19. Furthermore, a group in which one or more methylene groups in a hydrocarbon group are substituted with a divalent group selected from <Group A> does not have a structure in which multiple divalent groups are adjacent to each other. Nor does it have a structure in which all hydrocarbon groups are substituted with divalent groups selected from <Group A>. For example, -CO- is not a group in which a hydrocarbon group having one carbon atom (methylene group) is substituted with a group selected from <Group A>, but is the group selected from <Group A> itself. The multiple groups selected from <Group A> may be the same or different.

[0038] As the hydrocarbon group having 1 to 10 carbon atoms used as a substituent that may substitute a hydrogen atom in the structure I etc., any monovalent group having a predetermined number of carbon atoms can be used among the hydrocarbon groups used for R in the structure I described below.

[0039] The heterocyclic ring-containing group I having 2 to 10 carbon atoms, which is used as a substituent that may replace a hydrogen atom in the structure I or the like, may have 2 to 10 carbon atoms, and may include a group in which one hydrogen atom has been removed from an unsubstituted heterocyclic compound (hereinafter, a "group in which one hydrogen atom has been removed from an unsubstituted heterocyclic compound" may be referred to as a "heterocyclic group I"); a group in which one or more hydrogen atoms in the heterocyclic group I have been substituted with a hydrocarbon group (hereinafter, this may be referred to as a "heterocyclic group II"); or a group having a structure in which one or more hydrogen atoms in the unsubstituted heterocyclic group I or heterocyclic group II have been substituted with a substituent. The heterocyclic ring-containing group II is as described above. Examples of the substituent that may replace a hydrogen atom in the unsubstituted heterocyclic group I or heterocyclic group II include a halogen atom, a cyano group, a nitro group, a hydroxyl group, a thiol group, -COOH, -SO ３ H and an isocyanate group. As the hydrocarbon group used as a substituent that may substitute a hydrogen atom in the heterocyclic group I, a hydrocarbon group selected from the monovalent groups listed as the hydrocarbon group used as R in structure I described below, so as to satisfy the predetermined number of carbon atoms as a heterocycle-containing group, can be used. When a hydrogen atom in the heterocyclic group II is substituted with a substituent, the substituent may be bonded to either the heterocyclic group I or the hydrocarbon group.

[0040] The heterocyclic compound (hereinafter sometimes referred to as a heterocycle) may have a monocyclic structure or a fused ring structure. The heterocycle having a fused ring structure is a structure in which a heterocycle and a heterocycle or a hydrocarbon ring are fused together, and examples thereof include a heterocycle-containing fused ring. Specific examples of the heterocycle include saturated or unsaturated monocyclic heterocycles such as a thiophene ring, a furan ring, a pyrrole ring, a pyrrolidine ring, a pyridine ring, a piperidine ring, a piperazine ring, a morpholine ring, a thiomorpholine ring, a homopiperidine ring, a homopiperazine ring, a tetrahydropyridine ring, a tetrahydrofuran ring, a tetrahydropyran ring, a caprolactam ring, an isocyanuric ring, and a hydantoin ring; and saturated or unsaturated polycyclic hydrocarbon rings such as a tetrahydroquinoline ring, a tetrahydroisoquinoline ring, a dihydrobenzofuran ring, a tetrahydrocarbazole ring, a benzothiazole ring, a benzoxazole ring, a benzimidazole ring, an indole ring, and an indene ring.

Examples of the group substituting the hydrogen atom in the hydrocarbon group and heterocycle-containing group include a halogen atom, a cyano group, a nitro group, a hydroxyl group, a thiol group, -COOH, -SO ３ H, an isocyanate group, or an alkyl group having 1 to 6 carbon atoms. As the alkyl group having 1 to 6 carbon atoms, any monovalent group having a predetermined number of carbon atoms can be used, among the alkyl groups used for R in Structure I described below.

[0042] As the hydrocarbon group having 1 to 20 carbon atoms used in the linking group, a divalent or higher valent group obtained by removing one or more hydrogen atoms from a monovalent group exemplified as the hydrocarbon group used for R in Structure I described below can be used.

[0043] As the heterocycle-containing group having 2 to 20 carbon atoms used in the linking group, a divalent or higher group in which one or more hydrogen atoms have been removed from the groups exemplified as heterocycle-containing groups used as substituents that may substitute hydrogen atoms in the structure I or the like, or groups similar thereto, can be used.

[0178] [Evaluation 1] 1. Preparation of Composition 3 g of Compound A1, 4 g of GPE, 1 g of EP-4100E, and 2 g of Viscoat #540 were added and stirred until uniform. After stirring, 0.3 g of SP-151 as a photocationic polymerization initiator and 0.3 g of Irg819 as a photoradical polymerization initiator were added and stirred until uniform, thereby obtaining a composition (Example 1). Each composition was prepared using the blending amounts shown in Tables 2, 3, and 4, and the compositions of Examples 2 to 5 and Comparative Examples 1 to 12 were obtained.

[0179] 2. Evaluation of adhesive strength Approximately 0.2 mL of the composition was applied to a glass plate, sandwiched between SUS substrates, and exposed to light from the glass surface (exposure dose 3000 mJ / cm ２ ), and a sample for adhesion test was prepared. The shear stress of the sample was measured using a universal testing machine (Shimadzu Corporation). The peeled area after peeling was also measured using a micrometer.
