[0149] According to one aspect of the invention, the composition comprises at least, substantially consists of, or consists of the following;

[0150] i) A reactive monomer, preferably having one or more functional groups, more preferably a (meth)acrylate monomer;

[0151] ii) The luminescent part; and

[0152] iii) A compound comprising at least one straight-chain or branched alkyl group having 1 to 45 carbon atoms, a straight-chain or branched alkenyl group having 1 to 45 carbon atoms, or a straight-chain or branched alkoxy group having 1 to 45 carbon atoms, preferably having 10 to 35 carbon atoms, more preferably 14 to 30, even more preferably 16 to 28, and further preferably 19 to 26, preferably having the alkyl group, alkenyl group, and / or alkoxy group substituted or unsubstituted, preferably comprising at least one straight-chain or branched alkyl group, wherein the chain contains at least one carbon-carbon double bond, preferably having 1 to 5 carbon-carbon double bonds, more preferably 1 to 3 carbon-carbon double bonds, even more preferably 1 to 2 carbon-carbon double bonds.

[0153] In another aspect, the present invention relates to a composition, preferably a photocurable composition, comprising at least the following:

[0154] L) reactive monomer, preferably having one or more functional groups, more preferably (meth)acrylate monomer;

[0155] L2) The luminescent portion contains at least one ligand, the ligand comprising at least one straight-chain or branched alkyl group having 1 to 45 carbon atoms, a straight-chain or branched alkenyl group having 1 to 45 carbon atoms, or a straight-chain or branched alkoxy group having 1 to 45 carbon atoms; and

[0156] L3) compounds comprising at least one straight-chain or branched alkyl group having 1 to 45 carbon atoms, a straight-chain or branched alkenyl group having 1 to 45 carbon atoms, or a straight-chain or branched alkoxy group having 1 to 45 carbon atoms, preferably having 10 to 35 carbon atoms in the alkyl, alkenyl, and / or alkoxy group, more preferably 14 to 30, even more preferably 16 to 28, and further preferably 19 to 26, preferably having the alkyl, alkenyl, and / or alkoxy group substituted or unsubstituted, and preferably containing at least one straight-chain or branched alkyl group.

[0157] In a preferred embodiment of the present invention, the number of carbon atoms of the alkyl, alkenyl, and alkoxy groups of the ligand satisfies the following formula (Q) relative to the number of carbon atoms of the alkyl, alkenyl, and alkoxy groups of the compound. Preferably, the chain contains at least one carbon-carbon double bond, more preferably, the chain contains 1 to 5 carbon-carbon double bonds, more preferably 1 to 3 carbon-carbon double bonds, and even more preferably 1 to 2 carbon-carbon double bonds.

[0158] The number of carbon atoms in the alkyl, alkenyl, and alkoxy groups of the ligand is less than the number of carbon atoms in the alkyl, alkenyl, and alkoxy groups of the compound. (Q)

[0159] Preferably, the number of carbon atoms in the alkyl, alkenyl, and alkoxy groups of the compound is 1 to 20 greater than the number of carbon atoms in the alkyl, alkenyl, and alkoxy groups of the ligand, more preferably 3 to 15 greater, even more preferably 5 to 12 greater, and even more preferably the group contains at least one carbon-carbon double bond. Furthermore, it is preferred that the position of the at least one carbon-carbon double bond in the compound's group is located further outward than the CH3 end of the ligand (on the -CH3 end side of the group). In other words, the length of the compound's group is longer than the length of the ligand's group, and it is preferred that the position of the at least one carbon-carbon double bond in the compound's group is located further outward (longer) than the edge of the ligand's group.

[0160] It is believed that longer compound lengths improve the dispersion of the luminescent portion and / or scattering particles. If the carbon-carbon double bond is located further out (on the longer side) of the self-ligand edge, it creates a steric effect in the compound, subsequently allowing the alkyl, alkenyl, and alkoxy groups of the compound to disperse (not aligned in the same direction). This can then lead to good compatibility / interaction with reactive monomers.

[0161] -compounds

[0162] It is believed that the compound preferably controls the viscosity / solubility of the composition accordingly. More preferably, it can prevent the viscosity of the composition from increasing and / or maintain good solubility of the luminescent portion during long-term storage in the composition.

[0163] Furthermore, it is believed that one or more carbon-carbon double bonds in the chain can result in lower viscosity in the composition and improved dispersion of the luminescent portion and / or scattering particles.

[0164] In a preferred embodiment of the invention, the compound further comprises at least one group selected from one or more members of the group consisting of: phosphin, phosphine oxide, phosphate ester, phosphonate, thiol, tertiary amine, carboxyl, heterocyclic, silyl, sulfonic acid, hydroxyl, phosphonic acid, preferably phosphate ester, phosphonate, thiol, carboxyl or any combination of these groups, more preferably carboxyl.

[0165] It is believed that phosphonate groups, thiol groups, carboxyl groups, or any combination of these groups are preferred because they have the ability to preferably adhere to the outermost surface of the inorganic portion of the luminescent part (such as the surface of the inorganic portion of a quantum material).

[0166] More preferably, the compound is composed of the following chemical formula (X A )express.

[0167] ZY - (X A )

[0168] Where Z is *-R x1 or Where “*” indicates the connection point with the symbol Y in the expression, R x1 The group is selected from one or more members of the group consisting of: phosphono, phosphonium oxide, phosphate ester, phosphonate ester, thiol, tertiary amine, carboxyl, heterocyclic, silyl, sulfonic acid, hydroxyl, phosphonic acid, preferably phosphonate ester, thiol, carboxyl, or any combination of these groups, more preferably carboxyl; and

[0169] R x2 The group is selected from one or more members of the group consisting of: phosphin, phosphine oxide, phosphate ester, phosphonate, thiol, tertiary amine, carboxyl, heterocyclic, silyl, sulfonic acid, hydroxyl, phosphonic acid, preferably phosphonate, thiol, carboxyl or any combination of these groups, more preferably carboxyl;

[0170] Y is a straight-chain or branched alkyl group having 1 to 45 carbon atoms, a straight-chain or branched alkenyl group having 1 to 45 carbon atoms, or a straight-chain or branched alkoxy group having 1 to 45 carbon atoms. Preferably, the carbon atom of the alkyl, alkenyl, and / or alkoxy group is in the range of 5 to 35, more preferably 10 to 25, even more preferably 12 to 24, and further preferably 14 to 20. Preferably, the alkyl group may be associated with one or more groups R. a Substitution, wherein one or more non-adjacent CH2 groups may be replaced via R a C=CR a C≡C, Si(R) a )2、Ge(R a )2、Sn(R a 2. C=O, C=S, C=Se, C=NRa P(=O)(R) a SO, SO2, NR a OS or CONR a Substitution, and one or more H atoms can be substituted by D, F, Cl, Br, I, CN or NO2.

[0171] R a Each time it appears, it is the same or different of H, D, or an alkyl group having 1 to 20 carbon atoms, a cyclic alkyl or alkoxy group having 3 to 40 carbon atoms, an aromatic ring system having 5 to 60 carbon ring atoms, or a heteroaromatic ring system having 5 to 60 carbon atoms, wherein the H atom may be substituted by D, F, Cl, Br, or I; two or more adjacent substituents R a Here, they can also form monocyclic or polycyclic, aliphatic, aromatic, or heterocyclic systems with each other.

[0172] The chain Y contains at least one carbon-carbon double bond, preferably 1 to 5 carbon-carbon double bonds, more preferably 1 to 3 carbon-carbon double bonds, and even more preferably 1 to 2 carbon-carbon double bonds. Preferably, the compound is selected from the group consisting of: 7-eicosodeoxycholic acid, myristoleic acid, palmitoleic acid, transoleic acid, isoleic acid, codoleic acid, eicosaadienoic acid, eosin, alpha-linolenic acid, eicosatetrienoic acid, erucic acid, or nervonic acid.

Even more preferably, it is selected from eicosaadienoic acid, eosin, alpha-linolenic acid, eicosatetrienoic acid, erucic acid, or nervonic acid.

[0173] In a preferred embodiment of the invention, the ratio of the total weight of the compound to the total weight of the luminescent portion is from 0.6:40 to 1:3, preferably from 1:40 to 1:2, and more preferably from 1.5:40 to 1:1; when the luminescent portion is an inorganic luminescent material, the ratio of the weight of the compound to the weight of the inorganic portion of the inorganic luminescent material is from 0.003 to 3.2, preferably from 0.006 to 2.8, and more preferably from 0.015 to 1.3.

[0174] It is believed that this weight ratio of the compound preferably controls the viscosity / solubility of the composition accordingly. Furthermore, it is particularly advantageous in preventing an increase in the viscosity of the composition and / or maintaining good solubility of the luminescent component during long-term storage.

[0175] -Reactive monomers

[0176] It is believed that lower viscosity is important for manufacturing low-viscosity compositions suitable for inkjet printing. Therefore, (meth)acrylate monomers with viscosity values ​​within the aforementioned parameter range are particularly suitable for manufacturing compositions for inkjet printing. By using these (meth)acrylate monomers in the composition, the composition can still maintain a low viscosity suitable for inkjet printing when mixed with another material with a high loading, such as semi-conductive luminescent nanoparticles.
