Abstract

The present invention relates to a process for fabricating cured composition.

Claims (32)

1 . Process for fabricating cured composition comprising at least following steps;

a) irradiating a composition with a light as a 1 st light irradiation;

b) irradiating the composition with a light as a 2 nd light irradiation;

wherein the composition comprises at least one light emitting moiety and a reactive monomer;

wherein the intensity of the light of the 1 st light irradiation and the intensity of the light of the 2 nd light irradiation satisfies the following formula (I):

The intensity of light of the 1 st light irradiation<the intensity of light of the 2nd light irradiation  (I).

2 . Process of claim 1 , wherein the peak light wavelength of the light of the 1 st light irradiation and the peak light wavelength of the light of the 2 nd light irradiation are, independently of each other, in the range from 200 to 450 nm.

3 . Process of claim 1 , wherein the irradiation time of the 1 st light irradiation at step a) is in the range from 1 second to 500 seconds and the irradiation time of the 2 nd light irradiation time at step b) is in the range from 1 second to 500 seconds.

4 . Process of claim 1 , wherein the intensity of light of the 1 st light irradiation at step (a) is in the range from 0.1 mW/cm 2 to 20 mW/cm 2 and the intensity of light of the 2 nd light irradiation at step (b) is in the range from 20 mW/cm 2 to 100 W/cm 2 .

5 . Process of claim 1 , wherein the composition contains a plurality of light emitting moieties.

6 . Process of claim 1 , wherein the composition comprises scattering particles, wherein the total amount of the scattering particles is 10 wt % or less based on the total amount of the solid contents of the composition.

7 . Process of claim 1 , wherein the reactive monomer is a (meth)acrylate monomer selected from a mono-(meth)acrylate monomer, a di-(meth)acrylate monomer or a tri-(meth)acrylate monomer.

8 . Process of claim 7 , wherein the composition further comprises an another (meth)acrylate monomer, which is different from the (meth)acrylate monomer of claim 7 .

9 . Process of claim 7 , wherein the (meth)acrylate monomer of chemical formula (II) is in the composition and the mixing ratio of the (meth)acrylate monomer of claim 7 represented by chemical formula (I) to the (meth)acrylate monomer of chemical formula (II) is in the range from 1:99 to 99:1 (formula (I):formula (II)),

wherein

X 1 is a non-substituted or substituted alkyl group, aryl group or an alkoxy group or an ester group;

X 2 is a non-substituted or substituted alkyl group, aryl group or an alkoxy group or an ester group;

R 1 is a hydrogen atom, halogen atom of Cl, Br, or F, methyl group, alkyl group, aryl group, alkoxy group, ester group, or a carboxylic acid group;

R 2 is a hydrogen atom, halogen atom of Cl, Br, or F, methyl group, alkyl group, aryl group, alkoxy group, ester group, or a carboxylic acid group;

X 3 is a non-substituted or substituted alkyl group, aryl group or an alkoxy group;

R 5 is a hydrogen atom, halogen atom of Cl, Br, or F, methyl group, alkyl group, aryl group, alkoxy group, ester group, or a carboxylic acid group.

10 . Process of claim 1 , wherein the boiling point (B.P.) of said (meth)acrylate monomer of chemical formula (I) and/or chemical formula (II) is 250° C. or more.

11 . Process of claim 1 , wherein the viscosity of the composition is 35 cP or less at room temperature.

12 . Process of claim 1 , wherein said light emitting moiety is an organic light emitting material and/or an inorganic light emitting material.

13 . Process of claim 1 , wherein the composition comprises a solvent 10 wt % or less based on the total amount of the composition.

14 . A cured composition obtained or obtainable from the process of claim 1 .

15 . A layer obtained or obtainable from the process of claim 1 .

16 . A layer containing light emitting moieties, a matrix material and scattering particles, wherein the total amount of the light emitting moieties is in the range from 0.1 wt. % to 90 wt. % based on the total amount of the layer, wherein the total amount of the scattering particles is 10 wt % or less based on the total amount of the layer.

17 . The layer of claim 15 , wherein the layer thickness of the layer is in the range from 1 to 50 um.

18 . A color conversion device ( 100 ) comprising at least a 1 st pixel ( 161 ) partly or fully filled with the cured composition of claim 14 , and a bank ( 150 ) comprising at least a polymer material.

19 . An optical device ( 300 ) containing at least one functional medium ( 320 , 420 , 520 ) configured to modulate a light or configured to emit light, and the color conversion device ( 100 ) of claim 18 .

20 . A color conversion device ( 100 ) comprising at least a 1 st pixel ( 161 ) partly or fully filled with the layer of claim 15 , and a bank ( 150 ) comprising at least a polymer material.
