Abstract

A photosensitive resin composition includes (A) a binder resin including an epoxy resin; (B) a photopolymerizable monomer; (C) a photopolymerization initiator; (D) a colorant including a dye represented by the following Chemical Formula 1, wherein in the above Chemical Formula 1, each substituent is the same as defined in the detailed description; and (E) a solvent.

First claim

What is claimed is:

1. A photosensitive resin composition, comprising:
(A) a binder resin including an epoxy resin;
(B) a photopolymerizable monomer;
(C) a photopolymerization initiator;
(D) a colorant including a dye represented by the following Chemical Formula 1; and
(E) a solvent:

wherein, in the Chemical Formula 1,
M is Cu, Zn, Co, or Mo,
R 1 to R 16 are the same or different and are each independently hydrogen, halogen, substituted or unsubstituted C 1 to C 20 C 1 to C 20 alkyl, substituted or unsubstituted C 1 to C 20 C 1 to C 20 alkoxy, substituted or unsubstituted C 6 to C 20 C 6 to C 20 aryl, or substituted or unsubstituted C 6 to C 20 C 6 to C 20 aryloxy,
wherein at least one of R 1 to R 16 is substituted or unsubstituted C 1 to C 20 alkoxy, and at least one of R 1 to R 16 is substituted or unsubstituted C 6 to C 20 aryloxy represented by the following Chemical Formula 2:

wherein, in the Chemical Formula 2,
R 17 to R 25 are the same or different and are each independently hydrogen, halogen, or substituted or unsubstituted C 1 to C 8 alkyl.

2. The photosensitive resin composition of claim 1 , wherein the C 1 to C 20 alkoxy is methoxy, ethoxy, propoxy, butoxy, pentyloxy, hexyloxy, heptyloxy, octyloxy, nonyloxy, or decyloxy.

3. The photosensitive resin composition of claim 1 , wherein at least one of R 1 to R 4 is substituted or unsubstituted C 6 to C 20 aryloxy,
at least one of R 5 to R 8 is substituted or unsubstituted C 6 to C 20 aryloxy,
at least one of R 9 to R 12 is substituted or unsubstituted C 6 to C 20 aryloxy, and
at least one of R 13 to R 16 is substituted or unsubstituted C 1 to C 20 alkoxy.

4. The photosensitive resin composition of claim 1 , wherein at least one of R 1 to R 4 is substituted or unsubstituted C 6 to C 20 aryloxy,
at least one of R 5 to R 8 is substituted or unsubstituted C 1 to C 20 alkoxy,
at least one of R 9 to R 12 is substituted or unsubstituted C 1 to C 20 alkoxy, and
at least one of R 13 to R 16 is substituted or unsubstituted C 1 to C 20 alkoxy.

5. The photosensitive resin composition of claim 1 , wherein at least one of R 1 to R 4 is substituted or unsubstituted C 6 to C 20 aryloxy,
at least one of R 5 to R 8 is substituted or unsubstituted C 1 to C 20 alkoxy,
at least one of R 9 to R 12 is substituted or unsubstituted C 6 to C 20 aryloxy, and
at least one of R 13 to R 16 is substituted or unsubstituted C 1 to C 20 alkoxy.

6. The photosensitive resin composition of claim 1 , wherein at least one of R 1 to R 4 is substituted or unsubstituted C 6 to C 20 aryloxy,
at least one of R 5 to R 8 is substituted or unsubstituted C 6 to C 20 aryloxy,
at least one of R 9 to R 12 is substituted or unsubstituted C 1 to C 20 alkoxy, and
at least one of R 13 to R 16 is substituted or unsubstituted C 1 to C 20 alkoxy.

7. The photosensitive resin composition of claim 1 , wherein the dye represented by Chemical Formula 1 is represented by one of the following Chemical Formulae 3 to 6:

wherein, in Chemical Formulae 3 to 6,
M is Cu, Zn, Co or Mo.

8. The photosensitive resin composition of claim 1 , wherein the dye represented by Chemical Formula 1 is a mixture of at least two of compounds represented by the following Chemical Formulae 3 to 6:

wherein, in Chemical Formulae 3 to 6,
M is Cu, Zn, Co or Mo.

9. The photosensitive resin composition of claim 1 , comprising the dye represented by Chemical Formula 1 in an amount of about 2 wt % to about 3 wt % based on the total weight of the photosensitive resin composition.

10. The photosensitive resin composition of claim 1 , wherein the dye represented by Chemical Formula 1 is a green dye.

11. The photosensitive resin composition of claim 1 , wherein the colorant further comprises a pigment.

12. The photosensitive resin composition of claim 11 , comprising the dye and the pigment in a weight ratio of about 3:7 to about 7:3.

13. The photosensitive resin composition of claim 1 , wherein the binder resin further comprises an acrylic-based binder resin.

14. The photosensitive resin composition of claim 1 , wherein the photosensitive resin composition comprises:
(A) about 1 wt % to about 30 wt % of the binder resin;
(B) about 1 wt % to about 20 wt % of the photopolymerizable monomer;
(C) about 0.1 wt % to about 10 wt % of the photopolymerization initiator;
(D) about 40 wt % to about 70 wt % of the colorant; and
