Abstract

Provided is a photosensitive resin composition from which a cured product having thin film thickness, excellent light-shielding properties, and high surface hardness is obtained. A a cured film and a method for producing the same, a method for producing a resin pattern, and an LCD device, an organic EL display device, an infrared cut filter, or a solid-state imaging device are also provided. The photosensitive resin composition includes a polymer component including at least one of categories (1) or (2), a photoacid generator, a solvent, and titanium black, wherein (1) includes (a1) a constitutional unit containing a group in which an acid group is protected by an acid-decomposable group, and (a2) a constitutional unit containing a crosslinkable group, and (2) includes (a1) a constitutional unit containing a group in which an acid group is protected by an acid-decomposable group, and (a2) a constitutional unit containing a crosslinkable group.

First claim

What is claimed is:

1. A photosensitive resin composition comprising:
(Component A) a polymer component including polymers satisfying at least one of (1) or (2) below,
(1) a polymer having (a1) a constitutional unit containing a group in which an acid group is protected by an acid-decomposable group, and (a2) a constitutional unit containing a crosslinkable group;
(2) a polymer having (a1) a constitutional unit containing a group in which an acid group is protected by an acid-decomposable group, and a polymer having (a2) a constitutional unit containing a crosslinkable group;
(Component B) a photoacid generator;
(Component C) a solvent; and
(Component S) titanium black.

2. The photosensitive resin composition according to claim 1 , wherein the crosslinkable group is at least one selected from the group consisting of an epoxy group, an oxetanyl group, —NH—CH 2 —OR 1 in which R 1 represents an alkyl group having 1 to 20 carbon atoms, an ethylenically unsaturated group, and a blocked isocyanate group.

3. The photosensitive resin composition according to claim 1 , wherein the crosslinkable group equivalent in the photosensitive resin composition is 250 to 1,000 per 1 g of organic solid content.

4. The photosensitive resin composition according to claim 1 , further comprising (Component D) a dispersant.

5. The photosensitive resin composition according to claim 1 , wherein the content of Component S is 40 mass % to 80 mass % based on the total solid content of the photosensitive resin composition.

6. The photosensitive resin composition according to claim 1 , further comprising (Component E) a crosslinking agent.

7. The photosensitive resin composition according to claim 1 , wherein Component B is an oxime sulfonate compound.

8. A method for producing a cured product, comprising in this order:
applying the photosensitive resin composition according to claim 1 onto a substrate;
removing a solvent from the applied resin composition; and
heat-treating the resin composition freed from the solvent, or irradiating the resin composition freed from the solvent with actinic rays.

9. A method for producing a resin pattern, comprising in this order:
applying the photosensitive resin composition according to claim 1 onto a substrate;
removing a solvent from the applied resin composition;
patternwise exposing the resin composition freed from the solvent to actinic rays; and
developing the exposed resin composition and the unexposed resin composition with an aqueous developer.

10. A cured film obtained by curing the photosensitive resin composition according to claim 1 .

11. The cured film according to claim 10 , which is a light-shielding color filter.

12. A liquid crystal display device having the cured film according to claim 10 .

13. An organic EL display device having the cured film according to claim 10 .

14. An infrared cut filter having the cured film according to claim 10 .

15. A solid-state imaging device having the cured film according to claim 10 .
