Abstract

The present invention provides a photosensitive resin composition that exhibits high liquid repellency even at low curing temperatures and does not experience problems such as ink seepage. [Solution] The photosensitive resin composition of the present invention is a photosensitive resin composition comprising (A) a photopolymerizable compound, (B) a photopolymerization initiator, (C) an alkali-soluble resin, and (D) a liquid repellent, wherein the (C) alkali-soluble resin contains a copolymer resin (C1) having repeating units including an aliphatic polycyclic structure in its main chain, and the (D) liquid repellent contains a compound (D1) having a crosslinking group and having a fluorine atom and / or a siloxane chain.

Claims

The copolymer resin (C1) has repeating units (II) having carboxyl groups, The repeating unit (II) having a carboxyl group contains a repeating unit represented by the following general formula (II-1), 【Chemistry 1】 (In formula (II-1), R 5 (* represents a hydrogen atom or organic group. * represents a bonding bond.) A photosensitive resin composition characterized in that the (D) liquid repellent contains a compound (D1) having a crosslinking group and having a fluorine atom and / or a siloxane chain.

2. The photosensitive resin composition according to claim 1, wherein the content ratio of the copolymer resin (C1) with respect to the total solid content of the photosensitive resin composition is 20% by mass or more.

3. The photosensitive resin composition according to claim 1, wherein the (C) alkali-soluble resin further contains an alkali-soluble resin in addition to the copolymer resin (C1).

4. The photosensitive resin composition according to claim 2, wherein the (C) alkali-soluble resin further contains an alkali-soluble resin in addition to the copolymer resin (C1).

5. The photosensitive resin composition according to any one of claims 1 to 4, further comprising (E) a coloring agent.

6. The photosensitive resin composition according to any one of claims 1 to 4, further containing a solvent.

7. A cured product obtained by curing the photosensitive resin composition according to any one of claims 1 to 4.

8. A partition wall composed of the cured material described in claim 7.

9. An organic electroluminescent element comprising a partition wall as described in claim 8.

10. A color filter comprising the partition wall described in claim 8, further containing luminescent nanocrystalline particles.

11. An image display device comprising a partition wall as described in claim 8.

12. A method for forming a cured product, comprising at least the following steps (1) to (4), using the photosensitive resin composition described in any one of claims 1 to 4. Step (1): A step of applying the photosensitive resin composition onto a substrate to form a coating film. Step (2): A step of exposing at least a portion of the coating film formed in step (1). Step (3): A step of developing the coating film exposed in step (2). Step (4): A step of firing the coating film developed in step (3).

13. The method for forming a cured product according to claim 12, wherein the firing temperature in step (4) is 140°C or lower.

14. A method for forming a cured product according to claim 12, further comprising a post-exposure step of exposing the coating film developed in step (3) after step (3).
