Composition for pattern formation

Abstract

A composition for pattern formation which comprises: a triazine-ring-containing polymer that includes a repeating unit structure represented by formula (1) and has at least one triazine ring terminal, at least some of the triazine ring terminal having been blocked with an arylamino group substituted by a hydroxyl group; a crosslinking agent; fine inorganic particles each having an alkali-reactive group on the surface; and an organic solvent. (In formula (1), R and R' each independently represent a hydrogen atom or an alkyl, alkoxy, aryl, or aralkyl group, Q represents a C3-C30 divalent group having a ring structure, and * indicates a bond.)

7. The pattern-forming composition according to claim 1, for use in the light extraction layer of an organic electroluminescent element.

8. A cured product made from a pattern-forming composition according to any one of claims 1 to 7.

9. An electronic device comprising a substrate and a cured product according to claim 8 formed on the substrate.

10. The electronic device according to claim 9, which is an organic electroluminescent device.

11. An optical member comprising a base material and a cured product according to claim 8 formed on the base material.

12. A method for producing a pattern, characterized by applying a pattern-forming composition according to any one of claims 1 to 7 to a substrate, evaporating an organic solvent, irradiating with light through a mask on which a pattern has been formed, developing the material, and then firing it.
