AI Technical Summary

Technical Problem

Existing radiosensitive linear compositions suffer from decreased storage stability when silane coupling agents are added to improve adhesion, making it difficult to balance adhesion and storage stability.

Method used

A hardened film is formed by using a composition containing an alkali-soluble polymer, a radiosensitive linear compound, a solvent, and an imino-containing organooxysilane compound, through coating, solvent removal, radiation irradiation, development, and heat treatment.

Benefits of technology

A hardened film with excellent radiation sensitivity and storage stability, as well as good development adhesion, is formed, making it suitable for liquid crystal display devices and organic electroluminescent display devices.
