PROBLEM TO BE SOLVED: To provide an insulating film forming material comprising a component capable of constituting a polybenzazole having a high degree of cross-linking and capable of easily forming a film thickness particularly required for use as an interlayer insulating film, and an insulating material formed from the material. Provide a membrane. SOLUTION: The insulating film forming material of the present invention is prepared by adding the following formula (1) to an organic solvent. Embedded image (Wherein, X represents a hydrogen atom, a hydrocarbon group, or R 4 , R 1 to R 4 are the same or different and represent a carboxyl group or the like which may be protected by a protecting group, and Y 1 to Y 4 4 is the same or different and represents a single bond or a divalent aromatic cyclic group) An adamantane polycarboxylic acid derivative represented by the following formula (2): Embedded image (In the formula, ring Z represents a monocyclic or polycyclic aromatic ring, and R 5 to R 8 are substituents bonded to ring Z and may be the same or different and may be protected by a protecting group. Shows good amino group etc.) And a polymerizable composition obtained by dissolving the aromatic polyamine derivative represented by the formula (1). [Selection diagram] None |
