[PROBLEMS] To provide a thermosetting non-photosensitive resin composition. [MEANS FOR SOLVING PROBLEMS] A self-crosslinking copolymer having a structural unit represented by the following formula (1) and formula (2), and a non-photosensitive resin composition containing a solvent. (Wherein, R 0 each independently represents a hydrogen atom or a methyl group, X represents a group -O- or -NH-, R 1 represents an alkylene group of a single bond or a carbon atom number of 1 to 6, R 2 is A represents an integer of 1 to 5, b represents an integer of 0 to 4, a and b satisfy 1? A + b? 5, b represents 2, 3 or 4, R 2 may be different from each other, R 3 represents a divalent organic group represented by the following formula (I), (II) or (III), and R 4 represents an organic group having an epoxy group . (Wherein c represents an integer of 0 to 3, d represents an integer of 1 to 3, and e each independently represent an integer of 2 to 6.) |
