| abstract | (57) [Summary] [Solution] The following formula (1) Wherein n is 0 or 1, R and R ′ are (R 1 to R 21 represent a hydrogen atom and / or an alkyl group (—CH 3 , —C 2 H 5 , —nC 3 H 5 , —CH (C H 3) 2, -nC 4 H 9, -CH (CH 3) C 2 H 5, -C (CH 3 ) 3 ), wherein R 1 to R 21 may be the same or different, but contain at least one or more alkyl groups. And R and R 'may be the same or different from each other, Ar has 6 to 27 carbon atoms, and is an aliphatic group, a monocyclic aliphatic group, a condensed polycyclic aliphatic group, a monocyclic aliphatic group. A tetravalent group selected from the group consisting of a formula aromatic group, a condensed polycyclic aromatic group, and a non-condensed polycyclic aromatic group in which aromatic groups are connected to each other directly or by a crosslinking member; Is from 3 to 100 and indicates the degree of polymerization. ] The photosensitive polyimide which has a repeating structural unit represented by these. The polyimide obtained by the present invention is a novel substance having an alkyl group in a repeating structural unit. This polyimide is a very useful new polyimide having not only physical properties such as heat resistance but also new physical properties such as solvent solubility and photosensitivity. |
