| titleOfInvention | New polyimide and positive photosensitive resin composition |
| abstract | An object of the present invention is to provide a positive photosensitive resin composition capable of forming a polyimide film having excellent storage stability, high-resolution pattern forming properties, and excellent physical properties such as strength and heat resistance. (A) General formula (I) Embedded image (Wherein n is a rational number in the range of 1 <n <99 and represents the copolymerization ratio in the resin. R 1 and R 2 are each independently a hydrogen atom or an alkyl having 1 to 20 carbon atoms. R 3 represents a divalent aromatic group having at least one sulfonic acid group and / or an organic base salt of the sulfonic acid group, Z represents a monocyclic aromatic group, a condensed polycyclic aromatic group A repeating unit represented by the formula: and a tetravalent group selected from the group consisting of a non-condensed polycyclic aromatic group in which an aromatic group is directly or interconnected by a crosslinking member. And (b) a positive photosensitive resin composition comprising a photosensitive agent. [Selection diagram] None |
