Abstract:
1. A photosensitive resin composition containing a (A) soluble polyimide and a (B) (meth)acrylic compound, the (A) soluble polyimide (i) being soluble in an organic solvent and (ii) having a structural unit represented by Formula (1): where R the (B) (meth)acrylic compound containing, as the (A) soluble polyimide having the structural unit represented by Formula (1), a polyimide having a structural unit represented by Formula (3); where R where each R where each R where each R containing, as the (A) soluble polyimide having the structural unit represented by Formula (3), a first polyimide, a second polyimide and a third polyimide, the first polyimide having a recurring unit having a structure represented by Formula (7): where R the second polyimide having a recurring unit having a structure represented by Formula (8): where R the third polyimide having a structure in which R wherein a first polyimide content is in a range of 5 mol % to 80 mol %, a second polyimide content is in a range of 0.5 mol % to 80 mol %, and third polyimide content is the rest, based on 100 mol % of the (A) soluble polyimide; and wherein a log-mean viscosity (0.5 g/100 ml) of the photosensitive resin composition is 0.16 or more.
