| titleOfInvention | Positive photosensitive resin composition, dry film, cured product and printed circuit board |
| abstract | Provided are a positive-type photosensitive resin composition excellent in resolution, a dry film having a resin layer obtained from the composition, a cured product of the composition or the resin layer of the dry film, and a printed wiring board having the cured product. A positive photosensitive resin composition, etc., characterized by containing: (A) a polyamic acid obtained from an acid anhydride and a diamine having a cyclic aliphatic skeleton and an aromatic skeleton, and (B) a photoacid generator . The above-mentioned (A) polyamic acid preferably has the following general formula (I) (in the formula, R 1 is a tetravalent organic group containing a condensed ring of an aromatic ring and an aliphatic hydrocarbon ring, or an aromatic group and an aliphatic ring. A tetravalent organic group of a cyclic hydrocarbon group, R 2 is a divalent organic group, X is a divalent organic group, m is an integer of 1 or more, and n is an integer of 0 or 1 or more.) The compound of the structure shown. |
