Patent ID: 8586284

Claim:
A photosensitive resin composition comprising: (A) 100 parts by weight of a binder polymer having 10-65 parts by weight of a divalent group represented by the following formula (I), 5-55 parts by weight of a divalent group represented by the following formula (II) and 15-50 parts by weight of a divalent group represented by the following formula (III); (B) a photopolymerizing compound; (C) a photopolymerization initiator; and (D) at least one sensitizing dye with a maximum absorption wavelength of 370-420 nm selected from the group consisting of pyrazolines, anthracenes, coumarins, xanthones, triazoles, triazines, thiophenes and naphthalimides, wherein, in formula (I), formula (II) and formula (III), R 1 , R 3 and R 5 each independently represent hydrogen or a methyl group, R 2 represents C1-3 alkyl, C1-3 alkoxy, hydroxyl, amino or a halogen atom, R 4 represents an optionally substituted alicyclic hydrocarbon, optionally substituted aromatic hydrocarbon or optionally substituted heterocyclic group, m represents an integer of 0-5, and when m is 2-5, the multiple R 2 groups may be the same or different.
