Abstract:
1. A photosensitive resin film in an uncured state, comprising: (A) an alkali-soluble copolymer comprising: (B) a compound having at least one ethylenically unsaturated double bond, and (C) a radiation-sensitive radical polymerization initiator by the use of which a coating film having a dry film thickness of 70 μm in an uncured state has a 365 nm radiation transmittance of not less than 10% and a 405 nm radiation transmittance of not less than 60%, wherein the radiation-sensitive radical polymerization initiator (C) is contained in an amount of 20 to 40 parts by weight based on 100 parts by weight of the component (A), and a dry film thickness of said photosensitive resin film is not less than 50 μm.
