Abstract
The object of the present invention is to provide a photosensitive resin composition which is excellent in: storage stability in a long-term storage; microfabricability; developability; low-temperature curability; flexibility in a cured film; electrical insulation reliability; solder heat resistance; resistance to an organic solvent; and flame retardancy and low in post-curing warpage when processed into a substrate. The object can be attained by use of a photosensitive resin composition production kit which includes at least two or more components including an A component and a B component. The A component contains a (A) compound having a carboxyl group. The B component contains a (B) compound having a reactive group which is reactive to a carboxyl group, a (C) oxime ester photopolymerization initiator, and a (D) compound having a photosensitive group but no carboxyl group.
