Disclosed is a phosphazene compound and a photosensitive resin composition. The phosphazene compound is obtained by reacting a phenoxyphosphazene compound (A-1) having a phenolic hydroxyl group and/or a cross-linked phenoxyphosphazene compound (A-2) obtained by cross-linking the phenoxyphosphazene compound (A-1) with an epoxy compound (B) having an unsaturated double bond and/or an isocyanate compound (C), wherein the phosphazene compound has an unsaturated double bond in its molecule. The photosensitive resin composition includes at least: a soluble polyimide resin (G-1) having a carboxyl group and/or a hydroxyl group and is soluble in an organic solvent, as the polyimide resins (G); and a phenoxyphosphazene compound (H-1) having a phenolic hydroxyl group and/or a cross-linked phenoxyphosphazene compound (H-2), which is obtained by cross-linking the phenoxyphosphazene compound (H-1) and has at least one phenolic hydroxyl group, as the phosphazene compound (H), and the photosensitive resin composition further includes a (meth)acrylic compound (L).
本发明公开了一种膦氮化合物和一种感光树脂组合物。膦氮化合物是由具有酚羟基的苯氧基膦氮化合物(A-1)和/或通过将苯氧基膦氮化合物(A-1)与具有不饱和双键的环氧化合物(B)和/或异氰酸酯化合物(C)交联而得到的交联苯氧基膦氮化合物(A-2)反应得到的,其中膦氮化合物分子中具有不饱和双键。光敏树脂组合物至少包括具有羧基和/或羟基并可溶于有机溶剂的可溶性聚酰亚胺树脂 (G-1),如聚酰亚胺树脂 (G);和具有酚羟基的苯氧基膦氮化合物(H-1)和/或交联苯氧基膦氮化合物(H-2),后者通过交联苯氧基膦氮化合物(H-1)而得到,具有至少一个酚羟基,作为膦氮化合物(H),感光树脂组合物还包括(甲基)丙烯酸化合物(L)。
