感光性树脂组合物、干膜和印刷布线板
摘要：
本发明提供一种感光性树脂组合物，其通过固化而成为固化物，能够抑制用氧化剂对该固化物的表面进行处理时的固化物层的腐蚀，能够减少过度的表面粗糙且能够抑制表面变得不均匀。感光性树脂组合物含有：含羧基树脂(A)，在一分子中具有至少一个烯键式不饱和键的不饱和化合物(B)，光聚合引发剂(C)，环氧化合物(D)，有机填料(E)，二氧化硅(F)以及三嗪树脂(G)。二氧化硅(F)的平均一次粒径为1nm～150nm。
摘要（英）：

Provided is a photosensitive resin composition from which a cured product is obtained when subjected to curing and in which it is possible to suppress corrosion of a cured layer when the surface of the cured product is treated with an oxidizing agent, to minimize excessive surface roughness, and to prevent the surface from becoming uneven. This photosensitive resin composition comprises: a carboxyl-containing resin (A); an unsaturated compound (B) containing at least one ethylenically unsaturated bond per molecule; a photopolymerization initiator (C); an epoxy compound (D); an organic filler (E); silica (F); and a triazine resin (G). The silica (F) has an average primary particle diameter of 1-150 nm.
