    • An ultraviolet-curable type photo solder resist ink comprises the following components (A) to (E). That is. the component (A) is an ultraviolet-curable resin having at least two ethylenically unsaturated groups and a carboxyl group per one molecule thereof. The component (B) is an epoxy compound having at least two epoxy groups per one molecule thereof. The component (C) is at least one selected from a compound having at least one carboxyl group and a polycarboxylic acid anhydride. The component (D) is a photopolymerization initiator. The component (E) is a diluent. This photo solder resist ink shows a good developing property even when a developer having a pH value of about 10 is used, and is excellent in a storage stability of resist, electrical corrosion resistance, electric performance, chemical resistance, plating resistance, heat resistance to solder, adhesion, and pencil hardness.
    • 紫外线固化型光阻油墨包含以下组分(A)至(E)。 那是。 组分(A)是每分子具有至少两个烯属不饱和基团和羧基的紫外线固化树脂。 组分(B)是每分子具有至少两个环氧基的环氧化合物。 组分(C)是选自具有至少一个羧基的化合物和多元羧酸酐中的至少一种。 组分(D)是光聚合引发剂。 组分(E)是稀释剂。 即使使用pH值为10左右的显影剂,该光阻焊油墨显示出良好的显影性,抗蚀剂的保存稳定性,电腐蚀性,电性能,耐化学性,耐电镀性,耐热性 焊料,附着力和铅笔硬度。
