ABSTRACT:
The present invention relates to a resist ink composition characterized by comprising a specific unsaturated polycarboxylic acid resin (A) or a specific unsaturated polycarboxylic acid/urethane resin (A'), a photopolymerization initiator (B), a diluent (C), and a curing component (D) and a cured article prepared therefrom.
In the formation of a solder resist pattern via selective UV-exposure through a patterned film followed by development of the unexposed part, the composition of the present invention is excellent in developability even though at a small acid value (mg KOH/g) or over a prolonged drying time and shows a resistance of the exposed part against the developing solution. Further, a cured article prepared therefrom is excellent in electroless gold plating resistance and fully satisfactory in adhesion and soldering heat resistance.
