Abstract
A photocurable and thermosetting composition for an ink jet system comprises (A) a monomer having a (meth)acryloyl group and a thermosetting functional group in its molecule, (B) a photoreactive diluent having a weight-average molecular weight of not more than 700 other than the component (A) mentioned above, and (C) a photopolymerization initiator and has a viscosity of not more than 150 mPa·s at 25° C. A solder resist pattern is directly drawn on a printed circuit board by means of an ink jet printer using the above-mentioned composition, and the pattern is primarily cured by irradiation with an active energy ray and then further cured by heating.
