摘要

The optical hardenable thermosetting metaplasia composition for the ink jet, (A) (the monomer which possesses the meta) akuriroiru basis and the thermosetting metaplasia functional group, (B) the description above of weight average molecular weight 700 or less (A) the optical reactivity diluent other than the component, and (C) contains the photo polymerization initiator inside the molecule, viscosity is below 150mPa s with the 25C. Making use of the said composition, with the ink jet printer it draws sorudarejisutopatan directly in the printed circuit board, it makes harden primarily by irradiating the activation energy line, after that furthermore it makes heat makes harden.
