The present invention relates to a UV curable resin composition, comprising a UV curable resin, an initiator, a UV-responsive acrylic or vinyl monomer, and an inorganic powder, but a thermal initiator capable of generating radicals effectively by heat generated in an ultraviolet curing process as an initiator. The present invention provides an ultraviolet curable resin composition that can be preferably used as a lower filler in a printed circuit board by increasing the curability by mixing with a photoinitiator to impart adhesion to the lower substrate. |
