Abstract: UV-curable photosensitive coating technology has special requirements to the object being cured，the curing depth and adhesives，especially for that applied in high-speed automated production lines. On the basis of defect analysis of this technology，the present paper reports the preparation of UV-curable epoxy-acrylic photosensitive resin using epoxy resin and acrylic acid as starting materials，triphenylphosphine as catalyst，and p-benzenediol as inhibitor. Then epoxy-acrylate photosensitive coating was compounded by mixing the resin，reactive diluent and photosensitizer. Influences of the mole ratio，the feeding mode and temperature on resin synthesis，as well as the impact of sensitizer on coating behabiour are also discussed.
