<p>Photosensitive resins used in photoengraving materials, printing ink, coating compositions, adhesives and other materials are cured to form satisfactory dry layers by using, as the ultraviolet light source, a flash discharge lamp which is a cold light source capable of instantly producing the total amount of light required, in which the emission energy J (joule) is controlled within the range of 0.02 ? J/S ? 8 wherein S (cm2) denotes the area to be irradiated, or within the range of 0.002 ? J/Sd ? 2 wherein S (cm2) denotes the area to be irradiated and d (.mu.m) stands for the thickness of the photosensitive resin layer after curing.</p> |
