<p>The present invention relates to a process for producing a patterned decorative material using moldings of ultraviolet (UV)-curable resins, which process allows production of various decorative materials having desired pattern forms for the decoration of windows of various electric and electronic instruments such as mobile phones and MP3 players and other accessories, by applying a UV-curable resin on a substrate formed of a plastic film, a polycarbonate sheet, an acrylic sheet, a metal sheet, a glass sheet or thelike; forming a UV-curable organic mold or an elastic mold of polydimethylsiloxane, having a pattern form formed thereon; pressingthe organic mold or elastic mold against the UV-curable resin on the substrate and irradiating UV rays to form a pattern form. The process according to the invention is advantageous in that the risk of scar and defect generation on the patterning mold is significantly low, the yield and economic efficiency are high, and large-area patterned decorative materials of high quality can be easily produced with excellent workability and productivity, compared with conventional methods of thermal pressing and adhesion using pattern form master rolls. The process according to the invention also allows production of decorative materials manifesting pattern images of higher brightness compared with conventional decorative materials.</p> |
