<p>PROBLEM TO BE SOLVED: To obtain a UV-curable surface wrinkle-forming ink capable of forming wrinkle patterns excellent in design by forming innumerable contraction wrinkles having an almost certain size at the same time through curing, when a coating film applied by screen printing, curtain coating and the like on a material such as a plastic, a glass, a metal or the like is cured. SOLUTION: This UV-curing and surface wrinkle-forming ink is obtained by using a >=2 functional epoxy compound as an ink vehicle and a photo- cationic catalyst having low catalytic activity when irradiated with UV rays, i.e., mainly acting on curing of the coated surface as the photo cationic catalyst. Thus, the curing and contraction of the surface are taken place and numerous number of wrinkles having almost certain size are formed on the surface.</p> |
