<p>PURPOSE: To obtain a three-dimensional image forming method for forming an arbitrary three-dimensional image on an arbitrary transfer medium, obviating the need of considering the state of preserving or handling the transfer medium after the forming of the three-dimensional image, and realizing a low running cost. CONSTITUTION: A substrate 11 is perforated with holes 15 by a thermal head 13. A curable composition 23 is put on the substrate 11 and transferred to a transfer medium in such a manner that it is rubbed into by a squeegee 25. Thereafter, a UV radiation is emitted from a light source. As the curable composition 23, a three-dimensional image forming ink is used, that is prepared by mixing 5 pts.wt. silica in photosetting ink prepared by mixing 10 pts.wt. trimethylolpropane triacrylate and 1 pts.wt. 4-methylthioether-2-methyl-2- molpholinopropiophenone to be improved in thixotropy and kept at a height of 0.1mm or more at the time of transferring. In this manner, one can feel the clear irregularities of the obtained three-dimensional image by the touch of a finger.</p> |
