Abstract

PURPOSE:To facilitate the forming of a sharp stereoscopic pattern by a method wherein a transfer sheet having a coloring layer on a releasable surface of a release substrate is overlapped on a substrate to be subjected to transfer through an ionizing radiation curing resin layer, the ionizing radiation curing resin layer is cured by the irradiation of an ionizing radiation from the ionizing radiation transmitting sheet as the transfer sheet, and the release substrate is peeled. CONSTITUTION:A release substrate 2 is overlapped on a substrate 5 to be subjected to transfer through an ionizing radiation curing resin layer 4, and the both are brought into close contact with each other, thereafter being irradiated with an ionizing radiation 6 from the release substrate 2. Then, the ionizing radiation curing resin layer 4 is cured by the irradiation of the ionizing radiation 6. After the irradiation of the ionizing radiation 6, the release substrate 2 is released; a coloring layer 3 is transferred to the cured ionizing radiation curing resin layer 4. Thereafter, an ionizing radiation curing resin layer 4a is applied on the surface of the transfer substrate 5, and a transfer sheet 1a is overlappedly brought into close contact with the ionizing radiation curing resin layer 4a. After the ionizing radiation curing resin layer 4a is cured by the irradiation of an ionizing radiation from a release substrate 2a, the release substrate 2a is peeled. In this manner, a stereoscopic pattern forming material 7 having the coloring layers 3, 3a spaced a fixed distance from each other can be obtained.
