ABSTRACT:
In coloration of a shaped article composed of a curable resin, the addition operation can be reliably conducted and a reliable coloration effect can be obtained in both the single-color addition and in the multicolor addition. A liquid-phase, non-colored photo-curable resin is cured by irradiation with laser light and a lowermost layer5nis formed. A liquid-phase, photo-curable resin is applied on the upper surface thereof and a colored layer5n-1comprising a cured non-colored region and a liquid-phase pool region is formed. A color ink is drop-wise added to the liquid-phase pool region. The pool region is irradiated with laser light and cured to the same hardness as that of the non-colored region. A block-like coating film having the prescribed thickness if formed from the surface coating film produced by the color ink covering the pool region. As a result, the formation of the next layer (colored layer5n-2) on the upper surface of colored layer5n-1can be conducted without obstacles. Colored layer5n-2through colored layer53are formed by repeating this process, a colored layer52is formed on the upper surface of colored layer53, and then the uppermost layer51is formed on the colored layer52.
