<p>PURPOSE:To obtain a colored picture of which process is simplified and quality is improved by using a water soluble resin layer applied on a transparent supporting member through an oil soluble resin layer as a mask and coloring the picture with oil soluble dye and then water siluble dye. CONSTITUTION:A oil soluble resin layer 2 is formed on a transparent supporting member 1 such as glass. The oil soluble resin layer 2 is coated with a photosensitive water soluble resin layer 3. After forming the water soluble resin layer 3, a mask with a prescribed shape is adhered to the layer 3, and the masked layer is exposed and developed with hot water, so that a patterned releaf picture of water soluble resin layer 3' is formed. Subsequently, a dye which can be sublimated or evaporated through heat melting is transferred to the oil soluble resin layer to dye the layer through a gap part by using the patterned water soluble resin layer 3' as a mask to form the 1st colored picture 4. The 2nd colored picture 5 is formed by dipping the 1st colored picture into an aqueous solution in which an acid dye is resolved.</p> |
