<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a colored wood free from unevenness of coloring and easy to handle, the colored wood, veneer, and building materials. <P>SOLUTION: Impregnation is performed under reduced pressure and pressure while immersing a lamina in acetone of 10 in solubility index and then the lamina is pulled up from the acetone and is subjected to pressure reduction processing to remove surplus acetone in the lamina. Impregnation is performed under reduced pressure and pressure while immersing the lamina in a dye solution containing 1 wt.% of a semi level-dyeing type acid dye, 20 wt.% of urea as a dissolution aid, and 79 wt.% of water as a dye solvent, and then the lamina is pulled up from the dye solution and is subjected to pressure reduction processing to remove surplus dye solution in the lamina. Many laminas L so formed are laminated and bonded to form a flitch F, and the flitch F is cut by a slicer to form 0.3 mm-thick wet veneer SP. <P>COPYRIGHT: (C)2013,JPO&INPIT |
