点を有していた。 A plurality of dyed material veneers are laminated and pressed together using an adhesive to form a composite fritchi, and this composite fritchi is sliced in a predetermined direction that intersects with the laminated surface to match the cut surface of the material veneer with the wood grain. In the conventional manufacturing method of artificial decorative veneer, which is exposed as a pattern on the wood surface and the growth ring lines of the wood grain pattern are made to stand out due to the difference in dye density between the outer surface and the inside of the material veneer, The disadvantage is that the wood grain pattern of the resulting artificially decorated veneer changes color and discolors due to tanning of the wood parts due to the effects of ultraviolet rays, decomposition of dyes, and other changes over time, and the dyeing of the entire surface of the wood becomes uniform, making the growth ring lines unclear. It had

の経年変色が小さく、天然木にみられるような木
質部における経年変色の大きい自然なやけ具合に
ならず自然感に欠けるという欠点が残る。 In order to prevent such discoloration and discoloration of the wood grain pattern, a method has previously been proposed in which the surface of the artificially decorated veneer is coated with a solution or paint containing imidazole (C 3 H 4 N 2 ) or its acid addition salt. However, there remains a drawback that the overall wood grain pattern has little discoloration over time, and it lacks a natural look because it does not have the natural discoloration that occurs in the woody parts of natural wood, which has a large discoloration over time.

得るものである。 An embodiment of the invention is shown in FIGS. 1 and 2. In other words, the method for manufacturing this artificially decorated veneer is as follows:
The material veneer 1 shown in FIG. 1A is immersed in a dyeing bath 2 containing 0.05% imidazole as shown in FIG. As shown in Figure C, it is laminated on the uneven mold 3 using an adhesive and bonded by pressure to obtain an uneven assembly frit 4, and this uneven assembly frit 4 is laminated from the direction intersecting the laminated surface as shown in Figure D. By slicing, an artificial decorative veneer 5 as shown in FIG. 2 is obtained, in which the cut surface of each material veneer 1 is expressed as a wood grain pattern on the wood surface.
この実施例におけるそのほかの具体的条件は以
下のとおりである。 Other specific conditions in this example are as follows.
素材単板：厚み0.8mmのアガチス材

「スミノールミリングブラウン」）
濃度−２〜３％
溶媒−水

よるものであつてもよい。Material veneer: 0.8 mm thick agathis wood Dyeing conditions: Dye - Acid dye ("Sminol Milling Brown" manufactured by Sumitomo Chemical Co., Ltd.) Concentration - 2 ~ 3% Solvent - Water temperature - 3 Room temperature (15 ~ 20°C) Bath ratio -20 hours - 3 hours The additives added to the dyeing bath 2 are not limited to the above-mentioned imidazole, but also its acid addition salt, picrate (C 3 H 4 N 2・C 6 H 3 N 3 O 7 ) or benzoate (C 3 H 4 N 2・C 7 H 6 O 2 ), and the dyeing treatment is not limited to dipping treatment in dyeing bath 2, but may also be a printing treatment. .

どることとなる。 In this way, since the material veneer 1 is dyed in the dyeing bath 2 containing imidazole or its acid addition salt, which is effective in preventing discoloration and fading, the woody part 5a of the artificial decorative veneer 5 obtained is expressed. In the inside of the material veneer 1 where the degree of penetration of the dye is small, the penetration of the imidazole (or its acid addition salt) is also small, and on the contrary, in the surface layer of the material veneer 1 where the annual ring part 5b is expressed, the penetration of the dye is significant and at the same time. The imidazole (or its acid addition salt) has also sufficiently penetrated, and the aging of the artificially decorated veneer 5 shows that the annual rings 5b, where the imidazole has sufficiently penetrated, have little discoloration, and the woody regions 5a, where the imidazole has insufficiently penetrated, have little discoloration. The discoloration becomes more severe, and the process of discoloration closely resembles that of natural wood.

粧単板とすることができる。 As described above, the method for producing artificially decorated veneers of the present invention includes a dyeing process of dyeing a material veneer with a dyeing solution of an acid dye containing imidazole or its acid addition salt, and a dyeing process of dyeing a plurality of veneers subjected to the dyeing process. The method includes a composite fritch forming process in which material veneers are laminated and pressure-bonded via an adhesive to obtain a composite frit; and a slicing process in which the composite frit is sliced in a direction intersecting the laminated surface. Among the wood grain patterns expressed on the surface of decorative veneers, imidazole (or its acid addition salts), which has a high effect of preventing discoloration and fading, penetrates into the annual rings, while imidazole (or its acid addition salts) has a high penetration rate in the woody parts. Penetration is small, and the discoloration of the woody part becomes more pronounced than that of the annual rings due to aging, making it possible to create an artificially decorated veneer with a rich natural feel, following a discoloration process that closely resembles that of natural wood.
