かつた。 It has been pointed out that so-called laminated decorative veneers have the disadvantage of discoloration when exposed to sunlight. This is because the wood veneer fabric discolors due to UV rays. Conventionally,
Including laminated decorative veneer or veneer decorative veneer, etc.
Methods for preventing discoloration of so-called decorative veneers due to ultraviolet rays and the like include applying an ultraviolet absorber to the decorative veneer and applying polyethylene glycol to the decorative veneer. However, with these methods, sufficient effects could not be obtained when the whiteness of the decorative veneer became large.

The process is characterized by preparing a treatment agent by dispersing it at 5wt%, impregnating the decorative veneer with the treatment agent, and then drying it. Here, the term "white or colorless inorganic pigment" has a broader meaning than usual, and includes all white or colorless inorganic fine particles that have the property of blocking ultraviolet rays. For example, titanium oxide, barium sulfate, alumina, etc. Also,
The reason why the inorganic pigment is white or colorless is to hide the color of the decorative veneer of the fabric as much as possible.
Vehicle means a color vehicle, such as water, solvent,
It refers to a liquid component other than a pigment, such as a resin or an emulsion of a resin, and any component that can disperse the pigment may be used, even if it is simply removed by drying with water or a solvent. However, it is particularly preferred that curable resins be used. As the curable resin, for example, a curable acrylic resin is preferable. Note that the decorative veneer means a laminated decorative veneer, a veneer decorative veneer, or the like.

る。また、顔料の分散量を10±5wt％とするた
め、化粧単板に含浸させた後も単板の表面の木質
感が失われることもないのである。 When a decorative veneer is impregnated with the above treatment agent by immersing it, the pigment with a small particle size penetrates into the decorative veneer and becomes fixed, improving weather resistance. When such a treatment is applied, the pigment penetrates into the decorative veneer, so even if the surface of the veneer is sanded, the effect of preventing discoloration will not be lost. Furthermore, since the amount of pigment dispersed is 10±5wt%, the woody feel of the surface of the veneer will not be lost even after it is impregnated into the decorative veneer.

る。 In addition, if a vehicle containing a curable resin is used, the resin blended in the vehicle will harden and further fix the pigment, and the resin will harden and be fixed to the wood, so the wood will be hardened. Since it is shielded from the air and prevents discoloration caused by air, discoloration of the veneer can be more reliably prevented.

使用することもできる。 This invention is put to practical use as a method for preventing discoloration of general veneers, but is particularly effective as a method for improving the weather resistance of laminated decorative veneers. Regarding prevention of discoloration, it is sufficient that at least the above pigment is blended in the vehicle within the above range, and the vehicle may be simply a liquid component such as water or a solvent, and if necessary, a curable resin may be blended. Instead, plastic resins and waxes can also be used.
以下、実施例に基づいて説明する。 The following will explain based on examples.

(including dispersion medium), commercially available titanium oxide pigment (particle size 2-3μ) in a vehicle consisting of 85wt% water.
A white processing agent was prepared by dispersing 5wt%.
(2) 比較的白度の大きいパイン調の集成化粧単板
（CIE1976で定義するＬ＊≧80）を前記の白色
処理剤に浸し、含浸量が170〜180ｇ／m2（wet
基準）となるようにした。(2) A pine-like laminated decorative veneer with relatively high whiteness (L*≧80 as defined by CIE1976) is soaked in the above-mentioned whitening agent, and the amount of impregnation is 170 to 180 g/m 2 (wet
standard).
(3) 前記含浸単板を乾燥した。(3) The impregnated veneer was dried.
(4) 得られた単板の、半分をビニルテープで被覆
してフエードメータに入れ、48時間紫外線を照
射し、その後変色部と非変色部（被覆部）の色
調を測定した。(4) Half of the obtained veneer was covered with vinyl tape, placed in a fade meter, and irradiated with ultraviolet rays for 48 hours, after which the color tone of the discolored area and non-discolored area (covered area) was measured.
(5) 変色部と非変色部の色差ΔＥ（国際照明委員
会（CIE）1976年法による）で耐候性を評価し
た。(5) Weather resistance was evaluated based on the color difference ΔE between the discolored area and the non-discolored area (according to the 1976 law of the Commission Internationale de l'Eclairage (CIE)).
以上の手順でΔＥを測定し、その結果を無処理
の化粧単板について行つた同様の耐候性試験結果
のΔＥと比較すると以下のようであつた。 The ΔE was measured according to the above procedure, and the results were compared with the ΔE of a similar weather resistance test conducted on an untreated decorative veneer, and the results were as follows.
処理単板ΔＥ＝11.08（σ＝1.20）
無処理単板ΔＥ＝15.95（σ＝0.05）
（何れも繰り返し４回測定、σは標準偏差）
上記結果より明らかに処理の効果が表れている
ことがわかる。 Treated veneer ΔE = 11.08 (σ = 1.20) Untreated veneer ΔE = 15.95 (σ = 0.05) (All measurements were repeated 4 times, σ is the standard deviation) The above results clearly show the effect of the treatment. Recognize.
つぎに処理単板の表面をサンデング処理して前
記手順(4)、(5)を行つた。 Next, the surface of the treated veneer was subjected to sanding treatment, and the above steps (4) and (5) were performed.
サンデング処理後の処理単板のΔＥは11.20
（σ＝2.09）であり、サンデングを行つても効果
が失われることがないことがわかる。 ΔE of treated veneer after sanding treatment is 11.20
(σ=2.09), and it can be seen that the effect is not lost even if sanding is performed.
実施例 ２
実施例１の手順(1)のアクリルエマルジヨンの代
わりに、ワツクスエマルジヨンを使用しても同様
な効果が確認できた。Example 2 Similar effects were confirmed when a wax emulsion was used in place of the acrylic emulsion in step (1) of Example 1.

以上の結果を総括すると、比較的白度の大きい
化粧単板でも（CIE1976で定義するＬ＊≧80で
も）紫外線による変色度合が、従来の60〜70％程
度に押さえられることがわかつた。 Summarizing the above results, it was found that the degree of discoloration caused by ultraviolet rays can be suppressed to about 60 to 70% of the conventional level even for decorative veneers with relatively high whiteness (even when L*≧80 as defined by CIE 1976).
