Outdoor exposure was carried out on a test table of °, and the condition was observed and the color difference was evaluated every 6 months. The color difference was measured by a color difference meter (CR-310, manufactured by Minolta). In the table, “ΔE” represents the difference between the color before the start of the test and the color after the start of the test when the lightness is L and the chromaticity is numerically represented by a and b with respect to the color of the coated surface. ★ Evaluation criteria for condition observation ・ Mold ◎: No contamination by mold is observed. A: Almost no mold contamination is observed. Δ: Mold contamination is partially observed. X: The mold is severely contaminated.・ Painted surface ◎: Discoloration of the painted surface is difficult to see. ◯: The painted surface is slightly brown. Δ: The coated surface is brown. X: The painted surface is grayed.

Further, Comparative Example 3, which is the invention disclosed in Japanese Patent Application Laid-Open No. 10-203902, has an effect that is not much different from that of the present invention in terms of mold and coated surface, but the transmittance is extremely low at 0.3, and grain and It is extremely difficult to take advantage of the skin texture. On the other hand, in the examples, it is possible to prevent mold and deterioration of the coated surface for a long period of time, and it is possible to secure a practically sufficient transmittance.

After coating and air-drying for 20 days, it was immersed in still water for 30 seconds, then placed in a desiccator with water on the bottom and left in a thermostat at 26 ° C. for 4 hours. Then, add 2 to the 40 ° C incubator.
After the operation of standing for 0 hour was repeated 10 times, the weight (previous weight) of the treated sapwood was measured. Next, add the treated sapwood, 150 termite feeding ants and 15 soldier ants into the container,
Weight of treated sapwood after rearing for 1 day (rear weight)
Was measured, and the mass reduction rate (%) was calculated from the difference between the front weight and the rear weight. As a comparative control, untreated red pine sapwood was subjected to the same test. ★ Evaluation criteria Evaluation was made by the mass reduction rate.
