摘　　要：The study illustrates differences between colors of poplar I-214 veneers dyed by reactive blue KN-R and 4 kinds of chemical reagents, and those of treated veneer exposed to UV-ray for 3 days. The results show there are some laws in poplar I-214 dyeing and UV-ray attenuation of each chemically treated veneer color. The chemical reaction carded out between cellulose or lignin on veneer surface and dye molecules when they met with. The capability of dyeing and discoloration of veneer is improved by control of dyeing technology, especially chemical treatments; being treated by acetylation and maleic anhydride protects dyed wood discoloration.The study illustrates differences between colors of poplar I-214 veneers dyed by reactive blue KN-R and 4 kinds of chemical reagents, and those of treated veneer exposed to UV-ray for 3 days.
