From the view of amphiphilic structure of urushiol molecules as main components in lacquer tree paint, the effect of addition of amphiphilic compounds to the lacquer tree paint on the curing process and the light resistance was investigated to find the relationship between the curing reaction of lacquer tree paint and the molecular structures of the amphiphiles as additives. Lacquer tree paint films were added amphiphiles such as 2-hydroxy-4-alkoxybenzophenone bearing alkyl group with different chain lengths, poly(oxyethylene) octadecyl ether with different oxyethylene unit numbers, suger ester and light stabilizer having long alkyl groups, cured and photo-irradiated.When the chain length of alkyl groups in the benzophenone derivatives is close to that in urushiol molecules, the curing reaction was little inhibited. Surfactants with larger poly(oxyethylene) units exhibited more profound inhibition of curing reaction. Amphiphiles used as additives in the present study were not observed to promote the formation of reverse micelles in lacquer tree paint, but they were compatible with the reverse micelle structure.
