In the formula, R1 or R2 is preferably an aliphat. acyl amino group or arom. acyl amino group when R1 or R2 denotes an acyl amino group. R1 or R2 is 1-32C, more preferably 1-16C when the same is the aliphat. acyl amino group, and may be either of a chain or ring, straight chain or branched, satd. or unsatd. or substd. or unsubtd. The more preferable example of the substituent includes a halogen atom, aryl oxy group, etc. R1 or R2 is, preferably the substd. or unsubstd. phenyl group of 6-10C when the same is the arom. acyl amino group and the preferable example of the substituent is a halogen atom, etc. |
