Following formula: (In the above formula, R is a group consisting of (i) a substituted or unsubstituted alkyl having both ends C = 0-12, (ii) a substituted or unsubstituted aryl, and (iii) a substituted and unsubstituted alkylaryl. Chosen by X ¹ , X ² , X ³ and X ⁴ are each selected from the group consisting of alkyl, aryl, alkylaryl groups and hydrogen, and R ¹ , R ² , R ³ and R ⁴ are alkyl, aryl, alkylaryl groups and hydrogen, respectively. Each of R ² and R ³ may be optionally bridged by a polymethylene group, and when R is C = 0, the combined groups R ¹ R ² are combined And R ¹ , R ² , R ³ and R ⁴ are each hydrogen in the case where R is the same as R ³ R ⁴ and C = 1 in R.
