- (wherein, R1 and R2 each independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms;
- R3, R4 and R5 each independently represent a hydrogen atom, a formyl group or an alkylcarbonyl group having 2 to 15 carbon atoms, but not all of them represent hydrogen atoms;
- A and B each independently represent an aryl group having 6 to 10 carbon atoms;
- R6 and R7 each independently represent a hydrogen atom, a halogen atom or an alkyl or alkoxy group having 1 to 6 carbon atoms;
- m and n each independently represent an integer of 0 or 1 or more, but are not 0 simultaneously;
- p and q are each independently 0 or an integer of 1 or 2).
