Abstract

A compound (A) of the present invention is represented by the formula (1): wherein each R 1 independently represents a group represented by the formula (2) or a hydrogen atom, and each R 2 independently represents a hydrogen atom or a linear or branched alkyl group having 1 to 6 carbon atoms, provided that at least one R 1 is a group represented by the formula (2); and wherein -* represents a bonding hand.

Claims (32)

1. A compound represented by the following formula (17):

2. A method for producing the compound according to claim 1 , comprising a step of reacting an alcohol compound represented by the following formula (4)

with an acid anhydride represented by the following formula (6):
