The present invention provides a polyhydric phenol compound which has an excellent alkali resistance and which does not cause a deterioration in color even when used as a resin raw material or a color developer. The polyhydric phenol compound includes: a bisphenol compound (A) represented by the following Formula (1) and a trisphenol compound (B) represented by the following Formula (2):
[wherein R1 represents a monovalent aliphatic hydrocarbon group having from 6 to 24 carbon atoms; each of R2, R3, R4, R5 and R6 represents a monovalent hydrocarbon group having from 1 to 15 carbon atoms; and each of a, b, c, d and e represents an integer from 0 to 4] ;
wherein the trisphenol compound (B) is contained in an amount, in terms of absorption intensity ratio at 254 nm, of less than 1.6% by area with respect to the amount of the bisphenol compound (A).
本发明提供了一种多羟基酚化合物,它具有优异的耐碱性,即使用作树脂原料或显 色剂也不会导致颜色变差。该多羟基酚化合物包括:由下式(1)表示的双酚化合物(A)和由下式(2)表示的三酚化合物(B):
[其中 R1 代表具有 6 至 24 个碳原子的单价脂族烃基;R2、R3、R4、R5 和 R6 各代表具有 1 至 15 个碳原子的单价烃基;a、b、c、d 和 e 各代表 0 至 4 的整数] ;
其中三苯酚化合物(B)的含量(以 254 纳米波长处的吸收强度比计)小于双苯酚化合物(A)含量的 1.6%(以面积计)。
