Title: POLYVALENT PHENOL COMPOUND AND METHOD OF PRODUCING SAME
Abstract:
Provided is a polyvalent phenol compound that exhibits superior alkali resistance, without negatively affecting color, even when used as a resin feedstock material or developer. The polyvalent phenol compound contains less than 1.6 area%, in terms of 254 nm absorption intensity ratio, of a trisphenol compound (B) represented by the following formula (2) relative to a bisphenol compound (A) represented by the following formula (1) (wherein R1 is a monovalent aliphatic hydrocarbon radical comprising 6–24 carbon atoms; R2 and R3 are monovalent hydrocarbon radicals comprising 1–15 carbon atoms; and a and b are integers from 0 to 4) (wherein R1 is as defined in formula (1); R4, R5, and R6 are monovalent hydrocarbon radicals comprising 1–15 carbon atoms; and c, d, and e are integers from 0 to 4).
