CONDENSATE BETWEEN RESORCIN AND ACETONE

WIPO Patent Application WO/2018/051999

A1

The present invention provides a condensate between resorcin and acetone, wherein, as analyzed by gel permeation chromatography, the proportion of the area of a peak (1) representing a weight-average molecular weight of not less than 160 but less than 480 is 70% or less, the proportion of the area of a peak (2) representing a weight-average molecular weight of not less than 480 but less than 600 is 25-50%, and the sum of the proportion of the area of a peak (3) representing a weight-average molecular weight of not less than 600 but less than 800 and the proportion of the area of a peak (4) representing a weight-average molecular weight of not less than 800 is 26% or less, with respect to the total area of the peaks representing a weight-average molecular weight of 160 or more.
