NOVELTY - A fluorenone compound (I) is reacted with thiol and alcohol (II) in the presence of an acidic catalyst, and alcohol having fluorenone structure (III) is manufactured. The usage amount of alcohol (II) is 3 mol or more with respect to 1 mol of fluorenone. The usage amount of thiol is 3 parts weight or more with respect to 100 parts weight of fluorenone.    USE - Manufacture of alcohol having fluorenone structure for resin (claimed). Uses include but are not limited to resin hardening agent, semiconductor sealing agent, antireflective film, optical waveguide, eyeglass lens, resin filler, adhesive agent, thermosensitive recording material, organic photoreceptor, solar cell, color filter, sensor, sliding component, digital paper, motor vehicle components, aeronautical navigation and hologram.    ADVANTAGE - The alcohol having fluorenone structure is efficiently manufactured without generating coloring. The residual amount of unreacted fluorenone is reduced. The alcohol has improved optical characteristics, heat resistance, water resistance, moisture resistance, chemical resistance, electrical property, mechanical characteristics and dimensional stability.    DETAILED DESCRIPTION - A fluorenone compound of formula (I) is reacted with thiol and alcohol of formula (II) in the presence of an acidic catalyst, and alcohol having fluorenone structure of formula (III) is manufactured. The usage amount of alcohol (II) is 3 mol or more with respect to 1 mol of fluorenone. The usage amount of thiol is 3 parts weight or more with respect to 100 parts weight of fluorenone.    R1,R3=substituent;    k=0-4;    Z=aromatic hydrocarbon ring;    R2=alkylene;    m,n=1 or more;and    p=0 or more.    When ring (Z) is benzene ring, n is 1. INDEPENDENT CLAIMS are included for the following:    (1) alcohol having fluorenone structure; and    (2) resin containing the alcohol having fluorenone structure as polymerization component, and chosen from ester resin, poly(meth)acrylate resin and epoxy resin.
