Document Type and Number:
WIPO Patent Application WO/2022/075225
Kind Code:
A1
Abstract:
A purpose of the present invention is to provide a coating composition having superior compatibility with DPM and superior drying characteristics, and a polycarbonate polyol composition with which it is possible to form a coating film and/or a polyurethane film having superior durability. A polycarbonate polyol composition that includes: an unmodified polycarbonate polyol containing the carbonate structure shown in formula (A); and a modified polycarbonate polyol containing the carbonate structure shown in formula (A) and the urethane structure shown in formula (B), 90 mol% or more of the total terminal groups of all compounds in the composition being hydroxyl groups, and the number of functional groups calculated using formula (II) being 2.00-10.00. Number of functional groups = Mn × OHV/56.11/1000 (II)
