Document Type and Number:
WIPO Patent Application WO/2020/166646
Kind Code:
A1
Abstract:
A raw material composition for polyisocyanurates that includes a polyfunctional isocyanate, a compound (I) that is represented by formula (I), and an epoxy compound. In formula (I), R1 and R2 represent hydrogen atoms. R3–R5 each independently represent a hydrogen atom, a C1–10 alkoxy group, an amino group, a C1–10 monoalkyl amino group, or a C2–20 dialkyl amino group. Each of the three R3s–R5s may be the same or different. However, at least one of each of the three R3s–R5s is an amino group, a C1–10 monoalkyl amino group, or a C2–20 dialkyl amino group.
