Claims3
A substituted trisphenol compound represented by formula (3):
- wherein R1's each independently represent a linear, branched, or cyclic alkyl group having 1 to 6 carbon atoms or a phenyl group, R3's and R4's each independently represent a linear, branched, or cyclic alkyl group having 1 to 6 carbon atoms or an aryl group having 6 to 8 carbon atoms, R3 and R4 are optionally bonded to each other to together form a cyclic secondary amino group optionally containing an oxygen atom or a sulfur atom and having 5 to 10 carbon atoms, n represents an integer of 1 or 2, m represents 0 or an integer of 1 to 3, and p represents an integer of 1 to 6, provided that m+n is an integer of 1 to 4.
A substituted trisphenol compound represented by formula (4):
- wherein R1's each independently represent a linear, branched, or cyclic alkyl group having 1 to 6 carbon atoms or a phenyl group, R5's each independently represent a linear, branched, or cyclic alkyl group having 1 to 6 carbon atoms or an aryl group having 6 to 8 carbon atoms, n represents an integer of 1 or 2, m represents 0 or an integer of 1 to 3, and p represents an integer of 1 to 6, provided that m+n is an integer of 1 to 4.
A substituted trisphenol compound represented by any of the following formulae:
