Abstract
A compound having an uretonimine group contains, as a structural unit, a carbodiimide compound derived from at least one of an aliphatic diisocyanate and an aromatic diisocyanate, and also contains an isocyanate compound as a structural unit, wherein the residue obtained by removing an isocyanate group from the isocyanate compound and the residue obtained by removing a carbodiimide group from the carbodiimide compound are different.
Claims18
A compound having an uretonimine group, the compound of general formula (1α):
- wherein in general formula (1α), n11 is an integer of at least 1 but not more than 100, each of X11 and X12 is independently a residue obtained by removing a hydrogen atom from a terminal hydroxyl group of a monofunctional polyalkylene oxide polyether alcohol, Q11 is a group of general formula (1-a) shown below or a group of general formula (1-b) shown below, when n11 is 1, Q11 is a group of general formula (1-b) shown below, and when n11 is 2 or greater, plural Q11 may be identical to or different from each other, and each of R11 and R12 is independently a residue obtained by removing two isocyanate groups from a diisocyanate,
- wherein in the formulas, each asterisk indicates a bonding site, in general formula (1-b), Y11 is a residue obtained by removing one isocyanate group from an isocyanate compound, and the diisocyanate and the isocyanate compound are different compounds.
