Abstract
Through use of this water-/oil-repellent agent including a modified heterocyclic compound having a heterocycle and a C1-40 hydrocarbon group, adequate oil-resistance can be imparted to a substrate. The heterocycle is preferably a nitrogen-containing heterocycle. The hydrocarbon group is preferably an octyl group, a decyl group, an undecyl group, a lauryl group, a tridecyl group, a myristyl group, a palmityl group, a cetyl group, an isopalmityl group, a stearyl group, or a behenyl group. The heterocycle is preferably pyrimidine, pyridazine, pyridine, diazine, triazine, oxazole, or oxadiazole.
Claims15
