Abstract
PURPOSE: The titled material, usable by polymerizing a reaction product between an oxyalkyl di(meth)acrylate as a polymerizable monomer and an organic diisocyanate solely or as one component, and capable of giving a cured article having improved strength characteristics.
CONSTITUTION: A dental filling material usable by polymerizing a reaction product between 2mol oxyalkyl diacrylate or oxyalkyl dimethacrylate as a polymerizable monomer and one mole organic diisocyanate, e.g. diurethane tetraacrylate or diurethane tetramethacrylate of the formula (R1, R2, R3 and R4 are H, or methyl; (n) is 2W10), preferably the compound of the formula in which R1WR4 are methyl respectively and (n) is 6, solely or as one component. The hardness, compressive strength, bending strength, tensile strength, etc. are improved, and the cured article made from the material has a color tone close to that of the dentine. There is almost no difference in color tone between the dentine and the filled site.
