  • Patent number: 10457762
    Abstract: The present invention relates to a diacrylate compound represented by general formula (1), a composition thereof, and a cured product of the compound/composition. In the formula, R denotes a hydrogen atom or a methyl group; R1, R2, R3, and R4 each independently denote a C1-6 linear or branched alkyl group, with the proviso that R1, R2, R3, and R4 are not all methyl groups. The present invention provides: a novel diacrylate compound which can provide a cured product having an excellent balance of physical properties such as low curing shrinkage, flexibility, resistance to bending, and low curling properties, and which can be used as a photo- or thermal-radical polymerizable monomer; a composition of the compound; and a cured product of the compound/composition.
