(57) [Summary] [Structure] Obtained by subjecting a polyhydric alcohol and a derivative of (meth) acrylic acid and / or a (meth) acrylic ester to an esterification reaction in an organic solvent in the presence of an acid catalyst. The reaction product is neutralized and then further treated with amines to produce a polyfunctional (meth) acrylate. [Effect] It is possible to provide a polyfunctional (meth) acrylate in which the residual catalyst in the reaction product is significantly reduced. The polyfunctional (meth) acrylate thus obtained can be used as it is in various conventionally known applications. For example, when it is used as a reactive diluent, it is not only excellent in quick-curing property and high hardness, but also has no problems of colorability, storage stability, mutagenicity, etc. Produce an effect. |
