摘要： A thermosetting resin composition comprising (A) a dibasic acid modified epoxy (meth)acrylate resin obtained by reacting a bromine-containing epoxy resin with a dibasic acid of 4 or more carbon atoms followed by further reacting with acrylic acid or methacrylic acid, (B) a thermosetting resin having an unsaturated group in its side chains, the unsaturated group being copolymerizable with the resin (A), and (C) a polymerizable monomer; and an electrical laminate produced by using the thermosetting resin composition are disclosed.
The electrical laminate excels in heat resistance, moisture resistance, and electrical properties and, as well, has a good punching quality.

摘要： A resin composition for cement which comprises a polymer obtained by emulsion polymerization of a dicyclopentadiene derivative represented by formula (I). An unsaturated epoxy ester, an alpha , beta -unsaturated carboxylic acid and an ethylenically unsaturated monomer copolymerizable with these three components is disclosed. The use of the composition by mixing with cement is also disclosed.
