<p>An electric metal foil-plated laminate sheet which is obtained by laminating a cured layer of a thermosetting resin composition with electroconductive foils, said thermosetting resin composition comprising 30-85% by weight of (A) a rubber-modified vinyl ester obtained by reacting, (a) an epoxy resin, (b) a carboxyl group containing rubbery polymer derived from a conjugated diene, and (c) at least one unsaturated monocarboxylic acid selected from the group consisting of acrylic acid and methacrylic acid to react one another in amounts such that, based on 100 parts by weight of (a) the epoxy resin, (b) the carboxyl group containing rubbery polymer accounts for a proportion in the range of 5 to 80 parts by weight and that the total number of carboxylic group contained in (b) the rubbery polymer and (c) the unsaturated monocarboxylic acid falls in the range of 1.3 to 1.5 per each of the epoxy groups contained in (a) the epoxy resin at a temperature of 90 DEG to 120 DEG C., 5-30% weight of (B) a specific unsaturated polyester, and 10-60% by weight of (C) a radically polymerizable unsaturated monomer, wherein (A)+(B)+(C) equals 100% by weight.</p> |
