    • PROBLEM TO BE SOLVED: To solve such problems that:(1) a volume ratio of a resin composition is decreased to decrease the fluidity of the composition, which thereby degrades viscosity of a prepreg obtained by impregnating a base material such as glass cloth with the resin composition and half-curing the material; (2) a metal foil-clad laminate obtained by laminating and curing the above prepreg with a metal foil has low moldability such as inducing cracks or voids; and (3) the metal foil-clad laminate shows degradation in moisture absorption heat resistance, an elastic modulus, and adhesive strength between a copper foil and an insulating layer of the laminate.SOLUTION: A resin composition is provided, comprising an epoxy resin (A) expressed by formula (1), a phenol resin (B), a maleimide compound (C) and an inorganic filler (D), in which the content of the inorganic filler (D) in the resin composition is 50 to 600 pts.mass with respect to total 100 pts.mass of the components (A) to (C).
    • 要解决的问题:为了解决以下问题:(1)降低树脂组合物的体积比以降低组合物的流动性,从而降低通过浸渍诸如玻璃布的基材获得的预浸料坯的粘度, 树脂组合物和半固化材料; (2)通过用金属箔层压和固化上述预浸料获得的覆金属箔层压板具有低的成型性,例如引起裂纹或空隙; (3)覆盖有金属箔的层叠体,在层叠体的铜箔与绝缘层之间的吸湿耐热性,弹性模量和粘合强度降低。提供了一种树脂组合物,其包含环氧树脂( A),树脂组合物中无机填充剂(D)的含量为50〜600重量份的酚醛树脂(B),马来酰亚胺化合物(C)和无机填料(D) 相对于总成本(A)至(C)的总共100点数。
