Title:
RESIN COMPOSITIONS
Document Type and Number:
Japanese Patent JP2015004009
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide resin compositions which impart flame retardance to cured products of the resin compositions and allow preparation of cured products that can achieve low linear thermal expansion coefficients, low dielectric loss tangents and high glass transition temperatures.SOLUTION: A resin composition contains (A) a flame retardant having one or more vinyl groups or styryl groups and a phosphaphenanthrene skeleton in each molecule, (B) a radical-polymerizable resin having one or more functional groups selected from among a vinyl group, a styryl group, an allyl group and an acrylic group in each molecule, and (C) an inorganic filler. When the resin content in the resin composition excluding the inorganic filler is regarded as 100 mass%, the phosphorus content is 0.2 to 5 mass%.
