  • Patent number: 8536283
    Abstract: A varnish composition includes (1) a benzoxazine resin having highly symmetric molecular structure; (2) at least one of naphthol novolac resins, aniline novolac resins and phenolic novolac resins; (3) fillers. The benzoxazine resin having highly symmetric molecular structure, and the at least one of naphthol novolac resins, aniline novolac resins and phenolic novolac resins contribute to increase the glass transition temperature of the varnish composition, while decrease the coefficient of thermal expansion and moisture absorbability due to their small and highly symmetric molecular structures. A copper substrate can meet the requirement of high glass transition temperature (TMA?200° C.) and low coefficient of thermal expansion (?1/??30/135 (?m/m° C.). Therefore, the composition of the invention can be widely used as high-performance electronic material.
