Also disclosed is a fiber structure including fibers dyed with a dye containing a blue cationic dye having an azo bond, or a leather-like sheet including the fiber structure and an elastic polymer applied into internal voids of the fiber structure, wherein the leather-like sheet has a color difference (E) before and after a moist heat treatment, determined when subjected to the moist heat treatment at 80 C. and a humidity of 90% for 48 hours, of E2.

The present invention relates to a method for preparing a benzoxazine-containing resin composition and a prepreg and a laminate made therefrom. The method for preparing a benzoxazine-containing resin composition is adding an acidic filler to a benzoxazine-containing resin composition. By adding an acidic filler to the benzoxazine-containing resin composition, the present invention promotes greatly the polymerization reaction of benzoxazine and epoxy resin, reduces the curing temperature required for polymerization of benzoxazine and epoxy resin. The laminate prepared from the benzoxazine-containing resin composition, to which an acidic filler is added, has high anti-stripping stability, high glass transition temperature, low water absorption, high heat resistance, high bending strength and good processability, and can achieve low coefficient of thermal expansion.
