PROBLEM TO BE SOLVED: To provide a biobased cross-linked composition derived from organism, a method for producing the crosslinked composition, a structure prepared therefrom, a biobased printed wiring board using the above composition and a method for producing the above structure. SOLUTION: Biobased materials such as lignin, crop oils, wood resins, tannins, polysaccharides and combinations thereof are cross-linked, preferably using heat, a cross-linking agent, and an initiator. The materials fabricated have suitable characteristics for printed wiring boards. A glass fiber or biobased cloth is impregnated with an admixture of the biobased material cross-linking agent and initiator and the impregnated material is processed by conventional methods to produce a printed wiring board.
