PROBLEM TO BE SOLVED: To provide a decorative board without using formaldehyde. SOLUTION: The resin composition is obtained by compounding a vinyl acetate-based polymer with a molecular weight of 2,000-100,000 and a crosslinking agent having more than one allyl groups in the molecule and an organic peroxide. The compounding ratio is 5-100 pts.wt. of the crosslinking agent, 0.1-10 pts.wt. of the organic peroxide to 100 pts.wt. of the vinyl acetate-based polymer. The crosslinking agent is obtained by the addition reaction of a compound having more than one isocyanate groups and an allyl alcohol. The decorative board is obtained by impregnating paper for decorative boards with the resin composition, drying the paper and molding the paper by heat-press molding. COPYRIGHT: (C)2005,JPO&NCIPI
