PROBLEM TO BE SOLVED: To obtain a decorative melamine laminate which has a milky white core layer and is hardly warped and does not develop a base material color tone ton a decorative layer even if bonded to the base material such as plywood, a particle board or a steel plate, and is excellent in water resistance.SOLUTION: A decorative laminate uses resin impregnated core paper which is formed by impregnating core paper with a resin liquid composed primarily of a condensate of an amino compound and formaldehyde and drying it. In this case, melamine and guanamine is used as an amino compound. A molar ratio of them is 1:0.3-1.5 mol. In addition, the resin liquid is combined with a denaturating agent comprising (A) divalent polyalkylene glycol or a derivative thereof, and (B) tri- or higher valent polyalkylene glycol multi-valent ether. |
