| abstract |
High yield resin saturable papers containing total lignin, based on paper weight, in amounts from about 8 up to 15 percent are employed as core stock for high pressure decorative melamine laminates. At least 65 percent of the fibers should be hardwood fibers. Up to 35 percent of softwood fibers may be present but then the softwood lignin, based on paper weight, should not be greater than about 2.8 percent. |
