    Abstract: A process for the manufacture of a paper suitable for use in a laminated product is described. The process comprising: (a) impregnating the paper preferably on the paper machine with melamine resins dissolved in a solvent, the melamine resins being more than 80% water soluble; the solution having a solids content of less than 50% such that ink may be added to the paper following impregnation. Thus in contrast to established techniques, an ink-pattern is preferably added to the paper after the paper has been treated, preferably impregnated, with resin. In preferred embodiments the paper is calendered after addition of the resins in step (a). The paper can then be further impregnated after printing then combined with a substrate to form a laminated flooring product. Step (a) reduces the wet-expansion caused by the later addition of further resins and is especially useful when step (a) is performed before adding the ink-pattern which then also reduces wet expansion caused by the addition of ink.
