Abstract

PURPOSE: Sheets of base material to which lignin is added are impregnated with a phenolic resin to provide a prepreg and another prepreg of melamine resin is laminated with the resulting prepreg to produce said decorative sheets of melamine resin with good flexibility without any adverse effects on resistance to weathering and water.
CONSTITUTION: A prepreg is prepared by impregnating sheets of base material to which lignin is added with a phenolic resin varnish resulting from the reaction between 1 mole of a phenol compound, as phenol, and 1.3 W 1.8 mole of formaldehyde in the presence of an alkali catalyst with 7.8 W 9.5 pH under refluxing for 30 W 90 min. The resulting prepreg is laminated with another prepreg of melamine resin and formed under pressure of 100 kg/cm2 with heat at 130 W 180°C to form said melamine resin decorative sheet. The sheets of base material are, e.g., those of kraft paper, cloth, nonwoven fabrics, and others.
