PURPOSE: To produce a printing sheet having proper stiffness, enhanced in printing workability, having high strength and excellent in concealability, surface strength and printability.
CONSTITUTION: A printing sheet is constituted by accumulating a large number of continuous filaments and an undercoating layer is provided to the single surface of a nonwoven fabric with a basis wt. of 20-150g/m2 and, further, a topcoating layer constituted of white pigment and an adhesive is provided on the surface of the undercoating layer. The undercoating layer is provided by applying foamed paint to the nonwoven fabric. The air permeability due to JISL1079 of the nonwoven fabric provided with the undercoating layer is set to 5-40m/cm2/sec when the air permeability thereof before the undercoating layer is provided is 80-200m/cm2/sec and adjusted to 5-50% of that of the nonwoven fabric when the air permeability thereof before the undercoating layer is below 80ml/cm2/sec and, thereafter, the topcoating layer is provided on the undercoating layer. By this constitution, this printing sheet can be suitably used as a material for a packing material, a bag article or a poster.
