Abstract:
A coating composition for a corrugated paper board is described. The corrugated paper board includes an inner liner sheet and an outer liner sheet adhered to opposite sides of a corrugated medium. The coating composition includes a pre-coat layer and a topcoat layer. The pre-coat layer includes an ink fixer agent and a pigment, and is disposed on one or both of the liner sheets. The topcoat layer is disposed on top of the pre-coat layer to form an ink receiving layer. The topcoat layer includes a wax and is devoid of the ink fixer agent.
