The present invention includes a label, a label sheet and a method for manufacturing the label. The label includes a paper facestock having first and second surfaces and a layer of pressure sensitive adhesive proximal to the second surface. The label can be adhered to a substrate having pre-applied indicia to cover the indicia and the label is opaque enough to prevent the viewing of the covered indicia while matching the color of the substrate.

The invention relates to a surface treatment composition for paper, board or other fibrous webs. The composition of the invention comprises particles which comprise an active material and a supporting material. The active material comprises a salt or a multivalent metal, such as a divalent or trivalent metal. In accordance with the invention, the supporting material is adapted to release the active material from the particles when subjected to heat and/or pressure and/or a change in pH. Consequently, the active material's adverse effects on the rheology of the composition are avoided while its desired effects on the surface characteristics are retained or enhanced.

A coated paperboard comprising a paperboard substrate having a first side and a second side and a coating in contact with the first side of the paperboard substrate, the coating including binder and pigment, the coating containing substantially no fluorochemical or wax, wherein the coated paperboard has a 3M kit test value of at least 3, and wherein the coated paperboard is repulpable.

The present disclosure is drawn to a recording medium including a substrate, a first coating applied to the substrate, and a second coating applied to the first coating. The first coating can include inorganic pigment, fixative agent, and a first binder. The second coating can include inorganic nanoparticles, aluminum silicate, and a second binder.

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.
