The present invention relates to a cationic coating formulation, which contains beside water a specific anionic ultrafine ground calcium carbonate, a non-ionic polyvinyl alcohol, a water-soluble salt of a divalent metal ion, a dispersing agent and a cationic polymer. Said coating formulation according to the present invention can be used for manufacturing a digital print medium, preferably an inkjet print medium.

Coating formulation for a digital print medium

The present invention refers to a paper article comprising a paper component having a first side and a second side, wherein the first side and/or the second side of the paper component is at least partially coated with a heat-sealable coating, wherein the heat-sealable coating comprises a first polymer comprising units derived from a (meth)acrylate and/or (meth)acrylic acid and/or a salt thereof, and a second polymer, being different from the first polymer, comprising units derived from a) a (meth)acrylate and/or (meth)acrylic acid and/or a salt thereof, and b) an alkene, wherein the first polymer and the second polymer are present in the heat-sealable coating in a weight ratio of 90:10 to 35:65, and wherein the first polymer and the second polymer are present in the heat-sealable coating in an overall amount of at least 50 wt. %, based on the total weight of the coating. Furthermore, the present invention refers to a laminate comprising a paper component, a substrate and a heat-seal layer being present between the paper component and the substrate, which is obtained by heat-sealing a paper article according to the present invention to the substrate. The invention also refers to a use of a coating for heat-sealing a paper component to a substrate.

Paper article comprising a paper component and a heat-sealable coating

The present invention relates to a coating formulation for digital printing media comprising a polymeric binder and a solid metal complex, wherein said solid metal complex comprises (i) a divalent or trivalent metal cation and (ii) a polydentate ligand. The invention further relates to a method for preparing the inventive coating formulation, to a digital printing medium comprising the inventive coating and a method for preparing same, and to corresponding uses.

Coating formulation for digital printing media

The present invention relates to the field of rotogravure printing, and more specifically to a rotogravure printing medium, a coating composition for rotogravure printing media, a method for producing such a rotogravure printing medium and an use of the rotogravure printing medium in a printing application, preferably in rotogravure printing using electrostatic assist (ESA).

Calcium carbonate for rotogravure printing medium

The present invention relates to a process for the manufacturing of a calcium carbonate-comprising material, a calcium carbonate-comprising material obtained by a process as well as the use of the calcium carbonate-comprising material for paper filler and paper coating applications, cigarette paper applications, for plastics applications or in paints, coatings, adhesives, replacement of titanium dioxide, preferably in paints, sealants, food, feed, pharma, concrete, cement, cosmetic, water treatment and/or agriculture applications.

Process to obtain an ultrafine GCC with high light scattering properties and high solid content

The present invention concerns a print medium and a method of producing such a print medium. In particular, the present invention is directed to a print medium comprising a substrate having a first and a reverse side, and at least one coating layer on of the substrate sides.
