COATING STRUCTURE, SHEET-LIKE PRODUCT AND ITS USE
The present invention relates to a coating structure for a sheet-like substrate comprising cellulosic fibres. The coating structure comprises at least a first coating layer and a second coating layer, where the second coating layer is arranged in a direct contact with the first coating layer. At least the first coating layer or the second coating layer is a barrier coating layer comprising at least one water-soluble cellulose derivative selected from alkyl celluloses, hydroxyalkyl alkyl celluloses, hydroxyalkyl celluloses and any of their mixtures, and a plasticizer.

Coating composition
An example of a coating composition includes an inorganic pigment, a latex, a cationic fixing agent, and a stabilizer selected from the group consisting of ethopropoxylated polyarylphenol, ethoxylated tristyrylphenol, modified fatty alcohol polyglycol ethers, and combinations thereof. Another example of a coating composition consists essentially of an inorganic pigment, a latex, a cationic fixing agent, a stabilizer selected from the group consisting of ethopropoxylated polyarylphenol, ethoxylated tristyrylphenol, modified fatty alcohol polyglycol ethers, and combinations thereof, and water.
Saccharide fatty acid ester inorganic particle combinations
The present disclosure describes methods of treating cellulosic materials with compositions that allow greater retention of inorganic particles on cellulosic substrates. The methods as disclosed provide combining saccharide fatty acid esters (SFAE) with such inorganic particles and applying such combinations on cellulosic materials to eliminate or reduce the use of retention aids or binders for filler in the paper making process. Compositions comprising such combinations of SFAE and inorganic particles are also disclosed.
