Abstract

See full text

A coating structure for a sheet-like substrate is disclosed including cellulosic fibres and a sheet-like product. The structure includes at least one pre-coat layer and a top coat layer, where the pre-coat layer(s) and the top coat layer include 10-90 weight-% of a styrene (meth)acrylate copolymer which is polymerised in the presence of a stabiliser, and which has a glass transition temperature Tg≤20° C., preferably ≤15° C., more preferably ≤13° C. Furthermore, the pre-coat layer(s) includes a polysaccharide, such as starch, and the top coat layer includes 5-60 weight-% of at least one water-soluble coating binder, which is selected from polysaccharides and polyvinyl alcohols, as well as at most 5.0 weight-% of a cross-linker, which reacts with —OH or —COOH groups.
