Abstract: A coating composition for producing a layer composite, including a) a modified or unmodified polyvinyl alcohol, b) an alkylene/(meth)acrylic acid copolymer, c) a crosslinker, and d) one, two or more than two, pigments. The layer composite is used as food packaging, entry ticket, gaming ticket, car park ticket, or the like. A mixture of alkylene/(meth)acrylic acid copolymer and modified or unmodified polyvinyl alcohol is used in a layer of a layer composite, to the use of a coating composition for producing a layer composite.

Abstract: A heat-sensitive recording material has a web-shaped substrate, having a front side and a reverse side opposite the front side, a heat-sensitive recording layer disposed to the front side of the web-shaped substrate, including at least one dye precursor and at least one (color) developer reactive with this at least one dye precursor. A front-side surface of the heat-sensitive recording material is formed dehesively with respect to layers of adhesive applied to the reverse side of the web-shaped substrate. The dehesive front-side surface includes a furnish which is disposed above the heat-sensitive recording layer and comprises at least one release agent. A diffusion layer is formed between the furnish and the heat-sensitive recording layer. A method for producing a heat-sensitive recording material of this kind, and possibilities for its use.
