Abstract
The present invention relates to a polyurethane type casting coating showing high durability and used as labelling materials in labels, stickers, outdoor signs, reflective refractors, light road markings or automobiles. It is an object of the present invention to provide polyurethane type casting coatings for use in labelling materials by coating a solution consisting of a non-yellowing polyurethane-polyurea resin, an acryl type copolymers containing cross linkable groups such as hydroxylic groups or amide groups and a cross linking agent such as a blocked isocyanate or an aminoplast onto a releasable substrate and then cross linking the coating.
