The invention relates to a wash-off label structure and an adhesive layer comprising a pressure sensitive hot melt adhesive layer sensitive to the washing conditions. According to an embodiment the adhesive layer comprises an acrylate composition curable with ultraviolet radiation and at least one modifier and comprises peel adhesion from the labelled surface at 50-80 °C in alkaline aqueous solution of at least 30 % less than the peel adhesion at room temperature of 23°C ±2 °C and relative humidity of 50% ±5%. The invention further relates to a use of the label for recyclable or reusable packages, and a combination of a package and a wash-off label.
