    摘要: The invention relates to a pressure-sensitive adhesive tape with improved room temperature handleability comprising an adhesive layer with at least one exposed surface and optionally a backing, wherein the pressure-sensitive adhesive layer comprises an epoxy/polyester based pressure sensitive adhesive which is crosslinkable upon exposure to actinic or e-beam irradiation and optionally heat, and comprises (i) 30-80% by weight of a polyester component comprising one or more amorphous polyesters compounds, (ii) 20-70% by weight of an epoxy component comprising one or more epoxy resins and/or monomers, (iii) 0-50% by weight of a hydroxyl-functional component containing one or more hydroxyl-containing compounds having a hydroxyl functionality of at least 1, and (iv) an effective amount of a photoinitiator component for crosslinking the pressure-sensitive adhesive, whereby the weight percentages refer to the total mass of components (i)-(iv) and add up to 100 wt. %, and which exhibits a holding power of at least 5 min.
