Abstract
Abstract Composite pressure sensitive label sheets will print in hot laser printers without curling if they comprise at least three layers: A. at least one base layer having a pressure sensitive adhesive on the bottom face, B. a printable surface layer on top of the base layer or layers, and C. a strippable protective backing on the pressure sensitive adhesive coated bottom face on the base layer or layers and if the thermal expansion or contraction characteristics of the printable layer B and the protective backing C are the same or substantially the same.
