Abstract
Abstract A method for making a novel assembly of laid-on labels, without die-cutting, is described. The method comprises printing over the release surface of a temporary carrier web a liquid pressure-sensitive adhesive in a predetermined pattern of discrete label areas separated by intervening areas of the carrier, solidifying the adhesive surface, forming a continuous film of radiation polymerizable liquid over each adhesive area, the film over each area being unconnected to films over adjacent areas, and exposing the films to radiation sufficient to solidify them by polymerization. Preferably the films extend over the edges of the adhesive and comprise liquids which do not wet the release surface.
