ABSTRACT:
An advantageous linerless label assembly is produced by substantially full face coating a first substrate web second face with a first pressure sensitive adhesive, and substantially full face coating a second substrate web first face with a second pressure sensitive adhesive that is physically or chemically incompatible with the first adhesive, and then bringing the first and second adhesives into direct contact with each other. The substrates are formed into discrete separable labels which may be in sheet, roll, or fan-fold configuration. The individual labels in the substrate can either have the leading edges of each aligned with each other, or the leading edges can be spaced from each other (e.g. about half the length of each of the labels). When physically incompatible adhesives are used, the first adhesive may be vegetable based, polyvinyl alcohol or ultraviolet reactivated adhesive, and the second acrylic. When chemically incompatible adhesives are utilized, the first may be an acrylate adhesive and the second a copolymer of that acrylate adhesive and acrylonitrile.
