Title: MULTILAYER COMPOSITE PSA CONSTRUCTIONS
Abstract:
The present invention relates to improved performance multilayer PSA constructions useful for making labels. In one embodiment the invention relates to a multilayer PSA construction (10) comprising: (A) a multilayer adhesive laminate (10) having an overall thickness of less than about 100 microns and comprising (i) at least one composite PSA layer (16) comprising a continuous phase of a pressure sensitive adhesive and a discontinuous phase of non-adhesive filler particles, filler particle aggregate, or a mixture thereof, and (ii) at least one second PSA layer (14) which is in contact with the composite layer (16) and contains no filler or less filler then the composite layer, and (B) a facestock (12) which is in contact with and adhered to either the composite layer (16) or the second PSA layer (14) of the multilayer adhesive laminate (10).
