Abstract
This invention relates to a composite pressure sensitive adhesive composition comprising at least one first pressure sensitive adhesive material in the form of at least one continuous phase, and at least one second pressure sensitive adhesive material in the form of at least one discontinuous phase, said discontinuous phase being dispersed in said continuous phase. The invention also relates to a laminate having a composite pressure sensitive adhesive composition overlying the surface of a substrate, and to a process for making the foregoing laminate. The laminates can be used in making labels, tapes, and the like.
