Abstract: Prelaminate pressure-sensitive adhesive (PSA) constructions comprise, a first substrate, a coating or release material on a surface of the first substrate, a PSA layer disposed on the coating of release material, and a detackified layer (DL) disposed on a surface of the PSA layer to form a continuous film covering the PSA layer. In first and second embodiments of the construction the DL is activatable to form a tacky layer on top of the PSA layer for lamination with a second substrate. In a third embodiment, the DL includes constituents that when activated migrate into the PSA layer to expose the PSA layer tacky surface for lamination with a second substrate. The prelaminate PSA constructions are completely nonblocking to a minimum 24 hour blocking temperature of about 50° C. at pressure of about 40 kilopascals, thereby allowing such prelaminate PSA construction to be collected, stored, and or transported before being laminated without adhesive interference occurring between continuous layers.
