Abstract: A tackifier resin is provided comprising monomer units from at least one aromatic monomer and at least one acrylate monomer; wherein the tackifier resin has a low residual monomer concentration. In other embodiments of the invention, the tackifier resin does not significantly decrease the moisture vapor transport rate of an adhesive composition comprising the tackifier resin, does not significantly increase fogging of an adhesive composition comprising the tackifier resin, and does not significantly exhibit skin sensitivity properties. A process to produce the tackifier resin is also provided. The process comprises contacting a tackifier resin product stream with at least one carrier at a temperature sufficient to remove a portion of at least one residual monomer from the tackifier resin product stream to produce the tackifier resin.

Abstract: A PSA laminate is provided comprising at least one non-adhesive laminate and at least one tackifier layer; wherein the non-adhesive laminate comprises at least one facestock layer and at least one adhesive base layer; wherein the facestock layer comprises at least one facestock material; wherein the adhesive base layer comprises at least one adhesive base polymer; wherein the tackifier layer comprises at least one tackifier; wherein the tackifier composition is not a PSA; and wherein the tackifier layer is applied to the adhesive base layer side of the non-adhesive laminate to produce the PSA laminate. Processes for producing the PSA laminate are also provided as well as articles comprises the PSA laminates.

Abstract: A PSA laminate is provided comprising: a) at least one outer filmic layer (A) comprising at least one filmic polymer; b) at least one adhesive base layer (B) comprising at least one adhesive base polymer; and c) at least one tackifier layer (C) comprising at least one tackifier and at least one polymer; wherein the pressure sensitive adhesive laminate is obtainable by co-extruding the outer filmic layer (A) with the adhesive base layer (B) to produce a non-adhesive laminate and applying the tackifier layer (C) to the adhesive base layer side of the non-adhesive laminate to produce the PSA laminate. Processes for producing the PSA laminate, and articles comprising the PSA laminate are also provided.
