Zusammenfassung:	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. L'invention concerne un stratifié PSA comprenant au moins un stratifié non adhésif et au moins une couche collante; le stratifié non adhésif comprenant au moins une couche de pellicule frontale et au moins une couche adhésive de base; la couche de pellicule frontale comprenant au mois un matériau de pellicule frontale; la couche adhésive de base comprenant au moins un polymère adhésif de base; la couche collante comprenant au moins un agent collant; la composition collante n'étant pas un PSA; et la couche collante étant appliquée sur le côté de la couche adhésive de base du stratifié non adhésif afin d'obtenir le stratifié PSA. L'invention concerne également des procédés de fabrication du stratifié PSA, ainsi que des articles comprenant les stratifiés PSA.
