Multilayer PSA label constructions that achieve a good balance of properties, namely, adhesive performance, convertibility, and laser printer performance, and, optionally, good wet-out on plastic substrates and low haze. The multilayer PSA construction comprising a facestock, a multilayer adhesive coating, and a release liner. The adhesive coating is made of a face side adhesive (FSA) layer comprising a first emulsion acrylic PSA, which is in contact with the inner surface of the facestock, and a liner side adhesive (LSA) layer, comprising a second emulsion acrylic PSA different from the first acrylic PSA, which is in contact with the FSA. The adhesive coating has a coat weight of less than about 26 g/m2 and a flow of less than about 50 μm at room temperature. The construction exhibits a loop tack value of at least about 3.5 N/25 mm at 5° C. on a polyethylene substrate. It has been discovered that multilayer PSA label constructions exhibiting these properties also exhibit good convertibility and laser printer performance.
