    摘要： 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 &mgr;m 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.

    摘要： Inherently tacky infusible pressure-sensitive adhesive microspheres prepared by polymerizing at least one monomer which when polymerized will form a pressure-sensitive adhesive having a glass transition temperature less than about -20.degree. C. in a medium in which the monomer is substantially insoluble and in the presence of a surfactant and a suspension stabilizer which are soluble in the organic medium and substantially insoluble in the monomer under conditions of shear sufficient to form suspended particles of a size less than 200 microns. The formed microspheres are transferred to a volatile organic medium and separated from the medium in which they were formed by a centrifugal separator at a force of at least 2,000 times the force of gravity.

    摘要： Acrylic emulsion PSA polymers which when cast as a film resist water whitening by hot or ambient temperature water are provided, and are formed by copolymerizing a monomer mixture comprising at least one alkyl acrylate ester of an alcohol containing at least four carbon atoms, at least one polar comonomer and at least one partially water soluble comonomer present in an amount of at least about 7% by weight of the monomers. Polymerization is carried out in the presence of at least one nonionic surfactant containing at least about 8 moles of ethylene oxide per mole nonionic surfactant and at least one anionic surfactant containing up to about 10 moles ethylene oxide per mole anionic surfactant. There is added to the product of polymerization at least one base to produce an emulsion having a pH greater than 7 and containing particles having a mean “volume-average” particle diameter of up to about 210 nm as determined by laser light scattering. An electrolyte is post-polymerization added to stabilize opacity of the adhesive films cast from the emulsion. Applications include autoclavable labels, wet-stick container labels, fleet marking labels and battery labels.
