Abstract
PSAs and PSA constructions, such as self-adhesive labels, are provided, and exhibit good slittability and reduced adhesive build-up in printers, including laser printers. In one embodiment, a PSA has a storage modulus at 1000 radians/s and 25° C. of about 5×106 dyne/cm2 or higher and a creep at 90° C. of about 125 or less. In one embodiment, the PSA is the polymerization product of a plurality of acrylic and other monomers.
Claims27
A pressure-sensitive adhesive (PSA) construction comprising:
- a face stock, and
- a PSA laminated on the face stock, the PSA having a storage modulus ranging from about 5×106 dyne/cm2 to about 20×106 dyne/cm2 at 1000 radians/s and 25° C. and a creep (% strain) at 90° C. of less than about 125;
- wherein the construction, when comprising 50 lb paper face stock, results in a paper tear during a 90° Peel test at room temperature on stainless steel after 10 minutes with a force of at least about 1.0 lbs./in.
A pressure-sensitive adhesive (PSA;
- construction comprising:
- a PSA having a storage modulus ranging from about 5×106 dyne/cm2 to about 20×106 dyne/cm2 at 1000 radians/s and 25° C., a creep (% strain) at 90° C. of less than about 125, and a Tg than about 0° C.;
- and
- a face stock adhered to the PSA.
