This invention relates to a tread rubber composition for tires with the addition of crosslinked resinous nanoparticles having a high glass transition temperature (Tg) into elastomeric base polymers. The invention demonstrates greatly improved handling performance without deteriorating controllability and stability during high-speed running. The present invention more specifically discloses a tire which is comprised of a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead and sidewalls extending radially from and connecting said tread to said beads; wherein said tread is adapted to be ground-contacting; and wherein the tread is comprised of a rubber composition comprising: (1) a rubbery polymer; (2) from 1 to 30 parts per hundred parts of rubber by weight of pre-crosslinked polymer particles, wherein the pre-crosslinked polymer particles have a mean number average particle size as determined by light scattering which is within the range of 30 nm to 500 nm, wherein the pre-crosslinked polymer is comprised of repeat units that are derived from at least one monomer selected from the group consisting of acrylate monomers, acrylonitrile monomer, and vinyl halide monomers, wherein the pre-croslinked polymer is in the form of core-shell particles having a core and a shell, and wherein the pre-crosslinked polymer has a glass transition temperature which is within the range of 30° C. to 200° C.; and (3) 10 to 150 parts per hundred parts of rubber by weight of at least one filler selected from the group consisting of carbon black and silica.

This invention relates to an aqueous film-forming mixture which does not contain a vinyl halide and which can be utilized to prepare conformable films which are useful in various applications such as adhesive tapes, labels and decorative sheets. The aqueous film-forming mixtures generally comprise, based on the weight of the solids in the aqueous mixture, (A) from about 50% to about 80% by weight of an acrylic-urethane copolymer which forms a film having an elongation at break of at least about 300%, and (B) from about 5% to about 25% by weight of an acrylic polymer or copolymer having a Tg of less than about 55° C., wherein the acrylic polymer or copolymer (B) is different from the acrylic-urethane copolymer (A). The aqueous mixtures also may contain up to about 40% by weight of a pigment. These aqueous film-forming mixtures are useful in preparing conformable films and other articles such as adhesive articles which comprise an adhesive layer and a layer of the conformable film of this invention which is adhered to the adhesive layer. The conformable films of the present invention may be printed with various graphics, and the films are die-cuttable.
