  • Publication number: 20090214827
    Abstract: The present invention relates to a composition comprising rubber modified thermoplastic resins which show special visual effects such as a metallic sparkle effect and/or other special visual effect from the surface of thermoplastic articles comprising the composition. In a particular embodiment the present invention relates to a composition comprising: (i) a rubber modified thermoplastic resin comprising a discontinuous elastomeric phase dispersed in a rigid thermoplastic phase, wherein at least a portion of the rigid thermoplastic phase is grafted to the elastomeric phase, and (ii) a plurality of microsphere beads having a diameter in a range of about 1 to about 1300 microns and having an index of refraction ranging from about 1.4 to about 2.5, wherein the microsphere beads are present in the composition in an amount in a range of between about 1 phr and about 14 phr, and wherein the microsphere beads provide a special visual effect on the surface of an article made from the composition.
