Abstract
This invention relates to phosphoresent, polymer-containing compositions suitable for use in footwear and to phosphorescent shoes, shoe soles, and other molded or extruded shoe parts made from such compositions. One aspect of this invention is directed to a polymeric composition comprising: PA1 (a) between about 25 and 75% by weight of an elastomeric polymer; PA1 (b) between about 20 and 50% by weight of a processing oil; PA1 (c) between about 0.005 and 0.5% by weight of at least one stabilizer; and PA1 (d) between about 3 and 30% by weight of a phosphorescent pigment. This invention relates to phosphoresent, polymer-containing compositions suitable for use in footwear and to phosphorescent shoes, shoe soles, and other molded or extruded shoe parts made from such compositions.
