Abstract:
Disclosed herein are methods of making an eyeglass frame comprising a frame front and/or a pair of temples, wherein each of the frame front and temples independently comprises a top layer and a patterned layer having the shape of a frame front and/or a pair of temples, and wherein the patterned layer comprises a laminate and a design pattern on a surface of the laminate, the method comprising the steps of: a) providing a mold having a cavity, wherein the shape of the cavity corresponds to the shape of the frame front and/or the temples; b) setting the patterned layer for the frame front and/or the temples in the mold; and c) injecting a melt of a first polymer composition into the cavity to form the top layer. In some embodiments, at least one of the frame front and temples further comprises a bottom layer.
