Abstract:
A thermoplastic molding composition comprising a transparent resinous component suitable for tinting by dip-dye method is disclosed. The resinous component is selected from the group consisting of (i) a blend of (co)polycarbonate resin and (co)polycaprolacone, and (ii) a copolymer containing carbonate and caprolactone structural units. The composition, characterized in that it is free of photochromic colorants, may be molded by thermoplastic means, and the molded article is then dipped-dyed by immersion in a tinting solution. The tinted articles are suitable for making, among others, optical lenses.
