摘要： A process for tinting of articles molded from a polymeric resin is disclosed. Preferably, the article is molded from polycarbonate and the process entails immersing the molded article in a dye bath that contains water, dye, a carrier and an optional surfactant. The carrier is a compound conforming to formula (i): R 1 [-O-(CH 2 ) n ] m OR 2, wherein R?1¿ and R?2¿ independently denote H or C¿1-18? alkyl, benzyl, benzoyl or phenyl radical which may be substituted in the aromatic ring by alkyl and or halogen, preferably R?1¿=butyl, R?2¿=H, n is 2 or 3 and m is 2 to 35. The method is especially useful in the manufacture of tinted lenses.

摘要： 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.
摘要翻译：公开了一种热塑性模塑组合物，其包含适于通过浸染法调色的透明树脂成分。树脂组分选自（i）（共）聚碳酸酯树脂和（共）聚己内酯的共混物，和（ii）含有碳酸酯和己内酯结构单元的共聚物。该组合物的特征在于，其不含光致变色着色剂，可以通过热塑性方式成型，然后通过浸渍在着色溶液中将模塑制品浸渍染色。有色物品适用于制造光学透镜等。
