    • A method of infusing a dye into the surface of an article formed of a plastic material comprises contacting the surface with a solution including one or more solvents each aggressive to the plastic material, one or more dyes and one or more substances each capable of plasticizing the plastic material. If the plastic material is polycarbonate, then the aggressive solvent may be one or more chlorinated hydrocarbons. The dye may be a photochromic dye, a cosmetic tinting dye, dyes for absorbing infrared, laser and ultraviolet radiation, or combinations thereof. A wide range of plasticizers has been investigated. The article is contacted by the solution for ten seconds to one minute; and nearly all the infused solvent is then evaporated from the article by heating. The use of one or more plasticizers reduces or eliminates bubbling or hazing of the contacted surface during solvent evaporation. The dyed article comprises a surface layer having a depth of the order of magnitude of 100 microns containing one or more dyes, one or more plasticizers and, likely, a trace amount of the one or more aggressive solvents.
    • 将染料注入由塑料材料形成的制品的表面的方法包括使表面与包含一种或多种对塑料材料侵蚀的溶剂的溶液接触,一种或多种染料和一种或多种各自能够增塑的物质 塑料材料。 如果塑料材料是聚碳酸酯,则侵蚀性溶剂可以是一种或多种氯化烃。 染料可以是光致变色染料,化妆品着色染料,用于吸收红外线,激光和紫外线辐射的染料或其组合。 已经研究了各种增塑剂。 解决方案联系文章十秒钟至一分钟; 并且几乎所有输入的溶剂然后通过加热从制品中蒸发出来。 在溶剂蒸发期间使用一种或多种增塑剂减少或消除接触表面的起泡或起雾。 染色制品包括具有100微米量级的深度的表面层,其含有一种或多种染料,一种或多种增塑剂和可能的痕量的一种或多种腐蚀性溶剂。
