PRODUCTION OF LIGHT CONTROLLING PLASTIC BASE MATERIAL

摘要: PURPOSE:To prevent production of uneven density due to changes in thickness a base material by leaving/dipping the at specified temp. coexistence sealed system liquid phase which an org. light-controlling is dissolved or dispersed and gas vapor light- controlling diffused CONSTITUTION:A plastic left and/or dipped diffused. By this method, permeates into efficiently obtain having surface layer impregnated with org, material. The leave dip preferably maintained higher than vaporization sublimation variation not produced. Once material, hardly released from
