摘要: A process for making spectacle frame components having reproducible color patterns by molding using a polyepoxide, curing agent therefor and an organic dye of certain color, which is thermally degradable at temperature between about 140° C. 250° The molded solid component subjected to differential heating in accordance with first predetermined pattern cause exposed portions undergo distinct change different color. second may also be included that degrades the then intermediate two degradation temperatures.
