Patent number: 10854554Abstract: A compounded polymer material that can be laser marked is provided. The compounded polymer material includes an enhancer of nitrides, carbides, silicides, or combinations thereof. Upon forming the compounded polymer material into an article and exposing it to laser radiation, the irradiated portion of the compounded polymer material absorbs the laser radiation, increases in temperature, and forms a mark in the article. A lightness value difference (?L) between the mark and the non-irradiated portion of the article has an absolute value of at least 5, and the lightness value difference between the mark and the non-irradiated portion is greater than if the polymer material did not include the enhancer.Type: GrantFiled: October 18, 2018Date of Patent: December 1, 2020Assignee: Ferro CorporationInventors: Joseph E.
