Article and method of making the same

Abstract

A method comprises exposing a particle coating disposed on a thermally-softenable film to a modulated source of electromagnetic radiation. The particle coating comprises distinct particles that are not covalently bonded to each other, and are not retained in a binder material other than the thermally-softenable film. Articles made by the method are also disclosed.

         18 . A method of making an article, the method comprising exposing a particle coating disposed on a thermally-softenable film to a modulated source of electromagnetic radiation, wherein the modulated source of electromagnetic radiation comprises a flashlamp, wherein the particle coating faces away from the modulated source of electromagnetic radiation, and wherein the particle coating comprises loosely bound distinct particles that are not covalently bonded to each other, and are not retained in a binder material other than the thermally-softenable film. 
     
     
         19 . The method of  claim 18 , wherein the particle coating comprises at least one of graphite or hexagonal boron nitride. 
     
     
         20 . The method of  claim 18 , wherein the particle coating consists essentially of graphite. 
     
     
         21 . The method of  claim 18 , wherein the particle coating comprises a powder-rubbed coating. 
     
     
         22 . The method of  claim 18 , wherein the particle coating is exposed to the pulsed electromagnetic radiation according to a predetermined pattern. 
     
     
         23 . An article comprising a thermally-softenable film having a particle coating disposed thereon, wherein the particle coating comprises distinct particles that are not chemically bonded to each other and are not retained in a binder material other than the thermally-softenable film, and wherein the change in transmittance is at most 60 percent after abrading the particle coating according to ASTM D6279-15 “Standard Test Method for Rub Abrasion Mar Resistance of High Gloss Coatings” with the 25 mm friction element being outfitted with a two inch square Crockmeter cloth soaked in isopropanol for three seconds. 
     
     
         24 . The article of  claim 23 , wherein the particle coating comprises a powder-rubbed coating. 
     
     
         25 . The article of  claim 23 , wherein at least one portion of the particle coating corresponding to a predetermined pattern has a greater transmittance to visible light than at least one portion of the particle coating that is not disposed within the predetermined pattern.
