\▐lac-kәr\ n [Portuguese lacré sealing wax, fr. laca lac, fr. Arabic lakk, fr. Persian lak] (1592) (1) A solution of a film-forming natural or synthetic resin in a volatile solvent, with or without color pigment, which when applied to a surface forms an adherent film that hardens solely by evaporation of the solvent. The dried film has the properties of the resin used in making the lacquer. The word derives from the lac insect, which secreted the resinous substance from which shellac solutions were (and stilla are) made. Today most lacquers are made with cellulosic, alkyd, acrylic, and vinyl resins. (2) Finish on Chinese and Japanese lacquer ware.
