This invention relates to glass microsphere (bead) coated articles (5) having an upper surface comprising a layer of low refractive index transparent glass microspheres (1) such as those made from recycled ordinary glass. The articles of the invention have an extremely smooth tactile feel and a low friction surface even though they can be prepared from glass microspheres intermixed with abrasive irregularly shaped glass particles (2). The invention relates to a method making the bead coated articles of the invention and transfer articles that can be used to make the bead coated articles of the invention.
Articles revêtus de microsphères (billes) de verre et dotés d'une surface supérieure comportant une couche de microsphères de verre transparent à faible indice de réfraction telles que celles constituées de verre ordinaire recyclé. Ces articles sont extrêmement lisses au toucher et présentent un faible coefficient de frottement en surface bien que l'on puisse les préparer à partir de microsphères de verre mélangées à des particules de verre abrasives de forme irrégulière. On décrit également un procédé de fabrication de ces articles revêtus de billes et des articles de transfert utilisables dans la fabrication desdits articles revêtus de billes.
