Title
(EN) COATING COMPOSITION FOR FORMING LASER-MARKABLE MATERIAL HAVING HEAT AND HUMIDITY STABILITY
(FR) COMPOSITION DE REVÊTEMENT PERMETTANT DE FORMER UN MATÉRIAU AYANT UNE STABILITÉ À LA CHALEUR ET À L'HUMIDITÉ ET QUI PEUT ÊTRE MARQUÉE PAR UN LASER
Abstract
(EN)
A laser markable coating composition suitable for CO2 laser markable materials, including at least one color forming agent and at least one waterborne solvent-free polyurethane, wherein the at least one waterborne solvent-free polyurethane is selected from a polyester-based polyurethane, polyether based polyurethane, polycarbonate-based polyurethane, and castor oil-based polyurethane, and wherein the at least one waterborne solvent-free polyurethane constitutes at least 50 weight percent of the total organic resin binder weight.
(FR)
L'invention concerne une composition de revêtement qui peut être marquée par un laser et qui convient pour des matériaux qui peuvent être marqués par un laser CO2. Ladite composition comprend au moins un agent de formation de couleur et au moins un polyuréthane à base d'eau sans solvant, le ou les polyuréthanes à base d'eau sans solvant étant sélectionné parmi un polyuréthane à base de polyester, un polyuréthane à base de polyéther, un polyuréthane à base de polycarbonate, et un polyuréthane à base d'huile de ricin, et le ou les polyuréthanes à base d'eau sans solvant constituant au moins 50 % en poids du poids total de liant de résine organique.
