Abstract:
A color laser markable laminate includes at least a transparent polymeric support and a color forming layer including a leuco dye; an infrared dye; and a polymeric binder including vinyl acetate and at least 85 wt % of vinyl chloride based on the total weight of the binder; wherein the color laser markable laminate includes a specific phenol stabilizer sterically hindered by a ring containing three nitrogen atoms. A method for preparing a color laser marked document is also disclosed.
