Zusammenfassung:	A water resistant coating composition for ink jet recordable substrates having a pH of less than 7, which includes: (a) an aqueous polyurethane dispersion; and (b) an aqueous solution of a nitrogen containing polymeric dye fixative compound. When applied to a suitable substrate, the coating composition allows for the recording of sharp, waterfast images. A coated ink recordable substrate is also disclosed, which includes a substrate having at least one side and at least one side of the substrate has a coating layer derived from the above described coating composition. Se describe una composicion de revestimiento resistente al agua para substratos imprimibles o registrables con inyeccion de tinta que tiene un pH de menos de 7, la cual incluye: a) una dispersion de poliuretano acuosa y b) una solucion acuosa de un compuesto fijador de colorante polimerico que contiene nitrogeno cationico. Cuando se aplica a un substrato adecuado, la composicion de revestimiento permite el registro o impresion de imagenes nitidas y resistentes al agua. Se describe tambien un substrato revestido registrable o imprimible con tinta, el cual incluye un substrato que tiene al menos un lado, y al menos un lado del substrato tiene una capa de revestimiento derivada de la composicion de revestimiento descrita arriba.
