Primer coating providing a metallized fabric exhibiting improved washfastness

This invention relates to metallized, particularly aluminized, fabrics which are coated with specific polyurethane finishes and primer coatings comprising novel phosphate-containing primers. Such specific polyurethanes are cross-linked when reacted with the primer coatings and applied in latex form. Upon impregnation within metal-coated fabrics, these particular polyurethanes encapsulate the metal particles and provide vastly improved washfastness properties to the fabrics and thus ensure the retention of substantially all the metal coating within and on the target fabric. The phosphate-containing primer provides remarkably improved adhesion between the metal and the polyurethane for excellent durability and washfastness. The primer compositions as well as the methods of producing a metallized coated with a primed polyurethane encapsulant are also provided.
