A method of improving the dye lightfastness of acrylic polymer substrates by the incorporation of amino or hydroxy-substituted triazine compounds. Preferred Polymers comprise polyacrylonitrile and copolymers containing at least 80 percent acrylonitrile. Preferred lightfastness agents are triamino triazine and trihydroxy triazine in amounts from about 0.2 percent to about 5 percent, based on polymer weight.
