    摘要： 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.

    摘要： A PROCESS FOR THE SIMULTANEOUS DYEING OR PRINTING OF TEXTILE FIBRE MIXTURES WITH CATIONIC AND ANIONIC DYESTUFF IS DISCLOSED EHIC COMPRISES IMPREGNATING OR PRINTING THE TEXTILE FIBRE MIXTURE, AT TEMPERATURES BELOW THE ABSORPTION TEMPERATURE OF THE DYESTUFFS, WITH AN OPTIONALLY THICKENED SOLUTION CONTAINING AT LEAST ONE CATIONIC AND AT LEAST ONE ANIONIC DYESTUFF, SUFFICIENT ACID AND BUFFER SALT FOR THE PURPOSE OF MAINTAINING A PH-VALUE OF THE SOLUTION OF BETWEEN 3 AND 7, AT LEAST 0.5 G./1. OF SULPHATED OR SULPHONATED COMPOUND AS ANION-ACTIVE AUXILIARY, AND AT LEAST 0.5 G./1. OF AN AMIDE OF ALIPHATIC MONOCARBOXYLIC ACIDS CONTAINING FROM 8 TO 20 CARBON ATOMS, OR OF MIXTURES OF SUCH FATTY ACIDS WITH PRIMARY OR SECONDARY AMINES CONTAINING AT LEAST ONE LOWER HYDROXYALKYL GROUP, AND/OR OF A WATERSOLUBLE CONDENSATION PRODUCT FROM 1 EQUIVALENT OF FATTY ACIDS HAVING FROM 8 TO 20 CARBON ATOMS OF FROM MIXTURES OF SUCH FATTY ACIDS WITH FROM 1 TO 3 EQUIVALENTS OF A DIAND/OR TRIALKANOLAMINE, AND, OPTIONALLY, FURTHER AUXILIARIES, AND FINISHING THE DYEING OR PRINT BY A MOIST HEAT TREATMENT. THEREBY, THE TEXTILE FIBRE MIXTURES ARE DYED OR PRINTED VERY EVENLY, IN ONE SHADE OR IN SEVERAL SHADES, WITH GOOD FASTNESS PROPERTIES AND WITHOUT THE SO-CALLED "SANDWICH-EFFECT."
