    • This invention relates to a method of dyeing thermoplastics with sulfonated monoazo colorant lakes having a sulfophenyl pyrazole substituent, of general formula ##STR1## wherein R is CH.sub.3 or COO.sup.- ; X is Cl, CH.sub.3, CH.sub.3 O, C.sub.2 H.sub.5 O, C.sub.2 H.sub.5 CONH, NH.sub.2 CONH, C.sub.6 H.sub.5 CONH, CH.sub.3 SO.sub.2 NH, C.sub.6 H.sub.5 SO.sub.2 NH, CH.sub.3 CONH, or hydrogen; Y is hydrogen, Cl, or CH.sub.3 ; Z is hydrogen or Cl, n is 0, 1 or 2; and Me.sup.+ is one equivalent of a cation selected from the group consisting of NH.sub.4.sup.+, Li.sup.+, K.sup.+, Na.sup.+, 1/2Sr.sup.2+, 1/2Mn.sup.2+, 1/2Ni.sup.2+, 1/2Ba.sup.2+, 1/2Mg.sup.2+ and 1/2Ca.sup.2+ ; with the proviso that if R is COO.sup.-, the additional equivalent charge is compensated by a further equivalent of said or another cation. These compounds, which are insoluble in organic solvents and sparingly soluble in water, are useful as lakes with good pigmentary characteristics and possessing very good lightfastness in plastics, such as polyolefins, polyvinyl chloride, polystyrene, and ABS. They are also useful in surface coatings, and particularly suitable for coloring thermoplastics. Noteworthy is their good plasticizer fastness, their high stability to heat and the absence of blooming they produce when used.
    • 本发明涉及一种通过具有通式(I)的磺酰基苯基吡唑取代基的磺化单偶氮染料盐染色热塑性塑料的方法,其中R是CH 3或COO-; X是Cl,CH 3,CH 3 O,C 2 H 5 O,C 2 H 5 CONH,NH 2 CONH,C 6 H 5 CONH,CH 3 SO 2 NH,C 6 H 5 SO 2 NH,CH 3 CONH或氢; Y是氢,Cl或CH 3; Z是氢或Cl,n是0,1或2; 和Me +是选自NH4 +,Li +,K +,Na +,1 / 2Sr2 +,1 / 2Mn2 +,1 / 2Ni2 +,1 / 2Ba2 +,1 / 2Mg2 +和1 / 2Ca2 +的阳离子的1当量。 条件是如果R是COO-,则额外的等效电荷由另外的等价的所述阳离子补偿。 这些不溶于有机溶剂并微溶于水的化合物可用作具有良好颜料特征的湖泊,并且在塑料如聚烯烃,聚氯乙烯,聚苯乙烯和ABS中具有非常好的耐光性。 它们也可用于表面涂层,特别适用于着色热塑性塑料。 值得注意的是它们具有良好的增塑剂坚牢度,它们对热的高稳定性和使用时不产生起霜。
