P.Y. 95
Ordinarily called:Yellow GR; Cromophtal Yellow GR; diazo condensation GR;Disazo Yellow GR
Chemical name:enzamide,3-3'-[2,5-dimethyl-1,4-phenylene)bis[imino(1-acetyl-2-oxo-1,2-ethanediyl)azo]]bis[4-chloro-N-(5-chloro-2-methylphenyl)-
Procedure of Synthetic Method:
    Be 2mol of 4 - chlorine 3 - amino-acid for diazotization, the resulting diazonium salt with 1mol of the 2,5 - double-acetyl-acetyl-amino-1,4 - dimethyl-coupling reaction carried out in o-dichloro - benzene medium (containing a small amount of DMF) in the preparation of pairs of azo dyes; and further reaction of thionyl chloride to prepare a product containing carboxyl chloride, and 5 - chloro -2 - methyl – aniline I n o-dichlorobenzene (for a small amount of the presence of pyridine) to condensation reaction of the crude pigment for paint treatment,prepared by CI Pigment Yellow 95

    TFCC P.Y. 95 has yellow color with red gloss, with perfect transparent quality, hue angle 88.7 degree(1/3S.D.,HDPE). It can replace the similar products which have famous brands in the world with its outstanding quality. It is widely applied in the coloration of ABS、HIPS、PP、PE、POM、TPR、TPE、PVC、PU process. Its heat-resistance quality can be as high as 290℃ in HDPE. That prevents the products from shrinking and warping; In PVC、TPR、PU and silicon gel production process, TFCC P.Y.95 has an excellent migration-fastness property. It is suitable for high quality printing ink because of its good dispersivity and good stability of flocculation.
P.Y. 191
Ordinarily called: PV Fast Yellow HGR
Chemical Name:4-chloro-2-[[4,5-dihydro-3-methyl-5-oxo-1-(3-sulfophenyl)-1H-pyrazol-4-yl]azo]-5-methyl-Benzenesulfonic acid,calcium(1:1)
Procedure of Synthetic Method:
 Diazo component of the 2 - amino -4 - methyl-amino -5 acid (2B-acid), soluble in ammonia, by adding hydrochloric acid to conduct acid analysis, cooling to 0-5 ℃, by adding sodium nitrite (30%) for diazotization, excess nitrous acid with ammonia to remove; prepared diazonium salt suspension and the coupling fraction 1 - (3'-sulfophenyl) -3 - methyl-pyrazolone -- 5, for coupling reaction, and then with calcium chloride the role of calcium into a lake, heating, filtration, washing, drying

TFCC P.Y. 191 has similar quality to C.I. P.Y.83. It has less color strength but has excellent heat-resistance. Its heat-resistance quality can be as high as 300℃ in HDPE. That prevents the HDPE products from shrinking and warping; Moreover, that provide a good light-fastness (7-8 grade) in HDPE. It has a good Migration-fastness in PVC. Its heat-resistance quality can be as high as 330℃ in Polycarbonate and organic solvent-resistance. It is also widely applied in the coloration of ABS、HIPS、PP、PE、POM、TPR、TPE、PVC、PU process.
