Copper phthalocyanine (CuPc, Pigment Blue 15), with the chemical formula C32H16CuN8, CAS number 147-14-8, and a molecular weight of 576.07, is a blue organic pigment. It appears as bright greenish-blue rod-shaped crystals or powder, is flammable, and exists in two crystal forms, α and β, with the β form being more stable. Its melting point is 600℃ (decomposes). It is insoluble in water, alcohols, and hydrocarbon solvents, but soluble in concentrated sulfuric acid, forming an olive-colored solution. Upon dilution, a blue suspension precipitates.
Pigment blue powder B12 is a new type of blue pigment developed by Zhongyang Chemical. It requires a small amount and can be used in combination with fluorescent whitening agents. It is widely used for whitening and brightening of EVA, polypropylene, nylon, and polyester fiber plastic products, and has excellent whitening effect, especially for recycled plastics.
Pigment Yellow 12is an organic synthetic yellow pigment, also known as C.I. Pigment Yellow 12, with the molecular formula C32H26Cl2N6O4, belonging to the chemical category. Its melting point is 317-322℃, density is 1.24-1.53 g/cm³, and it is a yellow powder, insoluble in water, slightly soluble in ethanol, and shows a reddish-orange luster in concentrated sulfuric acid.
Pigment Red 48:1, chemically named 4-[(5-chloro-4-methyl-2-sulfonylphenyl)azo]-3-hydroxy-2-naphthoic acid barium, also known as C.I. Pigment Red 48:1, 3133 Permanent Red 2BN, and by other names including Lithol Scarlet D 3700 and Pigment Red 48 barium salt, has the molecular formula C18H11BaClN2O6S, CAS number 7585-41-3, and biometrics code 1FYL.
It is primarily used in NC-type packaging printing inks, thickening in water-based inks; it does not bleed when coloring soft PVC, withstands heat up to 230℃/5min in HDPE, and is widely used for LDPE coloring. It is more lightfast than P.R. 48:1 and can also be used for PP pulp coloring. There are as many as 118 commercial brands on the market. It is mainly used for coloring inks, plastics, rubber, coatings, and stationery.
When used for coloring plastics (such as PVC, LDPE, and PP), it exhibits excellent migration resistance in soft PVC. At a transparent concentration of 0.2%, its lightfastness reaches level 6, superior to similar pigments such as Pigment Red 48:1 and 48:2. It is suitable for coloring packaging inks, coatings, rubber, and stationery, with 51 global brand names covering both industrial and consumer goods sectors.
