Metal deco ink

P.Y.93 has no importance in the paint industry. The graphic ink field uses P.Y.93 only where fastness standards are high, such as in high grade packaging and metal deco inks. 

Uses Acrylic in clear coatings for vinyl, rigid plastics, wood, paper, screen ink vehicles, and metal deco inks Features Cures to soft, flexible film, exc. weathering props. 

The properties described above qualify quinophthalone pigments for applications including high quality industrial finishes, coloring of plastics and metal deco inks. Commercial products are supplied as powders, pigment preparations and liquid dispersions. 

P.Y.114 is primarily supplied to the printing ink industry, where it is used especially for packaging inks. The pigment is utilized to produce prints at reasonable cost, especially where exceptional fastness, as provided by P.Y.83, is a minor consideration. Prints made from P.Y.114 are not entirely resistant to a number of organic solvents, including the standard DIN 16 524 solvent mixture, paraffin, and butter but P.Y.114 prints are soap, alkali, and acid resistant. The fact that the pigment does not withstand a temperature of 140°C and is not stable to sterilization excludes P.Y.114 from use in metal deco printing. 

Commercially available P.O.46 types are usually quite transparent. They are employed primarily in packaging printing inks, also in offset and metal deco printing. Publication gravure inks, plastics, especially PVC, LDPE, and elastomers, as well as general industrial paints are suitable media for pigment application. P.O.46 is less solvent resistant than P.R.53 1, but it is faster to alkali and acid. In terms of lightfastness, P.O.46 performs poorly 1/3 and 1/25 SD prints equal only step 1 on the Blue Scale. 

P.Y.180 is becoming increasingly important and is utilized in printing inks to suit particular applications where diarylide yellow pigments cannot be used. Diary-lide yellow pigments decompose at temperatures in excess of 200°C (Sec. 2.4.1.3), which precludes their use in certain inks for metal deco which are baked at temperatures above 200°C. 

The printing ink industry uses P.Br.25 for all printing methods. The prints show excellent lightfastness. 1/1 to 1/25 SD letterpress proof prints, for instance, equal step 7 to step 6-7 on the Blue Scale. Prints made from P.Br.25 are fast to the DIN 16 524 standard solvent mixture, to paraffin, butter, soap, and acid, but they are not entirely fast to alkali. The products are fast to clear lacquer coatings and may safely be sterilized. The temperature stability is up to 240°C for 10 minutes or 220°C for up to 30 minutes, which makes P.Br.25 a suitable candidate for metal deco printing inks. It is also frequently applied in printing inks for PVC. 

P.R.221 is not recommended for use in polyolefins, since it also causes considerable distortion. It has, however, gained recognition as a pigment for high grade printing inks, especially for metal deco printing. 

Nonstabilized a-Copper Phthalocyanine Blue is utilized in the printing industry, to a certain extent in oil-based binder systems, such as offset printing inks for packaging and metal deco printing. Under standard conditions, P.B.15 is stable to a variety of organic solvents, such as alcohols, esters, ketones, aliphatic hydrocar-... 

Incorporated in printing inks, phase-stabilized a-Copper Phthalocyanine Blue, like nonstabilized types, is too reddish to be employed as a process color for three and four color printing. It is used, however, to a considerable extent in all types of printing inks for special and packaging purposes. The prints are stable to common organic solvents and exhibit perfect fastness properties in special application (Sec. 1.6.2.3). Metal deco prints withstand up to 200°C for 10 minutes or 170 to 180°C for 30 minutes. They may safely be sterilized. 

P.R.168 is found to a lesser extent in printing inks and plastics. The printing ink industry utilizes P.R.168 to produce special-purpose printing inks, which may be applied to substrates such as posters or metal deco prints. The pigment demonstrates equally excellent fastness in these materials. 1/1 SD systems equal step 8 on the Blue Scale for lightfastness, while 1/3 to 1/25 SD formulations match step 7. The prints are resistant to common organic solvents and chemicals. The pigment is thermally stable up to 220°C for 10 minutes, and its prints may safely be sterilized.
