Printed solvent

This pigment has little impact on the market today and is only occasionally found in printing inks or in office articles, for instance in colored pencils. Its shade is more reddish and its tinctorial strength superior to that of P.Y.l. The low specific surface area of the types which are still commercially available makes for good hiding in print. Solvent resistance and other fastness properties equal those of P.Y.l P.Y.2 is only slightly less lightfast than P.Y.l.

In order for a solvent to wet a substrate, its surface energy (surface tension) must be lower than that of the substrate. Since many common substrates such as polyester, polyimide, and polyacrylate all have surface energy values around 45 dynes cm", screen printing solvents are normally chosen to have surface tension values around 40 dynes cm . In this context, it should be noted that some common laboratory contaminants, such as silicone oils, have ultralow surface energy values (<22 dynes cm ), which means they must be excluded from screen printing apparatus.

Eihyl-l-buianol, b.p. 147 "C, is used in synthesis and as a solvent for printing inks and surface coatings. 

Dearomatized or not, lamp oils correspond to petroleum cuts between Cio and C14. Their distillation curves (less than 90% at 210°C, 65% or more at 250°C, 80% or more at 285°C) give them relatively heavy solvent properties. They are used particularly for lighting or for emergency signal lamps. These materials are similar to kerosene solvents , whose distillation curves are between 160 and 300°C and which include solvents for printing inks. 

Uses. Butyrolactone is principally consumed by the manufacturers by reaction with methylamine or ammonia to produce A/-meth5d-2-pyrrohdinone [872-50-4] and 2-pyrrohdinone [616-45-5] C H NO, respectively. Considerable amounts are used as a solvent for agricultural chemicals and polymers, in dyeing and printing, and as an intermediate for various chemical syntheses. 

Synthol coproducts include alcohols, ketones, and lower paraffins. They are used mainly as solvents in the paint and printing industries, although some alcohols are blended into fuels. In 1992 Sasol began producing 17,500 t/yr 1-butanol [71-36-3] from 5-07-acetaldehyde [75-07-0] and plaimed to start a plant to produce high purity ethanol [64-17-5] in 1993. Acetone [67-64-1] and methyl ethyl ketone [78-93-3] are two ketone coproducts sold as solvents.
