Rosin fumarate ester

A folding carton ink is composed of a hard non-film forming styrene acrylic emulsion vehicle and a styrene acrylic solution vehicle. As an alternative, a film forming styrene acrylic emulsion vehicle and rosin fumarate ester solution vehicle are used. 

A pre-print corrugated ink is composed of a styrene acrylic emulsion colloid vehi-de and a rosin fumarate ester resin and/or styrene acrylic resin solution vehide. The physical properties of emulsions and resins used in pre-print corrugated ink are listed in Tabs 5.4 and 5.5 for. 

Rosin Modifications. This class includes modifications with phenolics, phthalic alkyds, maleic alkyds, and fatty acids and oils. Rosin modifications can be broken out roughly into rosin and rosin esters, unmodified, and rosin and rosin esters, modified. The unmodified classification can be broken down into esters esterified with glycerol and esters esterified with other alcohols. The rosin and rosin esters, modified can then be broken down to those modified with phenolic and other tar acid condensates, those modified with phthalic alkyds, and those modified with maleic or fumaric alkyds. This is a very complicated classification and great care must be exercised in order to keep the classes consistent and comparable over a period of years. 

In the THM-GC profile of the printing ink resin,dimethyl fumarate (peak 6) is detected, suggesting the presence of maleic or fumaric acid. Pentaerythritol is indicated by the presence of the tetra- and trimethyl ethers (peaks 7 and 8, respectively). Tertiary butyl phenol and methyl and dimethyl tertiary butyl phenols are detected as their methyl ethers (peaks 9, 10, and 11, respectively). Rosin acid methyl esters are detected with dehydroabietic acid and abietic acid methyl esters predominating (peaks 15 and 16, respectively). This resin is therefore diagnosed...

The most important rosin derivatives used in printing ink formulations are rosin oligomers and their esters, metal resinates, modified phenolic and alkyd resins, ester gums, maleic and fumaric acid adducts and their esters. Practically all types of printing inks can be manufactured with rosin-based components, because they provide good miscibility and compatibility with most film formers and other ink additives.
