Abstract
(EN)
[Problem] To provide an ink composition in which adequate printability is obtained while using a material having a low environmental impact. [Solution] There is used an ink composition for offset printing that includes a pigment, a binder resin, and vegetable oils, wherein the ink composition for offset printing is characterized in that: the binder resin is not a resol derivative, and is such that dissolving 80 g of the binder resin by stirring for 30 minutes in 120 g of soybean oil heated to 200°C yields a dissolving varnish having an n-hexane tolerance of 2-7 g/5 g; and 10-30 mass% of a fatty acid alkyl ester of a vegetable oil is included relative to the entire composition as at least part of the vegetable oils.

La présente invention vise à fournir une composition d'encre dans laquelle une aptitude à l'impression adéquate est obtenue tout en utilisant un matériau ayant un faible impact environnemental. L'invention concerne par conséquent une composition d'encre pour impression offset qui comprend un pigment, une résine liante et des huiles végétales, la composition d'encre pour impression offset étant caractérisée en ce que : la résine liante n'est pas un dérivé de résol, et est telle que la dissolution de 80 g de la résine liante par agitation pendant 30 minutes dans 120 g d'huile de soja chauffée à 200 °C produit un vernis à dissoudre ayant une tolérance au n-hexane de 2 à 7 g/5 g ; et 10 à 30 % en masse d'un ester alkylique d'acide gras d'une huile végétale sont inclus par rapport à la composition entière en tant qu'au moins une partie des huiles végétales.
