Problems solved by technology

The drying performance of this kind of ink is worse than that of previous inks. When the printed products are stacked, it is easy to cause adhesion between the printing surface or between the printing surface and the paper, which is the so-called "bad sticky page". sex" question

Abstract

A drier for oxidative polymerization-drying printing ink is provided, which does not contain cobalt capable of exerting an adverse influence on the environment and health and which is environmentally friendly. A printing ink containing the drier is also provided. The drier for oxidative polymerization-drying printing ink contains an iron salt of a fatty acid and a manganese salt of a fatty acid.

Description

technical field [0001] The invention relates to a drier for oxidative polymerization drier printing ink and a printing ink containing the drier. Background technique [0002] In oxidative polymerization drying inks such as lithographic offset printing inks, a drying agent is added thereto in order to increase the drying speed after printing. As such a drier, generally, fatty acid manganese salt and fatty acid cobalt salt are used alone or in combination. [0003] Cobalt belongs to heavy metals. From the toxicity evaluation data in Table 1, it can be seen that cobalt is not a harmless metal. Among components contained in lithographic offset printing inks, it is a component that has a negative impact on the environment. Therefore, in order to obtain a lithographic offset printing ink that is more environmentally friendly or free from harmful components as much as possible, it is desirable not to use cobalt. However, considering that the negative impact on the environment is...
