Abstract

The invention relates to an anti-fading stamp-pad ink and a preparation method thereof, and belongs to the technical field of stamp-pad ink. The stamp-pad ink is prepared from the following components by the weight percentage: 45%-65% of an oily solvent, 15%-35% of a soluble resin, 1%-3% of a non-ionic surfactant, 0.1%-0.5% of an antioxidant and 10%-30% of a colorant. The stamp-pad ink has the beneficial effects that the quality is stable, and the ink does not fade after long-term storage.

Description

Technical field [0001] The invention belongs to the technical field of printing ink, and specifically relates to an anti-fading printing ink and a preparation method thereof. Background technique [0002] Seals have a long history of use in my country and are mainly used as important tools for identification or signing on documents. Since documents with seals generally need to be stored for a long time, the requirements for stamping ink are extremely high. [0003] The printing inks currently used in the market cannot satisfy people's needs in terms of quality, color, and storage time. Especially in terms of office, finance, contracts, paintings and calligraphy and other legal factors and valuable commodities, in order to avoid many legal risks and collection risks caused by ink, the quality requirements for ink will be higher. [0004] However, the existing printing inks are difficult to meet the increasing demand of people, and mainly have the following shortcomings: the color is...
