Description

technical field [0001] The invention relates to stamp ink, in particular to a children's stamp ink. Background technique [0002] Currently, most stamp inks on the market are oil-based. Oil-based stamp inks have the advantages of bright color, clear seal patterns, and non-diffusion. However, they use organic solvents, have a slow drying speed, and are easy to stick to other papers and become blurred. [0003] In recent years, with the introduction of the concept of environmental protection, some water-based stamp inks have appeared on the market, which dry quickly and are not easy to be blurred. However, such ink is not easy to erase when children use it and stains their hands and clothes, so it is not suitable for children.
