摘要： There is a process for preparing in situ an aqueous gel ink with variable color having the following steps:
(i) preparing a gel-based matrix of aqueous ink comprising a reducing agent,
(ii) adding a solution of metallic salts,
(iii) adding iron powder to obtain an aqueous gel ink with variable color,
wherein the steps (ii) and (iii) can be interchanged.
There also is an aqueous gel ink with variable color obtained according to the process of the disclosure, having a reducing agent, metallic nanoparticles and iron powder.
There further is a writing instrument having an aqueous gel ink with variable color according to the disclosure.-
