Means for Solving the Problems The inventors of the present invention have conducted intensive studies to achieve the above object, and as a result, have found that a gold colloid solution is gelled with a divalent or higher valent metal salt solution in the presence of alginate. It has been found that a colloidal gold particle pigment exhibiting a stable color tone of magenta can be easily separated and collected in a short time. In addition, if a natural pigment is added to the gold colloid solution, it is possible to obtain a gold colloid particle pigment with a vivid color corresponding to the natural pigment without impairing the "safety for living organisms" that is the feature of gold colloid. We also learned that we can do it. For example, if a natural pigment such as safflower or cochinil is added to the colloidal gold solution, the resulting colloidal gold particle pigment will exhibit a vivid red (reddish) color of a commercially available tar-based pigment. .

The alginate is added to keep the colloidal gold particles which gel by the addition of a divalent or higher valent metal salt solution in a dispersed state to prevent agglomeration and make the particles uniform. The alginate is preferably sodium alginate from the viewpoint of availability and the like, but it goes without saying that the alginate is not particularly limited to sodium alginate. The alginate is preferably used in the form of an aqueous solution having a concentration of 1 to 3% (more preferably, an aqueous solution of about 2%). This is because the dispersibility of the colloidal gold particles is remarkably improved by making the alginate into an aqueous solution having a concentration of 1 to 3%, and the productivity of the uniform fine particles is further stabilized.
