The paint material composed of the cosmetic according to the present invention has the minimum characteristics as the paint by being used in combination with the diluent for the paint material, and can be equivalently used as the typical paint, and an effective use of the cosmetic to be discarded can be achieved. In particular, by using such diluent in combination, it is possible to expect favorable characteristics peculiar to the paint material based on the cosmetic in terms of a transparency, a quick-drying, a smell, and the like of a film when stretched and spread on a drawing paper as compared with the typical paint.
