Disclosed herein is a first solid drawing material comprising water, a coloring agent, a solidifying agent that is a fatty acid alkali metal salt, and an O/W type emulsion of a separating agent that is an oily material which hardly volatilizes at room temperature. The first solid drawing material preferably contains silicone oil. A second solid drawing material is also disclosed, which comprises an organic solvent, a coloring agent, a solidifying agent that is at least one selected from the group consisting of dibenzylidene sorbitol, tribenylidene sorbitol, and derivatives thereof, a separating agent that is an oily material which hardly volatilizes at room temperature, and a resin soluble in the organic solvent. In these solid drawing materials, the separating agent is evenly dispersed, and therefore they have stable drawing properties and erasability.
本文公开了一种第一固体绘画材料,包括
水、
着色剂、固化剂,其为
脂肪酸碱
金属盐,以及一种分离剂的O/W型乳液,其为在室温下几乎不挥发的油质材料。第一固体绘画材料最好含有
硅油。还公开了一种第二种固体绘画材料,其中包括有机溶剂、
着色剂、固化剂,其至少选自双
苯基
山梨醇、三
苯基
山梨醇及其衍
生物的群组中的一种,一种在室温下几乎不挥发的油质材料分离剂,以及在有机溶剂中可溶的
树脂。在这些固体绘画材料中,分离剂均匀分散,因此具有稳定的绘画性能和可擦除性。
