PROBLEM TO BE SOLVED: To provide an aqueous drawing material which does not excessively flow out of an opening of a tubular container when it is used for making a drawing, in which a lustering material is not precipitated when it is not used and which is excellent in preservation stability. SOLUTION: The aqueous drawing material contains water, an organic solvent, the lustering material, a resin emulsion and a thickening agent at the least. The thickening agent contains a thixotropic thickening agent consisting of alkali-swelling polyacrylic acid together with a Newtonian thickening agent, wherein 3-1,500 parts by weight of the Newtonian thickening agent is contained for 100 parts by weight of the thixotropic thickening agent, and wherein 0.15-0.6 wt.% of the thixotropic thickening agent and 0.01-2.0 wt.% of the Newtonian thickening agent are contained based on the aqueous drawing material. The aqueous drawing material has 8,000-200,000 mPa s static viscosity and 1,000-20,000 mPa s kinematic viscosity. COPYRIGHT: (C)2010,JPO&INPIT |
