PURPOSE:To exactly detect a flaw and uniformly coat a pigment by mixing a heavy pigment and a body pigment. CONSTITUTION:5-20 Parts of white pigment obtained by mixing 3-50% of heavy pigment consisting of one or more of titanium oxide, zinc sulfied, white lead, lithopone, zinc white, and barium sulfate and 97-50% of body pigment having less than 3.5 in specific weight, 5-20 parts of aqueous silicate mineral powder, 0.05- 5 parts of surfactant, and 90-55 parts of water and/or organic solvent are mixed as a flaw detecting agent to thereby form a developer. |
