PURPOSE:To improve stability for aging and prevent malodor from developing by a method wherein at least one kind of cation-activated guar gum is added to correcting agent. CONSTITUTION:At least one kind of cation-activated guar gum is mixed with offset printing correcting agent, which utilizes silver print as ink receptable one, under the condition that enough loadings of the gum is about 0.1-10g per 100ml. The correcting agent can be employed in water, various alcohols and their mixed solvents. In the agent, thickening element such as carboxymethylcellulose or the like, coloring element such as inorganic pigment or the like may well be included. Further, compound, which has group strongly bonding with silver print and at least one hydrophilic group, can also be used in combination with the correcting agent. |
