PURPOSE:To improve the dispersion stability by dispersing the multivalent metal-metallized material of specified salicylic acid resin in the presence of an anionic water-soluble polymer such as polyvinyl alcohol derivative having a sulfonic group in the molecule. CONSTITUTION:The multivalent metal-metallized material of the salicylic acid resin consisting of >=1 kind of building units 1 expressed by formulas I and II (R1, R2, R3, and R'3 are a hydrogen atom and 1-12 C alkyl, cycloalkyl, aralkyl, and aryl, and X and X' are a 1-5 C straight-chain group) and the building unit II expressed by formula III (R4 and R5 are hydrogen and 1-12 C alkyl, aralkyl, etc.) in a specified ratio is dispersed in the presence of an anionic water soluble polymer such as the polyvinyl alcohol derivative having a sulfonic group or its salt to prepare the ag. suspension of the multivalent metal-metallized material of salicylic acid resin. |
