  • Polyvalent metal salt of salicyclic acid resin and process for preparing it
    Patent number: 5525686
    Abstract: A process for preparing a polyvalent metal salt of a salicylic acid resin which comprises the steps of reacting salicylic acid or its derivative with styrene or its derivative at a temperature of -20.degree. C. or higher but lower than 40.degree. C. in the presence of sulfuric acid, and then reacting the resulting reaction product with a polyvalent metal compound; an aqueous dispersion in which the polyvalent metal salt of the resin is dispersed in water; and a developing sheet in which the polyvalent metal salt of the salicylic acid resin is used.
