Abstract: PURPOSE:To provide the binder compsn. for a curing mold used in a molding method for self-curing and gas-curing molds and the process for production of a casting sand mold by using this compsn. CONSTITUTION:This binder compsn. for production of the ester-curing mold is formed by incorporating a water-soluble phenolic resin which is produced by effecting reaction in an acidic region by using a bivalent metallic ion catalyst in a stage for condensing phenols and aldehyde and effecting the reaction with an alkaline catalyst in an alkaline region in the stage before the above- mentioned stage and/or the stage thereafter into this compsn. and is incorporated further with a tervalent higher metallic compd. during the reaction into the compsn. The strength of th casting mold formed from a seclained sand is greatly improved by using the above-mentioned binder compsn. in the process for production of the sand mold for casting for molding a refractory granular material.
