NEW MATERIAL:A bis type oxalic acid containing aryloxy group replaced with an alkoxy at the beta-position. EXAMPLE:Bis beta-m-methoxyphenoxyethyl oxalate. USE:An additive for recording material, especially an additive for heat-sensitive recording material, having more excellent effects than bisphenoxyethyl oxalate or beta-methylpheoxyethyl terephthalate has. PREPARATION:Oxalyl halide is reacted with two molecules of alcohols containing a specific aryl group at the beta-position in a solvent such as acetonitrile in the presence of an organic or inorganic base such as triethylamine to give an oxalic ester, the above-mentioned new substance. |
