Procedure

The weight average molecular weight of the thus-obtained salicylic acid resin was 960. The resin was placed in a separate reactor, to which a mixture of 16.3 g of zinc benzoate and 10 g of ammonium bicarbonate, which had been prepared in advance at 150-160° C, was added little by little over 30 minutes. After the addition, stirring was continued at the same temperature for 1 hour. The contents were taken out of the reactor, cooled and then ground, thereby obtaining 79.5 g of a zinc-benzoate-modified product of the salicylic acid resin. Its softening point was measured by the ring and ball softening point measuring apparatus in accordance with JIS K-2548. It was found to be 82° C.
