Procedure

A mixture of 170 parts of p-phenylphenol, 22.5 parts of 80% paraformaldehyde, 1.7 parts of p-toluenesulfonic acid and 200 parts of toluene was allowed to react at 100° C. for 2 hours, and then the toluene and water were taken off by vacuum distillation. There was obtained a p-phenylphenol-formaldehyde resin having a softening point of 85° C. The thus obtained resin was used as a color developer.
