摘要：NOVELTY - Developer of alkylsalicylate-phenolic resin containing metal chelate, which is used for non-carbon copying paper, and its preparing process. Said preparing process features that the p-alkyl or p-aryl substituted phenol, p-alkyl or p-aryl substituted salicylic acid, formaldehyde and multi-valence metal ions are used as raw materials to synthesize a modified metal-salicylate-phenolic resin and long-carbon-chain alkyl is introduced to benzene ring of salicylic acid. Said developer has the advantages of stable properties, high developing speed of 45-65%, low chromatic difference (63-78) and easy preparing it.
