Abstract
A composition for use in a thermal-sensitive paper coating and a heat-sensitive recording material utilizing the coating, which composition comprises a phenolic developer, e.g., a traditional low speed phenolic having a melting point greater than 120.degree. C., and a pseudo developer. The pseudo developer is combined with the phenolic developer in an amount effective to provide for the formation of homogenous phase when the composition is melted, which phase further solidifies back to a single crystalline phase when cooled.
