Abstract
A diazo type recording material, which has a substantially unstained background, a superior preservability, and is capable of producing images of high density, wherein the diazo recording material comprises a support having thereon a recording layer comprising a photosensitive diazo compound, a hydroxyphenylsulfone derivative and a coupling component which forms a color by reacting with the diazo compound, with the diazo compound being enclosed in microcapsules.
Claims13
A recording material, comprising a support and a recording layer located on said support, said recording layer comprising a photosensitive diazo compound, a hydroxyphenylsulfone deriative and a coupling compound, wherein said photosensitive diazo compound, said hydroxyphenylsulfone derivative and said coupling compound are each present in an amount whereby said coupling compound forms a color upon reaction with said diazo compound and occurrence of background stains in said recording material is substantially prevented, and wherein said diazo compound is encapsulated in microcapsules.
