Title: Heat sensitive diazo recording material
Inventor: MATSUOKA KATSUMI
IPC: G03C1/61
Filed: 1986-11-17
Abstract: Heat sensitive recording material is of the type containing in a sensitive layer a diazonium salt and a coupler (e.g. resorcinol) and optionally a basic substance which react to form a dye; the layer also contains a hindered phenol of which five general formulae are shown and numerous examples. The phenols may have a variety of substituents and the phenolic ring can be fused or linked to one or more other rings. Preferably one of the color-forming components is enclosed in microcapsules which rupture or become permeable when heated; the making of polyurethane capsules is described. Capsule size is 20 microns or less. The phenol can be inside or outside capsules. Amount by weight of the phenol, per part of the diazonium salt, is 0.01-5 parts in microcapsules and 0.05-20 parts as separate particles. Other additives can be present to improve heat coloration of lower melting point in the layer. The hindered phenol improves the storage life before recording with a facsimile or computer printer and it reduces background yellow fog after recording. <IMAGE>
