Title:

HEAT TRANSFER DONOR ELEMENT CONTAINING DIAZO COMPOUND

Document Type and Number:

Japanese Patent JPH1036331

Kind Code:

A

Abstract:

To obtain a heat transfer donor element comprising a compound having a diazo-substituted group and an electron-attracting group and high in decomposition temperature, a non-diazo electromagnetic ray-absorbing agent, and a heat substance transfer material and high in sensitivity for forming laser- induced thermal images.

This heat transfer donor element comprises (A) a diazo compound having a diazo-substituted group and at least one electron-attracting group adjacent to the diazo-substituted group and having a higher decomposition temperature than 250°C, such as a compound of formula I {R1 is H, a 1-4C aliphatic group, a group of formula II [(p) is 2-1000]; R2 is H, an organic group; (m) is 2-10}, (B) a non-diazo electromagnetic ray-absorbing agent and (C) a heat substance transfer material.
