摘要:
The present invention provides a photo-sensitive and heat-sensitive recording material comprising a substrate supporting thereon a photo-sensitive and heat-sensitive recording layer containing a diazo compound and a coupler, wherein the diazo compound is a compound represented by the following general formula (1) and the diazo compound is enclosed in a microcapsule: wherein, R1 and R2 may be the same or different, and represent an alkyl group having 1 to 5 carbon atoms; R1 and R2 may be bonded to each other to form a ring; R3 and R4 may be the same or different, and represent an alkyl group; and R3 and R4 may be bonded to each other to form a ring. This photo-sensitive and heat-sensitive recording material reveals less change in the base concentration between before and after storage before use.
