ABSTRACT:
A package for diazo thermosensitive recording materials coiled round a core, which comprises a packaging paper being a water vapor permeability of more than 50 g/m.sup.2.24 hours and comprising a light-reflecting paper layer located as outer layer and a light-shielding paper layer located as inner layer.
In the package of the invention, the packaging paper shields the recording material from the external heat and light. When internal humidity is increased such as by heating of the package such as higher than 50.degree. C., moisture passes through the packaging paper to the outside. Accordingly, fogging by precoupling of the packaged diazo thermosensitive recording materials, irrespective of the fixation type or not, is remarkably decreased, and the quality of the recording material can be maintained for a long period during storage.
