ABSTRACT:
Disclosed is a multi-layer color photographic light-sensitive material-packed unit for picture-taking in the form of a lens-combined picture-taking unit having an exposure function. The invention is characterized in that the size of the picture plane of the light-sensitive material in the unit is 3.0 cm.sup.2 or more, that the packed unit is further packaged with a moisture-proof bag, that the relative humidity in said moisture-proof bag is 65% or less at 25.degree. C. and that the absolute value of the curling of the said light-sensitive material is from -1 mm to +1.5 mm at the said relative humidity while the fluctuating value of the curling thereof is 1.5 mm or less. Also disclosed is multi-layer color photographic light-sensitive material-packed unit having the same photographic emulsion layer constitution and having the same photographic function, but which is characterized in that the unit body is made of a moisture-impermeable material and the parts of the body are constructed by thermal fusion so that the body may be moisture-impermeable.
Using the unit, images of high quality can be obtained even under high humidity conditions, and in addition, the unit can be stably stored for long periods and can give focused pictures even under high moisture conditions.
