PRODUCTION OF SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL HAVING GOOD SHELF STABILITY

摘要

PURPOSE:To obtain a titled material having the stable effect of a hardener right after coating and drying till the use by storing said material for at least 24hr in an atmosphere kept at and under 18-30 deg.C and 47%-62% relative humidity RH since the end of the coating and drying of a gelatin-contg. layer until the product is packaged. CONSTITUTION:The above-mentioned material is stored for at least 24hr in the atmosphere kept at and under 18-30 deg.C and 47-62% relative humidity RH since the end of the coating and drying of the gelatin-contg. layer until the product is packaged. The amt. of the gelatin signifies the total of the amt. of the gelatin in the entire layer on the side of a base where the layer contains a compd. A, and the amt. of the compd. A signifies the amt. of the compd. A in the entire layer on the side of the base where the layer contains the compd. A. The curing effect is slow if the ratio between the amt. of the gelatin and the amt. of the compd. A is >12.0 and the resistance to sticking is deteriorated if <3.5. The curing effect is slow even in the range of (gelatin [g])/(compd. A [g]) = 3.5-1.20 if the relative humidity is <47% RH. The resistance to sticking is inferior if the relative humidity exceeds 62% RH. The compd. A is a polyhydric alcohol having >=40 deg.C m.p. and >=2 hydroxyl groups in the molecule.
