Abstract
Abstract A silver halide photographic light-sensitive material comprising a support having the first photographic structual layer comprising one or more layers on a side of the support and the second photographic structual layer comprising one or more layers on the other side of the support, in which at least one of the photographic structual layers comprises a silver halide light-sensitive emulsion layer, and the total amount of gelatin contained in the photographic structual layer comprising the silver halide emulsion layer is within the range of from 2.00 g/m² to 3.50 g/m². The uppermost layer of the photographic structual layer comprising the silver halide emulsion is formed by coating of a solution having a surface tention of from 15 to 26 dyn/cm, and the second photographic stuructual layer is coated and gelled between coating and drying of the first photographic structual layer. The photographic material is improved in the adaptability for super-rapid processing with the total duration of 20 to 60 sec. and the unti-scratch property.

Claim 1
Independent Claim
139 words
A silver halide photographic light-sensitive material comprising a support having the first photographic structual layer comprising one or more layers on a side of said support and the second photographic structual layer comprising one or more layers on the other side of said support, wherein at least one of said photographic structual layers comprises a silver halide light-sensitive emulsion layer, the total amount of gelatin contained in said photographic structual layer comprising said silver halide emulsion layer is within the range of from 2.00 g/m² to 3.50 g/m², the uppermost layer of said photographic structual layer comprising said silver halide emulsion layer is formed by coating of a solution having a surface tention of from 15 to 26 dyn/cm, and said second photographic stuructual layer is coated and gelled between coating and drying of said first photographic structual layer.
Claim 2
Dependent Claim
139 words
A silver halide photographic light-sensitive material comprising a support having the first photographic structual layer comprising one or more layers on a side of said support and the second photographic structual layer comprising one or more layers on the other side of said support, wherein at least one of said photographic structual layers comprises a silver halide light-sensitive emulsion layer, the total amount of gelatin contained in said photographic structual layer comprising said silver halide emulsion layer is within the range of from 2.00 g/m² to 3.50 g/m², the uppermost layer of said photographic structual layer comprising said silver halide emulsion layer is formed by coating of a solution having a surface tention of from 15 to 26 dyn/cm, and said second photographic stuructual layer is coated and gelled between coating and drying of said first photographic structual layer.
