ABSTRACT:
A process for multi-layer, co-coating preparation of a silver halide color light sensitive material comprising co-coating at least eight coating liquid compositions simultaneously onto a traveling support to form at least eight total layers comprising a lowermost layer adjacent to the support and at least seven outer layers adjacent to the lowermost layer, wherein the at least eight coating liquid compositions comprise a lowermost layer coating liquid composition and at least seven outer coating liquid compositions; the lowermost layer coating liquid composition has a viscosity of 15 to 100 cp; each outer layer coating liquid composition of the at least seven outer layer liquid compositions has a viscosity of at least 30 cp; and the at least seven outer layer coating liquid compositions have an arithmetic mean viscosity of 60 to 300 cp.
