Abstract
Abstract A method for forming an image is described, comprising developing a photosensitive element which comprises a support provided thereon a photosensitive layer containing at least a photosensitive silver halide, a binder, and a dye providing substance which forms or releases a diffusible dye by developing after or simultaneously with imagewise exposure thereof, transferring the thus-formed or released diffusible dye to a dye fixing layer of a dye fixing element, and thereafter separating said photosensitive element and said dye fixing element from each other, wherein at least one layer constituting said photosensitive element and said dye fixing element contains an oil component.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
138 words
A method for forming an image comprising developing a photosensitive element which comprises a support provided thereon a photosensitive layer containing at least a photosensitive silver halide, a binder, and a dye providing substance which forms or releases a diffusible dye by developing after or simultaneously with imagewise exposure thereof, transferring the thus-formed or released diffusible dye to a dye fixing layer of a dye fixing element, and thereafter separating said photosensitive element and said dye fixing element from each other, the improvement wherein at least one non-photosensitive layer constituting said photosensitive element and said dye fixing element and which layer is present between said dye fixing layer and said photosensitive layer upon transferring said diffusible dye, and which constitutes a surface layer after said photosensitive element and said dye fixing element are separated contains an oil component.
Claim 2
Independent Claim
138 words
A method for forming an image comprising developing a photosensitive element which comprises a support provided thereon a photosensitive layer containing at least a photosensitive silver halide, a binder, and a dye providing substance which forms or releases a diffusible dye by developing after or simultaneously with imagewise exposure thereof, transferring the thus-formed or released diffusible dye to a dye fixing layer of a dye fixing element, and thereafter separating said photosensitive element and said dye fixing element from each other, the improvement wherein at least one non-photosensitive layer constituting said photosensitive element and said dye fixing element and which layer is present between said dye fixing layer and said photosensitive layer upon transferring said diffusible dye, and which constitutes a surface layer after said photosensitive element and said dye fixing element are separated contains an oil component.
Claim 3
Dependent Claim
18 words
