Title:
熱現像感光材料、および画像形成方法
Document Type and Number:
Japanese Patent JP4113398
Kind Code:
B2
Abstract:
The present invention provides a photothermographic material including on one surface thereof a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent and a binder, and satisfying a relationship of image tone defined by Expression (1): (a*121t-a*117t)<2>+(b*121t-b*117t)<2><2, (1) wherein a*121t and b*121t each represent a value of CIELa*b* obtained by thermal development at a developing temperature of 121° C. for t (sec), and a*117t and b*117t each represent a value of CIELAB obtained by thermal development at a developing temperature of 117° C. for t (sec), the values occurring at an optical density of 1.2; and t represents a duration (sec) required to attain a maximum density when the material has been exposed to sufficient light for producing Dmax and is developed at 121° C. The invention also provides an image forming method using the photothermographic material.
