摘要： PROBLEM TO BE SOLVED: To provide improved thermographic and photothermographic materials comprising a barrier layer suitable for providing physical protection while preventing diffusion of various chemicals from thermally developable materials in thermal development. SOLUTION: The thermally developable materials comprise a support having thereon one or more thermally developable imaging layers comprising a binder and, in reactive association, a non-photosensitive source of reducible silver ions and a reducer composition for the non-photosensitive source of reducible silver ions. The materials further comprise a barrier layer comprising a cellulose ether polymer, present over the same support surface as the one or more imaging layers, and remoter from the support than the one or more imaging layers.

摘要： PROBLEM TO BE SOLVED: To improve the post-treatment stability of a photothermographic material. SOLUTION: The black-and-white photothermographic material is sensitive at a wavelength greater than 700 nm, and includes a support having thereon one or more thermally developable imaging layers containing a binder and in reactive association, a photosensitive silver halide, a non-photosensitive source of reducible silver ions, a reducing composition for the non-photosensitive source reducible silver ions and a spectral sensitizing dye for the photosensitive silver halide which is a merocyanine dye or a cyanine dye having one or more thioalkyl, thioaryl or thioether groups. The one or more thermally developable layers further contain a substituted propenenitrile compound and one or more indolenine dyes as post-processing stabilizing compounds.

摘要： PROBLEM TO BE SOLVED: To improve image uniformity as well as to reduce mottle in a photothermographic imaging material. SOLUTION: A photothermographic material is provided which includes a support having thereon one or more thermally developable imaging layers comprising a binder and, in reactive association, a photosensitive silver halide, a non-photosensitive supply source of a reducible silver ion and a reducing composition for the non-photosensitive supply source of a reducible silver ion. The one or more thermally developable imaging layers further comprise one or more radiant ray absorbing compounds giving a total absorbance of >0.6 to 3 at the wavelength of exposure light. While the photothermographic material is conveyed at a speed of at least 5 m/min, the one or more thermally developable imaging layers are coated and dried. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a barrier layer for protection suitable for a thermally developable material. SOLUTION: A thermally developable material having the following (a) and (b) on a support is provided; (a) one or more thermally developable imaging layers comprising a binder and a non-photosensitive reducible silver ion source and a reducing composition for the non-photosensitive reducible silver ion source combined in such a way that they react and (b) a barrier layer disposed farther from the support than the imaging layers on the imaging layer side of the support and comprising a film-forming acrylic or methacrylic acid ester or amide polymer(s) that has at least 8,000 g/mole molecular weight and comprises recurring units derived from one or more polymerizable ethylenically unsaturated acrylic or methacrylic acid ester or amide monomers, wherein 15-100 mole % of the recurring units of the polymer are derived from monomers having hydroxy functionality.
