Abstract
A surface treatment method for enhancing hydrophobicity of the surface of a film support is disclosed, comprising subjecting at least one side of the surface to a gas-discharge plasma treatment in a gas phase atmosphere comprising (a) an inert gas comprising argon or helium and (b) a reactive gas comprising a hydrocarbon gas or fluorinated hydrocarbon gas. There is also disclosed a photothermographic material by the use of the support having been subjected to the surface treatment.

A silver halide photothermographic material comprising a support having thereon a silver halide light sensitive layer, wherein at least one side of the support has been subjected in advance to a gas-discharge plasma treatment in a gas phase atmosphere comprising (a) an inert gas comprising argon or helium and (b) a reactive gas comprising a hydrocarbon gas or fluorinated hydrocarbon gas;
- the photothermographic material having the light sensitive layer provided on the side subjected to the gas-discharge plasma treatment.
A silver halide photothermographic material comprising a support having thereon a silver halide light sensitive layer, wherein at least one side of the support has been subjected in advance to a gas-discharge plasma treatment in a gas phase atmosphere comprising (a) an inert gas comprising argon or helium and (b) a reactive gas comprising a hydrocarbon gas or fluorinated hydrocarbon gas;
- the photothermographic material having the light sensitive layer provided on the side subjected to the gas-discharge plasma treatment and a backing layer on the other side of the support.
A silver halide photothermographic material comprising a support having thereon a silver halide light sensitive layer, wherein both sides of the support have been subjected in advance to a gas-discharge plasma treatment in a gas phase atmosphere comprising (a) an inert gas comprising argon or helium and (b) a reactive gas comprising a hydrocarbon gas or fluorinated hydrocarbon gas;
- the photothermographic material having the light sensitive layer provided on both sides of the support.
