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 surface treatment method for enhancing hydrophobicity of a surface of a film support, the method comprising subjecting at least one side of the surface of said film support to a gas-discharge plasma treatment in a gas phase atmosphere comprising (a) an insert gas comprising argon or helium and (b) a reactive gas comprising a hydrocarbon gas or fluorinated hydrocarbon gas, and wherein the gas phase atmosphere contains not more than 750 ppm of oxygen.
A surface treatment method for enhancing hydrophobicity of a surface of a film support, the method comprising subjecting at least one side of the surface of said film support 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, and wherein the hydrocarbon is at least one of the group consisting of a saturated hydrocarbon represented by formula CnH2n+2 and unsaturated hydrocarbon represented by formula CnH2n or CnH2n−2, in which n is an integer of 1 to 12.
A surface treatment method for enhancing hydrophobicity of a surface of a film support, the method comprising subjecting at least one side of the surface of said film support 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, and wherein the fluorinated hydrocarbon is at least one of the group consisting of CH3F, C2H5F, C3H7F, C4H9F, C5H11F, and C6H13F.
A method for forming a silver halide photothermographic material having at least an image forming layer on a film support comprising the steps of:
- (i) subjecting at least one side of a surface of the film support 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 and
- (ii) coating at least said image forming therein a layer on the side subjected to the gas-discharge plasma treatment.
