A layer of lanthanum boride of stoichiometry LaB.sub.x where x is between 9 and 12 is deposited on substrate, for example a stainless steel watch dial, and subsequently treated with a laser, such that the portion(s) of the layer treated with the laser change colour according to the laser power. This produces multicoloured surfaces having high resistance to corrosion and abrasion. The layer of LaB.sub.x is deposited by PVD and by cathode sputtering, using a LaB.sub.6 target of purple-violet colour, such that the colour of the deposited layer differs from the colour of the target. The laser treatment at specific powers changes the stoichiometry of the layer in the treatment portions, such that the colour of these portions changes according to the stoichiometry obtained. At higher powers, the laser will remove the layer of LaB.sub.x. Thus the colour of the treated portions is determined by the material of the substrate.

Disclosed herein is a method of forming a multilayer thin film by depositing target particles, detached from a target by plasma discharge of inert gas, on a metal object using a multilayer thin film deposition apparatus and a multilayer thin film formed by the method. More specifically, a sputtering deposition apparatus is used as the multilayer thin film deposition apparatus. The method includes coating a metal object with a coating layer, depositing at least one hardness-enhancing layer on the coating layer, and depositing a color layer on the at least one hardness-enhancing layer.

[Object] Provided are a laminate film and an electrode substrate film with excellent etching quality, in which a circuit pattern formed by etching processing is less visible under highly bright illumination, and a method of manufacturing the same.

[Solving Means] A laminate film includes a transparent substrate 60 formed of a resin film and a layered film provided on at least one surface of the transparent substrate. The layered film includes metal absorption layers 61 and 63 as a first layer and metal layers (62, 65), (64, 66) as a second layer, counted from the transparent substrate side. The metal absorption layers are formed by a reactive sputtering method which uses a metal target made of Ni alone or an alloy containing two or more elements selected from Ni, Ti, Al, V, W, Ta, Si, Cr, Ag, Mo, and Cu, and a reactive gas containing oxygen. The reactive gas contains hydrogen.
