Claim:
1. A method for providing an article, comprising: providing a metal catalytic pattern composed of a non-aqueous metal catalytic composition on a substrate, the non-aqueous metal catalytic composition comprising, in admixture: (a) a silver complex comprising reducible silver ions, in an amount of at least 2 weight % and up to and including 25 weight %, wherein the silver complex is silver acetate, silver benzoate, silver nitrite, silver oxide, silver sulfate, silver thiocyanate, silver carbonate, silver myristate, silver citrate, silver phenylacetate, silver malonate, silver succinate, silver adipate, silver phosphate, silver perchlorate, silver tetrafluoroborate, silver acetylacetonate, silver lactate, silver oxalate, silver 2-phenylpyridine; a silver fluoride complex; a β-carbonyl ketone silver (I) complex; a silver protein; or a combination thereof, (b) an organic phosphite in an amount of at least 2 weight % and up to and including 10 weight %, wherein the organic phosphite is tri-iso-propyl phosphite, tri n-butyl phosphite, tri-iso-propyl phosphite, tri-iso-butyl phosphite, triamyl phosphite, tri-n-hexyl phosphite, tri-n-octyl phosphite, tri-n-nonyl phosphite, tri(ethylene glycol) phosphite, tri(propylene glycol) phosphite, tri(iso-propylene glycol) phosphite, tri(n-butylene glycol) phosphite, tri(iso-butylene glycol) phosphite, tri(n-pentylene glycol) phosphite, tri(n-hexylene glycol) phosphite, tri(n-nonylene glycol) phosphite, tri(diethylene glycol) phosphite, tri(triethylene glycol) phosphite, tri(polyethylene glycol) phosphite, tri(polypropylene glycol) phosphite, or tri(polybutylene glycol) phosphite, or a mixture thereof, (c) an oxyazinium salt silver ion photoreducing agent in an amount of at least 2 weight % and up to and including 25 weight %, (d) a hindered pyridine in an amount of at least 5 weight % and up to and including 20 weight %, wherein the hindered pyridine in a compound having an alkyl group having 1 to 18 carbon atoms, a phenyl group or a naphthyl group in an ortho position on the pyridine ring (e) a photocurable component, non-curable polymer, or combination of a photocurable component and a non-curable polymer in an amount of at least 10 weight % and up to and including 88 weight %, and (f) a photosensitizer different from all components (a) through (e) in the non-aqueous metal catalytic composition, in an amount of at least 1 weight % and up to and including 10 weight %, all amounts being based on the total amount of components (a) through (f) in the non-aqueous metal catalytic composition, to provide a precursor article comprising the metal catalytic pattern composed of the non-aqueous metal catalytic composition; photoreducing the reducible silver ions to silver particles in the metal catalytic pattern by imagewise exposure of the precursor article to radiation having a wavelength of at least 150 nm and up to and including 700 nm; electrolessly plating a metal other than silver onto the silver particles in the metal catalytic pattern, or removing organic phosphite from metal catalytic pattern, and electrolessly plating a metal other than silver onto the silver particles in the metal catalytic pattern,
