Abstract

A laser imageable article includes an imageable layer that comprises the reaction product of a metal precursor and a reactant. The imageable article also includes a first boundary layer on a first side of the imageable layer, the first boundary layer being substantially transparent to laser radiation, and a second boundary layer on a second side of the imageable layer. The imageable layer may be imaged with a laser through the first boundary layer while maintaining the continuity of the first boundary layer. In a preferred embodiment, the imageable layer comprises the reaction product of an ion of one or more metals selected from columns 8, 9, and 10 of the periodic table of elements and a reducing agent selected from hypophosphorus acid and salts thereof, sodium borohydride, and dimethylamine borane. One preferred embodiment of the imageable layer comprises from 1 to 30 mole percent phosphorus and up to 99 mole percent nickel. Another preferred embodiment of the imageable layer comprises from 1 to 40 mole percent boron and up to 99 mole percent nickel.
