A thermoset resin for forming parts to be metal plated includes a vat photopolymerization (VPP) thermoset resin and an etchable phase disposed in the VPP thermoset resin. The etchable phase is etched from a surface of a part formed from the VPP thermoset resin such that a plurality of micro-mechanical locking sites is formed on the surface of the part. The etchable phase is at least one of organic particles, organic resins, inorganic particles, and copolymers of the VPP thermoset resin. For example, the etchable phase can be a polybutadiene phase and/or a mineral such as calcium carbonate.

A surface-treated copper foil including a treating surface, where the root mean square height (Sq) of the treating surface is in a range of 0.20 to 1.50 μm and the texture aspect ratio (Str) of the treating surface is not greater than 0.65. When the surface-treated copper foil is heated at a temperature of 200° C. for 1 hour, the ratio of the integrated intensity of (111) peak to the sum of the integrated intensities of (111) peak, (200) peak, and (220) peak of the treating surface is at least 60%.

A surface-treated copper foil includes a treating surface, and a peak extreme height (Sxp) of the treating surface being in a range of 0.4-2.5 μm, where the hysteresis loop of the surface-treated copper foil includes a first magnetization and a second magnetization when the magnetic field strength of the hysteresis loop is zero, and the absolute difference between the value of the first magnetization and the value of the second magnetization is in a range of 20-1200 emu/m.sup.3.

A decorative component includes a plurality of metal finish layers deposited over a substrate and a plurality of sub-layers. The outermost metal finish layer is selectively deposited or removed to define one or more recesses to create different appearances of the component. The outer metal layer may undergo laser ablation to remove at least a portion of the outer layer while still exposing the outer layer in the area of removed material. The recess may extend fully through the outer layer to expose the underlying metal finish layer, and/or the recess may have a sloped bottom surface to define a gradient appearance. The outer layer may be applied over a mask that is applied to the underlying layer, such that the outer layer is selectively applied. The outer layer may be removed to expose the underlying finish layer without exposing a nickel sublayer and without requiring a top coat.
