ABSTRACT:
A safe and low cost process for forming a black matrix for a color filter, which process provides high light screening properties and is suitable for panel processing. The process comprises the steps of providing a transparent substrate having provided thereon an aqueous resin layer containing physical development nuclei; supplying a developer for physical development on the aqueous resin layer; superposing a donor sheet containing a metallic compound comprising metal ions on the aqueous resin layer via the developer for physical development; and precipitating a metal of the metallic compound in the aqueous resin layer by physical development. Furthermore, the aqueous resin layer may or may not be patterned.
