Abstract
A black matrix for a color filter and method for forming the same which is safe inexpensive and provides good shielding performance and a low reflectance, and which is suitable for a paneling process. The black matrix is formed on a transparent substrate, and comprises a pattern of a resin composition containing a black pigment, physical development nuclei and a metal deposited on the physical development nuclei by physical development. The patterned resin composition is prepared from a photosensitive aqueous resin composition containing at least one black pigment.

A black matrix formed on a transparent substrate which comprises a pattern comprising a cured photosensitive aqueous resin composition containing at least one black pigment, physical development nuclei and a metal deposited on said physical development nuclei by physical development.
A method for forming a black matrix on a transparent substrate which comprises the steps of:
- forming a photosensitive aqueous resin composition layer containing physical development nuclei and a black pigment on said transparent substrate;
- patterning said photosensitive aqueous resin composition layer;
- and
- depositing a metal on said patterned resin composition layer by electroless deposition or by contacting the patterned resin composition layer with a donor sheet containing a metal compound via a developer for physical development.
A method for forming a black matrix on a transparent substrate which comprises the steps of:
- forming a photosensitive aqueous resin composition layer containing a black pigment on said transparent substrate;
- contacting said photosensitive aqueous resin composition layer with an aqueous solution of physical development nuclei to allow the photosensitive aqueous resin composition to adsorb said physical development nuclei;
- washing said resin composition layer containing the adsorbed physical development nuclei;
- patterning said washed resin composition layer;
- and
- depositing a metal on said patterned resin composition layer by electroless deposition or by contacting the patterned resin composition layer with a donor sheet containing a metal compound via a developer for physical development.
A method for forming a black matrix on a transparent substrate which comprises the steps of:
- forming a photosensitive aqueous resin composition layer containing a black pigment and physical development nuclei on said transparent substrate;
- exposing said resin composition layer;
- depositing a metal on said exposed resin composition layer by electroless deposition or by contacting the exposed resin composition layer with a donor sheet containing a metal compound via a developer for physical development to form a metal deposited resin composition layer;
- and
- developing said metal deposited resin composition layer.
