A composition for a black matrix is disclosed. The composition is composed of a black pigment and a binder for the pigment. The black pigment is a compound-oxide black pigment, which comprises at least two metal oxides and has a spinel or inverse-spinel crystalline structure. Also discloses are a process for the formation of a black matrix from the composition and an article provided with a black matrix so formed.

A process is disclosed for the production of connected microgel particles. According to the process, starting microgel particles having particle sizes of 100-0.01 .mu.m and a particle size distribution whose standard deviation is not greater than 100% of a mean particle size of the starting microgel particles are dispersed in a matrix component. The starting microgel particles are soaked with a monomer. The monomer is then polymerized, whereby the starting microgels are connected together. Also disclosed is an article comprising a base material and a layer of such connected microgel particles formed on a surface of the base material.
