Abstract
An inorganic pattern is formed by coating an inorganic substance-containing photosensitive composition comprising a photosensitive polymer (A), a condensable organic metal compound or a condensate thereof (B) and an inorganic filler having a functional group (C) on a base, exposing the coated layer, and developing the exposed layer to form a pattern, baking the pattern give an inorganic pattern. The photosensitive polymer (A) may be constituted of an oligomer or polymer, and a photosensitizer, and the condensable organic metal compound (B) may have a photosensitive group. The inorganic filler may be a monodispersed colloidal silica having a mean particle size of 2 to 100 nm. The proportions of the components (B) and (C) relative to 1 part by weight of the component (A) on a solid basis are about 1 to 25 parts by weight and about 1 to 20 parts by weight, respectively. Even when the content of an inorganic component is high, an inorganic pattern of high resolution can be formed with the use of the above resin composition.
