    摘要: A device for controlling cell arrangement having a pattern composed of a cell adhesive surface and a cell non-adhesive surface, which has a good selectivity of cell adhesion and which can provide a fine pattern of cells in high resolution by culturing cells in a usual manner. The device is prepared by a process which comprises applying a photosensitive, cell adhesive or cell non-adhesive polymer to a surface having a reverse cell adhesivity property to that of the applied polymer, and patternwise irradiating a light to the photosensitive polymer layer followed by development; a process which comprises patternwise irradiating UV or radiation to a cell non-adhesive surface to produce a cell adhesive functional group such as carboxyl group or amino group in the irradiated portion; or a process which comprises patternwise irradiating UV or radiation to a cell adhesive or non-adhesive surface made of plastics to produce a polymerization initiation site in the irradiated portion, and graft-polymerizing at least one monomer having the reverse cell adhesivity property to the plastic surface to produce a polymer on the irradiated portion of plastic surface.

    摘要: Fine patterns with high degree of resolution and high resistance to etching can be produced by coating a solution of a photosensitive composition comprising (a) an aromatic azide compound and (b) an alkaline-aqueous-solution-soluble polymer on a substrate, exposing predetermined portions of the coated photosensitive composition to ultraviolet light, developing with an alkaline aqueous solution to form a resist pattern, and etching the substrate using said resist pattern as a mask.

    摘要: 4'-Azidobenzal-2-methoxyacetophenone is an excellent photosensitive compound and can give a photosensitive composition together with an alkaline-aqueous-solution-soluble polymer which can be insolubilized in an alkaline aqueous solution by photochemical curing with 4'-azidobenzal-2-methoxyacetophenone, and if necessary together with an organic solvent, said composition showing a very small change in viscosity with the lapse of long time.
