    Abstract: It is an object of the present invention to provide a novel photo-curing composition which can be cured by light of a wide wavelength region including ultraviolet light or visible light, has such high sensitivity that it can be sufficiently cured by exposure to a small amount of light, can favorably form a fine pattern when used as a resist and provides a cured product having excellent heat resistance and insulating properties, and a negative photoresist composition using the photo-curing composition. It is another object of the present invention to provide a process for highly accurately and easily producing a polyimide thin film used for a medical instrument, and a medical instrument having the polyimide thin film. The photo-curing composition of the present invention comprises (A) a carbon cluster and/or its derivative, having a photosensitizing function, (B) a compound having plural heterocyclic rings in a molecule, and if necessary, (C) a photo-insensitive resin.

    Abstract: A liquid crystal alignment agent containing at least two kinds of polymers selected from the group consisting of polyamic acids and imidized polymers and having a structure obtained by dehydration and ring closure of polyamic acid. In the at least two kinds of polymers contained in the liquid crystal alignment agent, the polymer of higher imidization degree has a smaller surface free energy. The liquid crystal alignment agent gives a liquid crystal display device having less stuck image and high pretilt angle.
