    摘要： A heat-resistant negative-working photoresist composition comprising a resin component having a carbodiimide unit in the molecule, and a compound capable of inducing a basic compound by irradiation with actinic rays. The photosensitive layer formed by the photoresist composition shows a sufficient sensitivity even by a lower irradiation energy and can give a sharp negative-type pattern by irradiation with actinic rays such as ultraviolet rays.

    摘要： A heat-resistant adhesive film, an adhesion structure obtained using the same, and an adhesion method using the same are disclosed, the film comprising a polyisoimide resin containing at least 40 mol % of an isoimide unit represented by formula (I): ##STR1## wherein R.sub.1 represents a tetravalent aromatic or aliphatic residue; R.sub.2 represents a divalent aromatic or aliphatic residue; and the arrow represents a bond replaceable on isomerization, in the molecule thereof. The isoimide unit of the polyisoimide resin is easily converted to an imide unit on heating, e.g., hot pressing with an adherend, to provide a cover-lay film or a single-sided or double-sided base for printed circuit boards having excellent adhesion, heat resistance, dimensional precision, and workability.

    摘要： A colorless transparent polyimide shaped article having as a main component at least one recurring unit selected from the recurring units of the formulae (I) to (IX). It is useful, for example, as an oriented film in liquid crystal display devices. The polyimide shaped article is produced by a process which comprises preparing a solution of a polyamide acid having as a main component at least one recurring unit selected from the recurring units of the formulae (V) to (VIII) in an amide-type organic polar solvent, forming a shaped article of the polyamide acid from the solution, and imidizing the resulting shaped article of the polyamide acid.

    摘要： A colorless transparent polyimide shaped article having as a main component at least one recurring unit selected from the recurring units of the formulae (I) to (III), which is useful, for example, as an oriented film in liquid crystal display devices. The polyimide shaped article is produced by a process which comprises preparing a solution of (A) a polyimide precursor obtained by reacting a diamino compound comprising as a main component at least one aromatic diamine having amino groups at the m-position selected from diamines of formulae (IV) to (VI) with a tetracarboxylic acid compound comprising as a main component a tetracarboxylic acid dianhydride of formula (VII) dissolved in (B) at least one organic polar solvent selected from N,N-dimethylacetamide, N,N-dimethylformamide, bis(2-methoxyethyl)ether, cresol and halogenated phenols; forming a shaped article of the polyimide precursor from the solution; and imidizing the resulting shaped article.
