A process is provided for producing polyhexamethylenimine by condensing hexamethylenediamine at 50.degree. to 300.degree. C. in the presence of a palladium catalyst. The process yields substantially linear, high-molecular-weight polyhexamethylenimines, especially novel polyhexamethylenimines having a molecular weight of at least 1,000. Polyhexamethylenimines having a molecular weight of at least 500 are useful as gelling agents for organic liquids.

A method for preparing a substrate having a light-shielding layer involves forming a photosensitive coating film on a transparent electrically conductive layer formed on a transparent substrate, exposing the photosensitive coating film via a mask exhibiting light transmitting properties, removing and developing the coating film for exposing the transparent electrically conductive layer and electrodepositing a dark-hued coating on the exposed transparent electrically conductive layer for forming the light-shielding layer, and heating the light-shielding layer. The substrate having the light-shielding layer has a volume resistivity of 1.times.10.sup.2 ohm.cm or higher and may be used for a counterelectrode substrate for a TFT array substrate incorporated in a liquid crystal display device.
