Cyclische N-Vinylacylamine werden hergestellt durch Erhitzen von Kohlensäureestern cyclischer N-2-Hydroxyethyl-acylamine in Gegenwart katalytischer Mengen alkalisch reagierender Verbindungen von Alkali- oder Erdalkalimetallen und anschließender Destillation des Reaktionsgemisches.
Die cyclischen N-Vinylacylamine sind wertvolle Vorprodukte zur Herstellung von Pflanzenschutzmitteln und von Arzneimitteln und dienen als Polymerisations-und Copolymerisationskomponenten zur Herstellung von Kunststoffen, Überzügen, Lacken und Ionenaustauschern.

An ultraviolet ray curing type resin composition comprising (A) an urethane acrylate produced from, as essential ingredients, an isocyanate compound comprising an aliphatic isocyanate compound and an alicyclic isocyanate compound at a molar ratio of from 80/20 to 20/80; a polyol compound comprising an ester-based polyol, an ether-based polyol or a polycarbonate-based polyol; and an acrylate compound having a hydroxyl group, (B) an acrylate-based reactive diluent, and (C) a photo-reactive initiator. The coated film obtained by coating the composition to a substrate, followed by photocuring has a following capability in molding owing to its excellent elongation, and only-causes a low level of yellowing upon long time heating to show an excellent thermal resistance. The cured product has a decreased residual odor and, therefore, useful in improving designing property and beauty in using for an automobile interior or the like. Further, the composition is suitable for forming a matted surface by printing to a substrate.

A multi-stage gasket having a multi-stage structure constituted by multiple kinds of gasket materials and being used by holding between a cover plate and a base plate, the multi-stage gasket having contactness of a gasket as the lowermost layer to the cover plate or the base plate in contact with the gasket that is higher than contactness of a gasket as the uppermost layer to the cover plate or the base plate in contact with the gasket.
A gasket can be provided that provides good reworkability of a cover plate and a base plate of a hard disk device, provides sufficient adhesiveness of the gasket to a cover plate and a base plate even when used in a high humidity and temperature environment, and is prevented from being toppled sideways or peeled off even when applied with a force in an oblique direction.
