Abstract:
(EN) Provided are: a curing agent for magnetic recording media, which contains a compound represented by general formula (1); a composition for magnetic recording media, which contains this curing agent for magnetic recording media; a method for producing a magnetic recording medium, which uses this composition for magnetic recording media; and a magnetic recording medium which comprises a magnetic layer on a non-magnetic supporting body, and wherein the magnetic layer is a cured layer that is obtained by curing the above-described composition for magnetic recording media. In general formula (1), X represents a monovalent heterocyclic group or a monovalent group represented by general formula (2); Z represents an m-valent organic group; and m represents an integer of 2 or more. In general formula (2), R1 represents an alkyl group; R2 represents a hydrogen atom, an alkyl group or an aryl group; and * represents the bonding position to the adjacent carbon atom.
(FR) L'invention concerne : un agent de durcissement destiné à un support d'enregistrement magnétique, qui contient un composé représenté par la formule générale (1); une composition pour supports d'enregistrement magnétiques, qui contient cet agent de durcissement pour supports d'enregistrement magnétiques; un procédé de production d'un support d'enregistrement magnétique, qui utilise cette composition pour des supports d'enregistrement magnétiques; et un support d'enregistrement magnétique qui comprend une couche magnétique sur un corps de support non magnétique, et la couche magnétique étant une couche durcie qui est obtenue par durcissement de la composition décrite ci-dessus pour des supports d'enregistrement magnétiques. Dans la formule générale (1), X représente un groupe hétérocyclique monovalent ou un groupe monovalent représenté par la formule générale (2); Z représente un groupe organique de valence m; et m représente un nombre entier supérieur ou égal à 2. Dans la formule générale (2), R1 représente un groupe alkyle; R2 représente un atome d'hydrogène, un groupe alkyle ou un groupe aryle; et * représente la position de liaison à l'atome de carbone adjacent.
