Abstract

Le fluide d'enregistrement magnétique, comme une bande magnétique contient un nouveau lubrifiant, qui est le produit de réaction d'un mono- ou polyisocyanate avec une quantité équivalente d'un mono-alcool oléfinique ou aliphatique, une mono-amine ou de l'acide monocarbonique, la chaîne aliphatique ou oléfinique comptant 10 à 24 atomes de carbone. Des lubrifiants très appropriés sont les produits de réaction de Desmodur N avec l'alcool cétylique, stéaryque ou oleïque. Un excès du réactif d'alcool favorise davantage l'effet de lubrification Application : enregistrement magnétique.Magnetic recording fluid, such as a magnetic tape contains a novel lubricant, which is the reaction product of a mono- or polyisocyanate with an equivalent amount of an olefinic or aliphatic monoalcohol, a mono-amine or l monocarbonic acid, the aliphatic or olefinic chain having 10 to 24 carbon atoms. Very suitable lubricants are the reaction products of Desmodur N with cetyl, stearic or oleic alcohol. An excess of the alcohol reagent further promotes the lubricating effect Application: magnetic recording.
