Идентификационная магнитная карточка относится к приборостроению, а именно, к технике магнитной записи, в частности к носителям магнитной записи, и используется в автоматизированных банковских системах, здравоохранении, бензоколонках и т.п. Она содержит поливинилхлоридную основу, на одну из сторон которой нанесен магнитный слой с защитным покрытием. Новым является выполнение защитного покрытия из сополимера винилового спирта, винилацетата и винилацеталя с содержанием гидроксильных групп 1 - 5 мас.%. Такая карточка обладает повышенным сроком службы и малым процентом брака при изготовлении.The identification magnetic card relates to instrumentation, namely, to the technique of magnetic recording, in particular to magnetic recording media, and is used in automated banking systems, healthcare, gas stations, etc. It contains a polyvinyl chloride base, on one side of which a magnetic layer is coated with a protective coating. New is the implementation of the protective coating of a copolymer of vinyl alcohol, vinyl acetate and vinyl acetal containing 1–5 wt.% Hydroxyl groups. Such a card has an increased service life and a small percentage of defects in the manufacture.
