MAGNETIC RECORDING CARRIER

PURPOSE: To improve the weatherability of a magnetic film by incorporating specific hydrocarbon into a magnetizable layer at a specific ratio of a magnetizable material. CONSTITUTION: The magnetizable layer contains hydrocarbon of carbon atomicity of 16 to 40 having 3 to 10 pieces of satd. branch po...

Zusammenfassung:	PURPOSE: To improve the weatherability of a magnetic film by incorporating specific hydrocarbon into a magnetizable layer at a specific ratio of a magnetizable material. CONSTITUTION: The magnetizable layer contains hydrocarbon of carbon atomicity of 16 to 40 having 3 to 10 pieces of satd. branch positions at a ratio of 0.1 to 2.0wt.% of the weight of the magnetizable material. The more preferable hydrocarbon is such that polyisobutene of carbon atomicity of 16 to 32 having 4 to 8 pieces of the satd. branch positions and more particularly, the polyisobutene of carbon atomicity of 22 to 28 having 5 to 7 pieces of the satd. branch positions occupy therein at least up to 60%. As a result, the weatherability is improved.
