发明名称 LAMINATED BODY FOR THERMAL TRANSFER AND MAGNETIC RECORDING MEDIUM
摘要 PROBLEM TO BE SOLVED: To provide a laminated body for thermal transfer having an easily releasable protective layer easily released from a release material (a supporting body for transfer) and having no trouble in adhesion properties to the other layer (e.g. a magnetic layer), in a laminated body for thermal transfer which is a constituent member of a magnetic card and the like and to provide a magnetic recording medium using the same. SOLUTION: Two or more cellulose derivative resins are used as constituent resins of the easily releasable protective layer of the laminated body for thermal transfer. At least two resins of them are essential component resins having hydroxyl group contents in regulated ranges (B: 2.5-3.5 mass%, C: 3.6 mass% or more) in the resins and the ratio of the two essential component resins and an other optional component resin in the protective layer resin is a regulated resin composition ratio (A/B/C=0-25/60-85/14-40 mass%).
