INK JET MAGNETIC COMPOSITE RECORDING SHEET

摘要

PURPOSE:To provide an ink jet recording sheet excellent in color forming properties, ink absorbability and curling and also possible in magnetic data recording. CONSTITUTION:An ink jet magnetic composite recording sheet consists of a sheet like support composed of a biaxially stretched multilayered resin film containing a mixture of a polyolefin resin and inorg. pigment as a main component, the ink receiving coating layer formed on one surface of the support and based on an inorg. fine powder pigment and a binder resin and the magnetic recording layer formed on the opposite surface of the sheet like support and based on a magnetic powder and a binder. The heat shrinkage factor of the sheet like support measured at 100 deg.C by a heating stretchability test method entered in JIS-K-6734 is 0.5% or less in both of MD and CD-directions.
