| titleOfInvention |
Magnetic recording medium based on a polyurethane prepolymer containing hydroxyl and amino groups |
| abstract |
The present invention relates to a magnetic recording medium, comprising a non-magnetic support and at least one magnetic coating applied thereto, whereby said coating contains at least one finely distributed magnetic material dispersed in a binding agent. Said binding agent contains at least one polyurethane resin (PV, which can be obtained by cross-linking at least one polyisocyanate (A) with at least one polyurethane prepolymer (B) which is free of isocyanate groups and contains at least 3 active hydrogen atoms. The invention is characterised in that the polyurethane prepolymer (B) has at least two hydroxyl groups and at least one primary and/or secondary amino group. The invention also relates to a method for producing a magnetic recording medium, polyurethane prepolymers B) which are free of isocyanate and a method for the production and use thereof. |
