Estimating the term…
Tape-like magnetic recording media having a nonmagnetic substrate and at least one layer applied to the substrate having incorporated into at least one of these layers, an inorganic needle-shaped pigment which serves as a supporting pigment and has a ratio of the average length to the average diameter of the pigment of at least 3, and the mean modulus of elasticity of the layers is not less than 15 Gpa in the longitudinal direction of the tape-like recording media.
A tape-like, magnetic recording medium I comprising a nonmagnetic substrate III, at least one layer applied to this substrate and, in at least one of these layers, an inorganic needle-shaped pigment II which is suitable as a supporting pigment and has a ratio of the average length to the average diameter of the pigment II of from 3:1 to 15:1, wherein the mean modulus of elasticity of the stated layers is not less than 15 GPa in the longitudinal direction of the tape-like recording medium I.
A method for modifying the mechanical properties of polymeric materials, wherein pigments VI or VII are incorporated into melts or solutions of polymeric materials or melts or solutions of compounds from which polymeric materials can be prepared, and the mixture is then cured or allowed to solidify.
