A protective film for use with a polarizing plate has a support carrying a glare-proof layer. The glare-proof layer is a resin with coarse particles having an average particle size of 0.25 to 10 .mu.m, and fine particles having an average particle size of 0.1 .mu.m or less and a refractive index of 1.40 to 1.60, embedded in it.

Protective film of polarizing plate

A protective film for a polarizing plate comprises a resin film, and provided thereon, a layer comprising a polyol acrylate resin.

Protective film for polarizing plate

A magnetic recording medium having a magnetic layer and a backing layer on opposite sides of a support is disclosed. The backing layer comprises a binder resin, a conductive carbon black and an organic powder.

Magnetic recording medium

Disclosed is a magnetic recording medium which comprises a support, a magnetic recording layer and optionally a back-coating layer, at least of said magnetic recording layer and said back-coating layer containing a urethane resin having a yield point. The tape performances of the magnetic recording medium according to the present invention can be markedly improved by incorporating the urethane resin having a yield point.
