Title:
RADIATION CURING COMPOSITION CONTAINING POLYIMETHYLSILOXANE
Document Type and Number:
Japanese Patent JPH08329520
Kind Code:
A
Abstract:
To reduce frictional coefficient of a magnetooptic recording disc with respect to a magnetic head by coating the disc with a specified radiation curing composition containing radiation curing components.
A magnetooptic recording disc is coated with a radiation curing composition composed of radiation curing components and a radiation curing polydimethylsiloxane compound containing polyoxyalkylene segment. The polydimethylsiloxane compound is compatible to the radiation curing components and the cured composition has allowable appearance. Orange texture and cloudiness are suppressed from the surface of the cured composition and frictional characteristics thereof are enhanced.
