Title:
PRECOATED METAL PLATE
Document Type and Number:
WIPO Patent Application WO/2007/116670
Kind Code:
A1
Abstract:
This invention provides a precoated metal plate that can prevent the occurrence
of defects in an optical disk, and, at the same time, can maintain high peel strength
of an adherend to a resin film, and can realize easy adhesion of the adherend to
the surface of the resin film. The precoated metal plate comprises a metal plate
and a resin film provided on the surface of the metal plate. The resin film comprises
an epoxy resin matrix layer and soft beads dispersed in the epoxy resin matrix
layer. For the soft beads, the compressive strength at single bead 10% deformation
by a microcompression test is not more than 10 MPa. The content of the soft beads
is not less than 5% by mass and not more than 50% by mass based on the epoxy resin matrix
layer, and the average particle diameter of the soft beads is not less than 1.1
times and not more than 5 times the average thickness of the epoxy resin matrix
layer.
