Document Type and Number:
WIPO Patent Application WO/2007/026765
Kind Code:
A1
Abstract:
This invention provides a process for producing a multilayered information
recording medium comprising two or more information recording parts and a resin
layer disposed between the information recording parts, wherein the assembly
is disposed on a signal substrate. The production process comprises a first step
of forming a predetermined information recording part on one main side of the
signal substrate and a second step of feeding a resin-containing coating material
onto a screen comprising a coating region with a plurality of first holes and a
removal region with a plurality of second holes, passing a part of the fed resin-containing
coating material through the plurality of the first holes by sliding a squeegee
on the screen to form a coating material layer onto the predetermined information
recording part, and curing the resin contained in the coating material layer
to form the resin layer. The production process is characterized in that the first
step and the second step each are carried out by a predetermined number of times.
In each second step, at least a part of the resin-containing coating material
remaining, on the screen, uncoated onto the predetermined information recording
part is passed through the plurality of second holes for removal from on the screen.
