PROTECTIVE LAYER TRANSFER SHEET AND INTERMEDIATE TRANSFER MEDIUM |
(57) The purpose is to provide a protective layer transfer sheet and an intermediate transfer
medium, in which the protective layer has excellent foil tearing property during transfer
and in which sufficient durability can be imparted to the thermally transferred image.
The above problem is solved by a protective layer transfer sheet in which a transferable
protective layer (20) is provided on one surface of a substrate (1) so as to be peelable
from the substrate (1), wherein the transferable protective layer (20) has a layered
structure in which a first protective layer (3A), and a second protective layer (3B)
which is in contact directly with the first protective layer (3A), are provided in
this order from the substrate (1) ; the first protective layer contains an epoxy-cured
resin in which a reactive resin having a functional group capable of reacting with
an epoxy group and having a glass transition temperature (Tg) of not less than 60°C
is reacted with and cured by an epoxy curing agent; and the second protective layer
(3B) contains a polyester resin having a number-average molecular weight (Mn) of not
less than 8000 and a glass transition temperature (Tg) of not less than 45°C.
