Abstract

In order to enable lamination of materials of different kinds, such as a synthetic resin plate and a glass plate, without leaving bubbles between the materials, a double sided adhesive sheet ( 1 ) is formed by forming an adhesive layer ( 3 ) cross-linked with ultraviolet light on one surface of a sheet ( 2 ) with an inorganic oxide layer ( 2 B) and forming an adhesive layer ( 4 ) cross-linked by heating or moisture on the other surface of the sheet ( 2 ). A glass plate ( 6 ) is applied to the adhesive layer ( 3 ), and a synthetic resin plate ( 7 ) is applied to the adhesive layer ( 4 ), thereby forming a laminate panel ( 5 ).

Claims (11)

1 - 6 . (canceled)

7 . A laminate panel, comprising:

a glass plate, a double sided adhesive sheet and a synthetic resin plate in this order;

wherein the double sided adhesive sheet has a constitution in which a first adhesive layer is formed on one surface of a sheet comprising an inorganic oxide layer, and a second adhesive layer is formed on the other surface of the sheet;

wherein the first adhesive layer adheres to the glass plate, the second adhesive layer adheres to the synthetic resin plate;

the first adhesive layer is cross-linked with ultraviolet light; and

the second adhesive layer is cross-linked by moisture or heating.

8 . The laminate panel according to claim 7 , wherein a thickness of the first adhesive layer is 100 μm to 2000 μm, and a thickness of the second adhesive layer is 10 μm to 50 μm.

9 . The laminate panel according to claim 7 , wherein the inorganic oxide layer comprises primarily at least one member selected from the group comprising silica (SiO 2 ), alumina (Al 2 O 3 ), zinc oxide (ZnO), indium tin oxide (ITO), tin oxide (SnO 2 ) and antimony tin oxide (ATO).

10 . The laminate panel according to claim 7 , wherein the first adhesive layer is made of an adhesive that has a glass transition temperature (Tg) of equal to or lower than −20 degrees C. and a holding force (JIS Z0237) of 2 mm to 12 mm in terms of displacement thereof.

11 . The laminate panel according to claim 7 , wherein the second adhesive layer is made of an adhesive that has a glass transition temperature (Tg) equal to or higher than −20 degrees C. and equal to or lower than 10 degrees C. and a holding force (Ms Z0237) of 0 mm to 0.5 mm in terms of displacement thereof.
