摘要：
A patterned metallized film (10) comprises a transparent or translucent polymeric film coated on one side with a thin coating of metal, with the metal coating and the polymeric film being bonded to each other. The metal coating has a multiplicity of fractures of different sizes distributed throughout the coating in a prescribed pattern (12) so that the reflection of light by the fractured metal coating produces a three-dimensional illusion of the pattern (12) when viewed through said polymeric film. The film may also include a layer of adhesive on the opposite side of the metal coating from the polymeric film, and a paper backing sheet on the opposite side of the adhesive layer from the metal coating. The fractures are preferably formed by heating the metallized film non-uniformly so that selected areas of the film expand and soften at a rate different from the rate at which other areas of said film expand and soften. The different rates of expansion and softening produce multiple fractures in the metal coating between the selected areas and the other areas, whereby the fractures replicate the desired pattern.
权利要求：
THE CLAIMS DEFINING THE INVENTION ARE AS FOLLOWS:
1. A patterned metallized film comprising a transparent
or translucent polymeric film coated on one side with a thin
coating of metal, said metal coating and said polymeric film
being bonded to each other, and said metal coating having a
multiplicity of fractures of different sizes distributed
throughout the metal coating in a prescribed pattern so that
the reflection of light by the fractured metal coating
produces a three-dimensional illusion of said pattern when
viewed through said polymeric film.
2. The patterned metallized film of claim 1 which
S includes a layer of adhesive on the opposite side of said
metal coating from said polymeric film.
S.o. 3. The patterned metallized film of claim 2 wherein
0 said layer of adhesiveAfrom the group consisting of pressure-
sensitive adhesives, solvent-activatable adhesives, and heat-
activatable adhesives.
4. The patterned metallized film of claim 2 which
includes a paper backing sheet on the opposite side of said
adhesive layer from said metal coating.
The patterned metallized film of claim 1 wherein
said polymeric film is a flat film with smooth planar
surfaces, and said metal coating is applied to one of said
smooth planar surfaces with a substantially uniform thickness
over the entire surface.
6. The patterned metallized film of claim 1 which
includes a layer of adhesive on the opposite side of said
polymeric film from said metal coating.
7. The patterned metallized film of claim 1 wherein
said polymeric film has been non-uniformly expanded and
softened by heating said polymeric film in a preselected
pattern, and then cooling said polymeric film to room
temperature; and which includes a backing sheet, bonded to
said metal coating, which has been non-uniformly shrunk by
0. heating said backing sheet in said preselected pattern, said
fractures being of different sizes formed by the combination
of the non-uniform shrinkage of said backing sheet and the
«oooo non-uniform expansion and softening of said polymeric film.
8. A method of producing a patterned metallized film,
So said method comprising the steps of
0' metallizing a transparent or translucent polymeric film
on one side with a thin coating of reflective metal, and
producing a preselected pattern in said metal coating by
selectively fracturing said metal coating to produce a
multiplicity of fractures distributed throughout said metal
coating in accordance with said pattern.
9. The method of claim 8 wherein said metal coating
is selectively fractured by heating selected areas of said
metallized film at different rates, said selected areas
defining said pattern so that the resulting fractures are
distributed according to said pattern.
The method of claim 8 which includes the steps of
applying a layer of adhesive to said layer of metal and
covering said layer of adhesive with a release-treated
backing sheet.
11. The method of claim 8 which includes the steps of
applying a layer of adhesive to the opposite side of said
polymeric film from said metal coating, and covering said
15 layer of adhesive with a release-treated backing sheet.
'12. The method of claim 10 wherein said backing sheet
shrinks when heated.
20 13. The method of claim 12 wherein said metal coating
is selectively fractured by heating said polymeric film
after metallizing said film and after applying said layer
of adhesive and said backing sheet.
25 14. The method of claim 8, wherein said metal coating
is selectively fractured by passing said metallized film
through an apparatus comprising
a heated roll adapted to rotate in a first angular
direction; an!d
a patterned roll disposed radially adjacent said
i haated roll and adapted to counter-rotate with respect to
said heated roll in a second angular direction, said rolls
forming a nip therebetween for accepting said metallized
film and being disposed to apply a predetermined amount of
pressure to said metallized film as it passes through the
nip between said rolls.

The method of claim 8 wherein said preselected
pattern is produced by heating the metallized polymeric
film in said preselected pattern so that portions of the
metal-coated polymeri.c film are heated at a faster rate
than other portions, said portions that are heated at a
faster rate defining said preselected pattern.
16. A patterned metallized film substantially as
hereinbefore described with reference to the drawings
and/or Examples.
17. A method of producing a patterned metallized film
substantially as hereinbefore described with reference to
o r the drawings and/or Examples.
