Abstract
Abstract Windowed face plates are provided by applying to selected portions of the surface on one side of a transparent face plate a poorly adherent coating to provide easily strippable film portions lightly adhered to the plate, and then overcoating the same side of the plate with a heavily pigmented organic solventbased paint to form an opaque brittle film of paint which adheres strongly to the exposed surface of the plate and the strippable film portions to provide an opaque plate. An adhesive tape is then applied over a film portion which it is desired to remove and peeling off the adhesive tape causes the strippable film portion to be pulled off with the overlying paint attached thereto to thereby provide one or more windows in an opaque plate.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
148 words
A METHOD FOR THE PRODUCTION OF A WINDOWED FACE PLATE COMPRISING APPLYING TO SELECTED PORTIONS OF THE SURFACE ON ONE SIDE OF A TRANSPARENT FACE PLATE A POORLY ADHERENT COATING AND DRYING THE SAME TO PROVIDE EASILY STRIPPABLE FILM PORTIONS LIGHTLY ADHERED TO SAID PLATE, OVERCOATING THE SAME SIDE OF SAID PLATE WITH A HEAVILY PIGMENTED ORGANIC SOLVENT-BASED PAINT AND DRYING THE SAME TO FORM AN OPAQUE BRITTLE FILM OF PAINT WHICH ADHERES STRONGLY TI THE EXPOSED SURFACE OF SAID FACE PLATE ANS SAID STRIPPABLE FILM PORTIONS TO PROVIDE AN OPAQUE PLATE, APPLYING AN ADHESIVE TAPE TO THE PORTION OF SAID PAINT WHICH OVERLIES A FILM PORTION WHICH IT IS DESIRED TO REMOVE AND THEN PEELING OFF SAID ADHESIVE TAPE TO LIFT OFF THE PAINT OVERLYING SAID FILM PORTION TOGETHER WITH THE STRIPPABLE FILM PORTION ATTACHED THERETO TO THEREBY PROVIDE ONE OR MORE WINDOWS IN SAID OPAQUE PLATE.
Claim 2
Independent Claim

Claim 3
Dependent Claim
21 words
A method as recited in claim 1 in which an aqueous coating is applied to provide said easily strippable film portions.
Claim 4
Dependent Claim
16 words
A method as recited in claim 2 in which said aqueous coating is applied by printing.
Claim 5
Dependent Claim
24 words
A method as recited in claim 2 in which said organic solvent-based paint has a pigment to binder ratio of at least about 0.5:
Claim 6
Dependent Claim
18 words
A method as recited in claim 4 in which the pigment to binder ratio is at least 0.8:1.
Claim 7
Dependent Claim
47 words
A method as recited in claim 2 in which said aqueous coating contains a fatty acid soap which concentrates at the exposed surface of said strippable film portions To help maintain the integrity of said film portions against attack by the organic solvent in said solvent-based paint.
Claim 8
Dependent Claim
74 words
A method as recited in claim 1 in which a plurality of strippable film portions are adhered to said plate and overcoated by said brittle film of paint, and adhesive tapes are applied to and removed from the paint overlying some, but not all of said film portions, whereby one can bare fewer windows than there are strippable film portions without having the remaining potential window areas easily visible through the transparent face plate.
Claim 9
Independent Claim
162 words
A method for the production of a windowed face plate comprising applying by printing upon selected portions of the surface on one side of a transparent face plate a poorly adherent aqueous coating and drying the same to provide easily strippable film portions lightly adhered to said plate, overcoating the same side of said plate with a heavily pigmented organic solvent-based paint having a pigment to binder ratio of at least about 0.5:1 and drying the same to form an opaque brittle film of paint which adheres strongly to the exposed surface of said face plate and said strippable film portions to provide an opaque plate, applying an adhesive tape to the portion of said paint which overlies a film portion which it is desired to remove and then peeling off said adhesive tape to lift off the paint overlying said film portion together with the strippable film portion attached thereto to thereby provide one or more windows in said opaque plate.
Claim 10
Independent Claim
162 words
A method for the production of a windowed face plate comprising applying by printing upon selected portions of the surface on one side of a transparent face plate a poorly adherent aqueous coating and drying the same to provide easily strippable film portions lightly adhered to said plate, overcoating the same side of said plate with a heavily pigmented organic solvent-based paint having a pigment to binder ratio of at least about 0.5:1 and drying the same to form an opaque brittle film of paint which adheres strongly to the exposed surface of said face plate and said strippable film portions to provide an opaque plate, applying an adhesive tape to the portion of said paint which overlies a film portion which it is desired to remove and then peeling off said adhesive tape to lift off the paint overlying said film portion together with the strippable film portion attached thereto to thereby provide one or more windows in said opaque plate.
Claim 11
Dependent Claim
91 words
A windowed face plate stock material comprising a transparent face plate having selected separated portions of one side thereof lightly adhered to a plurality of easily strippable film portions constituted by dried coatings said one side of said face plate being overcoated with a heavily pigmented opaque film of brittle paint strongly adhered to the exposed surface of said face plate and said strippable film portions, the portions of said film of brittle paint overlying said strippable film portions being easily strippable from said face plate with said strippable film portions.
Claim 12
Dependent Claim
91 words
A windowed face plate stock material comprising a transparent face plate having selected separated portions of one side thereof lightly adhered to a plurality of easily strippable film portions constituted by dried coatings said one side of said face plate being overcoated with a heavily pigmented opaque film of brittle paint strongly adhered to the exposed surface of said face plate and said strippable film portions, the portions of said film of brittle paint overlying said strippable film portions being easily strippable from said face plate with said strippable film portions.
