Abstract
Abstract A multi-ply mailer and method of making wherein the top sheet has a CB coating, the next adjacent intermediate ply has a CF coating and the top sheet has a localized area coated with transparentizing material with image developing properties whereby impressing the localized area results in the development of an image visible through the top ply.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
116 words
A multi-ply mailer form having an envelope front and an envelope back comprising a plurality of sheets in superposed relationship wherein the top sheet constitutes the mailer envelope front, said top sheet having an outer and inner surface, a CB coating extending substantially entirely over said inner surface, the sheet of said multi-ply form adjacent said top sheet having a CF coating extending substantially entirely over the surface of said adjacent sheet confronting said top sheet inner surface, said top sheet inner surface having a localized area coating of a transparentizing material containing CB capsules whereby impressing said localized area results in the development of an image on said confronting surface visible through said top sheet.
Claim 2
Dependent Claim
116 words
A multi-ply mailer form having an envelope front and an envelope back comprising a plurality of sheets in superposed relationship wherein the top sheet constitutes the mailer envelope front, said top sheet having an outer and inner surface, a CB coating extending substantially entirely over said inner surface, the sheet of said multi-ply form adjacent said top sheet having a CF coating extending substantially entirely over the surface of said adjacent sheet confronting said top sheet inner surface, said top sheet inner surface having a localized area coating of a transparentizing material containing CB capsules whereby impressing said localized area results in the development of an image on said confronting surface visible through said top sheet.
Claim 3
Dependent Claim
15 words
The form of claim 1 in which said transparentizing material contains about 30% CB capsules.
Claim 4
Dependent Claim
22 words
The form of claim 1 in which said transparentizing material includes a member selected from the class consisting of wax and oil.
Claim 5
Dependent Claim
34 words
The form of claim 1 in which said coating of transparentizing material is slightly tacky to adhere said localized area to said confronting surface during mail processing but insufficient to inhibit easy ply separation.
Claim 6
Independent Claim
101 words
A method of producing a multi-ply mailer form having an envelope front and an envelope back, comprising superposing a plurality of sheets, one of said sheets being an outer sheet to constitute the mailer envelope front and having outer and inner surfaces, prior to said superposing, applying a CB coating over substantially the entire inner surface of said outer sheet, and also prior to said superposing applying a transparentizing material containing CB capsules to a localized area of said top sheet inner surface, and applying a CF coating substantially over the entire confronting surface of the sheet adjacent said outer sheet.
Claim 7
Independent Claim
101 words
A method of producing a multi-ply mailer form having an envelope front and an envelope back, comprising superposing a plurality of sheets, one of said sheets being an outer sheet to constitute the mailer envelope front and having outer and inner surfaces, prior to said superposing, applying a CB coating over substantially the entire inner surface of said outer sheet, and also prior to said superposing applying a transparentizing material containing CB capsules to a localized area of said top sheet inner surface, and applying a CF coating substantially over the entire confronting surface of the sheet adjacent said outer sheet.
Claim 8
Dependent Claim
23 words
The method of claim 5 in which said transparentizing material includes about 70% of a wax-like material and about 30% of CB capsules.
Claim 9
Dependent Claim
28 words
The method of claim 5 in which heat and pressure area applied to said localized area incident to application of said transparentizing material to impregnate said outer sheet.
Claim 10
Dependent Claim
34 words
The method of claim 7 in which said pressure is from about 5 to about 20 psi and said heat is sufficient to elevate the temperature of said transparentizing material above about 160° F.
Claim 11
Dependent Claim
27 words
The method of claim 5 in which said transparentizing material is from about 2 to about 5 times the amount per unit area of said CB coating.
Claim 12
Independent Claim
130 words
A method of producing a multi-ply mailer form having an envelope front and an envelope back comprising superposing a plurality of sheets, one of said sheets being an outer sheet to constitute the mailer envelope front and having outer and inner surfaces, prior to said superposing, applying a CB coating over substantially the entire surface of said outer sheet, and also prior to said superposing applying a transparentizing material containing CB capsules to a localized area of said top sheet inner surface, and applying a CF coating substantially over the entire confronting surface of the sheet adjacent said outer sheet an adhesive material being incorporated into said transparentizing coating to render the same slightly tacky, said adhesive constituting from about 2% to about 15% by weight of said transparentizing material.
Claim 13
Independent Claim
130 words
A method of producing a multi-ply mailer form having an envelope front and an envelope back comprising superposing a plurality of sheets, one of said sheets being an outer sheet to constitute the mailer envelope front and having outer and inner surfaces, prior to said superposing, applying a CB coating over substantially the entire surface of said outer sheet, and also prior to said superposing applying a transparentizing material containing CB capsules to a localized area of said top sheet inner surface, and applying a CF coating substantially over the entire confronting surface of the sheet adjacent said outer sheet an adhesive material being incorporated into said transparentizing coating to render the same slightly tacky, said adhesive constituting from about 2% to about 15% by weight of said transparentizing material.
