Abstract
Abstract A multi-ply business form comprising a plurality of sheets in superposed relationship wherein the top sheet comprises a support bearing a localized coating comprising both microscopic pressure rupturable capsules containing a chromogenic material, and an electron acceptor material. At least one underlying sheet can comprise a support bearing a second localized autogenous coating comprising chromogen-containing microscopic pressure rupturable capsules and an electron acceptor material on its upper surface wherein the localized autogenous coatings are non-coextensive.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
78 words
A multi-ply mailer form, comprising a plurality of sheets in superposed relationship, wherein the top sheet comprises a support bearing a localized autogenous coating comprising an admixture of electron-acceptor material and chromogen-containing microscopic pressure-rupturable capsules, said localized autogenous coating being capable of reacting under the impact of a printing stylus to release said chromogen from said capsules for reaction with said electron acceptor material in said autogenous coating without transfer to provide a visible image comprising address information.
Claim 2
Dependent Claim
78 words
A multi-ply mailer form, comprising a plurality of sheets in superposed relationship, wherein the top sheet comprises a support bearing a localized autogenous coating comprising an admixture of electron-acceptor material and chromogen-containing microscopic pressure-rupturable capsules, said localized autogenous coating being capable of reacting under the impact of a printing stylus to release said chromogen from said capsules for reaction with said electron acceptor material in said autogenous coating without transfer to provide a visible image comprising address information.
Claim 3
Dependent Claim
45 words
The form of claim 1 wherein at least one underlying sheet comprises a support bearing a second localized autogenous coating comprising both chromogen-containing microscopic pressure rupturable capsules and an electron acceptor material on its upper surface, said first and second localized autogenous coatings being non-coextensive.
Claim 4
Dependent Claim
19 words
The form of claim 2 wherein said form comprises a zig-zag folded stack of a plurality of elongated plies.
Claim 5
Dependent Claim
39 words
The form of claim 1 wherein at least one underlying sheet comprises a support bearing a localized coating of a transfer medium on its backside, said first localized coating and said localized coating containing said transfer medium being non-coextensive.
Claim 6
Dependent Claim
15 words
The form of claim 1 wherein the backside of said support bears a transfer coating.
Claim 7
Dependent Claim
15 words
The form of claim 1 wherein said electron acceptor material is an alkylphenol-formaldehyde novolac resin.
Claim 8
Dependent Claim
102 words
A printing system for producing printed multi-ply mailer forms consisting essentially of (a) a printing stylus for producing a visible image upon impact, (b) a multi-ply mailer form comprising a plurality of sheets in superposed relationship, wherein the top sheet comprises a support being a localized autogenous coating comprising an admixture of an electron acceptor material and microscopic pressure-rupturable capsules on its upper surface, said stylus forming a visible image upon impact with said localized autogenous coating by rupturing said capsules to release said chromogen from said capsules for reaction with said electron acceptor material in said localized autogenous coating without transfer.
Claim 9
Dependent Claim
102 words
A printing system for producing printed multi-ply mailer forms consisting essentially of (a) a printing stylus for producing a visible image upon impact, (b) a multi-ply mailer form comprising a plurality of sheets in superposed relationship, wherein the top sheet comprises a support being a localized autogenous coating comprising an admixture of an electron acceptor material and microscopic pressure-rupturable capsules on its upper surface, said stylus forming a visible image upon impact with said localized autogenous coating by rupturing said capsules to release said chromogen from said capsules for reaction with said electron acceptor material in said localized autogenous coating without transfer.
Claim 10
Dependent Claim
31 words
The printing system of claim 7 wherein a non-reactive shielding means is interposed between said stylus and said autogenous coating to reduce the impact of said stylus upon said autogenous coating.
Claim 11
Dependent Claim
16 words
The printing system of claim 7 wherein the backside of said support bears a transfer coating.
Claim 12
Dependent Claim
17 words
The printing system of claim 7 wherein said printing stylus is a component of a computer printer.
Claim 13
Dependent Claim
15 words
The printing system of claim 7 wherein said electron acceptor is an alkylphenol-formaldehyde novolac resin.
Claim 14
Independent Claim
103 words
A method for forming non-coextensive, visible images in a multi-ply mailer form which comprises contacting the top sheet of a multiple mailer form comprising a plurality of sheets in superposed relationship, wherein the top sheet comprises a support bearing a localized autogenous coating comprising an electron acceptor material and microscopic pressure-rupturable capsules containing a chromogenic material on its upper surface, with the printing stylus from an impact printer thereby providing a visible image in said localized, autogenous coating by rupturing said capsules to release said chromogen from said capsules for reaction with said electron acceptor material in said localized autogenous coating without transfer.
Claim 15
Independent Claim
103 words
A method for forming non-coextensive, visible images in a multi-ply mailer form which comprises contacting the top sheet of a multiple mailer form comprising a plurality of sheets in superposed relationship, wherein the top sheet comprises a support bearing a localized autogenous coating comprising an electron acceptor material and microscopic pressure-rupturable capsules containing a chromogenic material on its upper surface, with the printing stylus from an impact printer thereby providing a visible image in said localized, autogenous coating by rupturing said capsules to release said chromogen from said capsules for reaction with said electron acceptor material in said localized autogenous coating without transfer.
Claim 16
Dependent Claim
14 words
