Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
53 words
IN A RECORDING PROCESS IN WHICH AN AMINE IS IMAGEWISE RELEASED FROM AN AMINE SOURCE CARRIED IN EFFECTIVE AMOUNT ON A SUPPORT AND INCLUDING THE STEP IF IMAGEWISE EXPOSING SAID SUPPORT TO ACTIVATING RADIATION THE IMPROVEMENT WHEREIN SAID AMINE SOURCE IS A THERMO- OR PHOTOSENSITIVE AMINE PROGENITOR CORRESPONDING TO THE FOLLOWING GENERAL FORMULA:
Claim 2
Dependent Claim

IN A RECORDING PROCESS IN WHICH AN AMINE IS IMAGEWISE RELEASED FROM AN AMINE SOURCE CARRIED IN EFFECTIVE AMOUNT ON A SUPPORT AND INCLUDING THE STEP IF IMAGEWISE EXPOSING SAID SUPPORT TO ACTIVATING RADIATION THE IMPROVEMENT WHEREIN SAID AMINE SOURCE IS A THERMO- OR PHOTOSENSITIVE AMINE PROGENITOR CORRESPONDING TO THE FOLLOWING GENERAL FORMULA:
Claim 3
Dependent Claim
20 words
A process according to claim 1, wherein said amine progenitor releases a polyfunctional amine capable of acting as cross-linking agent.
Claim 4
Dependent Claim
24 words
A process according to claim 1, wherein said amine progenitor upon exposure releases an aromatic amine capable of taking part in a dye-forming reaction.
Claim 5
Dependent Claim
17 words
A process according to claim 1, wherein said amine progenitor upon exposure releases a high pH amine.
Claim 6
Dependent Claim
21 words
A process according to claim 1, wherein said amine progenitor upon exposure releases an amine capable of catalyzing a dye-forming reaction.
Claim 7
Dependent Claim
23 words
A process according to claim 3, wherein the dyeforming reaction takes place by means of an oxidizing agent incorporated in the recording material.
Claim 8
Dependent Claim
13 words
A process according to claim 6, wherein the oxidizing agent is m-chloroperbenzoic acid.
Claim 9
Dependent Claim
34 words
A process according to claim 6, wherein a mixture of said amine progenitor, an oxidizing agent and a color coupler reactive with said released amine to form a dye is present on said support.
Claim 10
Dependent Claim
40 words
A process according to claim 1, wherein said amine progenitor upon exposure step release a p-phenylenediamine derivative, which is capable of producing an indophenol or azamethine dye by oxidative coupling with a phenol, naphthol or active methylene type colour coupler.
Claim 11
Dependent Claim
42 words
A recording material comprising a support having thereon a layer of a film forming binding agent containing an effective amount of a photosensitive and/or thermosensitive amine progenitor releasing an amine upon exposure to activating radiation and corresponding to the following general formula:
Claim 12
Dependent Claim
42 words
A recording material comprising a support having thereon a layer of a film forming binding agent containing an effective amount of a photosensitive and/or thermosensitive amine progenitor releasing an amine upon exposure to activating radiation and corresponding to the following general formula:
Claim 13
Dependent Claim
42 words
A recording material according to claim 10, wherein R1 represents an alkyl group or a phenyl group, R2 represents an alkyl group, R3 represents hydrogen or R2 and R3 form together part of a piperidine or morpholine ring and R4 represents hydrogen.
Claim 14
Dependent Claim
32 words
A recording material according to claim 10, wherein said amine progenitor is present in admixture with a phenol, naphthol and/or active methylene type coupler capable of oxidative coupling with the released amine.
Claim 15
Dependent Claim
22 words
A recording material according to claim 10 wherein said progenitor and binding agent are present in a weight ratio of 1: 5-1:50.
Claim 16
Dependent Claim
15 words
A recording material according to claim 12 wherein said admixture also contains an oxidizing agent.
Claim 17
Dependent Claim
14 words
A recording material according to claim 14, wherein the oxidizing agent is m-chloroperbenzoic acid.
