Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
A carbonless copying system having a recording substrate, first and second mark-forming components capable of reacting with each other to produce a colored reaction product, and a first type of microcapsule having generally continuous walls encapsulating a first fill material, the first fill material comprising a solution or suspension containing the first mark-forming component, characterised in that there is provided a second type of microcapsule having generally continuous walls encapsulating a second fill material, the second fill material consisting of solvent capable of dissolving either the first or the second mark-forming component or both wherein the first and the second type of microcapsule and the second mark-forming component being arranged in juxtaposed pressure-sensitive contact with respect to one another such that the application of marking pressure upon the carbonless system causes a colored mark to form on the recording substrate.
Claim 2
Dependent Claim
140 words
A carbonless copying system having a recording substrate, first and second mark-forming components capable of reacting with each other to produce a colored reaction product, and a first type of microcapsule having generally continuous walls encapsulating a first fill material, the first fill material comprising a solution or suspension containing the first mark-forming component, characterised in that there is provided a second type of microcapsule having generally continuous walls encapsulating a second fill material, the second fill material consisting of solvent capable of dissolving either the first or the second mark-forming component or both wherein the first and the second type of microcapsule and the second mark-forming component being arranged in juxtaposed pressure-sensitive contact with respect to one another such that the application of marking pressure upon the carbonless system causes a colored mark to form on the recording substrate.
Claim 3
Dependent Claim
33 words
The carbonless copying system as claimed in Claim 1 characterised in that the first mark-forming component is a colorless dye precursor and the second mark-forming component is an acidic clay or phenolic resin.
Claim 4
Dependent Claim
29 words
The carbonless copying system as claimed in Claim 1 or 2 characterised in that the second fill material is an organic solvent capable of dissolving the colorless dye precursor.
Claim 5
Dependent Claim
37 words
The carbonless copying system as claimed in Claim 1, 2 or 3 characterised in that the second type of microcapsule and the second mark forming component are coated over at least a portion of the recording substrate.
Claim 6
Dependent Claim
36 words
The carbonless copying system as claimed in any one of the preceding Claims which additionally comprises a transfer substrate wherein the first type of microcapsule is coated over at least a portion of the transfer substrate.
Claim 7
Dependent Claim
44 words
The carbonless copying system as claimed in any one of Claims 1 to 3 which additionally comprises a transfer substrate wherein the second type of microcapsule and the first type of microcapsule are both coated over at least a portion of the transfer substrate.
