Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
50 words
AN ELECTRIC CURRENT RESPONSIVE SHEET COMPRISING AN ELECTRICALLY CONDUCTING FLEXIBLE BASE AND A THIN COATING BETWEEN .001 AND.01 INCH THICK WHEN WET ON THE FLEXIBLE BASE, SAID COATING BEING A SLIGHTLY WATER PERMEABLE BUT NOT WATER SOLUBLE, POLYMER SELECTED FROM THE GROUP CONSISTING OF CELLULOSE ACETATE PHTHALATE AND POLY(METHYLMETHACRYLATE-METHACRYLIC ACID).
Claim 2
Dependent Claim
50 words
AN ELECTRIC CURRENT RESPONSIVE SHEET COMPRISING AN ELECTRICALLY CONDUCTING FLEXIBLE BASE AND A THIN COATING BETWEEN .001 AND.01 INCH THICK WHEN WET ON THE FLEXIBLE BASE, SAID COATING BEING A SLIGHTLY WATER PERMEABLE BUT NOT WATER SOLUBLE, POLYMER SELECTED FROM THE GROUP CONSISTING OF CELLULOSE ACETATE PHTHALATE AND POLY(METHYLMETHACRYLATE-METHACRYLIC ACID).
Claim 3
Independent Claim
90 words
A METHOD OF RECORDING AN IMAGE WHICH COMPRISES CREATING A PATTERN OF ELECTRIC CURRENT CORRESPONDING TO SAID IMAGE, PASSING SAID CURRENT THROUGH AN ELECTRICALLY CONDUCTING LAYER OF A SLIGHTLY WATER PERMEABLE BUT NOT WATER SOLUBLE POLYMER SELECTED FROM THE GROUP CONSISTING OF CELLULOSE ACETATE PHTHALATE AND POLY(METHYLMETHACRYLATEMETHACRYLIC ACID), TO INCREASE IN ACCORDANCE WITH SAID PATTERN THE SOLUBILITY OF THE LAYER IN WATER, AND IN THE PRESENCE OF WATER IN THE LAYER, FORMING A RECORD IN ACCORDANCE WITH THE DIFFERENCES IN SOLUBILITY OF THE LAYER CAUSED BY THE PASSAGE OF CURRENT.
Claim 4
Independent Claim
90 words
A METHOD OF RECORDING AN IMAGE WHICH COMPRISES CREATING A PATTERN OF ELECTRIC CURRENT CORRESPONDING TO SAID IMAGE, PASSING SAID CURRENT THROUGH AN ELECTRICALLY CONDUCTING LAYER OF A SLIGHTLY WATER PERMEABLE BUT NOT WATER SOLUBLE POLYMER SELECTED FROM THE GROUP CONSISTING OF CELLULOSE ACETATE PHTHALATE AND POLY(METHYLMETHACRYLATEMETHACRYLIC ACID), TO INCREASE IN ACCORDANCE WITH SAID PATTERN THE SOLUBILITY OF THE LAYER IN WATER, AND IN THE PRESENCE OF WATER IN THE LAYER, FORMING A RECORD IN ACCORDANCE WITH THE DIFFERENCES IN SOLUBILITY OF THE LAYER CAUSED BY THE PASSAGE OF CURRENT.
Claim 5
Dependent Claim
31 words
THE METHOD ACCORDING TO CLAIM 4 IN WHICH SAID FORMING A RECORD CONSISTS OF APPLYING TO AND TRANSFERRING FROM THE MORE SOLUBLE AREAS OF THE RECORD, AN AQUEOUS SOLUTION OF DYE.
