Claim 5
Dependent Claim
88 words
A FILLER HAVING THE INK-ABSORBING AND FILM-FLATTENING PROPERTIES OF DIATOMACEOUS EARTH, UNIFORMLY DISPERSED THROUGHOUT THE RESINOUS ELASTOMER, THE SURFACE OF THE FILM HAVING LESS IRREGULARITIES THAN WOULD BE PRESENT WITHOUT THE FILLER, SAID FILLER COMPRISING ABOUT 5 TO 40 PARTS PER HUNDRED BY WEIGHT OF THE RESINOUS ELASTOMER, AND B. A WET, SLOW DRYING INK COATING ADHERED TO THE SURFACE OF SAID FILM ADAPTED TO FACE AWAY FROM THE PATTERN UPON LIGHT PRESSURE CONTACT, WITH A FINGER OR THE LIKE, OF SAID SURFACE WITH A PATTERN RECEIVING SURFACE.
Claim 6
Dependent Claim
88 words
A FILLER HAVING THE INK-ABSORBING AND FILM-FLATTENING PROPERTIES OF DIATOMACEOUS EARTH, UNIFORMLY DISPERSED THROUGHOUT THE RESINOUS ELASTOMER, THE SURFACE OF THE FILM HAVING LESS IRREGULARITIES THAN WOULD BE PRESENT WITHOUT THE FILLER, SAID FILLER COMPRISING ABOUT 5 TO 40 PARTS PER HUNDRED BY WEIGHT OF THE RESINOUS ELASTOMER, AND B. A WET, SLOW DRYING INK COATING ADHERED TO THE SURFACE OF SAID FILM ADAPTED TO FACE AWAY FROM THE PATTERN UPON LIGHT PRESSURE CONTACT, WITH A FINGER OR THE LIKE, OF SAID SURFACE WITH A PATTERN RECEIVING SURFACE.
Claim 7
Dependent Claim
88 words
a filler having the ink-absorbing and film-flattening properties of diatomaceous earth, uniformly dispersed throughout the resinous elastomer, the surface of the film having less irregularities than would be present without the filler, said filler comprising about 5 to 40 parts per hundred by weight of the resinous elastomer, and b. a wet, slow drying ink coating adhered to the surface of said film adapted to face away from the pattern upon light pressure contact, with a finger or the like, of said surface with a pattern receiving surface.
Claim 8
Dependent Claim
88 words
a filler having the ink-absorbing and film-flattening properties of diatomaceous earth, uniformly dispersed throughout the resinous elastomer, the surface of the film having less irregularities than would be present without the filler, said filler comprising about 5 to 40 parts per hundred by weight of the resinous elastomer, and b. a wet, slow drying ink coating adhered to the surface of said film adapted to face away from the pattern upon light pressure contact, with a finger or the like, of said surface with a pattern receiving surface.
Claim 9
Dependent Claim
12 words
The improvement according to claim 1 wherein the filler is diatomaceous arth.
Claim 10
Dependent Claim
12 words
The improvement according to claim 2 wherein the resinous elastomer is polyurethane.
Claim 11
Dependent Claim
20 words
The improvement according to claim 1, in which said film has a thickness of 0.00015 to 0.00025 of an inch.
Claim 12
Dependent Claim
27 words
The improvement according to claim 1 wherein said resin is polyurethane and in which said material contains 10 parts of diatomaceous earth per 100 parts of polyurethane.
Claim 13
Dependent Claim
22 words
The improvement according to claim 1 in which a marginal strip of the film is not coated with ink and is transparent.
