Abstract
Abstract A novel and useful ink jet recording transparency is described herein which is capable of wetting and absorbing colored, water soluble inks to provide permanent, high density images which are smear resistant. The transparency article of the invention includes a transparent resinous support which has a defined coating thereon. The coating is clear and consists essentially of a carboxylated, high molecular weight polymer or copolymer, or salts thereof, and, optionally, a pigment which is a particulate material. In the preferred embodiment of the invention, wherein high density images may be formed on a coated transparency from multiple jets of different colored inks which absorb such inks rapidly, the coating includes a carboxylated acrylic polymer which has been reacted with an organic amine.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
52 words
An ink jet recording transparency capable of being wetted by and absorbing colored, water soluble inks to provide high density images which are smear resistant comprising: (a) a substantially transparent resinous support, and (b) a substantially clear coating thereon which includes a carboxylated, high molecular weight polymer or copolymer, or salts thereof.
Claim 2
Dependent Claim
52 words
An ink jet recording transparency capable of being wetted by and absorbing colored, water soluble inks to provide high density images which are smear resistant comprising: (a) a substantially transparent resinous support, and (b) a substantially clear coating thereon which includes a carboxylated, high molecular weight polymer or copolymer, or salts thereof.
Claim 3
Dependent Claim
19 words
An ink jet recording transparency according to claim 1 in which said resinous support is a transparent polyester film.
Claim 4
Dependent Claim
35 words
An ink jet recording transparency according to claim 1 in which said carboxylated high molecular weight polymer is an acrylic or methacrylic polymer or copolymer having a molecular weight of from 50,000 to one million.
Claim 5
Dependent Claim
35 words
An ink jet recording transparency according to claim 1 which includes a pigment particulate material which is present in an amount such that the pigment to polymer ratio by weight is about 0.02 to 0.5.
Claim 6
Dependent Claim
22 words

Claim 7
Dependent Claim
20 words
An ink jet recording transparency according to claim 1 in which said coating has a thickness of about 2-15 microns.
Claim 8
Dependent Claim
24 words
An ink jet recording transparency according to claim 1 in which said coating contains a triethanolamine salt of a carboxylated acrylic polymer or copolymer.
Claim 9
Dependent Claim
55 words
An ink jet recording transparency according to claim 1 comprising: a transparent polyester film support, and a clear coating thereon consisting essentially of a carboxylated acrylic or methacrylic polymer or copolymer having a molecular weight of from 50,000 to 1 million, and amine salts thereof and the thickness of the coating is about 2-15 microns.
Claim 10
Dependent Claim
41 words
An ink jet recording transparency according to claim 8 which includes a pigment particulate material which is a synthetic silica having an average diameter of about 2-10 microns and in which the pigment to polymer ratio is about 0.02 to 0.5.
Claim 11
Dependent Claim
35 words
