Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
49 words
IMPROVED MATTE SHEET MATERIAL CAPABLE OF RECEIVING INK MARKINGS COMPRISING A POLYESTER FILM BASE AT LEAST ONE SURFACE OF WHICH CARRIERS A FIRST LAYER OF CELLULOSIC MATTE FILM-FORMING LACQUER COMPOSITION, THE SURFACE OF SAID FIRST LAYER CARRYING A SECOND LAYER COMPRISING AN ALKYL MONOESTER OF POLY(ALKYL VINYL ETHER-MALEIC ACID).
Claim 2
Dependent Claim
49 words
IMPROVED MATTE SHEET MATERIAL CAPABLE OF RECEIVING INK MARKINGS COMPRISING A POLYESTER FILM BASE AT LEAST ONE SURFACE OF WHICH CARRIERS A FIRST LAYER OF CELLULOSIC MATTE FILM-FORMING LACQUER COMPOSITION, THE SURFACE OF SAID FIRST LAYER CARRYING A SECOND LAYER COMPRISING AN ALKYL MONOESTER OF POLY(ALKYL VINYL ETHER-MALEIC ACID).
Claim 3
Dependent Claim
49 words
Improved matte sheet material capable of receiving ink markings comprising a polyester film base at least one surface of which carries a first layer of cellulosic matte film-forming lacquer composition, the surface of said first layer carrying a second layer comprising an alkyl monoester of poly(alkyl vinyl ether-maleic acid).
Claim 4
Dependent Claim
49 words
Improved matte sheet material capable of receiving ink markings comprising a polyester film base at least one surface of which carries a first layer of cellulosic matte film-forming lacquer composition, the surface of said first layer carrying a second layer comprising an alkyl monoester of poly(alkyl vinyl ether-maleic acid).
Claim 5
Dependent Claim
51 words
The matte sheet material of claim 1 produced by coating at least one surface of a polyester film base with a first layer of cellulosic matte film-forming lacquer composition and thereafter overcoating said first layer with a coating comprising a solvent solution of an alkyl monoester of poly(alkyl vinyl ether-maleic acid).
Claim 6
Dependent Claim
33 words
The matte sheet material of claim 2 wherein the alkyl monoester of poly(alkyl vinyl ether-maleic acid) is applied from a solvent solution containing from about 0.5 to about 10.0 percent of said monoester.
Claim 7
Dependent Claim
34 words
The matte sheet material of claim 2 wherein the solvent solution is applied to the cellulosic matte lacquer coated film base in the range of about 0.3 to about 15.0 grams per square meter.
Claim 8
Dependent Claim
25 words
The matte sheet material of claim 1 wherein the alkyl monoester of poly(alkyl vinyl ether-maleic acid) is the ethyl monoester of poly(methyl vinyl ether-maleic acid).
Claim 9
Dependent Claim
25 words
The matte sheet material of claim 1 wherein the alkyl monoester of poly(alkyl vinyl ether-maleic acid) is the isopropyl monoester of poly(methyl vinyl ether-maleic acid).
Claim 10
Dependent Claim
25 words
The matte sheet material of claim 1 wherein the alkyl monoester of poly(alkyl vinyl ether-maleic acid) is the butyl monoester of poly(methyl vinyl ether-maleic acid).
Claim 11
Dependent Claim
22 words
The matte sheet material of claim 1 wherein the alkyl group of the alkyl monoester component contains 1 to 7 carbon atoms.
