Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
19 words
A composition as defined in claim 1 wherein the copolymer contains copolymerized therein an aminoalkyl vinyl ether or sulfide.
Claim 2
Dependent Claim
18 words
A composition as defined in claim 1 wherein the copolymer contains copolymerized therein an aminoalkyl acrylate or methacrylate.
Claim 3
Dependent Claim
152 words
A composition as defined in claim 1 wherein the copolymer contains copolymerized therein an oxazolidine of the formula wherein m is an integer having a value of 2 to 3, R'', when not directly joined to R2, is selected from the group consisting of hydrogen, phenyl, benzyl, and (C1-C12) alkyl groups, R2, when not directly joined to R'', is selected from the group consisting of hydrogen and (C1-C4) alkyl groups, R'' and R2, when directly joined together, form a 5- to 6-carbon ring with the attached carbon atom of the ring in the formula, i.e., R'' and R2, when joined together, are selected from the group consisting of pentamethylene and tetramethylene, and A'' is -O(CH2)m- or (O-alkylene)n- in which (O-alkylene)n is a poly(oxyalkylene) group, having a molecular weight in the range from 88 to 348, in which the individual alkylene radicals are the same or different and are either ethylene or propylene.
Claim 4
Dependent Claim
21 words
A composition as defined in claim 1 wherein the copolymer contains copolymerized therein a compound of one of the following formulas:
Claim 5
Dependent Claim
28 words
A composition as defined in claim 1 wherein the copolymer is a copolymer of at least one ester of acrylic acid or methacrylic acid and an amine-containing monomer.
Claim 6
Dependent Claim
29 words
A composition as defined in claim 1 wherein the copolymer is a copolymer of acrylonitrile, at least one ester of acrylic acid or methacrylic acid and an amine-containing monomer.
Claim 7
Dependent Claim

Dependent Claim
16 words
A composition as defined in claim 10 wherein the binder contains only components (a) and (b).
Claim 11
Dependent Claim
27 words
A composition as defined in claim 4 wherein the copolymer is a copolymer of at least one ester of acrylic acid or methacrylic acid and the oxazolidine.
Claim 12
Dependent Claim
26 words
A composition as defined in claim 1 wherein the component (c) is present in an amount less than 30 weight percent of the amount of (b).
Claim 13
Dependent Claim
30 words
A mineral-coated paper product in which a paper sheet carries on a surface thereof a coating formed of a dried deposit of a coating composition as defined in claim 1.
Claim 14
Dependent Claim
30 words
A mineral-coated paper product in which a paper sheet carries on a surface thereof a coating formed of a dried deposit of a coating composition as defined in claim 6.
