Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
64 words
A dried, coated paper web for finishing by calender means to produce high-gloss coated paper which comprises a paper web coated on at least one side with a paper coating pigment and sufficient binder to bind the pigment when the binder has been coalesced, said binder consisting essentially of a hard thermoplastic polymer which is substantially uncoalesced and thereby the pigment unbonded and moldable.
Claim 2
Dependent Claim
64 words
A dried, coated paper web for finishing by calender means to produce high-gloss coated paper which comprises a paper web coated on at least one side with a paper coating pigment and sufficient binder to bind the pigment when the binder has been coalesced, said binder consisting essentially of a hard thermoplastic polymer which is substantially uncoalesced and thereby the pigment unbonded and moldable.
Claim 3
Dependent Claim
25 words
The coated paper web according to claim 1 wherein the hard polymer has a hardness/temperature relationship as represented by the curve shown in FIG. 1.
Claim 4
Dependent Claim
25 words
The coated paper web according to claim 1 wherein the hard polymer is selected from the group consisting of vinyl acetate, styrene-isoprene and acrylic polymers.
Claim 5
Dependent Claim
21 words
The coated paper web according to claim 1 wherein the hard polymer has a glass transition temperature greater than 100° F.
Claim 6
Independent Claim
52 words
A method of producing a dried, coated paper web for finishing by calender means to produce high-gloss coated paper which comprises a paper web coated on at least one side with a paper coating pigment and a binder, said binder consisting essentially of a hard thermoplastic polymer which is substantially uncoalesced, comprising:
Claim 7
Independent Claim
52 words
A method of producing a dried, coated paper web for finishing by calender means to produce high-gloss coated paper which comprises a paper web coated on at least one side with a paper coating pigment and a binder, said binder consisting essentially of a hard thermoplastic polymer which is substantially uncoalesced, comprising:
Claim 8
Dependent Claim
60 words
Applying to the surface of at least on side of the paper web an aqueous composition comprising the pigment and a sufficient quantity of the binder to bind the pigment when the binder has been coalesced, and 2. Drying the coating at a temperature below which substantial coalescence of the binder occurs to thereby leave the pigment unbound and moldable.
Claim 9
Dependent Claim
60 words
Applying to the surface of at least on side of the paper web an aqueous composition comprising the pigment and a sufficient quantity of the binder to bind the pigment when the binder has been coalesced, and 2. Drying the coating at a temperature below which substantial coalescence of the binder occurs to thereby leave the pigment unbound and moldable.
Claim 10
Dependent Claim
29 words
The coated paper web according to claim 1, wherein the amount of binder which is not hard, thermoplastic polymer is less than 5% based on 100 parts of pigment.
