Claims
- 1. A coated paper article in the form of a fibrous sheet coated on at least one surface with a paper-coating composition comprising a pigment, and an emulsion polymerized latex copolymer comprising (a) an ester of an ethylenically unsaturated carboxylic acid and a saturated alcohol, and (b) a hetero-unsaturated monomer selected from the group consisting of (1) an allyl acrylate or allyl methacrylate in an amount from about 0.05 to about 3.0 percent based on total monomer weight, or (2) a croytl acrylate or croytl methacrylate in an amount from about 0.20 to about 5.0 percent based on total monomer weight; said composition further characterized in that said pigment is present in an amount from about 99 to about 77 weight percent based on total dry solids.
- 2. An article as recited in claim 1 wherein said pigment is a mineral filler, a plastic filler or a mixture thereof.
- 3. An article as recited in claim 1 wherein (a) has a T.sub.g of greater than about 25.degree. C.
- 4. An article as recited in claim 1 wherein (a) is an ester of acrylic acid or methacrylic acid with a C.sub.1 or C.sub.9 saturated alcohol.
- 5. An article as recited in claim 1 wherein a major portion of (a) is an ester of acrylic acid or methacrylic acid with a C.sub.1 to C.sub.9 saturated alcohol, and a minor portion of (a) is an ester of acrylic acid or methacrylic acid with a C.sub.10 to C.sub.25 saturated alcohol.
- 6. An article as recited in claim 1 wherein said latex additionally comprises a monovinylidene aromatic monomer.
- 7. An article as recited in claim 1 wherein said latex additionally comprises an ethylenically unsaturated carboxylic acid.
- 8. An article as recited in claim 1 wherein (a) comprises a major portion of an ester of acrylic acid or methacrylic acid and a C.sub.1 to C.sub.9 saturation alcohol, and a minor proportion of an ester of acrylic acid or methacrylic acid and a C.sub.10 to C.sub.25 ; and the latex additionally comprises
- (1) an ethylenically unsaturated carboxylic acid; and
- (2) a monovinylidene aromatic monomer.
