Abstract
A saturated paper suitable for use in a clean room environment, which paper includes a fibrous web in which at least about 50 percent of the fibers comprising the web, on a dry weight basis, are cellulosic fibers. The paper also includes a saturant which is present in the saturated paper at a level of from about 10 to about 100 percent, based on the dry weight of the fibrous web. The saturant, in turn, includes from about 98 to about 70 percent, on a dry weight basis, of a latex reinforcing polymer having a glass transition temperature of from about -40.degree. C. to about 25.degree. C.; and from about 2 to about 30 percent, on a dry weight basis, of a cationic polymer. The saturant is adapted to render the saturated paper durable, low linting, and ink jet printable.
Claims20
A saturated paper comprising:
- a fibrous web in which at least about 50 percent of the fibers comprising the web, on a dry weight basis, are cellulosic fibers;
- and
- a saturant which is present in the saturated paper at a level of from about 10 to about 100 percent, based on the dry weight of the fibrous web;
- in which the saturant comprises:
- from about 98 to about 70 percent, on a dry weight basis, of a nonionic or cationic latex reinforcing polymer having a glass transition temperature of from about -40.degree. C. to about 25.degree. C.;
- and
- from about 2 to about 30 percent, on a dry weight basis, of a cationic polymer;
- wherein the saturant is adapted to render the saturated paper durable, low linting, and ink jet printable.
A saturated paper comprising:
- a fibrous web in which at least about 50 percent of the fibers comprising the web, on a dry weight basis, are cellulosic fibers;
- and
- a saturant which is present in the saturated paper at a level of from about 20 to about 70 percent, based on the dry weight of the fibrous web;
- in which the saturant comprises:
- from about 96 to about 80 percent, on a dry weight basis, of a nonionic or cationic latex reinforcing polymer having a glass transition temperature of from about -15.degree. C. to about 15.degree. C.;
- and
- from about 4 to about 20 percent, on a dry weight basis, of a cationic polymer;
- wherein the saturant is adapted to render the saturated paper durable, low linting, and ink jet printable.
A saturated paper comprising:
- a fibrous web in which substantially all of the fibers comprising the web are cellulosic fibers;
- and
- a saturant which is present in the saturated paper at a level of from about 20 to about 70 percent, based on the dry weight of the fibrous web;
- in which the saturant comprises:
- from about 96 to about 80 percent, on a dry weight basis, of a nonionic or cationic latex reinforcing polymer having a glass trainsition temperature of from about -15.degree. C. to about 15.degree. C.;
- and
- from about 4 to about 20 percent, on a dry weight basis, of a cationic polymer;
- wherein the saturant is adapted to render the saturated paper durable, low linting, and ink jet printable.
