Claims
- 1. A process for producing an alkaline paper which comprises adding a cationic starch solution consisting essentially of a member selected from the group consisting of an alkyltetrahydro-1,3,5-2H-thiadiazine-2-thione present in the cationic starch solution in amounts ranging from 100 to 3000 ppm based on the cationic starch solid matter and a bromonitroalcohol of the formula (1), ##STR2## where R.sub.1 and R.sub.2 are independently selected from the group consisting of hydrogen, methyl and ethyl, wherein said bromonitroalcohol is present in the cationic starch solution in amounts ranging from 5 to 50 ppm based on the cationic starch solid matter, and an alkylketene dimer to an alkaline paper stock making system.
- 2. The process according to claim 1 in which the amount of the cationic starch solution added ranges from 0.1 to 3.0% by weight based on the paper stock solid matter.
- 3. The process according to claim 1 in which the the cationic starch solution has a solid matter concentration of 5% or less.
- 4. The process according to claim 1 in which the the cationic starch solution has a solid matter concentration of 5% or less.
- 5. The process according to claim 1 in which the amount of the alkylketene dimer added to the cationic starch solution ranges from 0.05 to 0.5% by weight based on the paper stock solid matter.
- 6. The process according to claim 1 in which the pH of the paper making stock system is maintained within the range of 7 to 8.5.
- 7. The process according to claim 1, wherein the member is alkyltetrahydro -1,3,5-2H-thiadiazine-2-thione.
- 8. The process according to claim 1 wherein the member is a bromonitroalcohol of the formula (1), ##STR3## where R.sub.1 and R.sub.2 are independently selected from the group consisting of hydrogen, methyl and ethyl.
