Abstract: A latex marking ink suitable for marking rubber articles has been developed. The ink comprises vulcanizable rubber latex, pigment, vulcanizing agent, and non-ionic stabilizer dispersed in water. Shear stability is dramatically and unexpectedly increased by the presence of the non-ionic stabilizer even though viscosity also increases.
