<p>There is herein provided a composition for printing comprising an aqueous mixture having a room temperature curable latex polymer, a pigment, and a cure promoter, which when printed onto a substrate and dried, results in printing which retains a colorfastness above 3 when exposed to liquids with a pH between about 2 and about 13. The mixture may also contain a viscosity modifier. The mixture may be applied to a fabric as an aqueous mixture with a pre-cure pH adjusted to above 8 using a fugitive alkali and then cured at room temperature. Also provided is a printed substrate which may be a fabric of hydroentangled pulp and spunbond fibers, spunbond fabrics, meltblown fabrics, woven fabrics and laminates of spunbond and meltblown fabrics and having thereon the dried residue of the aqueous mixture described above and which retains a colorfastness above 3 when exposed to liquids with a pH between about 2 and about 13.</p> |
