ABSTRACT:
A stencil printing ink is described, comprising 0.5 to 20% by weight pigment, 5 to 30% by weight extender pigment, 0.5 to 5% by weight water-soluble polymer (the viscosity of its 10% aqueous solution is at least 40 cps), 3 to 15% by weight (calculated as solids) o/w type resin emulsion, 5 to 20% by weight polyhydric alcohol and water. This ink can produce printed images without being affected by printing conditions such as temperature and application pressure. Thus, it is suitably used in stencil printing for non-professional or unskilled people.
