Abstract
The present invention provides a process for preparing printed shrinkable polymeric film substrates, by applying an ink or overprint varnish comprising self-crosslinking acrylic emulsions. The inks and overprint varnishes are rub, scratch, chemical, humidity/water, and heat resistant, as well as being resistant to repeated bending and folding.
Claims40
A process for printing on a polymeric substrate, comprising:
- a) providing an ink or coating composition comprising:

- ii) at least one coalescent;
- iii) at least one silicone emulsion;
- and
- iv) water;
- wherein the self-crosslinking acrylic polymer has a glass transition temperature of greater than 0° C.;
- b) applying the ink or coating composition of a) to a polymeric substrate;
- and
- c) drying the ink or coating composition on the polymeric substrate.
