Abstract
The present invention concerns a printing ink for a polyolefin polymer-based support, comprising at least a binder and at least a pigment, said binder being an oxidized polyolefin wax emulsified in water, said wax having a Brookfield viscosity less than 5000 mPa·s at 150° C. and acidity between 28 and 32 mg KOH/g, the viscosity of said ink being less than 2000 mPa·s at 25° C.

A printing ink for a polyolefin polymer-based support, comprising at least a binder and a pigment, said binder being an oxidized polyolefin wax emulsified in water, said wax having a Brookfield viscosity less than 5000 mPa·s at 150° C. and acidity between 28 and 32 mg KOH/g, the viscosity of said ink being less than 2000 mPa·s at 25° C.
A multilayer product comprising a polyolefin polymer-based support layer (1), and a polyolefin polymer-based wear layer (3), in which at least one face of said support layer (1) and/or said wear layer (3) is covered with an ink comprising at least a pigment and a binder, said binder being an oxidized polyolefin wax emulsified in water, said oxidized polyolefin wax having a Brookfield viscosity less than 5000 mPa·s at 150° C. and acidity between 28 and 32 mg KOH/g.
A method for manufacturing a multilayer product comprising a polyolefin polymer-based support layer (1) and a polyolefin polymer-based wear layer (3), said process comprising the following steps:
- Corona treatment of one face of said support layer (1) and/or said wear layer (3) to be printed.
- Application of an ink comprising at least a pigment and a binder to at least one face of said support layer (1) and/or wear layer (3), said binder being an oxidized polyolefin wax emulsified in water, said oxidized polyolefin wax having a Brookfield viscosity less than 5000 mPa·s at 150° C. and acidity between 28 and 32 mg KOH/g
- Drying of said ink
- Application of said wear layer (3) on said support layer (1).
- Assembly of said wear layer (3) to said support layer (1).
