Abstract

This invention relates to an inkjet ink comprising: a non-redispersible aqueous polyurethane (meth)acrylate dispersion; a polyoxyalkylene alkyl/alkenyl ether surfactant; and a water-dispersible or water-soluble photoinitiator. The ink has improved redispersibility in water after thermal drying and before curing.

Claims (15)

Claims
1. An inkjet ink comprising: a non-redispersible aqueous polyurethane (meth)acrylate dispersion; a polyoxyalkylene alkyl/alkenyl ether surfactant; and a water-dispersible or water-soluble photoinitiator.
2. An inkjet ink as claimed in claim 1 , wherein the ink further comprises an inorganic silicate.
3. An inkjet ink as claimed in claim 2, wherein the inorganic silicate is selected from colloidal silica or an alkali metal, preferably colloidal silica.
4. An inkjet ink as claimed in any one of claims 1 to 3, wherein the polyoxyalkylene alkyl/alkenyl ether surfactant is present in 0.1-5% by weight, preferably 0.1-2% by weight and more preferably 0.1- 1 % by weight, based on the total weight of the ink.
5. An inkjet ink as claimed in any one of claims 1 to 4, wherein the polyoxyalkylene alkyl/alkenyl ether surfactant is a polyoxyethylene alkyl/alkenyl ether surfactant.
6. An inkjet ink as claimed in any preceding claim, wherein the polyurethane (meth)acrylate dispersion is present in 30-95% by weight, based on the total weight of the ink.
7. An inkjet ink as claimed in any preceding claim, wherein the polyurethane (meth)acrylate dispersion has a number average molecular weight of over 500 Daltons to 20,000 Daltons.
8. An inkjet ink as claimed in any preceding claim, wherein the ink further comprises a humectant.
9. An inkjet ink as claimed in any preceding claim, wherein the ink further comprises a synthetic thickener.
10. An inkjet ink as claimed in any preceding claim, wherein the ink further comprises a colouring agent.
11. An inkjet ink as claimed in claim 10, wherein the colouring agent is a dispersible pigment.
12. An inkjet ink as claimed in any preceding claim, wherein the ink comprises 40-95% by weight of water, based on the total weight of the ink.
13. A cartridge containing the inkjet ink as claimed in any preceding claim.
14. A printed substrate having the ink as claimed in any of claims 1 to 12 printed thereon.
15. A method of inkjet printing comprising inkjet printing the inkjet ink as claimed in any of claims 1 to 12 onto a substrate, drying and curing the ink.
