Title: PRINTING METHOD AND INK
Abstract:
The present invention provides a method of inkjet printing comprising the steps of: (i) providing an inkjet ink comprising: more than 5% by weight of an N-vinyl amidemonomer,an N-acryloyl amine monomerand/or an N-vinyl carbamate monomer, based on the total weight of the ink; 20 to 55% by weight of isobornyl acrylate, based on the total weight of the ink; a difunctional (meth)acrylate monomer selected from 1,4-butanediol diacrylate, 3-methyl-1,5-pentanediol diacrylate, 1,6- hexanediol diacrylate, 1,8-octanediol dimethacrylate, 1,9-nonanediol diacrylate, 1,10-decanediol diacrylate, 1,11-undecanediol dimethacrylate, 1,12-dodecanediol dimethacrylate, tricyclodecane dimethanol diacrylate, tripropylene glycol diacrylate, dipropylene glycol diacrylate and tetraethylene glycol diacrylate; a radical photoinitiator; optionally a colorant; and optionallya passive resin; (ii) inkjet printing the inkjet ink onto a polypropylene substrate; and (iii) curing the inkjet ink. The present invention also provides an inkjet ink comprising: more than 5% by weight of an N-vinyl amidemonomer,an N-acryloyl amine monomerand/or an N-vinyl carbamate monomer, based on the total weight of the ink; more than 35% by weight of isobornyl acrylate, based on the total weight of the ink; a difunctional (meth)acrylate monomer selected from 1,4- butanediol diacrylate, 3-methyl-1,5-pentanediol diacrylate, 1,6-hexanediol diacrylate, 1,8- octanediol dimethacrylate, 1,9-nonanediol diacrylate, 1,10-decanediol diacrylate, 1,11- undecanediol dimethacrylate, 1,12-dodecanediol dimethacrylate, tricyclodecane dimethanol diacrylate, tripropylene glycol diacrylate, dipropylene glycol diacrylate and tetraethylene glycol diacrylate; a radical photoinitiator; optionally a colorant; and optionally a passive resin.
