The present invention provides a method for applying multiple ink and/or coating layers on a substrate. At least one of the ink and/or coating layers contains one or more photoinitiators, and at least one of the ink and/or coating layers does not contain any photoinitiators. In certain embodiments, all of the ink and/or coating layers are wet trapped and the entire print construct is cured by exposure to UV radiation after all of the ink and/or coating layers have been applied. In certain embodiments, the wet trapping method of the present invention can be used to prepare laminates.

In a resin for an active-energy-ray-curable ink containing a rosin-modified polyester resin, the rosin-modified polyester resin includes a reaction product of a material component containing rosins, a dibasic acid, and a polyol. The rosin-modified polyester resin has an ester bond in an amount of 5.20 mol/kg or more and 7.20 mol/kg or less. The rosin-modified polyester resin has an acid value of 1 mgKOH/g or more and 30 mgKOH/g or less. The rosin-modified polyester resin has a hydroxyl value of 1 mgKOH/g or more and 40 mgKOH/g or less.

A radiation curable liquid includes at least one free radical polymerizable monomer or oligomer, at least one diffusion hindered acetalyzation catalyst, and at least one diffusion hindered hydroxyl containing compound. The radiation curable liquid applied to a substrate prevents migration of very low viscous monomers, such as vinyl ether acrylate monomers, into the substrate.
