US 12,097,724 B2 · Eco-friendly activator-free water transfer printing film and method of printing the same

Abstract

An eco-friendly activator-free water transfer printing film includes a water-based modified acrylic copolymer resin layer set on a superabsorbent film and made of a water-based modified acrylic copolymer resin which is formed by acrylic copolymer emulsion, polyvinyl alcohol (PVA) resin and polyvinylpyrrolidone (PVP) resin and provided crosslinking an end surface with the water-based modified acrylic copolymer resin layer after another end surface of the superabsorbent film absorbs water and becomes softened; and an information body set on the water-based modified acrylic copolymer resin layer; so that the present invention is simply set on a water surface to crosslink the superabsorbent film with the water-based modified acrylic copolymer resin layer to produce the adhesiveness of the water-based modified acrylic copolymer resin layer without using any activator.

Dependent claims

A water transfer printing film, comprising:

a superabsorbent film;
a water-based resin layer set on the superabsorbent film,
the water-based resin layer is formed from a composition comprising an acrylic copolymer emulsion of 23 wt % to 45 wt %, a polyvinyl alcohol (PVA) resin of 15 wt % to 20 wt %, a polyvinylpyrrolidone (PVP) resin of 15 wt % to 20 wt %, polyethylene glycol of 1 wt % to 2 wt %, calcium carbonate of 5 wt % to 10 wt %, and water of 18 wt % to 40 wt % followed by drying;
and
an information body set on the water-based resin layer, wherein the information body comprises a water-based colorant and a water-based resin;
wherein the information body transferable to a printing substrate without use of an organic solvent-containing activator prior to transfer.
