Abstract
A method of water transfer printing is provided. The method including the following operations. A water transfer printing film is received. An information body is transferred to a printing substrate without use of an organic solvent-containing activator prior to transferring the information body. The water transfer printing film includes a superabsorbent film, a water-based resin layer on the superabsorbent film, the water-based resin layer, and the information body on the water-based resin layer. The information body includes a water-based colorant and a water-based resin.

A method of water transfer printing, the method comprising:
- receiving a water transfer printing film, the water transfer printing film comprises:
- a superabsorbent film;
- a water-based resin layer 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 %, a polyethylene glycol of 1 wt % to 2 wt %, a calcium carbonate of 5 wt % to 10 wt %, and a water of 18 wt % to 40 wt % followed by drying;
- and
- an information body on the water-based resin layer, wherein the information body comprises a water-based colorant and a water-based resin;
- and
- transferring the information body to a printing substrate without use of an organic solvent-containing activator prior to transferring the information body.
A method of water-based transfer printing, the method comprising:
- providing a water transfer printing film having a superabsorbent film, a water-based resin layer positioned on the superabsorbent film, and a water-based information layer on the water-based resin layer;
- placing the water transfer printing film on a water surface such that the superabsorbent film absorbs water to become softened, the water permeates through the superabsorbent film, the water-based resin layer, and reaches the water-based information layer to produce adhesiveness in the water-based information layer;
- and
- transferring the water-based information layer onto an object without the use of an organic-solvent based activator prior to the transferring.
