Abstract
An eco-friendly activator-free water transfer printing film and its transfer printing method are disclosed. The method includes the steps of: laying a superabsorbent film on a water surface; laying a hydrophilic material on a surface of the superabsorbent film to form a hydrophilic layer, and the hydrophilic material includes an information object, or coated with an information object; absorbing water to soften an end surface of the superabsorbent film contacting with the water surface, and crosslinking the other end surface of the superabsorbent film to the hydrophilic layer; pushing a transfer object towards the hydrophilic layer in water, so that the hydrophilic layer and the superabsorbent film are transferred and printed onto the transfer object. Therefore, the water transfer printing process can be achieved without using any activator to avoid environmental pollutions and prevent jeopardizing human beings or deforming transfer printing patterns.
