Combining example 1 and comparative example 1, and combining table 3, it can be seen that the transfer printing paper is coated with the isolation coating to form the isolation layer, the coating is coated with the ink-bearing coating to form the ink-bearing layer, the ink cannot permeate the transfer printing paper, thereby reducing the ink transfer rate of the transfer printing paper, the formation of the isolation layer separates the ink from the transfer printing paper, thereby reducing the probability of the ink entering the transfer printing paper, and meanwhile, the formation of the ink-bearing layer enables the ink to better roll out of the transfer printing paper, thereby improving the ink transfer rate of the transfer printing paper, and improving the ink utilization rate.
In combination with examples 1-3 and Table 3, it can be seen that the transfer rate of the ink on the transfer printing paper can be affected by changing the ratio of the raw materials of the components of the barrier coating and changing the ratio of the raw materials of the components of the ink-bearing coating.
By combining examples 3-7 and table 3, it can be seen that the transfer rate of the ink on the transfer printing paper is changed significantly by further optimizing the ratio of the raw materials of the components of the ink-bearing coating, and meanwhile, the addition of the anti-fouling agent can further reduce the residual amount of the ink on the transfer printing paper, thereby improving the transfer rate of the ink. The antifouling agent is prepared by the synergistic cooperation of three components, so that the antifouling effect of paper is improved, the hardness of the paper is improved, the surface tension of the paper is improved, and the transfer rate of ink is improved.
It can be seen from the combination of examples 7-16 and table 3 that the transfer rate of the ink on the transfer printing paper is greatly affected by the adsorbents with different component ratios, when the three adsorbents are synergistically matched, the transfer rate of the ink is optimal, the transfer rate of the ink on the transfer printing paper is also affected by the expanding agents with different component ratios, and the three expanding agents are synergistically matched and uniformly distributed in the ink bearing layer, so that the transfer rate of the ink is improved.
