TABLE 1 selection of the weight parts of the raw material components
TABLE 2 selection of Components in specific examples 1-3 and comparative examples 1-4
Product effect test
The paper-based pyrography transfer materials prepared in examples 1-3 and comparative examples 1-4 were tested for test items including pattern peeling, transfer effect, print fixing, color density. The specific test method is as follows:
(1) Pattern peeling condition: a standard CMYK image is sprayed on a paper-based hot stamping transfer material of 0.125m2, powder is sprayed on the surface of the transfer material, powder shaking and hot stamping are carried out, stripping is carried out, stripping force is measured, and the stripping force is expressed by light weight, medium weight and heavy weight, wherein 10-50g is light weight, 50-100g is medium weight and 100+g is heavy weight, the smaller stripping force indicates easier stripping, and the light stripping force indicates easier stripping.
(2) Transfer rate: transfer papers of the above examples and comparative examples were taken to observe the residual condition of ink on the transfer papers, and the weight ratio of the residual images after quantitative transfer was measured. If the residual image on the transfer paper has fewer marks, the transfer effect is good, and if the residual image on the transfer paper has more marks, the transfer effect is poor.
(3) Printing ink fixing conditions: the highest amount of white ink that can be printed without running ink.
(4) Color density: and taking the printed fabrics of which the transfer printing is finished in the above examples and comparative examples, and detecting the color density value of the color block by using an alix-RITE EXACT spectrodensimeter, wherein the larger the color density value is, the darker the color expression depth is, the smaller the color density value is, and the lighter the color expression depth is. The test results are shown in Table 3.
Table 3 results of performance tests of examples and comparative examples
As can be seen from Table 3, the paper-based pyrograph transfer materials provided in examples 1-3 of the present invention have good transfer effect, no residue, high color fixation, light peeling force, and high pattern color fastness after transfer. In comparative example 1, no water-resistant barrier auxiliary agent is added, the barrier property of the prepared paper-based pyrography transfer printing material bottom coating is poor, and in the transfer printing process, the components of the release layer and the components of the top coating penetrate into the bottom coating to influence the transfer printing stripping force and the image retention, so that the color fixing capability and the pattern color fastness are low.
The inorganic filler used in the primer coating of comparative example 2 is beyond the protection scope of the invention, so that the amount of latex and adhesive in the primer layer is small, the adhesion to paper fibers is weakened, and when the paper is transferred and separated, part of the primer layer remains on the printed pattern, and the high color fastness of the surface of the pattern and the transfer printing effect are affected.
When the dosage of the adhesive of the release coating in the comparative example 3 is less than the protection range of the invention, the release layer has poor water resistance, and the surface coating permeates into the release layer to influence the transfer stripping force and the image residue, so that the color fixing capability and the pattern color fastness are high.
The primer coating of comparative example 4 was not added with an inorganic filler, and the binding force between the primer coating and the release layer was reduced, so that the separation was relatively easy, and when the separated paper was transferred, part of the primer coating remained on the printed pattern, and the surface color fastness of the pattern was high and the transfer effect was affected.
Therefore, the primer layer formed by the specific primer coating and the release layer formed by the specific release coating have barrier property, and the penetration of the release layer and the surface coating to the primer layer is reduced, so that the influence on the transfer printing stripping force is reduced, the image residue is reduced, the transfer rate of the transfer printing film is further improved, and the image resolution is improved
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present invention may be modified or substituted equally without departing from the spirit and scope of the technical solution of the present invention.
