Description

White pigment foil
Technical Field
The invention relates to the field of pigment foils, in particular to a white pigment foil.
Background
Transfer printing is a special printing technology, and is generally a process of transferring a color pattern onto the surface of other materials by using an adhesive through hot pressing, so as to complete the transfer printing from a colored coating or color pattern on a transfer printing film onto the surface of other materials.
Transfer films of this type are generally: 1. heat transfer film (alumite, bronzing film): can be subdivided into an alumite hot stamping foil with an aluminum coating and a pigment foil without the aluminum coating; 2. transferring a printing film: printing and coating a color pattern on a film or paper substrate, and transferring the color pattern to the surface of other materials by an adhesive; 3. thermal transfer ribbon (digital printing film): and thermally printing the color layer on the film to the surface of other base materials by a thermal transfer printer to form character patterns.
The currently commonly used thermal transfer film has the following structure:
the first layer is a base film layer. The base film is generally a polyester film with a thickness of 12 to 16 μm. Mainly plays a role of supporting the coating. The packaging form is a reel type, and is convenient for continuous processing, storage and transportation.
The second layer is a release layer. The paint of the release layer is organic silicon resin or wax liquid, and the function of the paint is to enable the color adhesive layer to be quickly separated from the base film and adhered to an object to be hot stamped during hot stamping. The release layer has good release effect, otherwise the quality problems of hot stamping color, floating, non-uniform and the like can be caused.
The third layer is a color adhesive layer. The color adhesive layer is prepared by using pigment as main body and adding adhesive, alcohol solvent, other stuffing, etc. in certain proportion. The various colours of the coloured foil depend mainly on the application and formulation of this layer.
For white pigment foil, white titanium dioxide is more commonly used, but when the addition amount of titanium dioxide is larger, the coloring layer obtained by the formula and the preparation process in the prior art often has the phenomenon of powder falling, and great inconvenience is brought to production and use.

Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.

Evaluation of Performance
The test method is as follows:
1. respectively sticking the adhesive tapes on the coloring layers of the products of the examples 1-6 and the comparative examples 1-6, fully pressing to ensure that the adhesive tapes completely cover the coloring layers, tearing off the adhesive tapes, and observing that no titanium dioxide remains on the adhesive tapes and no residual titanium dioxide remains, wherein the adhesive tapes are marked as 0 level; a small amount of residual titanium dioxide is marked as grade 1; a large amount of titanium dioxide remained, as grade 2.
2. Repeatedly poking the products of examples 1-6 and comparative examples 1-6, repeating the above operation again, observing whether the titanium dioxide is wiped off or not, and marking as 0 grade without any titanium dioxide; wiping off a small amount of titanium dioxide, and marking as grade 1; a large amount of titanium dioxide was wiped off and scored as grade 2.
3. Immersing the products of examples 1-6 and comparative examples 1-6 in water at 100 ℃ for 5h, drying, repeating the operation again, observing whether the titanium dioxide is wiped off or not, and marking as 0 grade if no titanium dioxide is wiped off; wiping off a small amount of titanium dioxide, and marking as grade 1; a large amount of titanium dioxide was wiped off and scored as grade 2.
