Abstract
A process for laser reflecting flip-flop printing on transfer papers for screen printing is disclosed. A substrate consisting of a base paper, a glue, a transparent tape, a transparent resin, a hydrophilic paint and a metal layer is manufactured by a vapor deposition method. A flip-flop ink having a predetermined pattern as printed on the substrate. The metal layer which is not covered by the ink is etched by an alkaline solution.
The alkaline solution is neutralized by an acid solution. The substrate is washed and then dried so that the transfer printing papers having a flip-flop effect are obtained.
The alkaline solution is neutralized by an acid solution. The substrate is washed and then dried so that the transfer printing papers having a flip-flop effect are obtained.
Description
BACKGROUND OF THE INVENTION
The present invention relates to a process for transfer printing papers. More particularly, the present invention relates to laser reflecting flip-flop printing on transfer paper for screen printing.
Conventional process for transfer printing papers involves printing ink having a determined shape on a metal layer which is provided on substrate, resulting in an aesthetic effect due to the combination of the ink and reflecting effect of the metal layer.
However, the conventional transfer printing papers still need to be modified due to the following reasons:
1. Most of the conventional transfer printing papers are monochromatic.
Multichromatic effect can be achieved by printing a plurality of colors, however the printing process will be uneconomic and time-consuming.
The present invention relates to a process for transfer printing papers. More particularly, the present invention relates to laser reflecting flip-flop printing on transfer paper for screen printing.
Conventional process for transfer printing papers involves printing ink having a determined shape on a metal layer which is provided on substrate, resulting in an aesthetic effect due to the combination of the ink and reflecting effect of the metal layer.
However, the conventional transfer printing papers still need to be modified due to the following reasons:
1. Most of the conventional transfer printing papers are monochromatic.
Multichromatic effect can be achieved by printing a plurality of colors, however the printing process will be uneconomic and time-consuming.
2. Color migration might occur during the colors printing, thus reducing the yield of process for transfer printing papers.
3. The aesthetic effects might be diminished since the colors will be blurred due to overlapping.
In view of the drawbacks occurring in the prior art methods, the present invention solves the problems heretofore commonly in. existence.
It is the purpose of this present invention; therefore; to mitigate and/or obviate the above-mentioned drawback in the manner set forth in the detailed description of the preferred embodiment.
It is an object of this invention to provide a process for transfer printing papers having a flip-flop effect in an economic and time saving manner.
Further objects and advantages of the present invention will become apparent as the following description proceeds, and the features of novelty which characterize the invention will be pointed out with particularity in the claims annexed to and forming a part of this application.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIME
The process for laser reflecting flip-flop printing on transfer paper for screen printing is performed at 22°C to 25°C a humidity of 75% to 85%.
The first step is the manufacture of a substrate consisting of a base paper, a glue, a transparent tape; and transparent resin, a hydrophilic paint and a metal layer is sequence by a vapor deposition method.
The second step is to print a flip-flop ink of determined patterns on the substrate by means of a screen printing. The flip-flop ink is prepared from applying a metal powder such as A1 and Ni to a solvent,,mixing the solution by a mixer at 1000 to 1500 rpm for 5 to 10 minutes, adding a defoaming agent and a leveling agent and further mixing 2 to 3 minutes, adding acrylic resin and butylated melamine resin, and then adding calcium carbonate and an anti-settling agent. The surface of the flip-flop ink which is illuminated by a light source, may, depending on the visual angle, have different colors.
The flip-flop effect is achieved by using only one ink, i.e., it is not necessary to perform a plurality of printing steps for obtaining the flop-flop effect as used in prior art methods.
The third step is to dry the substrate thus obtained in the previous step and then immerse the substrate into a weak alkaline solution, for example, a sodium carbonate solution having a ratio of sodium carbonate to water of 1:5 and a temperature of 30°C to 35°C., for 10 to 15 seconds so that the metal layer which is not covered by the ink and the corresponding portions of the hydrophilic paint and the transparent resin are etched simultaneously.
The fourth step is to immerse the substrate thus obtained in the previous step into a weak acid solution, for example a glacial aectic acid solution having a ration of glacial aceteic acid : water of 1:5 and a temperature of 30°C to 40°C., for about 5 seconds to neutralize the alkaline solution remaining on the substrate.
The fifth step is to wash the substrate thus obtained so as to completely remove the remaining acid solution, alkaline solution, powders of metal layer, hydrophilic paint, and transparent resin.
The sixth step is to air dry the substrate thus obtained in the previous step or perform the drying at 30°C to 40°C.
After the dried substrate is effected a surface finishing treatment, a transfer printing paper having a combination of the flip-flop effect of ink and the reflecting effect of the metal layer is obtained.
After the transfer printing paper is subjected to a static treatment, the ink is directly applied to an object and then the base paper and glue axe removed, so that the combination of the flip-flop effect of ink and the reflecting effect of the metal layer imparts the object with a multichromatic effect when visual angles vary. Thus, the third party will find it difficult to imitate and copy the special effects of the present invention.
Accordingly, the present invention provides a process for transfer printing papers having a flip-flop effect, in which the substrate having a metal layer thereon is formed with a flip-flop ink and the metal Iayer is etched by an alkaline solution, resulting in the transfer printing paper having a flip-flop effect. The transfer printing paper of the present invention overcome the shortcomings of the conventional transfer printing paper and also can be produced in an economic and ime-saving manner.
In view of the drawbacks occurring in the prior art methods, the present invention solves the problems heretofore commonly in. existence.
