preparation example Construction

[0023] In the specific preparation method of the ultraviolet curable composition of the present invention, the polyurethane acrylic resin, active monomer, photoinitiator and epoxy acrylic resin can be mixed once or step by step. In a preferred situation, first mix the photoinitiator with part of the active monomer to fully dissolve the photoinitiator to obtain a photoinitiator slurry; then mix the polyurethane acrylic resin with another part of the active monomer evenly to obtain a resin component slurry; then Mix the photoinitiator slurry with the resin component slurry evenly. The above mixing is usually carried out at room temperature, and it can also be slightly heated to 30-60°C to speed up the mixing.

[0024] Similarly, in the process of preparing the above-mentioned UV curable composition, a defoamer and a leveling agent may also be added. When the UV-curable composition to be prepared contains a defoamer and a leveling agent, the order of adding the defoamer and the ...

Embodiment 1

[0050] This example is used to illustrate the UV-curable composition disclosed in the present invention and its preparation method.

[0051] With 48g polyurethane acrylic resin (UV-3000B produced by Japan Synthetic Chemical Company, the weight average molecular weight is 18000), 38g dipentaerythritol hexaacrylate (SR399 produced by Sartomer), 2gIrgacure651 (produced by Ciba, Switzerland) and 12 rings An oxyacrylic acid resin (CNUVE151 produced by Sartomer Company) was added into a high-speed mixer, stirred at a speed of 1000 rad / min for 10 min, and filtered to obtain a UV-curable composition S1.

Embodiment 2

[0053] This example is used to illustrate the UV-curable composition disclosed in the present invention and its preparation method.

Abstract

The invention relates to the field of ultraviolet curing composition, and particularly discloses an ultraviolet curing composition and a preparation method thereof and a pattern preparation method. The ultraviolet curing composition comprises polyurethane acrylic resin, active monomer, photo-initiator and epoxy acrylic resin, wherein the weight average molecular weight of the polyurethane acrylicresin is 15,000 to 25,000. The pattern preparation method comprises the following steps of: a, arranging the ultraviolet curing composition between a base material and a die, and making the ultraviolet curing composition contact with the base material and the die, wherein on the die, the part contacted with the ultraviolet curing composition is provided with grains, and the base material and / or the die are transparent; b, performing ultraviolet irradiation in the transparent base material and / or die direction; and c, moving the die, wherein the ultraviolet curing composition is the above the ultraviolet curing composition. When the ultraviolet curing composition disclosed by the invention is used for preparing the patterns, the ultraviolet curing composition does not produce serious shrinkage, can avoid deformation of the base material and improve the product quality.

Description

【Technical field】 [0001] The invention relates to an ultraviolet light curing composition and its preparation method, a pattern preparation method, especially an ultraviolet light curing composition for pattern transfer printing, a preparation method thereof, and a method for preparing pattern by using the composition. 【Background technique】 [0002] At present, more and more decorative films or decorative patterns are applied to the surface of various electronic products, and are favored by consumers because of their good three-dimensional effects and colorful colors; among them, various holographic patterns, especially CD Because of its colorful sparkle effect, CD pattern buttons and screens with sparkle effect have a large market, and major manufacturers have launched similar products. [0003] The main method of producing various holographic patterns on the market is to engrave patterns on metal, quartz or PC sheets coated with silicon dioxide and titanium dioxide altern...
