In general, blue light refers to a blue light having a wavelength of 380 nm to 500 nm in visible light, and has a short wavelength and a high energy.
Such a blue light is emitted through a liquid crystal screen of an electronic device such as a smart phone, a tablet or a computer monitor, which has been spreading rapidly in recent years, and is also emitted through a lighting device such as a led lighting lamp.
Because blue light is stronger than other light, it shrinks the eyes, increases the fatigue of the eye by overtaxing the eye muscles, which causes tension and clumps the shoulders and neck. It can also reach the inside of the eye with strong wavelengths and energies, which can have a negative effect and can directly affect the retina and cause damage.
These blue lights also affect sleep health, which tells us the time to sleep by separating day and night through the amount of light reaching the retina. However, due to the effects of various digital devices and LED lighting, the exposure to blue light continues to reduce the secretion of hormones (melatonin) that induce sleep, thereby lowering the quality of sleep.
Accordingly, a protective film or the like capable of blocking blue light has recently been developed.

Experimental Example 1. Adhesion by composition weight and Blue Light Blocking rate
Based on the weight of the composition contained in the blue light-shielding film, the adhesive strength and the blue light blocking rate were tested on the basis of Example 1 and Comparative Examples 1 and 2.
Evaluation results are expressed using percentages, and the closer the percentage is to 100, the better the effect.
(1) Comparative Example 1
Comparative Example 1 was prepared in the same manner as in Example 1 except that 1 to 10 parts by weight of lauryl acrylate and 1 to 5 parts by weight of tetrahydrofurfuryl acrylate (THFA), based on 100 parts by weight of bifunctional urethane acrylate oligomer The

(3) Experimental results
As a result of the test, it was found that the adhesive composition and the blue light-shielding composition of Comparative Example 1, which contained less adhesive agent and blue light-shielding composition than Example 1, contained a relatively small amount of adhesive composition and blue light-shielding composition.
In addition, it can be predicted that the composition is less contained and the film formation rate is low, so that the film can be broken well.
Comparative Example 2 shows that the adhesive composition and the blue light blocking composition are more abundant than those of Example 1, and that the adhesive composition, lauryl acrylate and defoamer, and the blue light blocking composition, benzene, methyl isobutyl ketone and ethylene dysteine, Less.
Here, the lauryl acrylate functions to increase the adhesive strength, and the defoaming agent is a composition used to remove harmful bubbles.
Accordingly, the adhesive composition containing relatively less lauryl acrylate and antifoaming agent may deteriorate the adhesive strength, and the bubble removal rate may be low, so that the composition may not be dissolved well.
In addition, the blue light-shielding composition containing benzene, which determines the degree of film formation as a fine particle, and methyl isobutyl ketone and ethylene dicisteine, which determine the solubility and coatability of the resin in the composition, And the degree of formation of the film may be weak.
According to the experimental results, in Comparative Example 2, the blue light blocking rate is high at an adhesive force of 75%, a blue light blocking rate of 94%, and a film forming rate of 40%, but it is difficult to apply to the present invention because adhesive strength and film formation rate are remarkably low.
