Abstract
The present invention relates to an ultraviolet curable high refractive liquid adhesive composition, and more particularly, to an adhesive composition used for bonding a cover glass and a plastic, and more particularly, to an adhesive composition used for bonding a cover glass and a plastic, The present invention relates to an ultraviolet curable high refractive index liquid adhesive composition capable of obtaining an adhesive having a high refractive index by using a polymer to improve low refractive index problems of existing resins.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultraviolet curable high refractive liquid adhesive composition, and more particularly, to an ultraviolet curable high refractive liquid adhesive composition used in a liquid type transparent adhesive used for bonding a touch panel to a glass and a plastic film.
In general, demand for touch panels is rapidly increasing as smartphones and tablet PCs are growing. It is expected that demand will explode with the growth of the mobile device market in the future. In particular, touch panels are being applied to more than 90% of smart phones due to popularization of smart phones.
There are a few requirements for adhesives used in such touch panels, one of which is that they should not impair visibility in relation to optical properties. This decrease in visibility is mainly caused by reflection and refraction of light. In addition, optical properties such as optical uniformity and transparency are required for the adhesive in order to improve the visibility. It is required to be optically uniform throughout the display on the front side to maintain the image quality of the display and also to have a high transmittance so as not to reduce the brightness characteristic of the display.
On the other hand, in terms of mechanical properties, the adhesive should be able to improve the stability of the device by bonding the touch panel and the LCD. If there is a defect in the adhesive layer when bonding with an adhesive, the film is peeled off and causes defects on the screen. Further, it is difficult to change the size of the adhesive in the driving environment, so that shrinkage and deformation of the adhesive film should not occur.
In the past, optically clear adhesive tapes and optically clear liquid adhesives have been developed as a method for satisfying the above-mentioned demanded properties of the adhesive.
Of these, optically transparent adhesive tapes have been widely used as adhesives for touch panels, and generally have a merit that they can be made very thin because they act as adhesives as their own materials without a base film or the like. Acrylic materials have been used for these materials, which have a high transmittance. The advantage of transparent adhesive tape is that it is excellent in adhesiveness to glass, metal, and plastic, so that it can be applied to various materials and is excellent in resistance to moisture and heat. In addition, it has characteristics that it can be easily handled in the process because it has the shape of tape and does not require curing process to induce additional curing reaction. In addition, since it is an adhesive itself, it has a feature that it does not flow out from the adhesive portion, and since it does not need a curing process, it has an advantage that it can be bonded regardless of the presence of opaque patterns.
Generally, the transparent adhesive tape is cut and supplied to a portion to be bonded at an appropriate size, rather than being formed in a sheet form, so that the problem of flow before curing of the adhesive generated in the liquid resin type adhesive does not occur.
However, since the transparent adhesive tape has the above-mentioned advantages, it is made of a tape, so that there is a problem that if there is a surface uneven structure, a defect occurs. In the case of a glass substrate, there is no problem because it is flat. However, since layers having different thicknesses are printed on the edge of a mobile device or the like, surface irregularities exist, and a transparent adhesive tape as a gel adhesive does not completely fill these irregularities A defect is generated. Another problem with transparent adhesive tapes is that they are expensive. It has a problem that it is applied in different form to each product because it is cut and used suitably for each product, and accordingly, the unit price is increased.
The transparent adhesive tape is generally applied to a cover glass using a lamination process, and the tape is applied using a drum. The tape is fixed on the drum, the protective film is removed from the tape, and a pressure is sequentially applied from one end of the tape so as to uniformly compress the tape without causing defects.
On the other hand, the ultraviolet ray curable liquid transparent adhesive has excellent characteristics of adhesion to glass, metal and plastic, and is excellent in resistance to moisture and excellent in thermal stability. In particular, since the adhesives can be suppressed due to the occurrence of defects at uneven portions, which is the biggest disadvantage occurring when using a transparent adhesive tape, it is inevitable to develop a liquid transparent adhesive that has better performance than the present.
