Description

Resin composition and film using the same}

The present invention relates to a resin composition and a film using the same, and more particularly, to a resin composition capable of controlling the curl of a film (curl) and a film using the same.

Since glass substrates used in electronic devices and the like have a problem of being easily damaged due to weak impact resistance, transparent films are introduced instead. As transparent films, polycarbonate, polymethyl methacrylate, polyurethane, polystyrene, etc., which exhibit thermosetting or thermoplastic properties, are used. Among them, the transparent plastic mainly used is polycarbonate, which has a light transmittance of about 90%, high impact resistance, and a high refractive index of 1.58, which is high even when compared with the refractive index of glass (1.50 to 1.52). It is widely used as a glass substitute in use.

The thermosetting or thermoplastic polymers are excellent in transparency and impact resistance, but lack scratch resistance and chemical resistance compared to glass materials, and thus use technology to coat them with excellent physical strength and transparent materials to improve them.

As a coating agent, there are a thermosetting or photocuring type, and can be divided into an organic coating agent and an inorganic coating agent. Melamine, acrylic and urethane are used as the organic coating agent. On the other hand, the inorganic coating agent mainly consists of silicone. Organic-inorganic hybrid coatings obtained by reacting an organic silane coupling agent with a silicone-based inorganic material using a sol-gel method are also being studied. When the sol-gel method is used, an organic-inorganic hybrid coating agent having an intermediate property between an inorganic substance and an organic substance can be prepared by reacting an inorganic substance by adding an organic substance.

In the case of thermosetting coatings, silicone-based materials are mainly used, but plastic materials are not suitable because high-temperature treatment is essential. In the case of photocuring, since heat is not directly applied, it is possible to coat a substrate that is difficult to heat-cure at high temperatures such as thermoplastics, wood, and paper. In addition, it is easy to save energy because energy can be input only to the required part.

Commonly used photocurable coating agents include acrylic polymers, urethane polymers, epoxy polymers, and silicon polymers, and are coated by curing them by light irradiation after adding photoinitiators and additives to them. The photocurable coating agent may be divided into a radical polymerization system and a cationic polymerization system.

The coating agent needs to increase the crosslinking density in order to obtain high hardness, and as the crosslinking density increases, the curing shrinkage also increases. Due to the curing shrinkage, a curl phenomenon in which the end of the film is rolled up occurs.

There is a method of using a long molecular weight oligomer or a non-reactive acrylic resin to prevent the curl phenomenon, but this has a problem that the hardness is weakened. To solve this, various organic-inorganic coating liquids containing inorganic colloidal silica particles are used to improve the hardness and abrasion resistance of the coating film, but the solvents that can be used for these organic-inorganic silica particles are water and alcohols. It is limited, and it is difficult to adjust the hardness and low shrinkage balance. In addition, stability problems due to precipitation and gel generation of colloidal silica particles whose silica surface is modified with an organic material or silane may occur, and optical transparency may not be satisfied.

In the conventionally known technique, the photocuring step of the coating is divided into two steps to coat and cure the coating resin composition on the entire surface in the first step, and then apply the hard coating composition to the other side where the hard coating composition is not applied in the second step. Disclosed is a method of canceling the curls generated in the first step by curing in the opposite direction to obtain a flat hard coating film, but there is a problem in that process efficiency is poor because an additional process that requires coating on both sides is required.

Referring to Figure 1, the inward curl means that the film produced by coating the resin composition according to an embodiment of the present invention on the upper substrate and photocuring is dried in the upper direction of the substrate by curing shrinkage, and the outward curl is It means that the film according to an embodiment of the invention is dried in the downward direction of the substrate by curing shrinkage.

For a specific example, the cationic initiator may include one selected from the group consisting of an onium salt system, an organometallic salt system, a diazonium salt system, and combinations thereof. In addition, the cationic initiator may include a non-ionic cationic initiator such as an organic silane-based, latent sulfonic acid-based and other non-ionic compounds.

In this case, the onium salt-based initiator, for example, a diazonium salt (diazonium salt), diaryl iodonium salt (diaryliodonium salt), triarylsulfonium salt (triarylsulfonium salt) or aryldiazonium salt (aryldiazonium salt) It may be one selected from the group consisting of a system and a combination thereof, and the organic metal salt-based initiator may be iron arene.

In order to obtain a high hardness of the film, it is necessary to increase the crosslinking density, thereby increasing the curing shrinkage. Therefore, it is required to control the curl phenomenon in which the end of the film is rolled up due to the curing shrinkage.

Conventionally, in order to prevent the curl (Curl) phenomenon, the inorganic colloidal silica particles are introduced, but there may be a problem that a solvent that can be used is limited and optical transparency is not satisfied.

According to an embodiment of the present invention, a photocurable resin, a first curl-oriented initiator and a second curl-oriented initiator are included, and the first curl-oriented initiator and the second curl-oriented initiator are cured by shrinkage. By providing a resin composition characterized in that the curl orientation of the film is opposite, the curling phenomenon of the film can be controlled by canceling the curl tendency between the first curl-oriented initiator and the second curl-oriented initiator. In addition, unlike the conventional technique of controlling the curling phenomenon by coating twice on both sides, there is no need for an additional process, so the process convenience is high, and due to the ease of the technology capable of controlling the curling phenomenon through simple mixing of the initiator, various photocurable materials It can be applied to curl phenomenon control.
