Description

METHOD FOR PRODUCING OPTICAL COMPONENT, ADHESIVE COMPOSITION KIT, AND COATING COMPOSITION}

This invention relates to the manufacturing method of an optical component, the adhesive composition kit used for the manufacturing method of the said optical component, and the coating composition which comprises the said adhesive composition kit.

Since display bodies, such as a liquid crystal display body used for an optical display apparatus, use a thin glass substrate, the protection panel is provided through the air layer for the purpose of protection of a glass substrate. In addition, as the application expands, not only a protective panel but also a touch panel is often provided on the front of the display panel.

In recent years, bonding a protective panel or a touch panel directly to a display body is performed as a method of satisfying simultaneously the fall of visibility caused by an air layer and reinforcement of a display body.

A sheet-form double-sided adhesive sheet (patent document 1) and liquid resin are used for bonding. Moreover, bonding of a touch panel and a protection panel is also performed by the same method.

In addition, with the diversification of imaging technology, optical display devices (hereinafter referred to as 3D display devices) for displaying three-dimensional images (so-called 3D images) or three-dimensional images (so-called 3D images) are increasing, but the manufacture of these optical display devices is increasing. WHEREIN: A double-sided adhesive sheet and liquid resin are used for bonding of optical component structural members, such as a display body, a protective panel, and a touch panel.

For example, when an energy ray-curable liquid resin is used for bonding a protective panel and a touch panel or a display body, the light shielding printing of a protective panel, the flexibility or wiring of a touch panel, the wiring of a display panel, the black matrix, or an optical film Since energy ray is shielded by this, the hardening of liquid resin is a problem.

Reaction curable resin composition of the thermosetting combined use type is proposed about the hardening defect of such a light shielding part (patent document 2).

In addition, in the manufacture of 3D display devices which are rapidly expanding in recent years, when an energy ray-curable liquid resin is used, an energy ray is more than a conventional optical component by a parallax barrier, a polarizing film, an optical film of a lens unit or a display body. Since shielding or attenuation is a problem, the problem that hardening defects and hardening energy become large becomes more important.

That is, when the liquid crystal display body is used for a 3D display apparatus, since the recent liquid crystal display body is manufactured by the photo-alignment technique, the problem that excessive irradiation of the energy beam also largely hinders the display characteristic of a liquid crystal display also arises.

On the other hand, the size of the display unit bonded with the energy ray-curable liquid resin is increasing year by year from the mobile size to the monitor or TV size, and in the manufacture of the monitor or TV size, a huge UV device (for example, a metal halide light source or LED) Since a conveyor or batch type ultraviolet irradiation device for illuminating the light source employing a light source) is required, an increase in production equipment cost, an increase in line area, and an increase in UV process time are also problems.

An object to be solved by the present invention is an optical component capable of sufficiently curing the reactive curable resin composition even at a point where light does not reach when the optical component constituting member is bonded through the reactive curable resin composition to produce an optical component.

According to the production method of the present invention, after the reaction curable resin composition in the step (3) and the coating composition are in contact with each other, the reaction initiator is diffused into the reaction curable resin composition layer and near the room temperature described in the step (4). It is thought that the polymerization reaction proceeds at the temperature of.

According to the manufacturing method of this invention, in the process (4), by taking the hardening aspect which hardening reaction of a reaction hardening type resin composition starts with a reaction initiator, even if the light does not reach, hardening reaction hardening type resin composition is sufficient. Can be. Moreover, the damage to display bodies, such as a liquid crystal display body, can be greatly reduced compared with the conventional hardening method of the reaction hardening type resin composition only by energy-beam irradiation.

The process (1)-(4) of this invention is demonstrated.

(1) It is a process of arrange | positioning the coating composition containing a reaction initiator on the one or both surfaces of the opposing surface of optical component structural members A and B. By the step (1), a display structural member having a coating containing a reaction initiator is obtained.

It is not specifically limited if it is a member which comprises an optical component as optical component structural members A and B, A protection panel, a touch sensor panel, a display body, a 3D system (differential barrier glass, parallax barrier film, parallax barrier LCD, lens unit) Etc. can be mentioned. These optical component constituent members A and B may be transparent plates, and may have a light shielding portion formed by light shielding ink. The light shielding ink may be a known light shielding ink, and examples thereof include aqueous ink, solvent ink, thermosetting ink, and energy ray curable ink. Here, a light shielding part means the point which the light formed by the light shielding ink of a protection panel and a display body or a touch sensor panel, or the light shielding ink of a touch sensor panel and a display body does not touch, for example.

In the present invention, the coating composition may be disposed on the light shielding portion. In the present invention, "the coating composition is arranged in the light shielding portion" means that the coating composition is disposed only on the surface of the light shielding ink layer (for example, FIG. 4 (1)), or the light shielding ink layer is not disposed. As the surface of the optical component constituent member, the coating composition is disposed only on the surface on which the light shielding portion is formed by the light shielding ink layer disposed on the other optical component constituent member (for example, FIGS. 4 (2) and (3)). Say that. In the present invention, the coating composition may be disposed only on the surface where no light shielding ink layer is disposed, only on the light shielding portion, and on the surface where the light shielding portion and the light shielding ink layer are not disposed.

As a reaction initiator, the reaction initiator according to the reaction aspect of the reaction hardening type resin composition used by the process (2) mentioned later is mentioned. Specifically, the reaction initiator mentioned later is mentioned.

In the step (1), the coating composition is disposed on one or both surfaces of the opposing surfaces of the optical component constituent members A and B. In view of the curability of the reaction curable resin composition, the coating composition is preferably disposed on both surfaces of opposing surfaces of the optical component constituent members A and B.

Process (1) may be performed in-line with respect to the manufacturing line of an optical component, and may be performed off-line.

In the step (1), as a method of disposing a coating composition, there are a spray method and a coater method, and the amount of the coating composition is preferably 0.001 to 100 g / m 2, more preferably 0.005 to 10 g / m 2. More preferably, they are 0.01-1.00 g / m <2>.

In process (1), a coating composition may arrange | position a liquid coating composition by application | coating. In this case, the coating composition may be dried to cure the solvent contained in the coating composition by drying. In such a case, it is preferable to apply heat at a temperature of preferably 40 to 200 ° C for 10 seconds to 2 hours.

In the step (1), the liquid coating composition further contains a resin curing agent selected from the group consisting of a thermosetting agent and / or an energy ray initiator, and after the coating composition is disposed by application, heat and / or energy You may harden a coating composition with a wire. That is, step (1) is step (1A) and step (1B):

(1A) A coating composition containing a reaction initiator on one or both surfaces of opposing surfaces of optical component constituent members A and B, the coating composition further comprising a resin curing agent selected from the group consisting of a thermosetting agent and a photoinitiator. Placing process, and

(1B) The process of hardening a coating composition by applying heat and / or irradiating an energy ray may be sufficient. The compound mentioned later can mention the thermosetting agent and an energy-beam initiator in a process (1A). Here, the resin curing agent used in the step (1A) may be used to cure the coating composition, or may be used to cure both the coating composition and the reaction curable resin.

In the step (1B), the conditions for applying heat to cure the coating composition are not particularly limited as long as the polymerization reaction of the reactive curable resin contained in the coating composition proceeds. Preferably at 60-200 degreeC, More preferably, the temperature of 80-160 degreeC is preferably 10 seconds-24 hours, More preferably, the thing which adds heat for 0.1 to 12 hours is mentioned.

In the step (1B), the conditions for curing the coating composition by irradiation with energy rays are not particularly limited. For example, the amount of accumulated light is preferably 50 to 3,000 mJ / cm 2, and more preferably 50 to 2,000 mJ. / Cm <2>, More preferably, it is 50-1,000 mJ / cm <2>. Examples of the energy rays include electron beams, X rays, ultraviolet rays, and high energy electron beams or electromagnetic waves such as visible light in a low wavelength region.

Process (2) is a process of arrange | positioning a reactive resin composition to the surface of the said coating composition arrange | positioned at the said surface, and at least 1 surface of the said surface in which the said coating composition is not arrange | positioned. In the step (2), as a method of disposing the reaction curable resin composition, there are a dispensing method, a coater method, and the like, and the batch amount of the reaction curable resin composition is preferably 10 to 100 µm, more preferably 25 to 500 µm. More preferably, it is 50-300 micrometers.

An energy cleavage initiator is contained in the reaction curable resin composition used in the step (2), and before the step (4), an energy ray is irradiated to the reaction curable resin composition, so that a range of light reaches the energy cleavage initiator. When it is made to polymerize and harden | cure, it is preferable because the bonded optical component system is physically stabilized and the polymerization reaction by the reaction initiator in the coating composition in a process (4) is performed in a stable environment. In particular, in the step (1), when the coating composition is disposed only in the light shielding portion, the reaction curable resin composition contains an energy cleavage initiator. Thereby, in a light shielding part, hardening reaction advances by the contact of the reaction initiator and reaction-curable resin composition contained in a coating composition, and the part to which light is irradiated reacts curable resin by the energy cleavage initiator contained in reaction-curable resin composition. Curing reaction proceeds. Moreover, it is more preferable that the reaction initiator contained in the coating composition used in process (1) is not an energy cleavage type initiator.

As conditions for irradiation of an energy ray, what was illustrated by process (1B) including a preferable thing is mentioned.

The step (3) is a step of bonding the optical part structural members A and B so that the coating composition and the reaction curable resin composition come into contact with each other through the reactive resin composition between the optical component structural members A and B. Thereby, the bonded body of optical component structural members A and B is obtained. The coating composition and the reaction curable resin composition are brought into contact with each other by the step (3). In the step (3), when the optical component constituent members A and B are bonded together, a means such as compression may be used to promote contact between the reaction curable resin composition and the coating composition.

Step (4) is a step of starting the polymerization reaction with the reaction curable resin composition with a reaction initiator to cure the reaction curable resin composition. In the step (4), the reaction initiator is diffused in the reaction curable resin composition layer to advance the polymerization reaction by leaving the assembly of the optical component constituent members A and B obtained in the step (3). Such conditions are not particularly limited as long as the temperature and time at which the polymerization reaction of the reaction curable resin composition proceeds. Preferably it is 10-60 degreeC, More preferably, it is 15-40 degreeC, More preferably, it is the environment of 20-30 degreeC, Preferably it is 0.1 to 24 hours, More preferably, it is 0.5 to 12 hours, More preferably Under the conditions of 1 to 6 hours, the reaction curable resin composition may be initiated and cured by the reaction initiator in the coating composition.

In addition, in a process (1), when a coating composition is arrange | positioned only in a light shielding part, in a process (4), parts other than a light shielding part irradiate an energy ray, and are an energy cleavage type contained in reaction hardening type resin composition The curing reaction of the reaction curable resin proceeds with the initiator. Here, the conditions of irradiation of an energy ray can mention what was illustrated at the said process (1B).

Thereby, the optical component obtained by the manufacturing method of this invention is obtained.

According to the production method of the present invention, since the resin composition was applied directly to the point where the step occurs, the thickness variation of the resin composition occurred. However, since the printing step and the polarizing plate step can be filled with the coating composition, there is a difference in the bonding thickness. The display nonuniformity generated by can be solved. Moreover, the chemical crack which was easy to generate | occur | produce with thickness variation of a resin composition can be suppressed by coating the edge part of a polarizing plate.

[Coating Composition]

The coating composition of this invention is demonstrated. The coating composition contains a reaction initiator capable of initiating the polymerization reaction of the reaction curable resin composition.

[Reaction Initiator]

The reaction initiator contained in the coating composition includes a radical generator, a cation generator, an anion generator, and a polycondensation / polyaddition reaction initiator. A reaction initiator can be used according to the polymerization reaction aspect of reaction hardening type resin composition.
