More specifically, the present invention relates to a liquid photocurable adhesive composition containing 2-hydroxy 3-chloropropyl acrylate (or methacrylate) and a photosensitizer as essential components. In recent years, with the advancement of photosensitive resin technology, photosensitive resins have come to be used for adhesion between two objects, at least one of which is transparent or semitransparent.

The advantage of using a photosensitive resin as an adhesive is that it is a one-component type, so there is no need for mixing work, non-uniformity of the system, defoaming, pot life, etc., as it is a one-component type, and there is no volatilization. Since most of the components can be eliminated, there is no solvent evaporation process, making it possible to bond objects that are impermeable to solvents.The curing time can be extremely shortened.Since it does not cure unless exposed to light, it is suitable for positioning work between objects to be bonded. There are no time restrictions, and the viscosity can be varied over a wide range, so you can freely choose the most suitable viscosity for your work. Because of these numerous advantages, photosensitive adhesives are now commercially available and are beginning to be put into practical use. However, a material with sufficient adhesive strength for glass and plastics such as acrylic resin, which are the most important materials industrially for transparent or translucent objects, has not yet been obtained. As a result of our intensive research, we found that
We have developed a photosensitive adhesive that has excellent adhesion to glass and acrylic resin. That is, the present invention comprises 100 to 5% by weight of 2-hydroxy 3-chloropropyl acrylate (or methacrylate) and 0 to 95% by weight of a polymerizable vinyl monomer and/or a polymerizable prepolymer having a boiling point of 100 qo or higher. The present invention relates to a photosensitive adhesive composition whose main component is a mixture in which 0.1 to 5 parts of a photosensitizer is added to each part.

This monomer A has a high boiling point, no odor, high photopolymerizability, strong polymer, excellent adhesion to glass and acrylic resin, good heat resistance, cold resistance, water resistance, and refractive index. It has become clear that this material has the optimum properties as a raw material for photosensitive adhesives, such as high adhesive properties and good transparency. Monomer A may be used alone, and other polymerizable vinyl monomers, polymerizable premonomers, etc. (hereinafter referred to as "monomer B") may not necessarily be used in combination, but they may be used in combination to impart various performances to the adhesive. It is also possible to do so. For example, monomers can be used to adjust the viscosity of adhesives, to make them water-soluble, to improve the heat resistance of cured films, to prevent them from scattering when objects are damaged, and to reduce the cost of adhesives.
This becomes possible by using B together. Such monomer B has a boiling point of 100 oo or higher, such as monoalkyl esters of (meth)acrylic acid, (
meth)hydroxyalkyl acrylates (excluding monomer A), (meth)acrylic acid, (meth)acrylic acid amides, vinyl esters, styrene and its derivatives,
There are polymerizable vinyl monomers such as allyl alcohol esters. In addition, examples of prepolymers with a boiling point of 10,000 or higher include (meth)acrylic esters of polyester polyols, (meth)acrylic esters of polyether polyols, adducts of polyepoxy compounds and (meth)acrylic acid, and A modified urethane in which hydroxyalkyl (meth)acrylate is bonded via a diisocyanate is used. If the boiling point of the monomer B is less than 100° C., it is not preferable because the evaporation loss is large, causing problems of air pollution and generating bad odors.

If the monomer A content is less than 5% by weight, it is not preferable because the adhesion to glass and acrylic resin and other properties deteriorate.

The photosensitizer used in the present invention may be anything that can initiate the polymerization of the monomers A and B upon irradiation with actinic rays. The active light is preferably a wavelength that is not strongly absorbed by glass or acrylic resin and that effectively excites the photosensitizer, and practically, light in the ultraviolet to visible range is desirable. Examples of photosensitizers that meet these conditions include pendyl, diacetyl, pesosophenone, benzoin, benzoin ether, and anthraquinone.
Preferred light sources for curing the adhesive of the present invention include mercury lamps, ultraviolet crab lamps, metal halide lamps, arc lamps,
There is sunlight, etc. The composition of the present invention may also include a known thermal polymerization inhibitor as an optional component to improve storage stability, a known dye or pigment for coloring, or a non-polymerization inhibitor that is compatible with the composition. The volume and viscosity may be increased using a polymeric filler material. The photosensitive adhesive composition according to the present invention is effective for adhering two light-transmitting objects, at least one of which is transparent or translucent, and has particularly excellent adhesion to glass, acrylic resin, etc.

When the same test was conducted using a composition in which hydroxy 3-chloropropyl methacrylate was removed, the adhesive layer was attacked by moisture and two arcs around the test piece were peeled off. Example 2 A composition consisting of 1 part of 2-hydroxy 3-chloropropyl methacrylate, 5 parts of n-butyl acrylate, 4 parts of polyethylene glycol (molecular weight 200) dimethacrylate, and 2 parts of benzophenone was prepared on a willow glass plate with a thickness of 1 part. A one-sided thick acrylic plate (white) is gradually tilted from one side so that the entire surface is brought into close contact with the glass plate through the composition, and pressure is applied to the entire surface to wash away excess liquid. After the thickness of the liquid was reduced to about 20 peaks, it was irradiated with a 20W ultraviolet honey lamp for 5 minutes from a distance of 5 cm from the glass surface.

The two plates were firmly bonded together, with no bubbles or coloring. Among the above compositions, when a composition using 8-hydroxypropyl methacrylate instead of 2-hydroxy 3-chloropropyl methacrylate was bonded using the same method, the adhesiveness between the glass and the composition was not much different, but it was different from the acrylic board. The adhesion between the compositions was poor and they peeled off at the slightest temperature change or impact. Example 3 2-hydroxy 3-chloropropyl acrylate 6 base parts, pt-butylstyrene 3 sparse parts, polyvinyl petyral resin (degree of petyralization 60 mol%, degree of polymerization 500) 1 base part and penzoin methyl ether 0.1 part of a uniformly dissolved composition was applied to one side of a concave lens with a diameter of 5 mm (f = 1.8).
cc injection, and a convex lens with the same curvature and a diameter of 5 mm was pressed onto the concave surface at once to bring it into close contact.
