2. Description of the Related Art Polymethyl methacrylate (PMMA) and polycarbonate (PC) have been known as resins used for optical materials. However, although PMMA is excellent in transparency, it has problems in heat resistance and moisture resistance, and PC has better heat resistance and moisture resistance than PMMA, but has problems such as large birefringence. A thermoplastic saturated norbornene-based resin, which has excellent transparency, heat resistance, moisture resistance, and low birefringence, has attracted attention as an optical material.

However, thermoplastic saturated norbornene resins have low adhesiveness to adhesives, paints for coloring, UV curable paints for protective coating or fine structure formation, various inorganic films and organic films. There was a problem. As a method of improving the adhesiveness, various types of primer treatment, chemicals, and active energy ray treatment are being studied for the purpose of improving the adhesiveness. This is not preferable in terms of production efficiency.

Therefore, it has been studied to modify the thermoplastic saturated norbornene resin or to add a compounding agent to improve the adhesiveness.

For example, it has been known that 1 to 40% by weight of a rubbery polymer is graft-polymerized on a thermoplastic saturated norbornene resin (Japanese Patent Application Laid-Open No. 3-54220). Is not preferred. Also, the obtained resin was not necessarily transparent.

Further, a composition obtained by adding 1 to 50% by weight of a rubbery polymer to a thermoplastic saturated norbornene-based resin has improved adhesiveness to a metal. It has been known that a rubbery polymer having a small difference in the ratio can be used (Japanese Patent Application Laid-Open No. HEI 3-112646).
issue). However, when a large amount of the rubbery polymer is added to the thermoplastic norbornene-based resin, there is a problem that the glass transition temperature (Tg) decreases.

[0007]

SUMMARY OF THE INVENTION As a result of intensive studies, the present inventors have found that by dispersing a compounding agent as fine microdomains in a thermoplastic saturated norbornene-based resin, the adhesion to various paints and films can be improved. The present inventors have found that they can be improved and have good appearance such as transparency, and have completed the present invention.

Although not particularly limited, organic polymer compounds are preferable, and particularly, the glass transition temperature is 40.
A rubbery polymer having a temperature of not more than ° C is preferred. In addition, there are cases where the glass transition temperature of a block copolymerized rubbery polymer or the like is 2 or more. In this case, if the lowest glass transition temperature is 40 ° C or lower, the glass transition temperature of the present invention is 40 ° C.
It can be used as the following rubbery polymer.

Examples include thermoplastic elastomers such as urethane-based thermoplastic elastomers, polyamide-based thermoplastic elastomers, 1,2-polybutadiene-based thermoplastic elastomers, vinyl chloride-based thermoplastic elastomers, and fluorine-based thermoplastic elastomers.

Among these, a copolymer of an aromatic vinyl monomer and a conjugated diene monomer, a hydrogenated product thereof,
In addition, the thermoplastic saturated norbornene-based resin of the present invention and the insoluble norbornene-based rubbery polymer have good dispersibility with the thermoplastic saturated norbornene-based resin, and are therefore preferable. The copolymer of the aromatic vinyl monomer and the conjugated diene monomer may be a block copolymer or a random copolymer. From the viewpoint of weather resistance, those in which a portion other than the aromatic ring is hydrogenated are more preferable. Specifically, styrene / butadiene block copolymer, styrene / butadiene / styrene / block copolymer, styrene / isoprene / block copolymer, styrene / isoprene / styrene / block copolymer, and hydrogenated products thereof And styrene / butadiene / random copolymer.

Further, the compounding agent of the present invention has a difference from the refractive index of the thermoplastic saturated norbornene resin to which it is added, preferably 0.02 or less, more preferably 0.015 or less,
Particularly preferably, it has a refractive index of 0.01 or less. Mixing those having a large difference in refractive index tends to be opaque when added in a large amount. Different types of thermoplastic saturated norbornene resins have different refractive indices.For example, rubbery polymers change the ratio of monomers or change the number of unsaturated bonds in the main chain by hydrogenation, etc. It is possible to change the refractive index continuously.
It is preferable to select a rubbery polymer having an appropriate refractive index according to the refractive index of the thermoplastic saturated norbornene resin used.

(Addition) In the present invention, a compounding agent is added to a thermoplastic saturated norbornene resin in an appropriate amount to form microdomains in the thermoplastic saturated norbornene resin and dispersed. If the addition amount is too large, the glass transition temperature of the resin composition is greatly reduced, and microdomains are not formed or aggregated, so that they are not dispersed. If the amount is too small, the effects of the present invention cannot be obtained. For example, when a rubbery polymer is used as a compounding agent, the compounding agent as a rubbery polymer is 0.001 to 0.8 parts by weight, preferably 0 to 100 parts by weight of a thermoplastic saturated norbornene resin. .003-
0.6 parts by weight, more preferably 0.005 to 0.4 parts by weight.

The method of addition is not particularly limited as long as the compounding agent forms microdomains in the thermoplastic saturated norbornene resin and is sufficiently dispersed. For example, when a rubbery polymer is used as a compounding agent, a mixer, a method of kneading the resin temperature in a molten state with a twin-screw kneader, or the like, a coagulation method by dissolving and dispersing in an appropriate solvent, a casting method, or There is a method of removing the solvent by a direct drying method.

In the case of kneading, the resin temperature is Tg + 50
A sufficient share is applied at a temperature of from C to Tg + 150C.
If the resin temperature is too low, the viscosity becomes high and kneading is difficult. If it is too high, the resin and the rubbery polymer deteriorate, and the two cannot be kneaded well due to differences in viscosity and melting point.

For example, Labo Plastomill (manufactured by Toyo Seiki)
Is used, the rotational speed is set to 20 in the two-axis different direction mixer mode.
At 30 rpm, the feed rate is adjusted and the residence time is about 1 to 10 minutes. If kneading is performed, the rubbery polymer is usually 0.3 μm in diameter in a thermoplastic saturated norbornene resin.
m or less micro domains can be formed and dispersed. Usually, in a twin-screw kneader, L / D is 25 or more, preferably 30 or more, and the residence time is about 1 to 10 minutes. The longer the residence time, the easier it is to form microdomains, but the more easily the resin and rubbery polymer deteriorate,
Preliminary kneading must be performed according to the combination of the resin, the rubbery polymer to be used, and the apparatus used for kneading, and the number of revolutions, residence time, and the like according to the combination must be determined.

When the rubbery polymer is used as a compounding agent, the microdomains are substantially spherical, and the variation in particle diameter among the particles is small. Usually, the diameter is 0.3 μm or less, preferably 0.2 μm or less. With this particle size, the decrease in the transparency of the thermoplastic saturated norbornene-based resin composition due to the addition of the rubbery polymer is small as described below, and does not pose a problem. In the case of other compounding agents as well, the microdomains are preferably substantially spherical, and it is preferable that there is no variation in particle diameter between particles, and the diameter is 0.3 μm or less, particularly 0.2 μm or less.
It is preferable that the thickness be not more than μm. In addition, even when the microdomain does not become spherical, the diameter of the smallest sphere that can confine the microdomain is 0.3 μm or less,
In particular, the thickness is preferably 0.2 μm or less.

(Additives) Various additives may be added to the thermoplastic saturated norbornene resin used in the present invention, if desired. Additives used in the resin are compatible with the resin, and include phenol-based and phosphorus-based antioxidants, antistatic agents, ultraviolet absorbers, and the like. When the sheet is formed by the solution casting method, it is also preferable to add a leveling agent to reduce the surface roughness. Leveling agent,
For example, a fluorine-based nonionic surfactant, a special acrylic resin-based leveling agent, a coating-based leveling agent such as a silicone-based leveling agent can be used, and among them, those having good compatibility with a solvent are preferable, and the amount added is usually Is 5 to 50,000 ppm, preferably 10 to 20,000 ppm.
It is 0 ppm.

(Thermoplastic Saturated Norbornene Resin Composition) In the thermoplastic saturated norbornene resin composition of the present invention, a compounding agent is usually 0.3 μm or less in diameter, preferably 0 μm or less, in a matrix of thermoplastic saturated norbornene resin. .
Microdomains of 2 μm or less are formed and dispersed.
The wavelength of monochromatic light used for information processing in information disks and infrared sensors is about 300 nm to 1000 nm, and visible light visible to humans is about 400 nm to 800 nm. The diameter of the compounding agent is smaller than the wavelength of these lights,
If microdomains of 0.3 μm or less, particularly 0.2 μm or less are formed, light is not easily scattered, and thus the thermoplastic saturated norbornene-based resin composition is excellent in transparency.

The transparency of the resin composition of the present invention varies depending on the refractive index, the amount of addition, the diameter of the microdomain, the dispersion state, etc. of the rubbery polymer. The light transmittance at 700 nm is 50% or more, and by adjusting the refractive index, the added amount, and the dispersion state,
It can be 80% or more, and even 90% or more.

It has excellent adhesion to a reflection film, a magneto-optical recording film made of a Tb-Fe-Co alloy, or the like.

The resin composition of the present invention is more excellent in moisture resistance at high temperatures than a thermoplastic saturated norbornene-based polymer. Thermoplastic saturated norbornene-based polymer is excellent in heat resistance and moisture resistance, but the molded product is, for example,
In a high-temperature and high-humidity treatment such as steam sterilization at 121 ° C. by an autoclave, transparency sometimes decreased. On the other hand, in the molded article of the resin composition of the present invention, substantially no decrease in transparency is observed.
