2. Description of the Related Art Conventionally, soft transparent resins have been used for building materials, household product materials, automobile members, electronic / electrical related parts, various window / windshield members, sports / leisure related materials, shatterproof materials, various films / sheets. It is widely used in many other fields such as timber. In particular, in recent years, by laminating a film made of a soft transparent resin on various base materials, the purpose is to impart scratch resistance, anti-scattering property, etc. For the purpose of imparting, the use of a soft transparent resin as a soft coat has been attempted in a new field. However, since soft resins are prone to bacterial, mold, yeast, and algae microbe growth, resin deformation, decomposition, and other deterioration, and aesthetic stains may occur. It has a drawback that it is difficult to use in a place exposed to moisture.

On the other hand, although some soft resins having antibacterial and antifungal properties have been proposed, an antibacterial and antifungal soft resin having transparency, self-healing property, scratch resistance and flexibility. However, the development was desired.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, to be essentially transparent, to have self-repairing property and scratch resistance, and to have antibacterial property and antifungal property. The present invention provides a film made of the novel soft resin and a laminate thereof.

[0005]

The present invention contains an antibacterial or antifungal agent in an amount of 0.01 to 10% by weight based on the total weight of the resin.
It is intended to provide an antibacterial / mildew-proof film which is essentially transparent and is made of a soft resin having self-healing property and scratch resistance, and a laminate formed by laminating the film on a substrate.

The content of the antibacterial agent or antifungal agent is 0.01 to 10% by weight based on the total weight of the resin.

The essentially transparent soft resin having self-healing property and scratch resistance in the present invention includes polyurethane resin, acrylic transparent rubber-like resin, silicone rubber-like resin, olefin-based or styrene-based elastomer, A blended product of the same or other resins, a polymer alloy, or the like can be used, but a polyurethane resin is most preferable from the viewpoint of the balance of transparency, self-healing property, and scratch resistance.

The film must be made of only this specific soft resin or have a layer made of that material as one surface layer. The film of the present invention may further have one or more synthetic resin layers or the like, and particularly may have an adhesive or pressure-sensitive adhesive layer. Further, the other layers may be partially present (for example, only in the peripheral portion). Preferably,
The film of the present invention consists only of a specific soft synthetic resin,
When laminating on a base material, it is laminated using an adhesive, a pressure sensitive adhesive, a double-sided adhesive (or adhesive) tape, or the like. Further, when the surface of the film of the present invention itself has a certain degree of tackiness or adhesion, the film can be laminated only.

The thickness of the film in the present invention needs to be 0.05 mm or more so that sufficient self-repairing property can be obtained. Further, it is not preferable in terms of cost to make the thickness too thick, so that the thickness is preferably 2 mm or less.

The surface of the specific soft synthetic resin layer may have fine irregularities called so-called embossing. This embossing is effective for antireflection. Further, the film of the present invention may be colored or may be patterned by printing or the like as long as it is essentially transparent. Further, a thin colored film or a patterned film may be laminated. The film of the present invention may have electrostatic properties.

The present invention will be described below in the case where the film of the present invention is made of only a specific soft synthetic resin (hereinafter, simply referred to as soft synthetic resin), but the present invention is not limited to this.

The reactive casting method is a method in which a fluid reactive raw material mixture which reacts to form a soft synthetic resin is cast on a flat peelable carrier and reacted to form a thin layer of the soft synthetic resin. Then, the film or sheet is obtained by peeling from the carrier. When carrying out the reactive casting method, the reactive raw material may contain a solvent, but in the case of a polyurethane resin, a method using a reactive raw material containing substantially no solvent, that is, a reactive bulk casting method is more preferable. preferable.

The transparent, self-repairing and scratch-resistant non-yellowing polyurethane resin obtained by the reactive casting method includes linear resins (thermoplastic resins) and cross-linking resins (thermosetting resins). Any of these is possible, but a crosslinkable resin is more preferable from the viewpoint of chemical resistance, stain resistance, durability and the like.

The cross-linkable polyurethane resin is a compound in which at least one of at least one of the reactive main raw materials composed of a polyfunctional active hydrogen compound (polyol etc.) and polyisocyanate is trifunctional or more. Is a polyurethane resin obtained by using. On the other hand, all thermoplastic polyurethane-based resins are polyurethane-based resins obtained by using bifunctional raw materials.

The urethane-based resin obtained by the reactive casting method is formed into a film by casting a reactive raw material mixture obtained by mixing an active hydrogen compound such as a polyol and a chain extender and a polyisocyanate onto a base material and curing it. I will get it. As the polyol, polyether-based, polyester-based, polycarbonate-based, etc. can be used, but polyester-based polyols are preferable from the viewpoint of balance of durability, price, strength, scratch resistance and self-healing property. The number of functional groups is required to be larger than 1 as an average value, but it is preferably 2 to 3 from the viewpoint of the balance of strength, elongation, self-healing property and scratch resistance. If necessary, a chain extender can be used, and as the chain extender, a short chain polyol, a short chain polyamine or the like can be used. From the viewpoint of transparency and flexibility, short chain diols are preferable.

As the polyisocyanate, aromatic diisocyanate, aromatic polyisocyanate, aliphatic diisocyanate, aliphatic polyisocyanate, alicyclic diisocyanate, alicyclic polyisocyanate and the like can be used, but from the viewpoint of durable yellowing. Aliphatic or alicyclic diisocyanates or polyisocyanates are preferred.

These raw materials can be used alone or as a mixture. In addition, if necessary UV absorber
It is also possible to add stabilizers such as antioxidants and light stabilizers, urethanization catalysts, extenders, colorants, flame retardants, antistatic agents and other additives.

Further, these raw materials can be used by diluting them with a solvent or dissolving them, and a curing agent may be added depending on the case. A preferred cross-linkable polyurethane resin has an average hydroxyl value of 100 to 500, especially 15
It is a cross-linkable polyurethane-based resin obtained by reacting at least a part of a trifunctional or higher functional polyol of 0 to 400 with a non-yellowing modified polyisocyanate having an average functional number of 2 or more.
The polyol is preferably triol alone (may be a mixture of two or more triols) or a mixture of triol and diol. The hydroxyl value of each polyol is not particularly limited, but the average hydroxyl value of all polyols is 200 to 4
00 is more preferable. This polyol may contain the above-mentioned chain extender which is a short-chain polyol, and the average hydroxyl value is the average hydroxyl value calculated including this.
