Brief description of the drawings

FIG. 1 is a sectional view schematically showing an example of a decorative film of the present invention. MODE FOR CARRYING OUT THE INVENTION

[0017] The decorative film of the present invention is a decorative film having a base film, a thermoplastic resin layer and a top coating layer in that order, wherein the top coat layer contains urethane particles containing silica particles and resin beads. The resin beads are characterized by containing at least one of acrylic beads and urethane beads. In the present specification, “film” has the same meaning as “sheet”, and the two are not distinguished by the thickness. Also, base film and thermoplastic 〇 2020/175628 3 (:171? 2020/008062

A printing layer (ink layer), a primer layer (adhesive layer), and the like may be disposed between the resin layer and the thermoplastic resin layer, and between the thermoplastic resin layer and the topcoat layer.

[0018] Fig. 1 is a cross-sectional view schematically showing an example of the decorative film of the present invention. The decorative film 10 shown in FIG. 1 has a structure in which a top coat layer 1, a thermoplastic resin layer 2, a printing layer 3, a base film 4, and an adhesive layer 5 are laminated in this order. By adhering the adhesive layer 5 to the base material, the decorative film 10 can be attached to the base material. As a result, the base material is covered with the decorative film 10, and the top coating layer 1 constitutes the surface in contact with the space.

[0019] [Top coat layer]

The top coat layer 1 is located on the outermost surface of the decorative film 10. The urethane resin contains silica particles and resin beads. The inclusion of silica particles can impart matte properties, and the inclusion of resin beads can impart a rough texture. Further, it has scratch resistance (wear resistance) due to the use of urethane resin, and the addition of silica particles improves the hardness of the top coat layer 1 to further improve the scratch resistance. .. In particular, the decorative property of the decorative film 10 can be greatly enhanced by giving the topcoat layer 1 more matte and touch feeling in accordance with the pattern of the printing layer 3. The pattern of the printing layer 3 used to enhance the decorative properties of the decorative film 10 includes, for example, a design that reproduces the surface condition of a material other than resin such as wood, earthen wall, and concrete. In the past, it was difficult to achieve both matteness and durability, but with the topcoat layer 1 having the above-mentioned configuration, matteness and durability can be achieved at the same time. It is possible to prevent a change in gloss and a decrease in the matte property when the decorative film 10 is applied (when it is attached to the base material).

The urethane resin is not particularly limited, but a thermoplastic urethane resin is preferable, and a silicone copolymer type polyurethane resin is particularly preferable. If a thermoplastic urethane resin is used, embossing can be performed after the top coat layer 1 is formed, making it possible to produce decorative films 10 with various designs. 〇 2020/175628 4 卩 (：171? 2020 /008062

Is. Further, by using the silicone copolymer type polyurethane resin, it is possible to have particularly excellent antifouling property (fingerprint adhesion preventing property) and scratch resistance. In addition, the silicone copolymer polyurethane resin film gives a smooth hand feeling, but by including acrylic beads and urethane beads in the top coat layer 1, it is possible to give a desired rough feel. it can

[0021] The silica particles may be particles composed of silicon dioxide, and their shape and average particle size are not particularly limited. The average particle size of the silica particles is preferably 0.1 or more, and more preferably 0.81 or more, from the viewpoint of imparting matting properties. If the addition amount is the same, the smaller the average particle size is, the higher the matting property can be imparted. Further, the average particle diameter of the silica particles is preferably 10 or less, more preferably less than 7, and further preferably 2 or less from the viewpoint of preventing the transparency of the top coat layer 1 from being lowered. preferable. If the transparency of the top coat layer 1 is too low, the visibility of the pattern provided by the print layer 3 will be low, and the design of the decorative film 10 will be impaired. Further, in the decorative film 10 on which the printing layer 3 is not provided, the visibility of the colored thermoplastic resin layer 2 is reduced, and the designability of the decorative film 10 is impaired. As the silica particles, it is possible to use commercially available products such as “S993 Series” manufactured by Sakai Chemical Industry Co., Ltd. and “Mizukasil” manufactured by Mizusawa Chemical Industry Co., Ltd.

[0022] The content of silica particles in the top coat layer 1 is preferably 1 part by weight or more based on 100 parts by weight of the resin solid content from the viewpoint of imparting a matting property. It is more preferably at least 10 parts by weight, still more preferably at least 10 parts by weight. Further, the content of silica particles should be 30 parts by weight or less with respect to 100 parts by weight of the resin solid content from the viewpoint of preventing the transparency of the top coat layer 1 from decreasing and the haze from increasing excessively. Is preferable, and 20 parts by weight or less is more preferable.

[0023] The resin beads are at least one of acrylic beads and urethane beads. 〇 2020/175628 5 units (: 171-1?2020/008062

Including. The acrylic beads may be particles containing an acrylic resin component, and their shape and average particle size are not particularly limited. The urethane beads may be particles containing a urethane resin component, and their shape and average particle size are not particularly limited. With acrylic beads and urethane beads, it is possible to reproduce the feel of wood, earthen walls, or concrete. In addition, as a method of giving a feeling of touch, it is possible to add inorganic beads made of an inorganic material such as glass beads, but acrylic beads and urethane beads are used as the urethane resin which is the main material of the urethane coating layer 1. Since they have excellent adhesion and compatibility with each other and have a close specific gravity, they have the advantage that they are less likely to fall off the top coat layer 1 or settle to the bottom of the top coat layer 1 than inorganic beads. As the acrylic beads, commercially available products such as "Chemnow (registered trademark)" manufactured by Soken Chemical Industry Co., Ltd., "Atopal" manufactured by Negami Kogyo Co., Ltd., and "Gantz Pearl" manufactured by Aikae Industry Co., Ltd. may be used. it can.

[0024] The average particle size of the resin beads is preferably 1 or more, more preferably 5 or more, and further preferably 10 or more, from the viewpoint of giving a feeling of touch. Further, the average particle size of the resin beads is preferably 50 or less, more preferably 30 or less, from the viewpoint of workability and prevention of dropping from the top coat layer 1. The texture that can be obtained can be adjusted depending on the particle size of the resin beads, and if small beads (10 or less) are used, a dry feel and a fine grain feel can be obtained, and a feel similar to that of concrete can be obtained. The use of large beads (10 to 30) gives a gritty feel, and gives the feel of a clay wall or wood chips. If you use larger beads (more than 30), you can get the feel of rough wood.

[0025] The content of the resin beads in the top coat layer 1 is preferably 10 parts by weight or more based on 100 parts by weight of the resin solid content from the viewpoint of giving a touch feeling. If the amount is less than 10 parts by weight, a sufficient amount of the resin beads may not be distributed on the surface of the top coat layer 1 and a foreign substance may be felt. 10 to 20 parts by weight 〇 Within the range of 2020/175628 6 (:171? 2020/008062), the surface irregularities of the top coat layer 1 are clearly visible. Within the range of 20 to 30 Judo, the surface of the top coat layer 1 is Since the resin beads are densely distributed, the feeling of roughness is suppressed, and the feel of the material is reduced.The content of resin beads is 30 parts by weight or less based on 100 parts by weight of the resin solid content. If it exceeds 30 parts by weight, the frequency of overlapping of the resin beads increases, which may increase the number of resin beads that fall off the surface of the top coat layer 1.

[0026] The thickness of the top coat layer 1 is not particularly limited, but is preferably 1 to 10.

[0027] The top coat layer 1 preferably has high transparency in order to further enhance the design of the printed layer 3, and specifically, the total light transmittance is preferably 70% or more, It is more preferably at least 80% and even more preferably at least 90%.

That is, the thermoplastic resin layer 2 may be what is generally called a polyvinyl chloride film (O film). The thermoplastic resin layer 2 has a role of protecting the surface of the printed layer 3 and preferably has high transparency.

[0030] Examples of the vinyl chloride resin include homopolymers of vinyl chloride and copolymers of vinyl chloride and other monomers. 〇 2020/175628 7 卩(：171? 2020/008062

The content of the above-mentioned other monomer in the copolymer is usually 50% by weight or less, and preferably 10% by weight or less. If it exceeds 50% by weight, the flex resistance may decrease. Among the above vinyl chloride resins, a vinyl chloride homopolymer is preferable from the viewpoint of obtaining dimensional stability.

[0033] The average degree of polymerization of the vinyl chloride resin is not particularly limited, and is adjusted according to the required hardness of the film and the amount of the plasticizer used for adjusting the hardness, and for example, 750 It is said to be about 1300. The preferable upper limit of the average degree of polymerization is 105. When the average degree of polymerization is in the range of 750 to 130, the moldability at a relatively low temperature is particularly good. In the present specification, the average degree of polymerization of the vinyl chloride resin means the average degree of polymerization measured in accordance with "" 3 [< 6 7 2 1 "Test method for vinyl chloride resin".

[0034] The thermoplastic resin layer 2 may contain a plasticizer. The plasticizer is not particularly limited, and those conventionally blended with vinyl chloride resin can be used.

The content of the plasticizer is preferably 10 to 30 parts by weight with respect to 100 parts by weight of the vinyl chloride resin. When the content is less than 10 parts by weight, the thermoplastic resin layer 2 becomes too hard, which may lower the moldability and may break the film during molding. On the other hand, if the amount exceeds 30 parts by weight, the thermoplastic resin layer 2 becomes too soft, resulting in a decrease in strength. A more preferable lower limit of the content of the plasticizer is 15 parts by weight.

[0037] The thermoplastic resin layer 2 is an additive such as a stabilizer, an ultraviolet absorber, a colorant, a foaming agent, a lubricant, a modifier, a filler such as inorganic particles or inorganic fibers, and a diluent, if necessary.

[0039] When the stabilizer is contained, its content is preferably 0.3 to 5.0 parts by weight with respect to 100 parts by weight of the thermoplastic resin. When the above ultraviolet absorber is contained, its content is 0.3 to 2 parts by weight per 100 parts by weight of the thermoplastic resin.

0 parts by weight is preferred.

[0040] The thickness of the thermoplastic resin layer 2 is not particularly limited, but is preferably 40 to 200. If the thickness is less than 40, the designability may deteriorate. On the other hand, if the thickness exceeds 200, the total calorific value of the decorative film 10 may increase. The more preferable lower limit of the thickness of the thermoplastic resin layer 2 is 50, and the more preferable upper limit thereof is 150.

[0041] The thermoplastic resin layer 2 preferably has high transparency in order to further enhance the designability of the printed layer 3, and specifically, the total light transmittance is preferably 80% or more. , 90% or more is more preferable.

[0042] [Printing layer]

The print layer 3 is a decorative layer containing a dye or a pigment. By arranging the print layer 3, it is possible to enhance the design of the decorative film 10. The printing layer 3 may be a colored film in which a dye or a pigment is added to the resin composition, or may be a character or pattern printed on at least a part of the surface of the film made of the resin composition. Good. The dye or the pigment is not particularly limited, and those usually used in the field of cosmetic film can be used.

[0043] Examples of the resin composition used for the printed layer 3 include vinyl esters such as vinyl chloride, vinyl acetate, and vinyl propionate; olefins such as ethylene, propylene, and styrene; methyl acrylate, ethyl acrylate, methacryl (Meth)acrylic acid ester such as methyl acid ester; dibutyl maleate, gestyl maleate such as gestyl maleate; dibutyl fumarate, gestyl fumarate such as tylyl fumarate; vinyl cyanide such as acrylonitrile and methacrylonitrile; chloride Vinylidene, vinyl halides such as vinyl bromide; methylbi 〇 2020/175628 10 units (：171? 2020/008062

[0044] [Base film]

The base film 4 has a role as a support for the decorative film 10 and also has a role as a base material for the printing layer 3.

[0045] The material of the base film 4 is not particularly limited, and examples thereof include vinyl chloride resin and polyethylene terephthalate resin, and among them, it is preferable to contain the vinyl chloride resin. Since vinyl chloride resin has high flame retardancy, it is possible to suppress an increase in the total calorific value by using it as a support for the decorative film 10. The vinyl chloride resin in the base film 4 may be the same as or different from the vinyl chloride resin used in the thermoplastic resin layer 2 in terms of composition and average molecular weight.

The content of the plasticizer used in the base film 4 is preferably 10 to 30 parts by weight with respect to 100 parts by weight of the vinyl chloride resin. If the content is less than 10 parts by weight, the base film 4 becomes too hard, and the film may be broken during molding. On the other hand, if the amount exceeds 30 parts by weight, the base film 4 becomes too soft, which may make it difficult to form the printing layer 3 on the base film 4. A more preferable lower limit of the content of the plasticizer is 15 parts by weight. Since the thermoplastic resin layer 2 and the base film 4 are laminated, it is preferable that they have basically the same hardness. Therefore, if both the thermoplastic resin layer 2 and the base film 4 are made of vinyl chloride resin and have the same thickness, it is preferable that the plasticizer content is also the same.

[0048] The base film 4 is a stabilizer, an ultraviolet absorber, a coloring agent, a foaming agent, if necessary. 〇 2020/175628 1 1 卩(: 171-1?2020/008062

It may contain additives such as agents, lubricants, modifiers, fillers such as inorganic particles and inorganic fibers, and diluents. These additives may be the same as or different from the additives in the thermoplastic resin layer 2. Since the base film 4 is disposed below the ink layer 3, even if an additive is added to the base film 4, the change in color tone of the decorative film 10 caused by the additive is hard to be visually recognized. Therefore, the base film 4 is suitable for adding an additive for adjusting the characteristics of the entire decorative film 10, and may include, for example, a flame retardant.

[0049] The thickness of the base film 4 is not particularly limited, but it is preferably 40 to 200 0.01. If the thickness is less than 40, the decorative film 10 may be too flexible and the workability may be lowered, or the weather resistance may be lowered.

The adhesive layer 5 contains an adhesive. Examples of the pressure-sensitive adhesive include acrylic pressure-sensitive adhesives, rubber pressure-sensitive adhesives, silicone pressure-sensitive adhesives, and the like. Among them, acrylic adhesives are preferably used because they are excellent in tackiness, heat resistance, heat aging resistance, moisture aging resistance, and weather resistance and are relatively inexpensive.

[0052] The acrylic pressure-sensitive adhesive is a pressure-sensitive adhesive containing an acrylic polymer. Examples of the acrylic polymer include a homopolymer of (meth)acrylic acid alkyl ester or a copolymer thereof.

For the adhesive layer 5, for example, an adhesive composition containing an adhesive, a crosslinking agent (curing agent), etc. is applied on a support to form a coating film, and then the coating film is dried by heating. Therefore, it can be formed by a method of curing. The cross-linking agent (curing agent) is a compound that cross-links by chemically reacting or interacting with the functional group in the pressure-sensitive adhesive. The above bridge 〇 2020/175628 12 boxes (：171? 2020/008062

As the agent, a known crosslinking agent such as an isocyanate curing agent or an epoxy curing agent can be used.

In other words, it is preferable application amount of the adhesive composition of the adhesive layer 5 is dried is 5 to 9 0 ^9/2. A more preferred lower limit of the coating amount is 1 〇 9 / | a 11 ^2. The more preferable upper limit of the coating amount is 60 9

It is ² .

[0056] The thickness of the adhesive layer 5 is preferably 10 to 60. If the above thickness is less than 10, it may not be possible to obtain sufficient tackiness. On the other hand, if the thickness exceeds 60, the total calorific value of the decorative film 10 may increase. The more preferable lower limit of the thickness of the adhesive layer 5 is 20 and the more preferable upper limit thereof is 50. The thickness of the adhesive layer 5 is the thickness after drying.

[0057] [Separator]

The decorative film 10 may be provided with a separator on the side of the adhesive layer 5 opposite to the base film 4. By providing the above-mentioned separator, it is possible to prevent the adhesive layer 5 from being exposed during the production, transportation, and storage of the decorative film 10, prevent the adhesive layer 5 from deteriorating, and improve the handleability of the decorative film 10. The separator may be peeled off just before being attached to the substrate.

[0058] The separator is not particularly limited, and those generally used in the field of decorative films can be used. The separator is preferably one that can be easily peeled off without damaging the adhesive layer 5, and examples thereof include a resin film (release film), paper (release paper), and a laminated film of paper and a coating layer. Examples of the release film include resin films such as polyester, polyvinyl chloride, polyvinylidene chloride, polyethylene terephthalate and polypropylene. The resin film has a silicone resin or 〇 2020/175 628 13 卩 (：171? 2020 /008062

It is preferable that the easy peeling treatment is performed by applying a fluorine resin or the like. Examples of the release paper include high-quality paper and glassine paper.

The surface of the decorative film 10 on the side of the top coat layer 1 may be subjected to surface treatment such as embossing, if necessary. By giving an embossed shape (irregular shape) to the surface of the decorative film 10 by embossing, the visual and tactile sensations can be further improved. The embossing process may be performed on the surface of the top coat layer 1 or may be performed on the surface of the thermoplastic resin layer 2 before forming the top coat layer 1. When the top coat layer 1 is composed of a thermoplastic urethane resin, embossing can be performed after the top coat layer 1 is formed, so that it is possible to produce decorative films 10 of various designs. Is.

[0060] The decorative film 10 preferably has a total organic resin layer thickness of 100 to 500. If the total thickness is less than 100, workability may be reduced and weather resistance may be reduced. On the other hand, if the total thickness exceeds 500, it may be difficult to suppress the total amount of heat generation. The total thickness of the organic resin layer means the total thickness of the top coat layer 1, the thermoplastic resin layer 2, the printing layer 3, the base film 4, and the adhesive layer 5. The total thickness of the organic resin layer does not include the thickness of the separator. The more preferable lower limit of the total thickness of the organic resin layer is 120, and the more preferable upper limit thereof is 300!.
