Description

  The present invention relates to decorative paper.

  For example, if water is also applied to coated paper (see Patent Document 1) in which a coating layer is formed on a base film, or simple paper, it can be attached (attached) to a glass plate. However, when the coated paper is peeled off from the glass plate, a part of the coated layer remains on the glass plate and the glass plate becomes dirty. On the other hand, even if paper is to be peeled off from a glass plate, it cannot be peeled cleanly and cannot be reused.

  The decorative paper 1 shown in FIG. 1 is composed of a porous biaxially stretched film. For this reason, the surface (one surface) 11 has minute irregularities based on the porosity, and the surface 11 has appropriate writing properties due to the presence of these irregularities. Further, if an erasable writing instrument is used, pictures, characters and the like can be repeatedly written on the surface 11 of the decorative paper 1. On the other hand, the back surface (the other surface) 12 also has minute irregularities based on the porosity, and the presence of the irregularities exhibits adherence to the adherend when water is applied to the back surface 12.

The biaxially stretched film may be opaque (opacity: 99% or more), but is preferably translucent. By using a translucent biaxially stretched film, the appearance is particularly improved when the adherend is a glass plate.
The opacity of the translucent biaxially stretched film is preferably about 50 to 80%, more preferably about 60 to 70%.

Moreover, it is preferable that the thickness of a biaxially stretched film is about 100-300 micrometers, and it is more preferable that it is about 150-250 micrometers. A biaxially stretched film having such a thickness can prevent the decorative paper 1 from being unintentionally broken and difficult to handle.
From the viewpoint of improving the handleability of the decorative paper 1, it is preferable that the biaxially stretched film has an appropriate rigidity.

The rigidity in the MD direction of the biaxially stretched film is preferably about 1 to 20 kN / m, more preferably about 5 to 15 kN / m.
On the other hand, the stiffness in the CD direction of the biaxially stretched film is preferably about 10 to 50 kN / m, more preferably about 20 to 40 kN / m.

Further, the two density of biaxially stretched film is preferably 0.8~1.1g / cm ³ or so, more preferably 0.9~1g / cm ³ order.
Furthermore, the porosity of the biaxially stretched film is preferably about 15 to 60%, more preferably about 25 to 45%.

The decorative paper 1 is composed of only a biaxially stretched film even if it has a multilayer structure. The biaxially stretched film is already stretched in the biaxial direction as a whole. For this reason, the biaxially stretched film has high bending elasticity in the biaxial direction and is difficult to crease.
Such a biaxially stretched film is made of a material containing a thermoplastic resin and white particles. The opacity and hue of the biaxially stretched film can be adjusted by the type and amount of white particles.

  A thermoplastic resin is a component which forms the matrix of a biaxially stretched film, The kind in particular is not restrict | limited. Examples of the thermoplastic resin include ethylene resins (high density polyethylene, medium density polyethylene, etc.), propylene resins (polypropylene, etc.), cycloolefin copolymers (poly (4-methylpent-1-ene), ethylene-cyclic olefin copolymers. Olefin resins such as polymers); polyamide resins (nylon-6, nylon-6,6, nylon-6,10, nylon-6,12, etc.); ester resins (polyethylene terephthalate, polyethylene naphthalate, Polybutylene terephthalate, aliphatic polyester, etc.); Styrenic resin (atactic polystyrene, syndiotactic polystyrene, styrene-acrylonitrile copolymer, acrylonitrile-butadiene-styrene copolymer, etc.); polycarbonate; polyphenyle Sulfide, and the like. These can be used individually by 1 type or in mixture of 2 or more types.

  Among these, as a thermoplastic resin, it is preferable to use an olefin resin, it is more preferable to use a propylene resin and a high density polyethylene, and it is more preferable to use a propylene resin. By using these thermoplastic resins, productivity, ease of processing, water resistance, chemical resistance, and recyclability of the biaxially stretched film can be improved, and costs can be reduced.

Propylene-based resins include propylene homopolymers such as polypropylene exhibiting isotactic, syndiotactic or other stereoregularity, propylene and α-olefins as main components (ethylene, butene-1, hexene-1, A copolymer with heptene-1,4-methylpentene-1, etc.) can be used.
The amount of the thermoplastic resin contained in the biaxially stretched film is preferably about 44 to 89% by weight, and more preferably about 50 to 86% by weight. Thereby, a biaxially stretched film having sufficient strength and porosity can be obtained.

Examples of the constituent material of the white particles include calcium carbonate, titanium oxide, silicon oxide, barium sulfate, aluminum sulfate, magnesium oxide, aluminum oxide, and zinc oxide. Among these, as a constituent material of the white particles, at least one of calcium carbonate and titanium oxide is preferable. When two types of calcium carbonate and titanium oxide are used as the constituent material of the white particles, for example, calcium carbonate white particles and titanium oxide white particles can be used in combination.
The amount of white particles contained in the biaxially stretched film is preferably about 11 to 56% by weight, and more preferably about 14 to 50% by weight.

  For biaxially stretched films, optical brighteners, heat stabilizers, antioxidants, UV stabilizers (light stabilizers), UV absorbers, dyes, pigments, dispersants, lubricants, antistatic agents are optionally used. An anti-blocking agent, an anti-blocking agent, a flame retardant, etc. may be mixed.

The biaxially stretched film used in the present invention may have a single layer structure or a laminated structure in which two or more layers are laminated.
As an example of a laminated structure, for example, a two-layer structure including a base material layer and a surface layer having a surface 11 laminated on one side of the base material layer, the base material layer, and the both sides of the base material layer are laminated. And a three-layer structure having a front surface layer having a front surface 11 and a back surface layer having a back surface 12.
Furthermore, it can also be set as the laminated structure of 4 or more layers provided with the intermediate | middle layer laminated | stacked between the surface layer and the base material layer. Therefore, for example, as a biaxially stretched film having a three-layer structure, a configuration of surface layer / base material layer / back surface layer, and as a configuration of a biaxially stretched film having a five-layer structure, surface layer / intermediate layer / base material layer / The configuration of the intermediate layer / back surface layer can be exemplified.

  The lamination method is not particularly limited. For example, a method in which a resin melted by a plurality of extruders is led to a single die by a feed block or a multi-manifold (coextrusion), and lamination is performed by melt extrusion lamination. (Melting laminating) and the like.

  In addition, as a stretching method, for example, a molten resin is extruded into a sheet shape using a T die or an I die connected to a screw type extruder, and then the sheet is used for the difference in peripheral speed of the roll group. A method of stretching by sequential biaxial stretching combining longitudinal stretching and lateral stretching using a tenter oven, a method of stretching by simultaneous biaxial stretching using a combination of a tenter oven and a linear motor, and pantograph type stretching by cutting the sheet Examples thereof include a method of simultaneous biaxial stretching using an apparatus.

The stretching temperature varies depending on the type of the thermoplastic resin to be used and is not particularly limited, but is preferably 2 to 60 ° C. lower than the melting point of the thermoplastic resin. For example, when the thermoplastic resin is a propylene homopolymer (melting point: 155 to 167 ° C.), the stretching temperature is preferably about 152 to 164 ° C., and the thermoplastic resin is high-density polyethylene (melting point 121 to 134 ° C.). When it is, it is preferable that extending | stretching temperature is about 110-120 degreeC.
The stretching speed is preferably about 20 to 350 m / min.

The decorative paper 1 shown in FIG. 1 is in the shape of a terutan shaved (predetermined figure). It may be a shape. In addition, a predetermined shape may be cut out from the square or rectangular decorative paper 1 before use.
Examples of the adherend to which the decorative paper 1 is attached include a glass plate (window glass), a wall surface of a bathroom, a mirror surface of a bathroom, etc., and a glass plate is preferable. The interior of the room can be decorated by writing pictures, characters, etc. on the decorative paper 1 and pasting them on the window glass.

Next, a method of using the decorative paper 1 will be described with reference to FIGS.
First, a favorite picture or character is written on the surface 11. At this time, if an erasable writing instrument is used, pictures, characters and the like can be repeatedly written on the surface of the decorative paper 1.
Next, by applying water to the back surface 12, the adherence is developed and is attached to the window glass (see also FIG. 3).
On the other hand, when the decorative paper 1 is peeled from the adherend, a part thereof can be removed cleanly without remaining on the adherend.

As mentioned above, although the decorative paper of the present invention has been described, the present invention is not limited to this, for example, each part constituting the decorative paper can be replaced with a configuration that exhibits the same function, Arbitrary configurations may be added.
For example, in the embodiment, the case where a biaxially stretched film is used as a film has been described as a representative, but an unstretched film or a uniaxially stretched film can also be used as the film.
