  However, the technique disclosed in Patent Document 1 has a problem that it has poor solvent resistance and cannot withstand printing, coating processing, and the like. Moreover, in the technique disclosed in Patent Document 2, an adhesive is required when bonding an unstretched polyester film and a polyolefin-based resin film, and a complicated process is required. In addition, in the technique disclosed in Patent Document 3, there is no problem when the casing is made of metal because the processing temperature is high, but when the casing is made of resin, the heat resistance is inferior, so in the decoration process, Problems such as deformation of the housing and misalignment of the decoration occurred, which was not sufficient in terms of formability at low temperatures.

  The present invention has been made in view of the above circumstances, and the problem to be solved is to provide a decorative sheet and a laminated sheet for decoration that are excellent in workability, formability, and productivity, and in particular, low-temperature formability. An object of the present invention is to provide a decorative sheet and a decorative laminated sheet.

  According to the present invention, even when a molded product whose casing cannot withstand a high-temperature decoration process, for example, a decoration process under conditions at a low temperature of 80 to 125 ° C. is required, sheet loosening occurs. Therefore, it is possible to provide a decorative sheet and a decorative laminated sheet that have sufficient formability and are excellent in workability and productivity.

  Hereinafter, the present invention will be described in detail. However, the scope of the present invention is not limited to the embodiments described below. Unless otherwise specified, the notation “A to B” for numerical values A and B means “A to B”. In this notation, when a unit is attached to only the numerical value B, the unit is also applied to the numerical value A.

  The decorative sheet of the present invention contains a polypropylene resin (A) having a melting point of 110 ° C. or more and 140 ° C. or less and a polypropylene resin (B) having a melting point of 145 ° C. or more and 175 ° C. or less in a specific ratio. This can solve this problem.

<Polypropylene resin>
The polypropylene resin in the present invention includes a polypropylene resin polymerized using a Ziegler-Natta catalyst or a metallocene catalyst, and a propylene homopolymer (homopolypropylene) or a propylene copolymer is used. Can do.
Examples of the propylene copolymer include a block polypropylene resin, a random polypropylene resin, and a reactor type polypropylene thermoplastic elastomer. Moreover, these mixtures can also be used as a polypropylene resin.

  Further, as a copolymer of propylene, a random copolymer (random polypropylene) of propylene and ethylene or other α-olefin, a block copolymer (block polypropylene), a block copolymer containing a rubber component, or And graft copolymers. Other α-olefins copolymerizable with propylene are preferably those having 4 to 12 carbon atoms, such as 1-butene, 1-pentene, 1-hexene, 1-heptene, 1-octene, 4- Examples thereof include methyl-1-pentene and 1-decene, and one or a mixture of two or more thereof is used. Usually, the mixing ratio of the α-olefin is about 1 to 10% by weight with respect to propylene.

(Polypropylene resin (A))
The polypropylene resin (A) having a melting point of 110 ° C. or more and 140 ° C. or less used in the present invention is not particularly limited as long as it satisfies the melting point, but is preferably a random polypropylene resin, more preferably a metallocene catalyst. A metallocene random polypropylene resin obtained by polymerization using a Ziegler-Natta random polypropylene resin obtained by polymerization using a Ziegler-Natta catalyst, and more preferably a metallocene random polypropylene resin Resin.

  It is important that the polypropylene resin (A) used in the present invention has a melting point in the range of 110 ° C. or higher and 140 ° C. or lower, preferably in the range of 115 ° C. or higher and 135 ° C. or lower, and 118 ° C. or higher and 130 ° C. or lower. The following range is more preferable. By setting the melting point to 110 ° C. or higher, it is possible to suppress the slack of the decorative sheet during the decoration process or the process of forming the decoration layer. Further, by setting the melting point to 140 ° C. or less, the moldability at low temperatures can be improved.

(Polypropylene resin (B))
The polypropylene resin (B) having a melting point of 145 ° C. or higher and 175 ° C. or lower used in the present invention is not particularly limited as long as it satisfies the melting point, but a homopolypropylene resin and a block polypropylene resin are preferable, and more preferably. A homopolypropylene resin, more preferably a homopolypropylene resin having a long chain branch, can be used.

  The homopolypropylene resin having a long chain branch in the present invention is a polypropylene resin having a branched structure with a molecular chain consisting of several tens or more main chain carbon atoms and several hundred or more in molecular weight, such as 1-butene. A distinction is made from short chain branches of several carbons formed by copolymerization with α-olefins.

  The polypropylene resin having a long chain branch that can be used in the present invention preferably has a melt tension at 230 ° C. of 3 g or more and 25 g or less. By setting the melt tension to 3 g or more, the rigidity of the decorating sheet can be made preferable during the decorating process, the sagging can be suppressed, and wrinkling can be suppressed in the decorating sheet. Further, by setting the melt tension to 25 g or less, the dispersibility is lowered due to the difference in viscosity with respect to the polypropylene resin (A), the appearance of the decorative sheet is deteriorated, the rigidity is too high, and the moldability is lowered. Can be suppressed.

As a direct indicator that a polypropylene-based resin having a long chain branch has a branch, a branch index g ′ can be exemplified. g ′ is given by the ratio of the intrinsic viscosity [η] lin of the linear polymer having the same molecular weight as the intrinsic viscosity [η] br of the polymer having a long chain branched structure, that is, [η] br / [η] lin. When a long chain branched structure is present, the value is smaller than 1.
The definition is described in, for example, “Developments in Polymer Characterization-4” (JV Dawkins ed. Applied Science Publishers, 1983), and is an index well known to those skilled in the art.

For example, g ′ can be obtained as a function of the absolute molecular weight Mabs by using a GPC equipped with a light scatterometer and a viscometer as described below.
The polypropylene resin having a long chain branch used in the present invention preferably has a g ′ of 0.30 or more and less than 1.00, more preferably 0, when the absolute molecular weight Mabs determined by light scattering is 1,000,000. 0.55 to 0.98, more preferably 0.75 to 0.96, and most preferably 0.78 to 0.95.
Polypropylene resin having a long chain branch is considered to generate a comb chain as a molecular structure from the polymerization mechanism. When g ′ is less than 0.30, the main chain is few and the ratio of the side chain is extremely high. In such a case, the melt tension may not be improved or a gel may be formed, which is not preferable. On the other hand, when g ′ is 1.00, this means that there is no branch, and the melt tension tends to be insufficient.
