To provide a vinylidene-fluoride resin film having low cloudiness and good visibility of a pattern and the like of a decorative film of a lower layer although having a matte tone with low glossiness. The vinylidene-fluoride resin film comprises crosslinked acrylic acid ester resin particles, in which the crosslinked acrylic acid ester resin particles have an average particle diameter of 5% or more and 40% or less to the thickness of the vinylidene-fluoride resin film and the arithmetic average surface roughness (Ra) of the vinylidene-fluoride resin film is 0.4 &#x3bc;m or more and less than 2 &#x3bc;m.

Vinylidene-fluoride resin film

The present invention provides a decorative film for film insert molding, the decorative film having: a fluorine-based resin layer containing 100 to 80 parts by mass of a fluorine-based resin and 0 to 20 parts by mass of a methacrylic acid ester-based resin; an acrylic-based resin layer containing 50 to 0 parts by mass of a fluorine-based resin and 50 to 100 parts by mass of a methacrylic acid ester-based resin; and a decorative layer containing a thermoplastic resin, laminated therein in this order, wherein the fluorine-based resin layer has a thickness of 10 &#x3bc;m to 200 &#x3bc;m, and surface unevenness is formed on a surface of the fluorine-based resin layer, the surface being on the side that is not in contact with the acrylic-based resin layer. The present invention also provides a method for manufacturing the decorative film for film insert molding.

Decorative film for film insert molding and method for manufacturing same

Disclosed is a vinylidene fluoride-based resin multi-layered film including two layers composed of a front surface layer laminated on a rear surface layer, in which the front surface layer contains 80% by mass or more of a vinylidene fluoride-based resin and 20% by mass or less of a methacrylic acid ester-based resin, the degree of crystallization of the front surface layer is 45% or higher, the ratio occupied by &#x3b1;-crystals in the entire crystal component of the vinylidene fluoride-based resin is 60% or higher, the thickness of the front surface layer is 15 &#x3bc;m or more, and the rear surface layer contains 90% by mass or more of a methacrylic acid ester-based resin.

Vinylidene fluoride-based resin multi-layered film

Provided is a fluorine-based resin multilayer film for vacuum forming which does not cause wrinkles and the like when a three-dimensional surface decoration method is applied. The fluorine-based resin multilayer film for vacuum forming includes a front surface layer containing 60% by mass to 85% by mass of a vinylidene fluoride-based resin and 40% by mass to 15% by mass of a methacrylate ester-based resin; and a back surface layer containing 0% by mass to 50% by mass of a vinylidene fluoride-based resin and 100% by mass to 50% by mass of a methacrylate ester-based resin, wherein the thermal dimensional change in a film flow direction when heated at 120&#xb0; C. for 30 minutes, which is measured based on JIS K7133, is &#x2212;15% to &#x2212;2%.
