Abstract
In order to provide an extremely cost-advantageous laminated white film for use as a recording material that is an information printing medium in place of paper such as copy paper, proposed is a laminated white film having a functional layer comprising an antistatic agent on at least one surface of a polyester film having an apparent density of 0.7 to 1.3 g/cm3 and a thickness of 10 to 1000 μm, wherein the polyester film comprises a polyester-incompatible polymer.
Claims19
A laminated white film comprising:
- a polyester film having an apparent density of 0.7 to 1.3 g/cm3 and a thickness of 10 to 1000 μm,
- a functional layer disposed on at least one surface of the polyester film, the functional layer comprising an antistatic agent and a release agent, wherein the release agent comprises a linear or branched alkyl group having 6 or more carbon atoms and is not a silicone compound,
- an image forming layer laminated on the functional layer, the image forming layer including an image forming substance and a thermoplastic resin, and
- a resin layer laminated on the image forming layer, the resin layer including a thermosetting resin layer or an active energy ray curable resin layer,
- wherein the resin layer is peelable along with the image forming substance from the functional layer, and
- the polyester film comprises two surface layers and an intermediate layer, each of the two surface layers having an arithmetic mean roughness (Ra) of 522 nm or more and 950 nm or less.

A laminated white film comprising:
- a polyester film having an apparent density of 0.7 to 1.3 g/cm3 and a thickness of 10 to 1000 μm,
- a functional layer disposed on at least on surface of the polyester film, the functional layer comprising an antistatic agent and a release agent, wherein the release agent consists of long chain alkyl group-containing quaternary ammonium salts comprising a linear or branched alkyl group having 6 or more carbon atoms, and the release agent is not a silicone compound,
- an image forming layer laminated on the functional layer, the image forming layer comprising an image forming substance and a thermoplastic resin, and
- a resin layer laminated on the image forming layer, the resin layer including a thermosetting resin layer or an active energy ray curable resin layer,
- wherein the resin layer is peelable along with the image forming substance from the functional layer.
