Abstract
Provided is a thermoplastic resin film with which a glass plate-including laminate that looks different in color tone depending on the direction or angle can be obtained. A thermoplastic resin film according to the present invention includes a thermoplastic resin and a pigment, and when the thermoplastic resin film is planarly viewed with a transmission electron microscope, a number of pigments having an aspect ratio of 3 or more and 50 or less is 3 or more and 100 or less in a rectangular region of 13 μm long and 18 μm wide.

A glass plate-including laminate comprising:
- a first glass plate;
- and
- a thermoplastic resin film,
- the thermoplastic resin film being bonded to the first glass plate,
- the thermoplastic resin film containing a thermoplastic resin and a pigment having an aspect ratio of 3 or more and 50 or less,
- the pigment in the thermoplastic resin film consisting of only one kind of pigment, an aspect ratio of the only one kind of pigment being 3 or more and 50 or less,
- wherein
- when the thermoplastic resin film is planarly viewed with a transmission electron microscope, a number of pigments having an aspect ratio of 3 or more and 50 or less is 3 or more and 100 or less in a rectangular region of 13 μm long and 18 μm wide, and
- when the laminated glass is irradiated with light from a position 100 cm apart from the laminated glass using an artificial sunlight lamp and a surface of the laminated glass irradiated with the light is rotated by 90 degrees in the planar direction of the laminated glass, a color tone of the laminated glass changes.
