Abstract
A kit for constructing a photographing booth, which is effective for photographing a subject to be photographed clearly. The photographing construction kit includes a box unit in a square cylindrical shape able to be folded, a lid unit in a rectangular flat plane shape, a rolled back sheet to be laid as a background of a subject to be photographed, and a roller for placing the back sheet 6 thereover. A black antireflection film is provided on a main surface side of the back sheet so that it faces the subject to be photographed. The antireflection film is configured by a membrane having a thickness of 2 μm or more and 40 μm or less formed from a liquid composition having a specific composition by spray coating.
Claims20
A kit for constructing a photographing booth used for photographing a subject to be photographed, comprising at least a back sheet arranged as a background of the subject to be photographed in a photographing space,
- wherein
- the back sheet has a black antireflection film on a main surface side, which faces the subject to be photographed;
- the antireflection film is configured by a membrane having a thickness equal to or greater than 2 μm and less than or equal to 40 μm formed from a liquid composition by spray coating;
- the liquid composition comprises at least (A), (B) and (C);
- wherein:
- (A) is a resin compound;
- (B) is either resin-type particles or inorganic-type particles,
- (B) is contained in an amount equal to or greater than 20% by mass and less than or equal to 60% by mass in a total amount of 100% by mass of all solid content in the composition;
- (B) comprises (B1) and (B2) in an amount, wherein a total amount of (B1) and (B2) in 100% by mass of (B) is equal to or great than 90% by mass, and a mass ratio of (B2) with respect to (B1 is equal to or greater than 1.8 and less than or equal to 3.3;
- (B1) is inorganic-type small particles having a particle diameter (d1) equal to or greater than 0.05 μm and less than or equal to 0.4 μm;
- (B2) is inorganic-type large particles having a particle diameter (d2) equal to or greater than 2 μm and less than or equal to 6 μm;
- and
- (C) is a diluent solvent.
