Definitions
- the present invention relates to an acrylic resin composition for film.
- Acrylic resin is known as one of the most weather resistant materials among plastic materials.
- a film mainly composed of methyl methacrylate is used for the purpose of laminating on various plastic materials to suppress the deterioration of weather resistance.
- an acrylic resin film made of an acrylic resin containing a rubber-like material is excellent in transparency, weather resistance, flexibility, workability, and the like. Therefore, the acrylic resin film is bonded to the surface of resin molded products, woodwork products, metal molded products, and the like, skin materials for building materials such as vehicles, furniture, door materials, window frames, baseboards, or bathroom interiors, marking films, Or it is used as a film for coating high-intensity reflectors.
- Patent Document 1 discloses the use of a low molecular weight hindered amine light stabilizer.
- low molecular weight hindered amine light stabilizers tend to have a low thermal decomposition temperature due to their low molecular weight, and bleed to rolls may be observed during film formation. In some cases, sticking to a roll may be permitted.
- an object of the present invention is to provide an acrylic resin composition for a film in which bleed to a roll is reduced when an acrylic resin film is formed.
- the present invention includes the following [1] to [15].
- An acrylic resin composition for a film comprising a high molecular weight hindered amine light stabilizer (A) having a triazine skeleton and an acrylic resin (B).

Since the tertiary octyl group is bulky, the nucleophilic reaction to the nitrogen atom is unlikely to occur, and hence the formation of bumps is unlikely to occur. In addition, since the light stabilizer has a high molecular weight, the decomposition temperature is high and bleeding is unlikely to occur.

Specifically, the produced film was passed through a roll having a speed of 5 m / min heated to 150 ° C. and wound at a speed of 5.4 m / min. Bleeding and sticking at the time of winding 1500 m were confirmed.

- ⁇ Peeling point increase rate [%] ((Peeling point at the time of 1500 m winding-Peeling point at the start of film formation) / Peeling point at the start of film formation) ⁇ 100
