Abstract
Provided are a composition for a window film, a flexible window film formed therefrom, and a flexible display device comprising the same, wherein the composition for a window film, contains: (1) a siloxane resin comprising (R1SiO3/2)x(R2SiO3/2)y (wherein, R1 is a cross-linkable functional group, R2 is a UV absorbing functional group or a UV absorbing functional group-containing group, and 0<x<1, 0<y<1, x+y=1) and (2) an initiator.
Claims12
A composition for window films, comprising:
- a siloxane resin comprising a compound represented by Formula 1;
- and an initiator:
- (R1SiO3/2)x(R2SiO3/2)y <Formula 1>
- wherein R1 is a crosslinkable functional group;
- R2 is a UV absorption functional group or a UV absorption functional group-containing group;
- and 0<x<1, 0<y<1, and x+y=1, and
- wherein R2 comprises a group selected from an unsubstituted or substituted benzotriazole group, an unsubstituted or substituted benzophenone group, an unsubstituted or substituted hydroxybenzophenone group, an unsubstituted or substituted triazine group, an unsubstituted or substituted salicylate group, an unsubstituted or substituted cyanoacrylate group, an unsubstituted or substituted oxanilide group, an unsubstituted or substituted hydroxyphenyltriazine group, an unsubstituted or substituted hydroxyphenylbenzotriazole group, and an unsubstituted or substituted hydroxyphenylbenzophenone group.
A flexible window film comprising:
- a base layer, and
- a coating layer formed on one surface of the base layer, the coating layer formed of a composition for window films, the composition comprising:
- a siloxane resin comprising a compound represented by Formula 1;
- and an initiator:
- (R1SiO3/2)x(R2SiO3/2)y <Formula 1>
- wherein R1 is a crosslinkable functional group;
- R2 is a UV absorption functional group or a UV absorption functional group-containing group;
- and
- 0<x<1, 0<y<1, and x+y=1.
A flexible display comprising a flexible window film, the flexible window film comprising:
- a base layer, and
- a coating layer formed on one surface of the base layer, the coating layer formed of a composition for window films, the composition comprising:
- a siloxane resin comprising a compound represented by Formula 1;
- and an initiator:
- (R1SiO3/2)x(R2SiO3/2)y<Formula 1>
- wherein in Formula 1, R1 is a crosslinkable functional group;
- R2 is a UV absorption functional group or a UV absorption functional group-containing group;
- and
- 0<x<1, 0<y<1, and x+y=1.
