Abstract
A modified acrylic resin. The modified acrylic resin comprises a transparent resin and an acrylic acid monomer having a cyclic group, and the modified acrylic resin has a low moisture adsorption. Additionally, the modified acrylic resin can be incorporated with light scattering particle and light stabilizer to provide an optical diffusing composition for use in backlight module of LCD panels.

A modified acrylic resin, comprising repeat unit (I) and repeat unit (II):
- wherein the weight ratio of the repeat unit (I) to repeat unit (II) is between 5% and 80%, and R1 and R2 each independently represent a hydrogen or alkyl group.
An optical diffusing composition, comprising 79 wt % to 99.8 wt % of a modified acrylic resin, 0.1 wt % to 20 wt % of a light scattering particle, and 0.01 wt % to 0.5 wt % of a light stabilizer, the modified acrylic resin comprises a repeat unit of repeat unit (I) and repeat unit (II):
- wherein a weight ratio of the repeat unit (I) to the repeat unit (II) is between 5% and 80%, and R1 and R2 each independently represent a hydrogen or alkyl group.
