Abstract
Provided is an anti-reflection coating composition. The anti-reflection coating composition includes an active component and a solvent B. The active component includes a matting resin A, a catalyst C, and a crosslinking agent D. The weight average molecular weight of the matting resin A is less than or equal to 20000. Also provided is use of the anti-reflection coating composition.
Claims20
An anti-reflection coating composition, comprising:
- an active component with a weight percentage from 1 wt % to 20 wt % and a solvent B with a weight percentage from 80 wt % to 99 wt %;
- wherein the active component comprises a matting resin A with a weight percentage from 50 wt % to 95 wt %, a catalyst C with a weight percentage from 1 wt % to 20 wt %, and a crosslinking agent D with a weight percentage from 3 wt % to 40 wt %;
- wherein the matting resin A is prepared by acrylic resin and a chromophoric compound, and a weight average molecular weight of the matting resin A ranges from 6000 to 20000;
- wherein polymerization monomers of the acrylic resin comprise epoxy-containing or hydroxyl-containing acrylate monomers A21;
- wherein a molar ratio of A21 to the chromophoric compound is between 1:0.8 and 1:1;
- wherein the catalyst C is an organic acid salt;
- and
- wherein the crosslinking agent D comprises a mixture of at least one member selected from a group consisting of melamine-aldehyde resin, or benzoguanamine-aldehyde resin and at least one member selected from a group consisting of glycoluril-aldehyde resin, or urea-aldehyde resin;
- and a weight ratio of at least one member selected from a group consisting of glycoluril-aldehyde resin, or urea-aldehyde resin to at least one member selected from a group consisting of melamine-aldehyde resin, or benzoguanamine-aldehyde resin is between 1:1 and 9:1.
