Abstract

Official abstract text for this publication.

Disclosed are a composite white pigment and a photoresist material. The composite white pigment includes particles, each of the particles includes an inner core including a non-white pigment and an outer layer including a white pigment and coating the inner core. The photoresist material includes the following components: 5 to 15 parts by weight of a photosensitizing agent, 5 to 15 parts by weight of a dispersant, 50 to 80 parts by weight of a solvent, and 5 to 15 parts by weight of the composite white pigment.

First claim

Opening claim text (preview).

The invention claimed is: 1. A photoresist material, comprising a composite white pigment, wherein the composite white pigment comprises particles, each of the particles comprising: an inner core comprising a non-white pigment, and an outer layer comprising a white pigment and coating the inner core, wherein the inner core has a particle size in a range of 0.05 to 0.08 um. 2. The photoresist material according to claim 1 , wherein the outer layer has a thickness of 0.01 to 0.025 μm. 3. The photoresist material according to claim 1 , wherein the non-white pigment is selected from a black pigment, a red pigment or a blue pigment. 4. The photoresist material according to claim 1 , wherein the composite white pigment is powdery. 5. The photoresist material according to claim 1 , wherein the particles have different shapes. 6. The photoresist material according to claim 1 , comprising: 5 to 15 parts by weight of a photosensitizing agent, 5 to 15 parts by weight of a dispersant, 50 to 80 parts by weight of a solvent, and 5 to 15 parts by weight of the composite white pigment. 7. The photoresist material according to claim 6 , comprising: 8 to 12 parts by weight of a photosensitizing agent, 8 to 12 parts by weight of a dispersant, 60 to 70 parts by weight of a solvent, and 6 to 12 parts by weight of the composite white pigment. 8. The photoresist material according to claim 1 , wherein: the particles of the composite white pigment in the photoresist material have different shapes, or the particles of the composite white pigment are spherical, and the photoresist material further comprises a white pigment having particles of irregular shapes. 9. A method of using the photoresist material according to claim 1 as a frame material of a one glass solution (OGS), comprising: coating the photoresist material onto the OGS as a frame material at a thickness of 2-3 μm. 10. A method of using a composite white pigment as a frame material of a one glass solution (OGS), comprising: coating the composite white pigment onto the OGS as a frame material at a thickness of 2-3 μm, wherein the composite white pigment comprises particles, each of the particles comprising: an inner core comprising a non-white pigment, and an outer layer comprising a white pigment and coating the inner core.
