Abstract

The invention relates to an organosiloxane polymer, a preparation method of the organosiloxane polymer, a color photoresist containing the organosiloxane polymer, a color filter adopting the color photoresist and a preparation method of the color filter. The organosiloxane polymer can replace a levelling agent and a coupling agent in a color photoresist formula, and is superior to the traditional levelling agent or the coupling agent in the respect of a degree of polarity matching with other resins and solvents. An intramolecular pressure difference delta-F formed between double interfaces of a coated color film of the color photoresist and a substrate is controllable. The color photoresist realizes control of colloid shrinkage and forms a uniform coating having small shrinkage. The color photoresist realizes flatting of a coated color film, and good adhesiveness of pixel units and align markers on the color filter. A sample obtained by the preparation method of the color filter realizes excellent color uniformity, has high precision and prevents uneven compression of a liquid crystal display panel.

Description

technical field [0001] The present invention specifically relates to an organosiloxane high molecular polymer, a preparation method thereof, a color light blocking agent containing the polymer, a color filter made of the color light blocking agent and a preparation method of the color light filter . Background technique [0002] Color filters can be manufactured through the following process: the dispersed red (R) pigment, green (G) pigment and blue (B) pigment photoresist are coated on a glass substrate with a black matrix to form a color filter ; Vacuum and pre-baking; UV exposure under the mask; development to make graphics and post-baking to harden the film. The uniformity of the film thickness of the final sample should be controlled within 3% (tested by the 9-point method); if the uniformity exceeds a certain value, there will be no bright spots or inconsistent overall color uniformity on the LCD panel in the future, such as: Japanese patent, It is recorded in JP-P-2...
